Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses. Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes. First, some background. Here is a summary of how custodians make us more secure: Previously, we might give Alice our crypto assets to hold. There were risks:
Alice might take the assets and disappear.
Alice might spend the assets and pretend that she still has them (fractional model).
Alice might store the assets insecurely and they'll get stolen.
Alice might give the assets to someone else by mistake or by force.
Alice might lose access to the assets.
But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
Alice can't take the assets and disappear (unless she asks Bob or never gives them to Bob).
Alice can't spend the assets and pretend that she still has them. (Unless she didn't give them to Bob or asks him for them.)
Alice can't store the assets insecurely so they get stolen. (After all - she doesn't have any control over the withdrawal process from any of Bob's systems, right?)
Alice can't give the assets to someone else by mistake or by force. (Bob will stop her, right Bob?)
Alice can't lose access to the funds. (She'll always be present, sane, and remember all secrets, right?)
See - all problems are solved! All we have to worry about now is:
Bob might take the assets and disappear.
Bob might spend the assets and pretend that he still has them (fractional model).
Bob might store the assets insecurely and they'll get stolen.
Bob might give the assets to someone else by mistake or by force.
Bob might lose access to the assets.
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are! "On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid". "Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since." "As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!" "Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?" "Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party." "Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!" "What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven." "Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!" "We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies. And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often". How many holes have to exist for your funds to get stolen? Just one. Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so? If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security. The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle. And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet? Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds. So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
ANY CERTAINTY BALANCES WEREN'T EXCLUDED. Quadriga's largest account was $70m. 80% of funds are in 20% of accounts (Pareto principle). All it takes is excluding a few really large accounts - and nobody's the wiser. A fractional platform can easily pass any audit this way.
ANY VISIBILITY WHATSOEVER INTO THE CUSTODIANS. BitBuy put out their report before moving all the funds to their custodian and ShakePay apparently can't even tell us who the custodian is. That's pretty important considering that basically all of the funds are now stored there.
ANY IDEA ABOUT THE OTHER EXCHANGES. In order for this to be effective, it has to be the norm. It needs to be "unusual" not to know. If obscurity is the norm, then it's super easy for people like Gerald Cotten and Dave Smilie to blend right in.
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
First report within 1 month of launching, another within 3 months, and further reports at minimum every 6 months thereafter.
No auditor can be repeated within a 12 month period.
All reports must be public, identifying the auditor and the full methodology used.
All auditors must be independent of the firm being audited with no conflict of interest.
Reports must include the percentage of each asset backed, and how it's backed.
The auditor publishes a hash list, which lists a hash of each customer's information and balances that were included. Hash is one-way encryption so privacy is fully preserved. Every customer can use this to have 100% confidence they were included.
If we want more extensive requirements on audits, these should scale upward based on the total assets at risk on the platform, and whether the platform has loaned their assets out.
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever. Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see. It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation. A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7. History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance. Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.) Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive. Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today. Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well. Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do. Facts/background/sources (skip if you like):
The inspiration for the paragraph about splitting wallets was an actual quote from a Canadian company providing custodial services in response to the OSC consultation paper: "We believe that it will be in the in best interests of investors to prohibit pooled crypto assets or ‘floats’. Most Platforms pool assets, citing reasons of practicality and expense. The recent hack of the world’s largest Platform – Binance – demonstrates the vulnerability of participants’ assets when such concessions are made. In this instance, the Platform’s entire hot wallet of Bitcoins, worth over $40 million, was stolen, facilitated in part by the pooling of client crypto assets." "the maintenance of participants (and Platform) crypto assets across multiple wallets distributes the related risk and responsibility of security - reducing the amount of insurance coverage required and making insurance coverage more readily obtainable". For the record, their reply also said nothing whatsoever about multi-sig or offline storage.
In addition to the fact that the $40m hack represented only one "hot wallet" of Binance, and they actually had the vast majority of assets in other wallets (including mostly cold wallets), multiple real cases have clearly demonstrated that risk is still present with multiple wallets. Bitfinex, VinDAX, Bithumb, Altsbit, BitPoint, Cryptopia, and just recently KuCoin all had multiple wallets breached all at the same time, and may represent a significantly larger impact on customers than the Binance breach which was fully covered by Binance. To represent that simply having multiple separate wallets under the same security scheme is a comprehensive way to reduce risk is just not true.
Private insurance has historically never covered a single loss in the cryptocurrency space (at least, not one that I was able to find), and there are notable cases where massive losses were not covered by insurance. Bitpay in 2015 and Yapizon in 2017 both had insurance policies that didn't pay out during the breach, even after a lengthly court process. The same insurance that ShakePay is presently using (and announced to much fanfare) was describe by their CEO himself as covering “physical theft of the media where the private keys are held,” which is something that has never historically happened. As was said with regard to the same policy in 2018 - “I don’t find it surprising that Lloyd’s is in this space,” said Johnson, adding that to his mind the challenge for everybody is figuring out how to structure these policies so that they are actually protective. “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.”
The most profitable policy for a private insurance company is one with the most expensive premiums that they never have to pay a claim on. They have no inherent incentive to take care of people who lost funds. It's "cheaper" to take the reputational hit and fight the claim in court. The more money at stake, the more the insurance provider is incentivized to avoid payout. They're not going to insure the assets unless they have reasonable certainty to make a profit by doing so, and they're not going to pay out a massive sum unless it's legally forced. Private insurance is always structured to be maximally profitable to the insurance provider.
The circumvention of multi-sig was a key factor in the massive Bitfinex hack of over $60m of bitcoin, which today still sits being slowly used and is worth over $3b. While Bitfinex used a qualified custodian Bitgo, which was and still is active and one of the industry leaders of custodians, and they set up 2 of 3 multi-sig wallets, the entire system was routed through Bitfinex, such that Bitfinex customers could initiate the withdrawals in a "hot" fashion. This feature was also a hit with the hacker. The multi-sig was fully circumvented.
Bitpay in 2015 was another example of a breach that stole 5,000 bitcoins. This happened not through the exploit of any system in Bitpay, but because the CEO of a company they worked with got their computer hacked and the hackers were able to request multiple bitcoin purchases, which Bitpay honoured because they came from the customer's computer legitimately. Impersonation is a very common tactic used by fraudsters, and methods get more extreme all the time.
A notable case in Canada was the Canadian Bitcoins exploit. Funds were stored on a server in a Rogers Data Center, and the attendee was successfully convinced to reboot the server "in safe mode" with a simple phone call, thus bypassing the extensive security and enabling the theft.
The very nature of custodians circumvents multi-sig. This is because custodians are not just having to secure the assets against some sort of physical breach but against any form of social engineering, modification of orders, fraudulent withdrawal attempts, etc... If the security practices of signatories in a multi-sig arrangement are such that the breach risk of one signatory is 1 in 100, the requirement of 3 independent signatures makes the risk of theft 1 in 1,000,000. Since hackers tend to exploit the weakest link, a comparable custodian has to make the entry and exit points of their platform 10,000 times more secure than one of those signatories to provide equivalent protection. And if the signatories beef up their security by only 10x, the risk is now 1 in 1,000,000,000. The custodian has to be 1,000,000 times more secure. The larger and more complex a system is, the more potential vulnerabilities exist in it, and the fewer people can understand how the system works when performing upgrades. Even if a system is completely secure today, one has to also consider how that system might evolve over time or work with different members.
By contrast, offline multi-signature solutions have an extremely solid record, and in the entire history of cryptocurrency exchange incidents which I've studied (listed here), there has only been one incident (796 exchange in 2015) involving an offline multi-signature wallet. It happened because the customer's bitcoin address was modified by hackers, and the amount that was stolen ($230k) was immediately covered by the exchange operators. Basically, the platform operators were tricked into sending a legitimate withdrawal request to the wrong address because hackers exploited their platform to change that address. Such an issue would not be prevented in any way by the use of a custodian, as that custodian has no oversight whatsoever to the exchange platform. It's practical for all exchange operators to test large withdrawal transactions as a general policy, regardless of what model is used, and general best practice is to diagnose and fix such an exploit as soon as it occurs.
False promises on the backing of funds played a huge role in the downfall of Quadriga, and it's been exposed over and over again (MyCoin, PlusToken, Bitsane, Bitmarket, EZBTC, IDAX). Even today, customers have extremely limited certainty on whether their funds in exchanges are actually being backed or how they're being backed. While this issue is not unique to cryptocurrency exchanges, the complexity of the technology and the lack of any regulation or standards makes problems more widespread, and there is no "central bank" to come to the rescue as in the 2008 financial crisis or during the great depression when "9,000 banks failed".
In addition to fraudulent operations, the industry is full of cases where operators have suffered breaches and not reported them. Most recently, Einstein was the largest case in Canada, where ongoing breaches and fraud were perpetrated against the platform for multiple years and nobody found out until the platform collapsed completely. While fraud and breaches suck to deal with, they suck even more when not dealt with. Lack of visibility played a role in the largest downfalls of Mt. Gox, Cryptsy, and Bitgrail. In some cases, platforms are alleged to have suffered a hack and keep operating without admitting it at all, such as CoinBene.
It surprises some to learn that a cryptographic solution has already existed since 2013, and gained widespread support in 2014 after Mt. Gox. Proof of Reserves is a full cryptographic proof that allows any customer using an exchange to have complete certainty that their crypto-assets are fully backed by the platform in real-time. This is accomplished by proving that assets exist on the blockchain, are spendable, and fully cover customer deposits. It does not prove safety of assets or backing of fiat assets.
If we didn't care about privacy at all, a platform could publish their wallet addresses, sign a partial transaction, and put the full list of customer information and balances out publicly. Customers can each check that they are on the list, that the balances are accurate, that the total adds up, and that it's backed and spendable on the blockchain. Platforms who exclude any customer take a risk because that customer can easily check and see they were excluded. So together with all customers checking, this forms a full proof of backing of all crypto assets.
However, obviously customers care about their private information being published. Therefore, a hash of the information can be provided instead. Hash is one-way encryption. The hash allows the customer to validate inclusion (by hashing their own known information), while anyone looking at the list of hashes cannot determine the private information of any other user. All other parts of the scheme remain fully intact. A model like this is in use on the exchange CoinFloor in the UK.
A Merkle tree can provide even greater privacy. Instead of a list of balances, the balances are arranged into a binary tree. A customer starts from their node, and works their way to the top of the tree. For example, they know they have 5 BTC, they plus 1 other customer hold 7 BTC, they plus 2-3 other customers hold 17 BTC, etc... until they reach the root where all the BTC are represented. Thus, there is no way to find the balances of other individual customers aside from one unidentified customer in this case.
Proposals such as this had the backing of leaders in the community including Nic Carter, Greg Maxwell, and Zak Wilcox. Substantial and significant effort started back in 2013, with massive popularity in 2014. But what became of that effort? Very little. Exchange operators continue to refuse to give visibility. Despite the fact this information can often be obtained through trivial blockchain analysis, no Canadian platform has ever provided any wallet addresses publicly. As described by the CEO of Newton "For us to implement some kind of realtime Proof of Reserves solution, which I'm not opposed to, it would have to ... Preserve our users' privacy, as well as our own. Some kind of zero-knowledge proof". Kraken describes here in more detail why they haven't implemented such a scheme. According to professor Eli Ben-Sasson, when he spoke with exchanges, none were interested in implementing Proof of Reserves.
And yet, Kraken's places their reasoning on a page called "Proof of Reserves". More recently, both BitBuy and ShakePay have released reports titled "Proof of Reserves and Security Audit". Both reports contain disclaimers against being audits. Both reports trust the customer list provided by the platform, leaving the open possibility that multiple large accounts could have been excluded from the process. Proof of Reserves is a blockchain validation where customers see the wallets on the blockchain. The report from Kraken is 5 years old, but they leave it described as though it was just done a few weeks ago. And look at what they expect customers to do for validation. When firms represent something being "Proof of Reserve" when it's not, this is like a farmer growing fruit with pesticides and selling it in a farmers market as organic produce - except that these are people's hard-earned life savings at risk here. Platforms are misrepresenting the level of visibility in place and deceiving the public by their misuse of this term. They haven't proven anything.
Fraud isn't a problem that is unique to cryptocurrency. Fraud happens all the time. Enron, WorldCom, Nortel, Bear Stearns, Wells Fargo, Moser Baer, Wirecard, Bre-X, and Nicola are just some of the cases where frauds became large enough to become a big deal (and there are so many countless others). These all happened on 100% reversible assets despite regulations being in place. In many of these cases, the problems happened due to the over-complexity of the financial instruments. For example, Enron had "complex financial statements [which] were confusing to shareholders and analysts", creating "off-balance-sheet vehicles, complex financing structures, and deals so bewildering that few people could understand them". In cryptocurrency, we are often combining complex financial products with complex technologies and verification processes. We are naïve if we think problems like this won't happen. It is awkward and uncomfortable for many people to admit that they don't know how something works. If we want "money of the people" to work, the solutions have to be simple enough that "the people" can understand them, not so confusing that financial professionals and technology experts struggle to use or understand them.
For those who question the extent to which an organization can fool their way into a security consultancy role, HB Gary should be a great example to look at. Prior to trying to out anonymous, HB Gary was being actively hired by multiple US government agencies and others in the private sector (with glowing testimonials). The published articles and hosted professional security conferences. One should also look at this list of data breaches from the past 2 years. Many of them are large corporations, government entities, and technology companies. These are the ones we know about. Undoubtedly, there are many more that we do not know about. If HB Gary hadn't been "outted" by anonymous, would we have known they were insecure? If the same breach had happened outside of the public spotlight, would it even have been reported? Or would HB Gary have just deleted the Twitter posts, brought their site back up, done a couple patches, and kept on operating as though nothing had happened?
In the case of Quadriga, the facts are clear. Despite past experience with platforms such as MapleChange in Canada and others around the world, no guidance or even the most basic of a framework was put in place by regulators. By not clarifying any sort of legal framework, regulators enabled a situation where a platform could be run by former criminal Mike Dhanini/Omar Patryn, and where funds could be held fully unchecked by one person. At the same time, the lack of regulation deterred legitimate entities from running competing platforms and Quadriga was granted a money services business license for multiple years of operation, which gave the firm the appearance of legitimacy. Regulators did little to protect Canadians despite Quadriga failing to file taxes from 2016 onward. The entire administrative team had resigned and this was public knowledge. Many people had suspicions of what was going on, including Ryan Mueller, who forwarded complaints to the authorities. These were ignored, giving Gerald Cotten the opportunity to escape without justice.
There are multiple issues with the SOC II model including the prohibitive cost (you have to find a third party accounting firm and the prices are not even listed publicly on any sites), the requirement of operating for a year (impossible for new platforms), and lack of any public visibility (SOC II are private reports that aren't shared outside the people in suits).
Securities frameworks are expensive. Sarbanes-Oxley is estimated to cost $5.1 million USD/yr for the average Fortune 500 company in the United States. Since "Fortune 500" represents the top 500 companies, that means well over $2.55 billion USD (~$3.4 billion CAD) is going to people in suits. Isn't the problem of trust and verification the exact problem that the blockchain is supposed to solve?
To use Quadriga as justification for why custodians or SOC II or other advanced schemes are needed for platforms is rather silly, when any framework or visibility at all, or even the most basic of storage policies, would have prevented the whole thing. It's just an embarrassment.
We are now seeing regulators take strong action. CoinSquare in Canada with multi-million dollar fines. BitMex from the US, criminal charges and arrests. OkEx, with full disregard of withdrawals and no communication. Who's next?
We have a unique window today where we can solve these problems, and not permanently destroy innovation with unreasonable expectations, but we need to act quickly. This is a unique historic time that will never come again.

It's of increasing importance for all users to adopt a password manager because commonly used passwords and repeated use of log-in + password combinations are the two weakest points in any normal individual's security online. Meanwhile, memorizing dozens of unique and complex passwords is beyond the scope of what most people can do, especially long term. Thus password managers have been created as a way to store multiple passwords into a single file that can help ensure your security and privacy online. For a little encouragement, we'll share the now extremely famous dialogue between Edward Snowden and John Oliver talking about passwords. As should be painfully obvious by now, password managers are one of the best solutions to this entire dilemma. https://preview.redd.it/ribbtjwz1it51.png?width=1000&format=png&auto=webp&s=3c3a9a31bdb8c4f9ec83bea98638fec5dd78b38f
PASSWORD MANAGER BASICS
We should first note that not all password managers are created the same as we've noted with software across all of our other articles. By and large, we'll be looking for similar characteristics in our password managers as we would our other software which includes open sourced software protocols and best software security practices. And when it comes to Bitcoin, cryptocurrency and your entire life's work on the internet, there is a lot at stake here. I'd argue that it is more important for password managers than for any other application to make sure to get this one correct since it will have your entire livelihood on the line. The very amazing thing with demanding open sourced software for your password manager is that it by definition will also be free at the most basic level. This is because if it weren't, all it would take would be someone to fork over a program to make it free. So you are in a sense getting the best of both worlds here; a free software that is also of the highest quality. Meanwhile, ironically, many of the more commonly known password managers like Dashlane or Lastpass use closed source software and often charge fees to use their service. Funnily enough, Lastpass, the password manager itself, was actually formerly hacked in the past. One could argue this at least in part had to do with it's closed source software since having open sourced software at least in part makes software more secure. In short, do not used these closed source services that are frequently advertised for on the web as they are detrimental to you in more ways than one.
RECOMMENDED BEST PASSWORD MANAGERS
Bitwarden is our first recommendation. Bitwarden is truly one of the all time greats by approaching password management on the individual, team and even enterprise level to create a one size fits all solution. Bitwarden is compatible on virtually all devices out there from all desktops to mobile devices and so forth. Additionally, while they offer a centralized cloud service for free, Bitwarden is also set up to allow you to run your own private server to keep your own key base entirely under your own control, fully encrypted. https://preview.redd.it/zmlkf5d12it51.jpg?width=770&format=pjpg&auto=webp&s=02998b777d05ab00557a97c616a4b0d505b324aa Next up we have KeePassXC which is a fork of one of the longest standing password managers in existence, formerly known as KeePass that halted a lot of it's ongoing development some time ago. KeePassXC was created as a locally held password manager application that could work across platforms. Unlike Bitwarden where your key file is held in cloud storage, KeePassXC is simply a program client and a local file that you must maintain and backup yourself. This has some pros and cons. The good news is that you have full control of everything related to KeePassXC as the program under most situations will not be talking to any online server which could expose private or sensitive information. The bad news is that if you ever were to lose control of your key file, you are completely out of luck. For this reason, it's imperative to back up your encrypted key file in multiple locations to protect against what would be catastrophic loss. You can do this with USB drives, e-mail accounts, cloud storage, safe deposit boxes or a whole host of other creative solutions that you might come up with. The final recommended option is LessPass. LessPass is very interesting technology because it is a no-knowledge password manager. By inputting a few pieces of information which could be a master password in conjunction with an e-mail address or user name, a password is automatically attached to any URL address. It will simply cross all of these pieces of information via PBKDF2 and SHA-256 to produce random yet consistent outputs for any of your web browsing. The advantage of this program is that it is extremely light weight, and so long as you can remember your e-mail address, account name and master password, you can now gain full access to everything around the internet without the need of any files. The downside is some level of control over password flexibility since the passwords are automatically generated for you. In summation of these three options, BitWarden is the best overall password manager for most people's use cases. Meanwhile, LessPass is probably best suited for the most casual user who contains fewer accounts across the internet and wants something extremely simple and easy to use. Lastly, KeePassXC, will be the ultimate in privacy password manager technology and is best suited for those that are prepared to take the extra steps to ensure their key file is kept up to date as the months and years tick by. https://preview.redd.it/r4icjup22it51.jpg?width=1920&format=pjpg&auto=webp&s=622cf1b967ec5622e3feb2b49e5ac29917629cdf
BEST PRACTICES WITH YOUR NEW PASSWORD MANAGER
Once you have chosen a password manager from the above list, it will be important to change all of your account passwords one by one to incorporate it into your new system. This will help you get away from your commonly used log-in and password combinations and over to your new, more secure and robust set up. With your new set up, if you have a key file to back up, you must now start getting in the habit of doing so, especially after major or important changes to your password manager. Or if you wish to use BItWarden with a private cloud server, make sure that that is fully set up and running. Generally speaking, when choosing password length from your password manager for standard and robust security, 25 random characters, letters (and symbols if you wish, but they aren't necessary), is mostly considered to be uncrackable. This is because while every password is in theory beatable, it takes dramatically more computational energy over time to figure out what your password is, and at some point, it becomes unreasonable. That said, NSA grade security often holds itself up to 50 random characters which is considered to be unbreakable even on a government wide scale. On that same token, you'll have to use a master password for your password manager. Given that you only need to know one password, it will now be extremely important to make this a very good password. Because a password that you need to remember most likely won't (or perhaps shouldn't) be completely random so that it's easy to remember, it should, at the very least, be long. I would suggest making sure that you come up with a master password that is at least 40 characters long or 125 bits of information. To check out how many bits of entropy your master password is, you can type it into the password field of KeePassXC and it will tell you roughly how secure your master password is. While 40 characters may seem like a lot, do keep in mind that this is now the only gateway between yourself and all of your access keys to all of your accounts held on this account. Bits of Entropy Example on KeePassXC Finally, it is worth investing in a YubiKey or similar 2-FA device if you can get one. This can apply to BitWarden and KeePassXC. With the normal password managers, a hacker will need access to not only your password but also your key file in order to have free reign over all of your accounts. However, a sophisticated hacker that has full access to your device with a keylogger could ultimately, in theory, compromise your full set up, and this would be disastrous for you. Fortunately, this can be resolved by buying and activating a Yubikey or other such device. The Yubikey example requires that a Yubikey, with a private key that you set up for your password manager, is present to access your database. Therefore, even if a hacker were to obtain your key file and your master password, they still won't be able gain access to your account. As a precaution, however, if you lose access to your Yubikey and/or private key, you too, will be locked out. Therefore, it is important to keep your Yubikey backed up and to keep extra copies available.
Owning Bitcoin or other cryptocurrencies comes with a lot of responsibility if you want to minimize risk. As does maintaining a strong hack-resistant presence online. One of the best defenses you can make is by implementing a password manager. Similar to the previous CryptoSmarts articles that we have written prior, it will take some small amount of set up work to get fully acclimated to your new system, but you'll thank yourself down the road that you have done this. And the sooner you start, the better, as things will only continue to get more complex, with more risk factors at play as the internet plays an ever increasing role in all of our day to day lives. Finally, while the article is current as of the writing of the article, it will undoubtedly lose merit over time. Be sure to check if everything in this article is up to date or that any password manager that you select from this article continues development or continues to abide by the proper best practice principles. If you enjoyed this article, we would encourage you to check out our other previous CryptoSmarts articles discussing private e-mails, secure messenger applications and proper web browsers.
https://soundcloud.com/user-807100315/hostinger-best-web-hosting-review Visit at- https://webhostingservice.home.blog/2019/06/02/hostinger-free/ There's no uncertainty that with regards to web hosting, Hostinger is just the least expensive choice accessible today, with costs beginning at $0.99 every month. No other organization figures out how to try and approach. A large portion of them offer a fundamental arrangement for multiple times the cost. Believing that it's unrealistic? It isn't. Yet, let me let you in on a little mystery at this moment. To get the best costs, you'll need to focus on Hostinger for quite a while. This would be a keen activity – if the administration is really extraordinary. Since your guests couldn't think less about the amount you pay for hosting. They do think about quick stacking speeds, and about really having the option to arrive at your site when they have to. They additionally need to realize that their own information will be secure and ensured. Could Hostinger offer that? I have my assessments; however I would not like to put together my audit with respect to my supposition alone. As Website Planet is accessible in various dialects, for some odd reason we have web hosting specialists dissipated everywhere on over the world. This was my brilliant chance to play out an enormous scope test, and I chose to do precisely that. We had 30 specialists join to Hostinger and dispatch a neighborhood form of our testing website in 30 distinct nations. They messed with each accessible element, observed stacking velocities and execution, and even besieged client care with questions. They contrasted the outcomes and other mainstream has, as SiteGround and InterServer. This speedy response to every one of our inquiries is that Hostinger performed strikingly well. In certain nations, similar to Russia, it came in at #4. In others, similar to Israel, Hostinger grabbed the #1 place. Peruse on for the long answer. I've point by point my full close to home involvement in Hostinger, and I'll disclose precisely how to take advantage of what the organization offers. To perceive how Hostinger looks at to different administrations, look at our rundown of the top web has. Everything an Amateur Needs With costs being as low as they may be, my restless character quickly recognized two zones where Hostinger may be attempting to pull one over on me: highlights and execution. Indeed, I'd love to pay half of what the contenders charge, yet I would prefer not to get just 50% of what they give. Fortunately, that wasn't the situation by any means, as Hostinger's arrangements incorporate all that I expected to get moving, from abundant assets to execution boosting apparatuses. Three shared hosting plans are accessible – Single, Premium, and Business. Each of the three works on head of Hostinger's own special control board, cPanel, which incorporates simple auto establishments of WordPress and many other substances the executive’s frameworks (CMS). I pursued the essential arrangement, which accompanied 10GB of plate space, 100GB of transfer speed, 1 email record, and backing for a solitary website. It's sufficient assets to construct an entirely good website – consider hundreds pages and a huge number of HD pictures. Certainly enough to grandstand your composition, innovativeness, items, administrations, or whatever you're anticipating hosting. The two progressed plans accompany boundless data transmission, boundless email accounts, and boundless websites. Some additional advantages that you won't get with the Single arrangement incorporate SSH access for you Linux-sharp designers, boundless sub domains, and boundless information bases. Programmed every day reinforcements are the one basic component that the fundamental arrangement needs, which means you'll need to perform reinforcements physically or buy the administration as a different extra. Hostinger has an intuitive website manufacturer by the name of Zyro, however it isn't accessible as a component of the hosting plans. Before we dive further into Hostinger's best highlights, a word on the VPS and cloud plans. Hostinger is above all else a mutual hosting supplier. Try not to be that person who goes to the best pizza joint around and requests pasta. There are has that represent considerable authority in VPS and cloud administrations – Fluid Web and Kinsta, for instance – and keeping in mind that Hostinger's contributions in the field aren't the most exceedingly terrible, there's no motivation to go for them. cPanel Has All the Fundamental Highlights, yet Does not have Some Serious Ones As I said previously, Hostinger has built up its own exclusive control board, which means you won't get the chance to play with the dearest cPanel that you know and love. What's that? You don't create enthusiastic connections to hosting control boards? All things considered, you're the bizarre one. At any rate, while cPanel used to be the standard control board you'd get with most has (counting Hostinger), things change. Because of some exhausting venture show that happened some time back, has have been exchanging boards left and right. cPanel is Hostinger's endeavor into the board world, and you'll see it furnished with all the treats you need. From simple auto establishments and DNS zones setups to email accounts, a record administrator, and MySQL information bases, it's all fundamentally the same as what cPanel offers. However, a few things are unique. For instance, auto establishments in cPanel are finished with Softaculous, which additionally lets you clone your site, set up an arranging variant, and even design a reinforcement plan. cPanel's Auto Installer works admirably at auto-introducing WordPress, yet does not have these valuable additional items. Progressed email highlights, such as mailing records, channels, and routings, are additionally absent from cPanel. Did I ever really use them myself when they were accessible to me? Truly, never. I don't know who does. Yet, that is cPanel for you – it probably won't be equipped for everything, except it's certainly enough for most clients. Amazing Reserving On account of the LiteSpeed Web Worker LiteSpeed isn't the physical metal worker, however the web worker innovation that Hostinger employments. It reliably positions as one of the quickest and most dependable web workers, beating the more seasoned Apache innovation that hosts like GoDaddy despite everything use. You won't need to successfully arrange it. Simply kick back and appreciate the first class execution it conveys, particularly for WordPress websites. What you can do, and assuredly ought to do, is initiate LiteSpeed's reserving capacity, known as LSCache. Sounds excessively specialized? Indeed, turning on the Programmed Store alternative basically summarizes it. Stored duplicates of your pages will be made, fundamentally slicing conveyance times to guests. Static pages, similar to business pages and portfolios, will profit by this significantly more. A SSL Declaration that you could conceivably be getting You need a SSL testament. Regardless of what you think and regardless of what anyone might've let you know – you need a SSL. Why? Since without a SSL authentication to scramble and secure your guests' information, the numerous wrongs prowling on the web will seek it. You'll not exclusively be taking a chance with your undertaking and your guests' wellbeing; however you'll additionally endure a shot on Google's rankings. Today, Hostinger furnishes a SSL with the entirety of its arrangements. In the metaphorical yesterday, which for my situation was only two or three months back, no testament was given. What will happen tomorrow is impossible to say. Hostinger regularly messes with its arrangement highlights, and I propose that you triple-check and ensure that a SSL is to be sure included with your arrangement. Realize that if a SSL is excluded, it's conceivable to buy one as a different extra. In any case, that shouldn't be the situation. All that Is All around Structured, however you’ll be under Consistent Assault from up sell Pop-Ups. Laying it out plainly, Hostinger's client experience specialists have designed an awesome interface and client venture, from information exchange to utilizing and dealing with your hosting. Thing is, Hostinger's business methodology depends on continually pushing you to overhaul and buy additional items. It's irritating, best case scenario, and confounding at the very least. Yet at the same time, the plans are unmistakably spread out, and all Hostinger requests on information exchange is your name, an email address, and a secret word. Yahoo for getting rid of all the insignificant data that different hosts are so enthused about gathering. Interfacing a Domain and Introducing WordPress In the wake of buying my arrangement, the time had come to associate a domain and introduce WordPress. I was given the choice to consequently introduce WordPress as a major aspect of the information exchange measure, however I decided to do it the normal way, utilizing the control board itself, to check how Hostinger's apparatuses contrast with what different hosts give. Presently, my domain was really included with the expectation of complimentary when I bought the Single arrangement, which means it was at that point associated with the hosting. Today, for reasons unknown, just the serious plans accompany a free domain. In the event that you wind up getting your domain name from another supplier, interfacing it is simple. Nameserver data is promptly accessible at the head of your hosting subtleties page, and you should simply duplicate glue them into your domain board. Shouldn't something be said about WordPress? I opened the Auto Installer instrument, picked WordPress as my CMS of decision, and entered the essential website subtleties. It was much easier than how Softaculous gets things done, and my new website was ready for action inside one moment. Dealing with Your Hosting with hPanel Is Simple We've secured the way toward getting your website on the web, however starting here on you'll despite everything use cPanel to make alters and changes to your hosting. Setting up an email account, running manual reinforcements, dealing with the information bases, and the sky is the limit from there, are largely possible through cPanel. How can everything contrast with getting things done with cPanel? Indeed, as I would like to think, it's out and out simpler. hPanel symbols are greater and better sorted out, the interface isn't as jumbled with additional alternatives that you'll never utilize, and the combination with Hostinger's different administrations (uphold, buying additional items, seeing charging) is consistent. All in all, would we be able to consider it an ideal usability experience? Actually no, not so much. The explanation, as I said previously, is that periodically your work process will be harmed by up sell pop-ups. Think rolling out a basic improvement to your DNS records, just to be welcomed with this: I didn't "Increase present expectations." I didn't really do anything aside from sign in. Yet, Hostinger is enthusiastic about pushing plan redesigns, and you'll need to consistently be set up to close down these endeavors, of which there are many. Don't count on the possibility that these pop-ups imply that you've by one way or another spent your assets and need to redesign. Pass on, It's the Quickest Common Hosting Administration We Tried Speed and uptime that is what I'm searching for. Tragically, shared hosting administrations will in general vacillate in these regions, no doubt. The explanation is that as the name infers, you're offering assets to numerous different clients and their websites – in some cases up to many others. It takes an extraordinary host to adjust everything and stay away from a bottleneck circumstance where everything's moderate and no one's cheerful. I'm extremely glad to report that Hostinger exceeded expectations in the presentation tests, yet it really surpassed each other shared host that we tried, including the top-level SiteGround, FastComet, and InMotion Hosting. The main two has that improved, and just barely, were the superior Fluid Web (Nexcess) and Kinsta. Incidentally, they can cost around 20 fold the amount of as Hostinger. Just to give you a thought of Hostinger's capacities, the normal stacking season of my completely fledged greeting page was an exceptional 1.56s, and uptime over a couple of long stretches of testing was as much as 99.99%, precisely as guaranteed. I'm going to nerd out and clarify the testing technique and the outcomes in detail, yet on the off chance that you needn't bother with all the specialized data, don't hesitate to avoid ahead to my encounters with Hostinger's help. I'll simply say it again – Hostinger's presentation shook. As I do with all hosts I test, I stretched out Hostinger the chance to streamline my website and make it quicker. This is something you can (and should) do too – simply approach uphold for help. The operator prompted that I update WordPress and PHP to their most recent forms, and introduce a couple of regular enhancement modules. I actualized the exhortation, and continued with testing. The testing itself was finished utilizing three apparatuses: GTmetrix Genius, the Sucuri Burden Time Analyzer, and Uptime Robot's Professional arrangement. The Dallas, TX, GTmetrix worker was utilized to quantify speed and advancement scores in the US. Sucuri was utilized for worldwide execution experiences, and Uptime Robot – who could have imagined – for following the website's uptime and accessibility online in rates. GTmetrix I ran various GTmetrix tests over a couple of months, totaled the outcomes, and determined the best, slowest, and normal paces. Hostinger indicated a promising normal stacking season of 1.56s. The best recorded time was 1.0s, and the slowest one was 1.9s. Not exclusively is the slowest stacking time well underneath the 3s imprint (where the majority of your guests will likely escape), however the normal scores demonstrate that Hostinger is as solid as anyone might imagine. You can see that score-wise, we're getting twofold Bs. That is totally satisfactory, yet in addition probably the most noteworthy score I found in my tests. The main thing left to do so as to get full scores is to improve the pictures further. Sucuri Burden Time Analyzer As with GTmetrix, I ran Sucuri tests on numerous occasions. Sucuri gives you the stacking speed results for some worldwide areas, and I determined the midpoints of the quickest area (which was obviously in the US, near my server farm), the slowest area (Bangalore, India – the opposite side of the world), and the worldwide normal. The normal for the quickest area was an incredible 0.177s, while even in old fashioned Bangalore the normal was good – 1.11s. The worldwide normal was 0.499s, which earned my website an A worldwide position. Frankly? I was shocked by these numbers. A worldwide normal of 0.499s is unfathomable for a common host, and everything I did to "streamline" my site was introduce a couple modules. There wasn't so much as a CDN (Content Conveyance System) dynamic. That is LiteSpeed and LSCache for you, women and respectable men. Get it while it's hot. Uptime Robot What great are quick speeds if your website has low accessibility? Nothing but bad. Fortunately, Hostinger is keeping it tight with practically immaculate uptime – 99.997% in the course of recent months. I'm proceeding to track and update the outcomes; however coming barely short of 100% is actually what I request from my host. Uptime ensure shrewd, the circumstance is somewhat extraordinary. There's apparently a 99.99% uptime ensure gave, yet Hostinger has a genuine scrappy lawful clarification of when and how you can get your cash back. It generally seems like "never" to me, and regardless of whether you some way or another fit the bill for a cash back (as exclusively dictated by them), it's a measly 5% of your month to month cost. Goodness, and it's only for store credit. In any case, beside this assurance issue, Hostinger truly blows it out of the recreation center in the exhibition test. When Extraordinary, Presently… Requires Tolerance As a long-term client of Hostinger, I've had the delight of testing it over and over… and once more. One of my preferred pieces of the administration used to be the help. There wasn't (and still isn't) any telephone uphold accessible, yet stunning, was live talk a successful method of finding support. Day in and day out help, kept an eye on by experts, and supported by a broad information base of immense extents. The main issue? While the operators used to react in a flash, today they take around 40 minutes to hit you up. In some cases live talk isn't even accessible, and you're moved to some ticket/email framework which I've had next to no karma with. I'll be totally fair with you about what this implies: it will be you and the information base. You can't rely on having an hour accessible to just stick around, and in any event, when the operators do reply, that is only the start of the cycle. With 3 brief reaction times in the middle of messages, posing some straightforward inquiries can expand into a whole workday. The Least expensive Long haul Costs Available, by a wide margin Truly, people, this is the explanation you understand this. While going over the many hosting choices accessible today, Hostinger's costs stick out. That is to say, $0.99 every month? That is excessively modest. What's the trick? Straightforward. Hostinger needs you to pursue a significant stretch of time, and it will give you motivating forces to do as such. Four installment periods are accessible: month to month, yearly, bi-yearly, and quadrennial. That final word implies four years, and it's scarcely utilized in light of the fact that practically no other host approaches you to pursue that long. Fortunately pursuing four years will net you what's without a doubt the best cost in the market for shared hosting. Different hosts charge a comparable cost for a yearly arrangement. Crunch the numbers yourself. What's the circumstance when pursuing shorter periods? All things considered, bi-yearly and yearly plans aren't costly, yet they're significantly more in accordance with the market normal. Month to month plans accompany an arrangement expense and don't bode well. Worth insightful, up to a SSL is incorporated (check!), the plans are totally comparable to the business standard. There's additionally a 30-day unconditional promise, so you'll have adequate opportunity to test the administration yourself and check whether it's a solid match. One thing to see during the checkout cycle is that there are a couple of discretionary extra administrations. Fortunately, none of them come pre-checked. I suggest that you skip them all. You can generally include them later at a similar cost, or "convince" a help operator to give you a superior arrangement… dangers of leaving the administration can do something amazing here. Searching for a free domain? Now and again it's remembered for the plans; some of the time it isn't. The serious plans normally accompany one when pursuing a year or more. At the point when I joined, a domain was additionally remembered for the fundamental arrangement. Presently it isn't – go figure. Concerning making installments, notwithstanding the normal charge card and PayPal choices, you'll additionally have the option to pay with bitcoin and different cryptographic forms of money. Whatever your reasons are for needing to have a website secretly, crypto is the best approach to do as such. Hostinger's reasonable shared hosting plans merit your time, your cash, and your thought. Execution has been shockingly extraordinary, and keeping in mind that it's not the most element pressed contribution around, it has all that you truly need. Would it be advisable for you to put it all on the line? In case you're constructing a blog, a business page, an individual task, or a comparative little to-medium website, my answer is a resonating yes. In the event that it's a web based business store you're hoping to fabricate, or a mind boggling administration like an online course gateway, you'll need something more remarkable than shared hosting. It'll cost you, yet Fluid Web and Kinsta are both better prepared for such ventures.
It has been shared on multiple subreddits so I have no idea where to even post this. But I'd like to come up with a follow-up thread with some more information. The internet is the most powerful tool that mankind has ever invented. You have the ability to reach thousands, millions and even billions of people with just a computer and some internet access.
If you're on this subreddit, chances are you're already playing Tibia and you already have a computer and internet access. It doesn't need to be the best internet, but as long as websites will load (eventually) you are good to go.
In this topic I will go more in-depth on web development and software engineering. If you have a very slow internet connection, you may want to look into web development instead of software development. An application/software is much heavier (larger file size) than a website. And most developer jobs require that you send and download files, back and forth, between you and your company's server. So if you feel like your internet is too slow to send a lot of files - do not worry! There are plenty of jobs.
First, I will go through some more details on how to learn web development and software development. After that, I will list a few other kinds of jobs that you can do remotely. These types of jobs can be done from anywhere in the world as long as you have internet access.
Part 1: Some languages you should learn
What is web development? Well, it can be a lot of things. You perhaps make websites for shops/restaurants/hair dressers/dentists, or you work for a big company and work on their web application, like Outlook, Discord or Spotify (which can all be accessed via a browser: their web app). You can also work with design and user experience, instead of programming. Being a web developer can mean so many different things, it's impossible to name them all. But most web developers are just developers: they program. They make websites, and they either sell the websites to companies (as a consultant) or you work full/part-time for a company.
I can not provide in-depth information about every single thing, but I can give you some pointers. The very basics any web developer should know is this:
HTML (HyperText Markup Language) - it's what almost all websites use as a foundation. This is not a programming language, but it is a markup language. If you want to build websites, you pretty much have to know this language. Don't worry though, it is easy. Not so much to learn. You can learn all about it in a few weeks.
CSS (Cascading Style Sheets) - it's what will add colors and shapes to your website. If you want to focus more on design (also known as front end development) then this is where you want to gain a lot of knowledge.
Python - A very simple language to learn. This language is very often the first programming language that developers start using. You can use it for a lot of things. This language is used in the back of a lot of websites. Google has been using Python for years and still is. It's great for web scraping and making web requests. If you want a language to practice your algorithms, then this language is awesome.
PHP - This used to be a very popular language, but not so much these days. However, it is very good to know how this works because it's very simple to learn and also very functional in some cases. If you want to transmit or withdraw information from a database to your website, then this (in combination with SQL) is a great way to do so. Whenever you make a login system or a contact form, the data must be sent somehow to a recipient or a database. PHP will help you do that. It is a server-side language, which means it will run in the back of the website.
SQL - To be able to communicate with databases (for example: save data, update data, or insert data) you can use different languages for that. But SQL is probably the most widely used language for this. It is basically just a bunch of commands that you tell your website or app to do. If you have a web shop for example, you will need a database to store all your product information in. You can for example use MySQL as your database and then use the SQL language to extract data from your database and publish it as a list of products on your website.
Java - This is pretty much 90% identical to C# as I wrote above. Widely used, relatively easy to learn the basics and there's plenty of jobs. If you like making android apps, this language is for you.
Part 2: Technologies and useful tools
To become a web developer you will need a few tools. You need a text editor, a FTP client, a SSH client and some other things. Also a good browser.
Text editor: Visual Studio Code, Atom, Sublime Text, Brackets - There are many different text editors but at the moment, I highly recommend Visual Studio Code. It has so many built-in features it's honestly the only thing you may need.Don't forget to install Notepad++ as well - this very basic editor is so handy when you just quickly need to edit some files.
File archiving: WinRar, 7-Zip - You need some way of archiving projects and send it to your customer or employer. These are basic tools anyone should use. I personally use Winrar.
FTP (File Transfer Protocol): FileZilla - This tool will allow you to connect to your website's file manager and upload your files to it. There are many tools for connecting to an FTP server but this is the most popular one, it's simple and it works great.
VPS (Virtual Private Server): Amazon Web Services, Google Cloud - If you want to practice building web applications or want to host your own website as a fun project, it's great to use a VPS for that. Both Amazon and Google offers 365 days of free VPS usage. All you need is a credit card. However, they will not charge you, as long as you stay below the free tier limit. A VPS is basically a remote computer that you can connect to. I highly recommend that, if you have a slow internet connection. Those VPS-servers (by Amazon and Google) usually have 500mbit/s internet speed, which is faster than most countries in the world. You simply connect to them via Remote Desktop, or by SSH. Depending on what type of server you are using (Windows or Linux).
SSH (Secure Shell): Solar-PuTTY, PuTTY - If you for example have a web server where you store applications and files, a great way to connect to it is by using SSH. PuTTY is pretty much the standard when it comes to SSH clients. But I really love the version created by SolarWinds. When you download that one, do not enter your personal details. Their sales people will call you and haunt you! Haha.
File Searching: Agent Ransack - When you have many files and try to locate a specific document or file, you may want to use something like Agent Ransack. Much faster than the traditional search feature in Windows and it is much more accurate.
IDE / Code Editor: Visual Studio - Great tool to use when you want to create applications in C# for example. Do not confuse this with Visual Studio Code. These are two very different tools. This tool (Visual Studio) is more designed for Windows applications. Not just websites. I only recommend getting it if you plan to make programs for Windows.
Web host & domain: NameCheap, Epik, SiteGround - If you develop websites on your own, or maybe want to create a portfolio website, you will need a domain name and web hosting. I have personally used all of these 3 and they are very cheap. NameCheap has some of the cheapest domains and great web hosting for a low price. Their support is also great. Same with SiteGround. And if you want to buy a domain anonymously (with Bitcoin for example), then you can use Epik. Low prices and great customer service on all these 3 websites.
Web Browser: Mozilla Firefox, Microsoft Edge Insider, Google Chrome - You need one of the latest web browsers to create websites these days. Since I prefer privacy over functionality, I've always loved Firefox. But recently, Microsoft has been improving its new version of Edge a lot (based on Chromium) and it's also very popular. If you want all your personal details to be saved and have good tools for web development, then use Google Chrome. Don't forget to utilize the built-in developer tools. You can access it in any of these browsers by pressing F12.
Other things you may want to look into:
Web services, SSL certificates, Search Engine Optimization, Databases, API, Algorithms, Data Structures
If you want to learn in-depth about algorithms, data structures and more. Then you can take a look at the curriculum of the top-tier universities of USA. Such as: UC Berkeley, Harvard and MIT. These courses are very hard and are specifically for people who want to become experts in software engineering. You can enroll some of them for free, like the one on Harvard. And by having a such diploma (which costs $90 extra) can get you a lot of job opportunities. You can enroll those courses if you want, but it can have a fee. But just take a look at what they are studying and try do their exercises, that is 100% free. Get the knowledge. It's mostly on video too! These course below are the very same courses that many of the engineers at Facebook, Google, Amazon, Apple, Netflix, Uber, AirBnb, Twitter, LinkedIn, Microsoft, etc. has taken. It's what majority of people in Silicon Valley studied. And it's among the best classes that you can take. These course are held by some of the world's best professors in IT.

Public CodeValley/Emergent Consensus questioning and investigation Thread. Ask your hard questions and dispel your doubts here.
What is going on here? I am asking some hard questions for the CodeValley Company, which recently proposed a new revolutionary software development paradigm called Emergent Coding at the latest big Bitcoin Cash conference in Australia. I am asking these questions because, as I (and ~150 people who agreed with me) noticed, there are stunning similarities between CodeValley and the companies who have tried and succeeded in crippling Peer-To-Peer Electronic Cash: nChain and Blockstream. According to me, as it looks now, similarities between these 3 companies (nChain, Blockstream, CodeValley) are the following: }- Sources of funding are extremely unclear or openly hostile to Bitcoin }- At first and even second glance, there is no product, no way to make money }- Whitepaper & Documentation is missing, hollow or total abstract bullshit, company has no logical sense of existence }- Detailed specifications or proofs of operation are not available }- Main products are closed-source patented blobs (BSV, Liquid, Emergent Coding) }- They have huge influences in the industry or try to establish themselves in such position to have the infuences I am here (and you are here, I assume) because we want to find out the truth, whatever the truth is. The point of this topic is to ask the hardest possible questions in order to estimate the probability of CodeValley company being legit. But this is also a chance for CodeValley to clear their name by providing sufficient information that proves that (after 4 years of having working company and 10+ years of having patents [Archived]) they actually have a working product and are a legit company, and not an infiltrator designed and paid by banks/TPTB in order to cripple and destroy Bitcoin Cash. Also if they truly are what they claim and they truly have such a revolutionary technology, this is a great opportunity for promotion. To show the world that the tech actually works. I will ask my questions and you can ask your questions as well. Don't make them easy. Don't have mercy (but these things work better when you are polite). Let's begin the trial by fire! Calling nlovisa My Questions/Tasks for CodeValley: [Of course you actually don't have to answer any of them or you can give us bullshit answers again, but in such case the community may conclude that you actually are next nChain/Blockstream and an enemy infiltrator, reject you and shoot down all your efforts. So the choice is yours] @@@@ 1. Please upload your actual businessplan which you presented to the people in power who gave you funding(VCs? Government?) to create $50 Million BCH tech park. A businessplan which is supposed to explain spending of $50 million AUD should have at least 7 pages (but more probably 20+). Some names and unimportant details (but NOT money/financial numbers) can be redacted. -- You have 6 hours to complete this task -- @@@@ 2. Please list your current VCs and >%5 shareholders, with CEO names and HQ locations of each of them. -- You have 4 hours to complete this task -- @@@@ 3. Few days ago you promised to upload freely-accessible documentation to https://codevalley.com/docs subpage which would describe emergent coding in greater details. @ - What happened to that promise? @@@@ 4. After I accused that your company is bullshit and your product is hollow, you immediately started to praise me and offered me a trip to Australia [Archived]. @ - So, do you always praise and offer a paid trip across the world to Australia to all people on the Internet who heavily criticize you? Is this a common practice in your company? @@@@ 5. A travel from Poland to Australia and back would cost something under $2000 AUD, counting buses, with hotels that would make something close to $2500 AUD even for few days. Based on this, I estimate your "invite random people from the internet to Australia in order to show them the product" budget has to consist of at least $50.000 AUD yearly (but $100.000 - $200.000 is more probable of course). @ A) In your financial books, what exactly is called the Excel position of your budget expenses under which would your secretary put my trip's expenses? @ B) How do you maintain such a large budget for such frivolous spending and how do you explain it to your shareholders/VCs? @@@@ 6. Few days ago you answered somebody a question: "The trust model is also different. The bulk of the testing happens before the project is designed not after. Emergent Coding produces a binary with very high integrity and arguably far more testing is done in emergent coding than in incumbent methods you are used to.". @ A) Who EXACTLY does the testing? People? Software? AI? Non-bullshit answer, please. @ B) Why exactly is there "more testing" in Emergent Coding than in normal software creation paradigm? Why is emergent coding different? Do the developers who work in this paradigm are somehow special? Are the programming languages magical? @ C) What are the specific software tools used for this "testing"? "Agents" is a non-answer, so don't even try. @@@@ 7. Please provide a simple demo binary of a simple program created completely using your "Emergent Coding" and also provide all the binary sub-component files that make up the final binary. Requirements: There has to be a minimum of 3 sub - binaries making up the final big binary for this to be valid. 2 or less does not count. None of the binaries can be obfuscated, they have to be clean X86/X86_64 machine code binaries. Notes: It should be incredibily simple, quick and easy task for you, since designing such a complex and apparently breakthough system must have required thousands, tens of thousands if not hundereds of thousands tests. All of these tests produced working binaries - after all you wouldn't claim you have a working marvellous revolutionary product without extensive testing, right? -- You have 18 hours for this task -- Of course, If you are saying the truth and have truly developed this revolutionary "emergent coding" binary-on-the-fly-merging technology, this should normally take you under 18 minutes to just find the test samples and upload them. @@@@ 8. Please construct a simple (binary or source) single-use-compiler demo that will combine 3 or more sub-binaries into final working product. Please upload the sub-binaries and the "single-use compiler" to publicly available site so people in our community can verify that your product is actually working. The single-use-compiler binary can be obfuscated with proper tool in order to hide your precious intellectual property. The 3 sample sub-binaries cannot be obfuscated. They have to be pure, clean, binary X86/X86_64 machine code. Everything has to be working and verifable of course. -- You have 72 hours to complete this task -- I understand all your technologies are patented with patents that basically predate Bitcoin and you are giving us obfuscated binaries, so you don't have to worry about anybody stealing your company's intellectual property, right? @@@@ 9. You mentioned the only application I need to create programs using Emergent Coding is the pilot app. @ - What programming language(s) is the pilot app written in? @@@@ 10. When you developed the Emerging Coding, before it started existing, you couldn't have used emergent coding to create the first (test & development) applications because it is a chicken and egg problem. @ - What programming language did you use to create first client/serveapi/daemon/tool used to merge multiple binaries into one in Emergent Coding? @@@@ 11. Please list all of your current programmers and programming language each of them is using next to their name. Also provide LinkedIn profiles if applicable. -- You have 18 hours to complete this task -- @@@@ 12. Please also list all Development Environments (IDEs) used by your current programmers next to their name. -- You have 18 hours to complete this task -- @@@@ 13. Please list all compilers used by your current programmers next to their name. -- You have 18 hours to complete this task -- @@@@ 14. So if I understand correctly CodeValley will be the company who runs $50 million BCH tech park and the tech will house multiple Bitcoin Cash-related startup and companies. Let's say I have a BCH startup and I would like to rent a loft/spot in your "tech park". A) Please provide a PDF of sample basic contract you have (hopefully) prepared for such startups. -- You have 4 hours to complete this task -- B) How much does the rent cost per a room (or m2/sqft) for a month and for a year? @@@@ 15. Please submit the list of compilers that produce X86/X86_64/ARM binaries compatibile with Emergent Coding "mash-it-together" "binary compiler". -- You have 4 hours to complete this task -- @@@@ 16. Is it possible for Emergent Coding to merge multiple non-binary applications (like Python or PHP programs) together? Or is it just binaries? Who are you? I am a freedom thinker and individual independent from all infuences who just does what he finds appropriate at the moment. Disclaimer to preempt questions: }- I do not work for anybody }- I do not have any hidden agenda }- I am only doing what I think is right }- I am a born revolutionist, this is why I am in Bitcoin Why are you doing this? }- Because I believe in truth above all. Truth will save us. }- Because I believe in Satoshi's peer-to-peer cash for the world vision and I will not stray from this path. }- Because most people are apparently missing psychological immune system which is why attempts like Blockstream, nChain appear and are repetedly [at least partially] successful. I have an anti-bullshit immune system that works great against this type of attacks. I was actually one of the first to be banned in /Bitcoin sub for pointing out their lies with manipulations and to spot Craig Wright's attempt to infiltrate and bend /btc sub to his will.. }- Because I was fooled twice by entities similar to CodeValley before (namingly nChain and Blockstream) and I will not be fooled again. Bitcoin Cash will not be co-opted easily as long as I am here. }- Because if Bitcoin Cash community is an organism, then I became a B lymphocyte cell. I produce antibodies. I show you how to defend yourself from bullshit, lies and manipulation. This is my basic function. }- Because I am here to kill the bank
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
