The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

The strong case for Monero – fulfilling characteristics of the future currency

I wanted to write a short article about the distinct characteristics of Monero, some of which are absolutely necessities in any future currency looking to gaining serious user adoption. Together, these separate Monero quite distinctly from the rest of the crypto field.
This is certainly nothing new to the Monero seniors here, but it might contain some new perspectives, and also give an overview to the newer cryptofolk why Monero is quite unique -

1. Transactions are private by default
The sender, receiver and amount are all hidden in Monero. This is by default, as opposed to some other private cryptocurrencies, such as Zcash, where you can optionally make private transactions. As a result, most transactions in Zcash are transparent, which makes the actual anonymity set small.
In Bitcoin there is no real anonymity, because everything occurs in a transparent blockchain – the sender, receiver and amount are all public information. This has created a market for blockchain analysis, where companies keep track of the of transactions and make profit from this information. Furthermore, because the full history of sent and received Bitcoins and other transparent cryptocurrencies can be analyzed, the newly minted coins are generally more valuable than others. This phenomenon is called ‘taint’, and it exists only in transparent blockchains.
Besides speculative holding, no real-world use will emerge in any blockchain that is transparent. No company is prepared to publicly devolve how much, when and to which suppliers they send funds. Or vice versa, no company wants its competitors to know how many customers have paid them in the last quarter. Similarly, no sensible, privacy-valuing person should be willing to share his or her personal consuming habits with the whole world, forever.

2. Community-driven – no company, no CEO
Most understand cryptocurrencies are decentralized because different stakeholders all over the world participate in the process of mining, verifying and relying information from one stakeholder to another. It is practically impossible to stop this type of well distributed global network from operating.
The network topology, however, is only one part of the decentralization. If everything is controlled by a single entity, it creates a single point of failure. As an example, if everything is funded, developed and coordinated by a single company or a few companies, which funds can be seized, executives jailed and operations stopped, how secure is this cryptocurrency in the end? In Monero, there is no company, no CEO, no office. Everything is coordinated by members of the community, globally.

3. Emission is dis-inflationary and it reduces constantly
Monero’s emission, i.e. generation of new coins, reduces every block (2 minutes). In Bitcoin, the emission is reduced every four years. This causes sudden shocks to the Bitcoin ecosystem, because miners’ rewards are halved. Such a dramatic decrease will inevitably lead to some miners abandoning their mining activities. Because proof-of-work (POW) cryptocurrencies such as Bitcoin and Monero rely on miners to secure the network, any significant decrease in mining is detrimental to the network’s security. On the other hand, the smoother emission in Monero makes mining activities more stable, which improves the security and trust of the whole system.
Another future-proofing factor in Monero is the tail emission, where the block reward will no longer decrease from 0.6 XMR after mid 2022. Minimum block reward incentives miners to continue mining even if the transaction fees do not cover all economic needs of the competing miners.
Comparing this to FIAT currencies, which are inflating 2-6 % each year, Monero’s inflation is asymptotically approaching 0 %. Even though new coins are generated by every block, the amount created per given time period remains constant after mid 2022. Contrast this to the FIAT systems, where the amount of new currency created is always increasing. Due to the compounding effect even moderate inflation in FIAT currencies causes considerable losses to all savers in medium and long term.

4. Block size is dynamic – it scales with number of transactions
Monero’s block size has no cap, which means the amount of transactions that can fit to the block is not limited. To prevent transaction spamming, preventive mechanisms have been built in the protocol.
Cryptocurrencies which implement a hard cap on the block size are susceptible to surging transactions fees. This occurs when there are simply too many transactions trying to make it into the block. Such a phenomenon occurred in Bitcoin during the peak of the last bull-run in January 2018, when the average transaction fees rose above $20.

5. Fair supply – no premine or developer tax
Supply mechanism and distribution are two elemental factors, which affect how capable the cryptocurrency is as a store of value (SOV). If a large majority of the future supply is held by a small group of people, it undermines the trust that the cryptocurrency keeps its value long term. If only a few stakeholders can massively increase the supply side of the market, the downward price risk becomes high. The more distributed the supply, the more stakeholders it takes to influence it.
Two practical implementations that undermine SOV in cryptocurrencies are premine and developer tax. In premine, the founders create a large initial amount of funds for themselves (or for their organization). Premining is an issue in some POW currencies and in all proof-of-stake (POS) cryptocurrencies, because their coin generation is not done by work. Developer tax is implemented in some POW currencies, where a portion of the block reward goes to the founders.

6. Crowdfunding and voluntarism as driving forces
Since the launch of Monero in 2014, all progression has been made by its rich and versatile community. Active members consist of several PhD researchers, developers, UX designers, translators and many other professionals of varying backgrounds. Much of the work has been made possible using crowdfunding, donors being individuals, investors and companies. Some members have participated even pro-bono, which further emphasizes the community’s trust in the project. The fact that the work is enabled by crowfunding and voluntarism is truly a strength, because it is difficult to stop ideology and people who want to be part of such force. This is in stark contrast to company-driven projects, which are much more susceptible to government oversight and control.

7. Mining is more sustainable
Monero’s mining algorithm, Random X, specifically targets general purpose CPUs and it is unsuitable to be mined with application-specific integrated circuits (ASICS). This greatly improves mining decentralization, because mining is feasible on data centers and personal computers. In Bitcoin and many other POW cryptocurrencies mining is only feasible with expensive ASICS, manufactured by just a few companies.
ASIC mined cryptocurrencies are problematic because there are very few companies specializing in mining equipment. Bitcoin’s largest ASIC manufacturer, Bitmain, has had overly much power in the ecosystem. They have stalled Bitcoin’s adoption, caused division among the community and even been one of the principal culprits for the past Bitcoin forks.
Another problem with ASIC manufacturers is their economic advantage over the rest of the mining field. ASIC manufacturers typically utilize their next generation products themselves and start selling them to the consumer market after their mining profits have reduced sufficiently due to the increasing competition. This makes normal miners second tier stakeholders in the ecosystem and it is a cause of further mining centralization.

8. Proven track record
Monero community has been working actively since its inception in 2014. Majority of the work has focused on research and development, with little efforts put to marketing. Unlike some other projects, especially those forked from Bitcoin, Monero project has an extensive technical skillset in its community and it has been one of the leading projects when it comes to both innovation and execution.
One of the Monero’s focus points is applied cryptographic research. Monero has implemented several advancements into the core protocol efficiently and with assurance. All major changes to the Monero protocol have been audited by some of the world’s leading companies specializing in cryptographic analysis, funded by the Monero community.

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a
Xenolink Advisor at Epic Cash
From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.
CryptoDiffer team
Great, thank you for your answers, we now can move to community questions part!
Cryptodiffer Community
You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.
Cryptodiffer Community
To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.
Cryptodiffer Community
Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.

$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.

What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.
Cryptodiffer Community
EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.

What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability
Cryptodiffer Community
Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.

I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique
Cryptodiffer Community
Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.

If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.
Epic Cash will have its OWN Celebrities

How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.
Cryptodiffer Community
what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.

Q1 : What are your major goals to archive in the next 3–4 years?
Q2 : What are your plans to expand and gain more adoption?
Yoga Dude Pr&Marketing at Epic Cash
Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.
Cryptodiffer Community
It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.
Epic Cash is More than Money and its for Everyone.
Cryptodiffer Community
Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

  1. You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
  2. How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash
Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well.

Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.
Everyone with skin in the game gets the benefit of advancing the cause.
Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content —
https://www.youtube.com/watch?v=XtAVEqKGgqY
a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this

I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166
Max Freeman Project Lead at Epic Cash
Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project.

I wanted to write a short article about the distinct characteristics of Monero, some of which are absolutely necessities in any future currency looking to gaining serious user adoption. Together, these separate Monero quite distinctly from the rest of the crypto field.
This is certainly nothing new to the seniors here, but it might contain some new perspectives, and also give an overview to the newer cryptofolk why Monero is quite unique -

1. Transactions are private by default
The sender, receiver and amount are all hidden in Monero. This is by default, as opposed to some other private cryptocurrencies, such as Zcash, where you can optionally make private transactions. As a result, most transactions in Zcash are transparent, which makes the actual anonymity set small.
In Bitcoin there is no real anonymity, because everything occurs in a transparent blockchain – the sender, receiver and amount are all public information. This has created a market for blockchain analysis, where companies keep track of the of transactions and make profit from this information. Furthermore, because the full history of sent and received Bitcoins and other transparent cryptocurrencies can be analyzed, the newly minted coins are generally more valuable than others. This phenomenon is called ‘taint’, and it exists only in transparent blockchains.
Besides speculative holding, no real-world use will emerge in any blockchain that is transparent. No company is prepared to publicly devolve how much, when and to which suppliers they send funds. Or vice versa, no company wants its competitors to know how many customers have paid them in the last quarter. Similarly, no sensible, privacy-valuing person should be willing to share his or her personal consuming habits with the whole world, forever.

2. Community-driven – no company, no CEO
Most understand cryptocurrencies are decentralized because different stakeholders all over the world participate in the process of mining, verifying and relying information from one stakeholder to another. It is practically impossible to stop this type of well distributed global network from operating.
The network topology, however, is only one part of the decentralization. If everything is controlled by a single entity, it creates a single point of failure. As an example, if everything is funded, developed and coordinated by a single company or a few companies, which funds can be seized, executives jailed and operations stopped, how secure is this cryptocurrency in the end? In Monero, there is no company, no CEO, no office. Everything is coordinated by members of the community, globally.

3. Emission is dis-inflationary and it reduces constantly
Monero’s emission, i.e. generation of new coins, reduces every block (2 minutes). In Bitcoin, the emission is reduced every four years. This causes sudden shocks to the Bitcoin ecosystem, because miners’ rewards are halved. Such a dramatic decrease will inevitably lead to some miners abandoning their mining activities. Because proof-of-work (POW) cryptocurrencies such as Bitcoin and Monero rely on miners to secure the network, any significant decrease in mining is detrimental to the network’s security. On the other hand, the smoother emission in Monero makes mining activities more stable, which improves the security and trust of the whole system.
Another future-proofing factor in Monero is the tail emission, where the block reward will no longer decrease from 0.6 XMR after mid 2022. Minimum block reward incentives miners to continue mining even if the transaction fees do not cover all economic needs of the competing miners.
Comparing this to FIAT currencies, which are inflating 2-6 % each year, Monero’s inflation is asymptotically approaching 0 %. Even though new coins are generated by every block, the amount created per given time period remains constant after mid 2022. Contrast this to the FIAT systems, where the amount of new currency created is always increasing. Due to the compounding effect even moderate inflation in FIAT currencies causes considerable losses to all savers in medium and long term.

4. Block size is dynamic – it scales with number of transactions
Monero’s block size has no cap, which means the amount of transactions that can fit to the block is not limited. To prevent transaction spamming, preventive mechanisms have been built in the protocol.
Cryptocurrencies which implement a hard cap on the block size are susceptible to surging transactions fees. This occurs when there are simply too many transactions trying to make it into the block. Such a phenomenon occurred in Bitcoin during the peak of the last bull-run in January 2018, when the average transaction fees rose above $20.

5. Fair supply – no premine or developer tax
Supply mechanism and distribution are two elemental factors, which affect how capable the cryptocurrency is as a store of value (SOV). If a large majority of the future supply is held by a small group of people, it undermines the trust that the cryptocurrency keeps its value long term. If only a few stakeholders can massively increase the supply side of the market, the downward price risk becomes high. The more distributed the supply, the more stakeholders it takes to influence it.
Two practical implementations that undermine SOV in cryptocurrencies are premine and developer tax. In premine, the founders create a large initial amount of funds for themselves (or for their organization). Premining is an issue in some POW currencies and in all proof-of-stake (POS) cryptocurrencies, because their coin generation is not done by work. Developer tax is implemented in some POW currencies, where a portion of the block reward goes to the founders.

6. Crowdfunding and voluntarism as driving forces
Since the launch of Monero in 2014, all progression has been made by its rich and versatile community. Active members consist of several PhD researchers, developers, UX designers, translators and many other professionals of varying backgrounds. Much of the work has been made possible using crowdfunding, donors being individuals, investors and companies. Some members have participated even pro-bono, which further emphasizes the community’s trust in the project. The fact that the work is enabled by crowfunding and voluntarism is truly a strength, because it is difficult to stop ideology and people who want to be part of such force. This is in stark contrast to company-driven projects, which are much more susceptible to government oversight and control.

7. Mining is more sustainable
Monero’s mining algorithm, Random X, specifically targets general purpose CPUs and it is unsuitable to be mined with application-specific integrated circuits (ASICS). This greatly improves mining decentralization, because mining is feasible on data centers and personal computers. In Bitcoin and many other POW cryptocurrencies mining is only feasible with expensive ASICS, manufactured by just a few companies.
ASIC mined cryptocurrencies are problematic because there are very few companies specializing in mining equipment. Bitcoin’s largest ASIC manufacturer, Bitmain, has had overly much power in the ecosystem. They have stalled Bitcoin’s adoption, caused division among the community and even been one of the principal culprits for the past Bitcoin forks.
Another problem with ASIC manufacturers is their economic advantage over the rest of the mining field. ASIC manufacturers typically utilize their next generation products themselves and start selling them to the consumer market after their mining profits have reduced sufficiently due to the increasing competition. This makes normal miners second tier stakeholders in the ecosystem and it is a cause of further mining centralization.

8. Proven track record
Monero community has been working actively since its inception in 2014. Majority of the work has focused on research and development, with little efforts put to marketing. Unlike some other projects, especially those forked from Bitcoin, Monero project has an extensive technical skillset in its community and it has been one of the leading projects when it comes to both innovation and execution.
One of the Monero’s focus points is applied cryptographic research. Monero has implemented several advancements into the core protocol efficiently and with assurance. All major changes to the Monero protocol have been audited by some of the world’s leading companies specializing in cryptographic analysis, funded by the Monero community.

Your Guide to Monero, and Why It Has Great Potential

/////Your Guide to Monero, and Why It Has Great Potential/////

Marketing.
It's a dirty word for most members of the Monero community.
It is also one of the most divisive words in the Monero community. Yet, the lack of marketing is one of the most frustrating things for many newcomers.
This is what makes this an unusual post from a member of the Monero community.
This post is an unabashed and unsolicited analyzation of why I believe Monero to have great potential.
Below I have attempted to outline different reasons why Monero has great potential, beginning with upcoming developments and use cases, to broader economic motives, speculation, and key issues for it to overcome.
I encourage you to discuss and criticise my musings, commenting below if you feel necessary to do so.

///Upcoming Developments///

Bulletproofs - A Reduction in Transaction Sizes and Fees
Since the introduction of Ring Confidential Transactions (Ring CT), transaction amounts have been hidden in Monero, albeit at the cost of increased transaction fees and sizes. In order to mitigate this issue, Bulletproofs will soon be added to reduce both fees and transaction size by 80% to 90%. This is great news for those transacting smaller USD amounts as people commonly complained Monero's fees were too high! Not any longer though! More information can be found here. Bulletproofs are already working on the Monero testnet, and developers were aiming to introduce them in March 2018, however it could be delayed in order to ensure everything is tried and tested.
Multisig
Multisig has recently been merged! Mulitsig, also called multisignature, is the requirement for a transaction to have two or more signatures before it can be executed. Multisig transactions and addresses are indistinguishable from normal transactions and addresses in Monero, and provide more security than single-signature transactions. It is believed this will lead to additional marketplaces and exchanges to supporting Monero.
Kovri
Kovri is an implementation of the Invisible Internet Project (I2P) network. Kovri uses both garlic encryption and garlic routing to create a private, protected overlay-network across the internet. This overlay-network provides users with the ability to effectively hide their geographical location and internet IP address. The good news is Kovri is under heavy development and will be available soon. Unlike other coins' false privacy claims, Kovri is a game changer as it will further elevate Monero as the king of privacy.
Mobile Wallets
There is already a working Android Wallet called Monerujo available in the Google Play Store. X Wallet is an IOS mobile wallet. One of the X Wallet developers recently announced they are very, very close to being listed in the Apple App Store, however are having some issues with getting it approved. The official Monero IOS and Android wallets, along with the MyMonero IOS and Android wallets, are also almost ready to be released, and can be expected very soon.
Hardware Wallets
Hardware wallets are currently being developed and nearing completion. Because Monero is based on the CryptoNote protocol, it means it requires unique development in order to allow hardware wallet integration. The Ledger Nano S will be adding Monero support by the end of Q1 2018. There is a recent update here too. Even better, for the first time ever in cryptocurrency history, the Monero community banded together to fund the development of an exclusive Monero Hardware Wallet, and will be available in Q2 2018, costing only about $20! In addition, the CEO of Trezor has offered a 10BTC bounty to whoever can provide the software to allow Monero integration. Someone can be seen to already be working on that here.
TAILS Operating System Integration
Monero is in the progress of being packaged in order for it to be integrated into TAILS and ready to use upon install. TAILS is the operating system popularised by Edward Snowden and is commonly used by those requiring privacy such as journalists wanting to protect themselves and sources, human-right defenders organizing in repressive contexts, citizens facing national emergencies, domestic violence survivors escaping from their abusers, and consequently, darknet market users.
In the meantime, for those users who wish to use TAILS with Monero, u/Electric_sheep01 has provided Sheep's Noob guide to Monero GUI in Tails 3.2, which is a step-by-step guide with screenshots explaining how to setup Monero in TAILS, and is very easy to follow.
Mandatory Hardforks
Unlike other coins, Monero receives a protocol upgrade every 6 months in March and September. Think of it as a Consensus Protocol Update. Monero's hard forks ensure quality development takes place, while preventing political or ideological issues from hindering progress. When a hardfork occurs, you simply download and use the new daemon version, and your existing wallet files and copy of the blockchain remain compatible. This reddit post provides more information.
Dynamic fees
Many cryptocurrencies have an arbitrary block size limit. Although Monero has a limit, it is adaptive based on the past 100 blocks. Similarly, fees change based on transaction volume. As more transactions are processed on the Monero network, the block size limit slowly increases and the fees slowly decrease. The opposite effect also holds true. This means that the more transactions that take place, the cheaper the fees!
Tail Emission and Inflation
There will be around 18.4 million Monero mined at the end of May 2022. However, tail emission will kick in after that which is 0.6 XMR, so it has no fixed limit. Gundamlancer explains that Monero's "main emission curve will issue about 18.4 million coins to be mined in approximately 8 years. (more precisely 18.132 Million coins by ca. end of May 2022) After that, a constant "tail emission" of 0.6 XMR per 2-minutes block (modified from initially equivalent 0.3 XMR per 1-minute block) will create a sub-1% perpetual inflatio starting with 0.87% yearly inflation around May 2022) to prevent the lack of incentives for miners once a currency is not mineable anymore.
Monero Research Lab
Monero has a group of anonymous/pseudo-anonymous university academics actively researching, developing, and publishing academic papers in order to improve Monero. See here and here. The Monero Research Lab are acquainted with other members of cryptocurrency academic community to ensure when new research or technology is uncovered, it can be reviewed and decided upon whether it would be beneficial to Monero. This ensures Monero will always remain a leading cryptocurrency. A recent end of 2017 update from a MRL researcher can be found here.

///Monero's Technology - Rising Above The Rest///

Monero Has Already Proven Itself To Be Private, Secure, Untraceable, and Trustless
Monero is the only private, untraceable, trustless, secure and fungible cryptocurrency. Bitcoin and other cryptocurrencies are TRACEABLE through the use of blockchain analytics, and has lead to the prosecution of numerous individuals, such as the alleged Alphabay administrator Alexandre Cazes. In the Forfeiture Complaint which detailed the asset seizure of Alexandre Cazes, the anonymity capabilities of Monero were self-demonstrated by the following statement of the officials after the AlphaBay shutdown: "In total, from CAZES' wallets and computer agents took control of approximately $8,800,000 in Bitcoin, Ethereum, Monero and Zcash, broken down as follows: 1,605.0503851 Bitcoin, 8,309.271639 Ethereum, 3,691.98 Zcash, and an unknown amount of Monero".
Privacy CANNOT BE OPTIONAL and must be at a PROTOCOL LEVEL. With Monero, privacy is mandatory, so that everyone gets the benefits of privacy without any transactions standing out as suspicious. This is the reason Darknet Market places are moving to Monero, and will never use Verge, Zcash, Dash, Pivx, Sumo, Spectre, Hush or any other coins that lack good privacy. Peter Todd (who was involved in the Zcash trusted setup ceremony) recently reiterated his concerns of optional privacy after Jeffrey Quesnelle published his recent paper stating 31.5% of Zcash transactions may be traceable, and that only ~1% of the transactions are pure privacy transactions (i.e., z -> z transactions). When the attempted private transactions stand out like a sore thumb there is no privacy, hence why privacy cannot be optional. In addition, in order for a cryptocurrency to truly be private, it must not be controlled by a centralised body, such as a company or organisation, because it opens it up to government control and restrictions. This is no joke, but Zcash is supported by DARPA and the Israeli government!.
Monero provides a stark contrast compared to other supposed privacy coins, in that Monero does not have a rich list! With all other coins, you can view wallet balances on the blockexplorers. You can view Monero's non-existent rich list here to see for yourself.
I will reiterate here that Monero is TRUSTLESS. You don't need to rely on anyone else to protect your privacy, or worry about others colluding to learn more about you. No one can censor your transaction or decide to intervene. Monero is immutable, unlike Zcash, in which the lead developer Zooko publicly tweeted the possibility of providing a backdoor for authorities to trace transactions. To Zcash's demise, Zooko famously tweeted:
" And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible. …"
Ethereum's track record of immutability is also poor. Ethereum was supposed to be an immutable blockchain ledger, however after the DAO hack this proved to not be the case. A 2016 article on Saintly Law summarised the problematic nature of Ethereum's leadership and blockchain intervention:
" Many ethereum and blockchain advocates believe that the intervention was the wrong move to make in this situation. Smart contracts are meant to be self-executing, immutable and free from disturbance by organisations and intermediaries. Yet the building block of all smart contracts, the code, is inherently imperfect. This means that the technology is vulnerable to the same malicious hackers that are targeting businesses and governments. It is also clear that the large scale intervention after the DAO hack could not and would not likely be taken in smaller transactions, as they greatly undermine the viability of the cryptocurrency and the technology."
Monero provides Fungibility and Privacy in a Cashless World
As outlined on GetMonero.org, fungibility is the property of a currency whereby two units can be substituted in place of one another. Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold. Monero is fungible due to the nature of the currency which provides no way to link transactions together nor trace the history of any particular XMR. 1 XMR is functionally identical to any other 1 XMR. Fungibility is an advantage Monero has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Monero blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation coinbase transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the blockchain in perpetuity.
A great example of Bitcoin's lack of fungibility was reposted by u/ViolentlyPeaceful:
"Imagine you sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity. Now you are worried that you have become a suspect in a criminal case, because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment."
This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Monero has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Monero is truly fungible and there can be no blacklisting of certain XMR, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain.
The world is moving cashless. Fact. The ramifications of this are enormous as we move into a cashless world in which transactions will be tracked and there is a potential for data to be used by third parties for adverse purposes. While most new cryptocurrency investors speculate upon vaporware ICO tokens in the hope of generating wealth, Monero provides salvation for those in which financial privacy is paramount. Too often people equate Monero's features with criminal endeavors. Privacy is not a crime, and is necessary for good money. Transparency in Monero is possible OFF-CHAIN, which offers greater transparency and flexibility. For example, a Monero user may share their Private View Key with their accountant for tax purposes.
Monero aims to be adopted by more than just those with nefarious use cases. For example, if you lived in an oppressive religious regime and wanted to buy a certain item, using Monero would allow you to exchange value privately and across borders if needed. Another example is that if everybody can see how much cryptocurrency you have in your wallet, then a certain service might decide to charge you more, and bad actors could even use knowledge of your wallet balance to target you for extortion purposes. For example, a Russian cryptocurrency blogger was recently beaten and robbed of $425k. This is why FUNGIBILITY IS ESSENTIAL. To summarise this in a nutshell:
"A lack of fungibility means that when sending or receiving funds, if the other person personally knows you during a transaction, or can get any sort of information on you, or if you provide a residential address for shipping etc. – you could quite potentially have them use this against you for personal gain"
For those that wish to seek more information about why Monero is a superior form of money, read The Merits of Monero: Why Monero Vs Bitcoin over on the Monero.how website.
Monero's Humble Origins
Something that still rings true today despite the great influx of money into cryptocurrencies was outlined in Nick Tomaino's early 2016 opinion piece. The author claimed that "one of the most interesting aspects of Monero is that the project has gained traction without a crowd sale pre-launch, without VC funding and any company or well-known investors and without a pre-mine. Like Bitcoin in the early days, Monero has been a purely grassroots movement that was bootstrapped by the creator and adopted organically without any institutional buy-in. The creator and most of the core developers serve the community pseudonymously and the project was launched on a message board (similar to the way Bitcoin was launched on an email newsletter)."
The Organic Growth of the Monero Community
The Monero community over at monero is exponentially growing. You can view the Monero reddit metrics here and see that the Monero subreddit currently gains more than 10,000 (yes, ten thousand!) new subscribers every 10 days! Compare this to most of the other coins out there, and it proves to be one of the only projects with real organic growth. In addition to this, the community subreddits are specifically divided to ensure the main subreddit remains unbiased, tech focused, with no shilling or hype. All trading talk is designated to xmrtrader, and all memes at moonero.
Forum Funding System
While most contributors have gratefully volunteered their time to the project, Monero also has a Forum Funding System in which money is donated by community members to ensure it attracts and retains the brightest minds and most skilled developers. Unlike ICOs and other cryptocurrencies, Monero never had a premine, and does not have a developer tax. If ANYONE requires funding for a Monero related project, then they can simply request funding from the community, and if the community sees it as beneficial, they will donate. Types of projects range from Monero funding for local meet ups, to paying developers for their work.
Monero For Goods, Services, and Market Places
There is a growing number of online goods and services that you can now pay for with Monero. Globee is a service that allows online merchants to accept payments through credit cards and a host of cryptocurrencies, while being settled in Bitcoin, Monero or fiat currency. Merchants can reach a wider variety of customers, while not needing to invest in additional hardware to run cryptocurrency wallets or accept the current instability of the cryptocurrency market. Globee uses all of the open source API's that BitPay does making integrations much easier!
Project Coral Reef is a service which allows you to shop and pay for popular music band products and services using Monero.
Linux, Veracrypt, and a whole array of VPNs now accept Monero.
There is a new Monero only marketplace called Annularis currently being developed which has been created for those who value financial privacy and economic freedom, and there are rumours Open Bazaar is likely to support Monero once Multisig is implemented.
In addition, Monero is also supported by The Living Room of Satoshi so you can pay bills or credit cards directly using Monero.
Monero can be found on a growing number of cryptocurrency exchange services such as Bittrex, Poloniex, Cryptopia, Shapeshift, Changelly, Bitfinex, Kraken, Bisq, Tux, and many others.
For those wishing to purchase Monero anonymously, there are services such as LocalMonero.co and Moneroforcash.com.
With XMR.TO you can pay Bitcoin addresses directly with Monero. There are no other fees than the miner ones. All user records are purged after 48 hours. XMR.TO has also been added as an embedded feature into the Monerujo android wallet.
Coinhive Browser-Based Mining
Unlike Bitcoin, Monero can be mined using CPUs and GPUs. Not only does this encourage decentralisation, it also opens the door to browser based mining. Enter side of stage, Coinhive browser-based mining. As described by Hon Lau on the Symnatec Blog Browser-based mining, as its name suggests, is a method of cryptocurrency mining that happens inside a browser and is implemented using Javascript. Coinhive is marketed as an alternative to browser ad revenue. The motivation behind this is simple: users pay for the content indirectly by coin mining when they visit the site and website owners don't have to bother users with sites laden with ads, trackers, and all the associated paraphern. This is great, provided that the websites are transparent with site visitors and notify users of the mining that will be taking place, or better still, offer users a way to opt in, although this hasn't always been the case thus far.
Skepticism Sunday
The main Monero subreddit has weekly Skepticism Sundays which was created with the purpose of installing "a culture of being scientific, skeptical, and rational". This is used to have open, critical discussions about monero as a technology, it's economics, and so on.

///Speculation///

Major Investors And Crypto Figureheads Are Interested
Ari Paul is the co-founder and CIO of BlockTower Capital. He was previously a portfolio manager for the University of Chicago's $8 billion endowment, and a derivatives market maker and proprietary trader for Susquehanna International Group. Paul was interviewed on CNBC on the 26th of December and when asked what was his favourite coin was, he stated "One that has real fundamental value besides from Bitcoin is Monero" and said it has "very strong engineering". In addition, when he was asked if that was the one used by criminals, he replied "Everything is used by criminals including the US dollar and the Euro". Paul later supported these claims on Twitter, recommending only Bitcoin and Monero as long-term investments.
There are reports that "Roger Ver, earlier known as 'Bitcoin Jesus' for his evangelical support of the Bitcoin during its early years, said his investment in Monero is 'substantial' and his biggest in any virtual currency since Bitcoin.
Charlie Lee, the creator of Litecoin, has publicly stated his appreciation of Monero. In a September 2017 tweet directed to Edward Snowden explaining why Monero is superior to Zcash, Charlie Lee tweeted:
All private transactions, More tested privacy tech, No tax on miners to pay investors, No high inflation... better investment.
John McAfee, arguably cryptocurrency's most controversial character at the moment, has publicly supported Monero numerous times over the last twelve months(before he started shilling ICOs), and has even claimed it will overtake Bitcoin.
Playboy instagram celebrity Dan Bilzerian is a Monero investor, with 15% of his portfolio made up of Monero.
Finally, while he may not be considered a major investor or figurehead, Erik Finman, a young early Bitcoin investor and multimillionaire, recently appeared in a CNBC Crypto video interview, explaining why he isn't entirely sold on Bitcoin anymore, and expresses his interest in Monero, stating:
"Monero is a really good one. Monero is an incredible currency, it's completely private."
There is a common belief that most of the money in cryptocurrency is still chasing the quick pump and dumps, however as the market matures, more money will flow into legitimate projects such as Monero. Monero's organic growth in price is evidence smart money is aware of Monero and gradually filtering in.
The Bitcoin Flaw
A relatively unknown blogger named CryptoIzzy posted three poignant pieces regarding Monero and its place in the world. The Bitcoin Flaw: Monero Rising provides an intellectual comparison of Monero to other cryptocurrencies, and Valuing Cryptocurrencies: An Approach outlines methods of valuing different coins.
CryptoIzzy's most recent blog published only yesterday titled Monero Valuation - Update and Refocus is a highly recommended read. It touches on why Monero is much more than just a coin for the Darknet Markets, and provides a calculated future price of Monero.
CryptoIzzy also published The Power of Money: A Case for Bitcoin, which is an exploration of our monetary system, and the impact decentralised cryptocurrencies such as Bitcoin and Monero will have on the world. In the epilogue the author also provides a positive and detailed future valuation based on empirical evidence. CryptoIzzy predicts Monero to easily progress well into the four figure range.
Monero Has a Relatively Small Marketcap
Recently we have witnessed many newcomers to cryptocurrency neglecting to take into account coins' marketcap and circulating supply, blindly throwing money at coins under $5 with inflated marketcaps and large circulating supplies, and then believing it's possible for them to reach $100 because someone posted about it on Facebook or Reddit.
Compared to other cryptocurrencies, Monero still has a low marketcap, which means there is great potential for the price to multiply. At the time of writing, according to CoinMarketCap, Monero's marketcap is only a little over $5 billion, with a circulating supply of 15.6 million Monero, at a price of $322 per coin.
For this reason, I would argue that this is evidence Monero is grossly undervalued. Just a few billion dollars of new money invested in Monero can cause significant price increases. Monero's marketcap only needs to increase to ~$16 billion and the price will triple to over $1000. If Monero's marketcap simply reached ~$35 billion (just over half of Ripple's $55 billion marketcap), Monero's price will increase 600% to over $2000 per coin.
Another way of looking at this is Monero's marketcap only requires ~$30 billion of new investor money to see the price per Monero reach $2000, while for Ethereum to reach $2000, Ethereum's marketcap requires a whopping ~$100 billion of new investor money.
Technical Analysis
There are numerous Monero technical analysts, however none more eerily on point than the crowd-pleasing Ero23. Ero23's charts and analysis can be found on Trading View. Ero23 gained notoriety for his long-term Bitcoin bull chart published in February, which is still in play today. Head over to his Trading View page to see his chart: Monero's dwindling supply. $10k in 2019 scenario, in which Ero23 predicts Monero to reach $10,000 in 2019. There is also this chart which appears to be freakishly accurate and is tracking along perfectly today.
Coinbase Rumours
Over the past 12 months there have been ongoing rumours that Monero will be one of the next cryptocurrencies to be added to Coinbase. In January 2017, Monero Core team member Riccardo 'Fluffypony' Spagni presented a talk at Coinbase HQ. In addition, in November 2017 GDAX announced the GDAX Digit Asset Framework outlining specific parameters cryptocurrencies must meet in order to be added to the exchange. There is speculation that when Monero has numerous mobile and hardware wallets available, and multisig is working, then it will be added. This would enable public accessibility to Monero to increase dramatically as Coinbase had in excess of 13 million users as of December, and is only going to grow as demand for cryptocurrencies increases. Many users argue that due to KYC/AML regulations, Coinbase will never be able to add Monero, however the Kraken exchange already operates in the US and has XMfiat pairs, so this is unlikely to be the reason Coinbase is yet to implement XMfiat trading.
Monero Is Not an ICO Scam
It is likely most of the ICOs which newcomers invest in, hoping to get rich quick, won't even be in the Top 100 cryptocurrencies next year. A large portion are most likely to be pumps and dumps, and we have already seen numerous instances of ICO exit scams. Once an ICO raises millions of dollars, the developers or CEO of the company have little incentive to bother rolling out their product or service when they can just cash out and leave. The majority of people who create a company to provide a service or product, do so in order to generate wealth. Unless these developers and CEOs are committed and believed in their product or service, it's likely that the funds raised during the ICO will far exceed any revenue generated from real world use cases.
Monero is a Working Currency, Today
Monero is a working currency, here today.
The majority of so called cryptocurrencies that exist today are not true currencies, and do not aim to be. They are a token of exchange. They are like a share in a start-up company hoping to use blockchain technology to succeed in business. A crypto-assest is a more accurate name for coins such as Ethereum, Neo, Cardano, Vechain, etc.
Monero isn't just a vaporware ICO token that promises to provide a blockchain service in the future. It is not a platform for apps. It is not a pump and dump coin.
Monero is the only coin with all the necessary properties to be called true money.
Monero is private internet money.
Some even describe Monero as an online Swiss Bank Account or Bitcoin 2.0, and it is here to continue on from Bitcoin's legacy.
Monero is alleviating the public from the grips of banks, and protests the monetary system forced upon us.
Monero only achieved this because it is the heart and soul, and blood, sweat, and tears of the contributors to this project. Monero supporters are passionate, and Monero has gotten to where it is today thanks to its contributors and users.

///Key Issues for Monero to Overcome///

Scalability
While Bulletproofs are soon to be implemented in order to improve Monero's transaction sizes and fees, scalability is an issue for Monero that is continuously being assessed by Monero's researchers and developers to find the most appropriate solution. Ricardo 'Fluffypony' Spagni recently appeared on CNBC's Crypto Trader, and when asked whether Monero is scalable as it stands today, Spagni stated that presently, Monero's on-chain scaling is horrible and transactions are larger than Bitcoin's (because of Monero's privacy features), so side-chain scaling may be more efficient. Spagni elaborated that the Monero team is, and will always be, looking for solutions to an array of different on-chain and off-chain scaling options, such as developing a Mimblewimble side-chain, exploring the possibility of Lightning Network so atomic swaps can be performed, and Tumblebit.
In a post on the Monero subreddit from roughly a month ago, monero moderator u/dEBRUYNE_1 supports Spagni's statements. dEBRUYNE_1 clarifies the issue of scalability:
"In Bitcoin, the main chain is constrained and fees are ludicrous. This results in users being pushed to second layer stuff (e.g. sidechains, lightning network). Users do not have optionality in Bitcoin. In Monero, the goal is to make the main-chain accessible to everyone by keeping fees reasonable. We want users to have optionality, i.e., let them choose whether they'd like to use the main chain or second layer stuff. We don't want to take that optionality away from them."
When the Spagni CNBC video was recently linked to the Monero subreddit, it was met with lengthy debate and discussion from both users and developers. u/ferretinjapan summarised the issue explaining:
"Monero has all the mechanisms it needs to find the balance between transaction load, and offsetting the costs of miner infrastructure/profits, while making sure the network is useful for users. But like the interviewer said, the question is directed at "right now", and Fluffys right to a certain extent, Monero's transactions are huge, and compromises in blockchain security will help facilitate less burdensome transactional activity in the future. But to compare Monero to Bitcoin's transaction sizes is somewhat silly as Bitcoin is nowhere near as useful as monero, and utility will facilitate infrastructure building that may eventually utterly dwarf Bitcoin. And to equate scaling based on a node being run on a desktop being the only option for what classifies as "scalable" is also an incredibly narrow interpretation of the network being able to scale, or not. Given the extremely narrow definition of scaling people love to (incorrectly) use, I consider that a pretty crap question to put to Fluffy in the first place, but... ¯_(ツ)_/¯"
u/xmrusher also contributed to the discussion, comparing Bitcoin to Monero using this analogous description:
"While John is much heavier than Henry, he's still able to run faster, because, unlike Henry, he didn't chop off his own legs just so the local wheelchair manufacturer can make money. While Morono has much larger transactions then Bitcoin, it still scales better, because, unlike Bitcoin, it hasn't limited itself to a cripplingly tiny blocksize just to allow Blockstream to make money."
Setting up a wallet can still be time consuming
It's time consuming and can be somewhat difficult for new cryptocurrency users to set up their own wallet using the GUI wallet or the Command Line Wallet. In order to strengthen and further decentralize the Monero network, users are encouraged to run a full node for their wallet, however this can be an issue because it can take up to 24-48 hours for some users depending on their hard-drive and internet speeds. To mitigate this issue, users can run a remote node, meaning they can remotely connect their wallet to another node in order to perform transactions, and in the meantime continue to sync the daemon so in the future they can then use their own node.
For users that do run into wallet setup issues, or any other problems for that matter, there is an extremely helpful troubleshooting thread on the Monero subreddit which can be found here. And not only that, unlike some other cryptocurrency subreddits, if you ask a question, there is always a friendly community member who will happily assist you. Monero.how is a fantastic resource too!
Despite still being difficult to use, the user-base and price may increase dramatically once it is easier to use. In addition, others believe that when hardware wallets are available more users will shift to Monero.

///Conclusion///

I actually still feel a little shameful for promoting Monero here, but feel a sense of duty to do so.
Monero is transitioning into an unstoppable altruistic beast. This year offers the implementation of many great developments, accompanied by the likelihood of a dramatic increase in price.
I request you discuss this post, point out any errors I have made, or any information I may have neglected to include. Also, if you believe in the Monero project, I encourage you to join your local Facebook or Reddit cryptocurrency group and spread the word of Monero. You could even link this post there to bring awareness to new cryptocurrency users and investors.
I will leave you with an old on-going joke within the Monero community - Don't buy Monero - unless you have a use case for it of course :-) Just think to yourself though - Do I have a use case for Monero in our unpredictable Huxleyan society? Hint: The answer is ?

The method by which the block chain is analysed to determine which bitcoin addresses are related to others is called taint analysis. If a person of interest is performing trait analysis on addresses, it may mean that they have performed bitcoin mixing and they wish to check that it was successful.

Blockchain.info offers a service that will calculate taint, but I've found no good explanation for how taint is calculated.. The best (and only) explanation I've found so far appears in the paper Anonymity of Bitcoin Transactions:. The taint analysis works by calculating the percentage of the amount of bitcoins that might origin from ... In this case of Bitcoins, taint is simply a measure of correlation between two (wallet) addresses. The variable expressed as taint is primarily used to express this wallet connection.
