Bob The Magic Custodian



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:

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:
See - all problems are solved! All we have to worry about now is:
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:
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:
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.

Bitcoin Hacks & basic ways to protect your Crypto

Interest in Bitcoin is increasing globally. More and more people are willing to participate in Bitcoin trading and mining. However, Bitcoin history shows that it is not always as safe as we would like it to be. Let’s take a look at some major Bitcoin hacks.

Allinvain

Allinvain is a nickname of a user on BitcoinTalk forums. Basically, he was the first one to experience a major Bitcoin loss. He lost 25,000 bitcoins, all together it was worth around $500,000. The user believed that someone hacked into his computer to steal BTC.

Mt Gox

Shortly after Allinvain’s case, the next hack attempt happened. Mt Gox was one of the biggest exchanges that provided a trade between Bitcoin and fiat money. Hackers compromised its website and started to sell Bitcoins. Their actions made the price go down dramatically. However, attackers did not pay attention to the $1000 limit Mt Gox had. Nonetheless, that hack attack had an important influence on BTC.

Other exchanges

Exchanges are being attacked by hackers quite often.
In 2012 Bitfloor suffered a terrible attack and lost 24,000 BTC (around $250,000). Unfortunately, this exchange was not able to survive the attack and was closed in 2013.
In 2015 Bitstamp exchange was hacked. It lost approximately 19,000 BTC (around $5 million).
In 2016 Bitfinex also lost 120,000 BTC (around $77 million) to hackers.

Twitter hack

The last attack happened in one of the biggest social nets. Twitter became a part of the latest attackers’ actions. The most significant and world-famous accounts promoted Bitcoin scam for several hours.

Anti-hack protection

The most important question is how to protect your Bitcoin savings from upcoming attacks. Here are some basic things that may help you to be safe:
Even though there is no way to be a hundred percent safe, there are a lot of steps we can take to avoid unfortunate losses. Cryptocurrency services are improving their protection systems all the time, and we all should do what we can to make this network more secure.

How To End The Cryptocurrency Exchange "Wild West" Without Crippling Innovation


In case you haven't noticed the consultation paper, staff notice, and report on Quadriga, regulators are now clamping down on Canadian cryptocurrency exchanges. The OSC and other regulatory bodies are still interested in industry feedback. They have not put forward any official regulation yet. Below are some ideas/insights and a proposed framework.



Many of you have limited time to read the full proposal, so here are the highlights:

Offline Multi-Signature

Effective standards to prevent both internal and external theft. Exchange operators are trained and certified, and have a legal responsibility to users.

Regular Transparent Audits

Provides visibility to Canadians that their funds are fully backed on the exchange, while protecting privacy and sensitive platform information.

Insurance Requirements

Establishment of basic insurance standards/strategy, to expand over time. Removing risk to exchange users of any hot wallet theft.


Background and Justifications


Cold Storage Custody/Management
After reviewing close to 100 cases, all thefts tend to break down into more or less the same set of problems:
• Funds stored online or in a smart contract,
• Access controlled by one person or one system,
• 51% attacks (rare),
• Funds sent to the wrong address (also rare), or
• Some combination of the above.
For the first two cases, practical solutions exist and are widely implemented on exchanges already. Offline multi-signature solutions are already industry standard. No cases studied found an external theft or exit scam involving an offline multi-signature wallet implementation. Security can be further improved through minimum numbers of signatories, background checks, providing autonomy and legal protections to each signatory, establishing best practices, and a training/certification program.
The last two transaction risks occur more rarely, and have never resulted in a loss affecting the actual users of the exchange. In all cases to date where operators made the mistake, they've been fully covered by the exchange platforms.
• 51% attacks generally only occur on blockchains with less security. The most prominent cases have been Bitcoin Gold and Ethereum Classic. The simple solution is to enforce deposit limits and block delays such that a 51% attack is not cost-effective.
• The risk of transactions to incorrect addresses can be eliminated by a simple test transaction policy on large transactions. By sending a small amount of funds prior to any large withdrawals/transfers as a standard practice, the accuracy of the wallet address can be validated.
The proposal covers all loss cases and goes beyond, while avoiding significant additional costs, risks, and limitations which may be associated with other frameworks like SOC II.

On The Subject of Third Party Custodians
Many Canadian platforms are currently experimenting with third party custody. From the standpoint of the exchange operator, they can liberate themselves from some responsibility of custody, passing that off to someone else. For regulators, it puts crypto in similar categorization to oil, gold, and other commodities, with some common standards. Platform users would likely feel greater confidence if the custodian was a brand they recognized. If the custodian was knowledgeable and had a decent team that employed multi-sig, they could keep assets safe from internal theft. With the right protections in place, this could be a great solution for many exchanges, particularly those that lack the relevant experience or human resources for their own custody systems.
However, this system is vulnerable to anyone able to impersonate the exchange operators. You may have a situation where different employees who don't know each other that well are interacting between different companies (both the custodian and all their customers which presumably isn't just one exchange). A case study of what can go wrong in this type of environment might be Bitpay, where the CEO was tricked out of 5000 bitcoins over 3 separate payments by a series of emails sent legitimately from a breached computer of another company CEO. It's also still vulnerable to the platform being compromised, as in the really large $70M Bitfinex hack, where the third party Bitgo held one key in a multi-sig wallet. The hacker simply authorized the withdrawal using the same credentials as Bitfinex (requesting Bitgo to sign multiple withdrawal transactions). This succeeded even with the use of multi-sig and two heavily security-focused companies, due to the lack of human oversight (basically, hot wallet). Of course, you can learn from these cases and improve the security, but so can hackers improve their deception and at the end of the day, both of these would have been stopped by the much simpler solution of a qualified team who knew each other and employed multi-sig with properly protected keys. It's pretty hard to beat a human being who knows the business and the typical customer behaviour (or even knows their customers personally) at spotting fraud, and the proposed multi-sig means any hacker has to get through the scrutiny of 3 (or more) separate people, all of whom would have proper training including historical case studies.
There are strong arguments both for and against using use of third party custodians. The proposal sets mandatory minimum custody standards would apply regardless if the cold wallet signatories are exchange operators, independent custodians, or a mix of both.

On The Subject Of Insurance
ShakePay has taken the first steps into this new realm (congratulations). There is no question that crypto users could be better protected by the right insurance policies, and it certainly feels better to transact with insured platforms. The steps required to obtain insurance generally place attention in valuable security areas, and in this case included a review from CipherTrace. One of the key solutions in traditional finance comes from insurance from entities such as the CDIC.
However, historically, there wasn't found any actual insurance payout to any cryptocurrency exchange, and there are notable cases where insurance has not paid. With Bitpay, for example, the insurance agent refused because the issue happened to the third party CEO's computer instead of anything to do with Bitpay itself. With the Youbit exchange in South Korea, their insurance claim was denied, and the exchange ultimately ended up instead going bankrupt with all user's funds lost. To quote Matt Johnson in the original Lloyd's article: “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.”
ShakePay's insurance was only reported to cover their cold storage, and “physical theft of the media where the private keys are held”. Physical theft has never, in the history of cryptocurrency exchange cases reviewed, been reported as the cause of loss. From the limited information of the article, ShakePay made it clear their funds are in the hands of a single US custodian, and at least part of their security strategy is to "decline[] to confirm the custodian’s name on the record". While this prevents scrutiny of the custodian, it's pretty silly to speculate that a reasonably competent hacking group couldn't determine who the custodian is. A far more common infiltration strategy historically would be social engineering, which has succeeded repeatedly. A hacker could trick their way into ShakePay's systems and request a fraudulent withdrawal, impersonate ShakePay and request the custodian to move funds, or socially engineer their way into the custodian to initiate the withdrawal of multiple accounts (a payout much larger than ShakePay) exploiting the standard procedures (for example, fraudulently initiating or override the wallet addresses of a real transfer). In each case, nothing was physically stolen and the loss is therefore not covered by insurance.
In order for any insurance to be effective, clear policies have to be established about what needs to be covered. Anything short of that gives Canadians false confidence that they are protected when they aren't in any meaningful way. At this time, the third party insurance market does not appear to provide adequate options or coverage, and effort is necessary to standardize custody standards, which is a likely first step in ultimately setting up an insurance framework.
A better solution compared to third party insurance providers might be for Canadian exchange operators to create their own collective insurance fund, or a specific federal organization similar to the CDIC. Such an organization would have a greater interest or obligation in paying out actual cases, and that would be it's purpose rather than maximizing it's own profit. This would be similar to the SAFU which Binance has launched, except it would cover multiple exchanges. There is little question whether the SAFU would pay out given a breach of Binance, and a similar argument could be made for a insurance fund managed by a collective of exchange operators or a government organization. While a third party insurance provider has the strong market incentive to provide the absolute minimum coverage and no market incentive to payout, an entity managed by exchange operators would have incentive to protect the reputation of exchange operators/the industry, and the government should have the interest of protecting Canadians.

On The Subject of Fractional Reserve
There is a long history of fractional reserve failures, from the first banks in ancient times, through the great depression (where hundreds of fractional reserve banks failed), right through to the 2008 banking collapse referenced in the first bitcoin block. The fractional reserve system allows banks to multiply the money supply far beyond the actual cash (or other assets) in existence, backed only by a system of debt obligations of others. Safely supporting a fractional reserve system is a topic of far greater complexity than can be addressed by a simple policy, and when it comes to cryptocurrency, there is presently no entity reasonably able to bail anyone out in the event of failure. Therefore, this framework is addressed around entities that aim to maintain 100% backing of funds.
There may be some firms that desire but have failed to maintain 100% backing. In this case, there are multiple solutions, including outside investment, merging with other exchanges, or enforcing a gradual restoration plan. All of these solutions are typically far better than shutting down the exchange, and there are multiple cases where they've been used successfully in the past.

Proof of Reserves/Transparency/Accountability
Canadians need to have visibility into the backing on an ongoing basis.
The best solution for crypto-assets is a Proof of Reserve. Such ideas go back all the way to 2013, before even Mt. Gox. However, no Canadian exchange has yet implemented such a system, and only a few international exchanges (CoinFloor in the UK being an example) have. Many firms like Kraken, BitBuy, and now ShakePay use the Proof of Reserve term to refer to lesser proofs which do not actually cryptographically prove the full backing of all user assets on the blockchain. In order for a Proof of Reserve to be effective, it must actually be a complete proof, and it needs to be understood by the public that is expected to use it. Many firms have expressed reservations about the level of transparency required in a complete Proof of Reserve (for example Kraken here). While a complete Proof of Reserves should be encouraged, and there are some solutions in the works (ie TxQuick), this is unlikely to be suitable universally for all exchange operators and users.
Given the limitations, and that firms also manage fiat assets, a more traditional audit process makes more sense. Some Canadian exchanges (CoinSquare, CoinBerry) have already subjected themselves to annual audits. However, these results are not presently shared publicly, and there is no guarantee over the process including all user assets or the integrity and independence of the auditor. The auditor has been typically not known, and in some cases, the identity of the auditor is protected by a NDA. Only in one case (BitBuy) was an actual report generated and publicly shared. There has been no attempt made to validate that user accounts provided during these audits have been complete or accurate. A fraudulent fractional exchange, or one which had suffered a breach they were unwilling to publicly accept (see CoinBene), could easily maintain a second set of books for auditors or simply exclude key accounts to pass an individual audit.
The proposed solution would see a reporting standard which includes at a minimum - percentage of backing for each asset relative to account balances and the nature of how those assets are stored, with ownership proven by the auditor. The auditor would also publicly provide a "hash list", which they independently generate from the accounts provided by the exchange. Every exchange user can then check their information against this public "hash list". A hash is a one-way form of encryption, which fully protects the private information, yet allows anyone who knows that information already to validate that it was included. Less experienced users can take advantage of public tools to calculate the hash from their information (provided by the exchange), and thus have certainty that the auditor received their full balance information. Easy instructions can be provided.
Auditors should be impartial, their identities and process public, and they should be rotated so that the same auditor is never used twice in a row. Balancing the cost of auditing against the needs for regular updates, a 6 month cycle likely makes the most sense.

Hot Wallet Management
The best solution for hot wallets is not to use them. CoinBerry reportedly uses multi-sig on all withdrawals, and Bitmex is an international example known for their structure devoid of hot wallets.
However, many platforms and customers desire fast withdrawal processes, and human validation has a cost of time and delay in this process.
A model of self-insurance or separate funds for hot wallets may be used in these cases. Under this model, a platform still has 100% of their client balance in cold storage and holds additional funds in hot wallets for quick withdrawal. Thus, the risk of those hot wallets is 100% on exchange operators and not affecting the exchange users. Since most platforms typically only have 1%-5% in hot wallets at any given time, it shouldn't be unreasonable to build/maintain these additional reserves over time using exchange fees or additional investment. Larger withdrawals would still be handled at regular intervals from the cold storage.
Hot wallet risks have historically posed a large risk and there is no established standard to guarantee secure hot wallets. When the government of South Korea dispatched security inspections to multiple exchanges, the results were still that 3 of them got hacked after the inspections. If standards develop such that an organization in the market is willing to insure the hot wallets, this could provide an acceptable alternative. Another option may be for multiple exchange operators to pool funds aside for a hot wallet insurance fund. Comprehensive coverage standards must be established and maintained for all hot wallet balances to make sure Canadians are adequately protected.

Current Draft Proposal

(1) Proper multi-signature cold wallet storage.
(a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet.
(b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time).
(c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.
(d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds.
(e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers.
(2) Regular and transparent solvency audits.
(a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row.
(b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored.
(c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process.
(d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify.
(e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible.
(3) Protections for hot wallets and transactions.
(a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets.
(b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy.
(c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage.
(d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange.
(e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.

Steps Forward

Continued review of existing OSC feedback is still underway. More feedback and opinions on the framework and ideas as presented here are extremely valuable. The above is a draft and not finalized.
The process of further developing and bringing a suitable framework to protect Canadians will require the support of exchange operators, legal experts, and many others in the community. The costs of not doing such are tremendous. A large and convoluted framework, one based on flawed ideas or implementation, or one which fails to properly safeguard Canadians is not just extremely expensive and risky for all Canadians, severely limiting to the credibility and reputation of the industry, but an existential risk to many exchanges.
The responsibility falls to all of us to provide our insight and make our opinions heard on this critical matter. Please take the time to give your thoughts.

Bitcoin Hacks & basic ways to protect your Crypto

Interest in Bitcoin is increasing globally. More and more people are willing to participate in Bitcoin trading and mining. However, Bitcoin history shows that it is not always as safe as we would like it to be. Let’s take a look at some major Bitcoin hacks.

Allinvain

Allinvain is a nickname of a user on BitcoinTalk forums. Basically, he was the first one to experience a major Bitcoin loss. He lost 25,000 bitcoins, all together it was worth around $500,000. The user believed that someone hacked into his computer to steal BTC.

Mt Gox

Shortly after Allinvain’s case, the next hack attempt happened. Mt Gox was one of the biggest exchanges that provided a trade between Bitcoin and fiat money. Hackers compromised its website and started to sell Bitcoins. Their actions made the price go down dramatically. However, attackers did not pay attention to the $1000 limit Mt Gox had. Nonetheless, that hack attack had an important influence on BTC.

Other exchanges

Exchanges are being attacked by hackers quite often.
In 2012 Bitfloor suffered a terrible attack and lost 24,000 BTC (around $250,000). Unfortunately, this exchange was not able to survive the attack and was closed in 2013.
In 2015 Bitstamp exchange was hacked. It lost approximately 19,000 BTC (around $5 million).
In 2016 Bitfinex also lost 120,000 BTC (around $77 million) to hackers.

Twitter hack

The last attack happened in one of the biggest social nets. Twitter became a part of the latest attackers’ actions. The most significant and world-famous accounts promoted Bitcoin scam for several hours.

Anti-hack protection

The most important question is how to protect your Bitcoin savings from upcoming attacks. Here are some basic things that may help you to be safe:
Even though there is no way to be a hundred percent safe, there are a lot of steps we can take to avoid unfortunate losses. Cryptocurrency services are improving their protection systems all the time, and we all should do what we can to make this network more secure.

Crypto Weekly News — June, 19

What important crypto events happened last week?
📌 The U.S. District Court dismissed the appeal of the former CEO of the Bitcoin exchange Mt. Gox Mark Karpelès. He requested the removal of the fraud allegations made by the last remaining plaintiff. District Judge Gary S. Feinerman decided in favor of Gregory Green, the initiator of the class action lawsuit against Karpelès. The plaintiff insists that the head of the site did not provide an appropriate level of protection for user funds, accusing him of negligence and fraud.
📌 BitMEX exchange operator HDR Global Trading and OKCoin have granted $150,000 to Bitcoin Core developer Amiti Uttarvar who specializes in Bitcoin P2P level issues, being the author of a proposal to reduce the frequency of wallet attempts to relay transactions.
📌 The well-known Bitcoin investor Alistair Milne lost 1 BTC during a hacker attack, which he himself initiated. The purpose of the experiment was to find out how much data about the wallet would be enough to hack it. Milne created a separate Bitcoin address, transferred 1 BTC to it, and started laying out prompts to unravel a seed phrase of 12 words. When only 4 words remained, the hacker intervened and managed to brute force the remaining words in 44 hours.
📌 The creator of the Telegram messenger Pavel Durov warned of fraudulent schemes carried out allegedly on his behalf on Facebook and Instagram and noticed that such ads were approved by moderators of the platforms. Durov called on Facebook to organize the moderation of advertisements, and also expressed the hope that the company will compensate for the damage caused to users by the actions of moderators.
📌 Leading party functionaries in China have proposed a plan to create the central bank digital currency (CBDC) based on the currencies of China, Korea, Japan, and Hong Kong. A payment network with a regional CBDC could be part of the free trade agreement that Japan, Korea, and China are preparing to sign. The initiative will also allow China to expand its use of the renminbi internationally.
📌 Co-founder of the Centra Tech cryptocurrency project Robert Farkas pleaded guilty to organizing a $25 million fraudulent scheme. In 2018, Farkas, along with Sohrab Sharma and Raymond Trapani, was accused of cheating investors. The US Securities and Exchange Commission insisted that they provided knowingly false information about the partnership with Visa and Mastercard. Centra executives also assured investors that they are licensed to process money transfers in 38 states.
📌 As a result of the last recalculation of the complexity of Bitcoin mining, the indicator grew by 14.95% to 15.78 trillion hashes (T), approaching the pre-halving level.
📌 The non-custodial cryptocurrency P2P marketplace LocalCryptos opened up the possibility for users to buy and sell Litecoin (LTC) in addition to Bitcoin (BTC) and Ethereum (ETH). Previously, the platform was called LocalEthereum and supported the trading of the second largest cryptocurrency by capitalization. Along with a statement on adding support for other crypto assets, the marketplace rebranded. The first cryptocurrency added was Bitcoin.
📌 The Bitcoin.com cryptocurrency information portal account is blocked on YouTube. At the time of the ban, 40 thousand people were subscribed to the channel. By assumption, the blockage may be due to their political activity. Bitcoin.com founder Roger Ver called YouTube a tool for social media manipulation and censorship.
📌 Protocol Podcast host Eric Savix has lost all of Bitcoin's savings. On June 10, Savix downloaded the fake Google Chrome cryptocurrency extension Keep Key. He was not embarrassed by the requirement of the program to enter a seed phrase from the wallet. Thus, the hackers transferred all 12 BTC available to Savix (about $120 thousand at the time of the theft) to their account. The concerned community managed to collect a sixth of the stolen during the day.
📌 According to an official WhatsApp blog press release, users with Mastercard or Visa debit/credit cards of certain Brazilian banks now have an opportunity to send messages attaching their assets. The amount of payments is limited to twenty per day, however, the transaction size limit is not specified.
That’s all for now!

Crypto Weekly News — June, 19

What important crypto events happened last week?
📌 The U.S. District Court dismissed the appeal of the former CEO of the Bitcoin exchange Mt. Gox Mark Karpelès. He requested the removal of the fraud allegations made by the last remaining plaintiff. District Judge Gary S. Feinerman decided in favor of Gregory Green, the initiator of the class action lawsuit against Karpelès. The plaintiff insists that the head of the site did not provide an appropriate level of protection for user funds, accusing him of negligence and fraud.
📌 BitMEX exchange operator HDR Global Trading and OKCoin have granted $150,000 to Bitcoin Core developer Amiti Uttarvar who specializes in Bitcoin P2P level issues, being the author of a proposal to reduce the frequency of wallet attempts to relay transactions.
📌 The well-known Bitcoin investor Alistair Milne lost 1 BTC during a hacker attack, which he himself initiated. The purpose of the experiment was to find out how much data about the wallet would be enough to hack it. Milne created a separate Bitcoin address, transferred 1 BTC to it, and started laying out prompts to unravel a seed phrase of 12 words. When only 4 words remained, the hacker intervened and managed to brute force the remaining words in 44 hours.
📌 The creator of the Telegram messenger Pavel Durov warned of fraudulent schemes carried out allegedly on his behalf on Facebook and Instagram and noticed that such ads were approved by moderators of the platforms. Durov called on Facebook to organize the moderation of advertisements, and also expressed the hope that the company will compensate for the damage caused to users by the actions of moderators.
📌 Leading party functionaries in China have proposed a plan to create the central bank digital currency (CBDC) based on the currencies of China, Korea, Japan, and Hong Kong. A payment network with a regional CBDC could be part of the free trade agreement that Japan, Korea, and China are preparing to sign. The initiative will also allow China to expand its use of the renminbi internationally.
📌 Co-founder of the Centra Tech cryptocurrency project Robert Farkas pleaded guilty to organizing a $25 million fraudulent scheme. In 2018, Farkas, along with Sohrab Sharma and Raymond Trapani, was accused of cheating investors. The US Securities and Exchange Commission insisted that they provided knowingly false information about the partnership with Visa and Mastercard. Centra executives also assured investors that they are licensed to process money transfers in 38 states.
📌 As a result of the last recalculation of the complexity of Bitcoin mining, the indicator grew by 14.95% to 15.78 trillion hashes (T), approaching the pre-halving level.
📌 The non-custodial cryptocurrency P2P marketplace LocalCryptos opened up the possibility for users to buy and sell Litecoin (LTC) in addition to Bitcoin (BTC) and Ethereum (ETH). Previously, the platform was called LocalEthereum and supported the trading of the second largest cryptocurrency by capitalization. Along with a statement on adding support for other crypto assets, the marketplace rebranded. The first cryptocurrency added was Bitcoin.
📌 The Bitcoin.com cryptocurrency information portal account is blocked on YouTube. At the time of the ban, 40 thousand people were subscribed to the channel.

The biggest cryptocurrency thefts in the last 10 years

In this article, we will try to remember all the major theft of cryptocurrencies over the past 10 years.
1. Bitstamp $5.3 mln (BTC), January 4th, 2015
On January 4, 2015, the operational hot wallet of Bitstamp announced that it was hacked by an anonymous hacker and 19,000 Bitcoins (worth of $5 million) were lost.
The initiation of the attack fell on November 4, 2014. Then Damian Merlak, the CTO of the exchange, was offered free tickets to punk rock festival Punk Rock Holiday 2015 via Skype, knowing that Merlak is interested in such music and he plays in the band. To receive the tickets, he was asked to fill out a participant questionnaire by sending a file named “Punk Rock Holiday 2015 TICKET Form1.doc”. This file contained the VBA script. By opening the file, he downloaded the malware on his computer. Although Merlak did not suspect wrong and has opened the "application form", to any critical consequences, this did not open access to the funds of exchange.
The attackers, however, did not give up. The attack continued for five weeks, during which hackers presented themselves as journalists, then headhunters.
Finally, the attackers were lucky. On December 11, 2014, the infected word document was opened on his machine by Bitstamp system administrator Luka Kodric, who had access to the exchange wallet. The file came to the victim by email, allegedly on behalf of an employee of the Association for computer science, although in fact, as the investigation showed, the traces of the file lead deep into Tor. Hackers were not limited to just one letter. Skype attacker pretending to be an employee of the Association for computing machinery, convinced that his Frame though to make international honor society, which required some paperwork. Kodric believed.
By installing a Trojan on Kodriс's computer hackers were able to obtain direct access to the hot wallet of the exchange. The logs show that the attacker, under the account of Kodric, gained access to the server LNXSRVBTC, where he kept the wallet file.dat, and the DORNATA server where the password was stored. Then the servers were redirected to a certain IP address that belongs to one of the providers of Germany.
There are still no official reports of arrests in this case. Obviously, the case is complicated by the fact that the hackers are outside the UK, and the investigation has to cooperate with law enforcement agencies in other countries.
2. GateHub $9.5 mln (XRP), June 1th, 2019
Hackers have compromised nearly 100 XRP Ledger wallets on cryptocurrency wallet service GateHub. The incident was reported by GateHub in a preliminary statement on June 6.
XRP enthusiast Thomas Silkjær, who first noticed the suspicious activity, estimates that the hackers have stolen nearly $10 million worth of cryptocurrency (23,200,000 XRP), $5.5 million (13,100,000 XRP) of which has already been laundered through exchanges and mixer services.
GateHub notes that it is still conducting an investigation and therefore cannot publish any official findings. Also, GateHub advises victims to make complaints to the relevant authorities of their jurisdiction.
3. Tether, $30.9 mln (USDT), November 19th, 2017
Tether created a digital currency called "US tokens" (USDT) — they could be used to trade real goods using Bitcoin, Litecoin and Ether. By depositing $1 in Tether, the user received 1 USD, which can be converted back into fiat. On November 19, 2017, the attacker gained access to the main Tether wallet and withdrew $ 30.9 million in tokens. For the transaction, he used a Bitcoin address, which means that it was irreversible.
To fix the situation, Tether took action by which the hacker was unable to withdraw the stolen money to fiat or Bitcoin, but the panic led to a decrease in the value of Bitcoin.
4. Ethereum, $31 mln (ETH), July 20th, 2017
On July 20, 2017, the hacker transferred 153,037 Ethers to $31 million from three very large wallets owned by SwarmCity, Edgeless Casino and Eternity. Unknown fraudster managed to change the ownership of wallets, taking advantage of the vulnerability with multiple signatures.
First, the theft was noticed by the developers of SwarmCity.
Further events deserve a place in history: "white hackers" returned the stolen funds, and then protected other compromised accounts. They acted in the same way as criminals, who stole funds from vulnerable wallets — just not for themselves. And it all happened in less than a day.
5. Dao (Decentralized Autonomous Organization) $70 mln (ETH), June 18th, 2016
On June 18, 2016, members of the Ethereum community noticed that funds were being drained from the DAO and the overall ETH balance of the smart contract was going down. A total of 3.6 million Ether (worth around $70 million at the time) was drained by the hacker in the first few hours. The attack was possible because of an exploit found in the splitting function. The attackes withdrew Ether from the DAO smart contract multiple times using the same DAO Tokens. This was possible due to what is known as a recursive call exploit.
In this exploit, the attacker was able to "ask" the smart contract (DAO) to give the Ether back multiple times before the smart contract could update its own balance. There were two main faults that made this possible: the fact that when the DAO smart contract was created the coders did not take into account the possibility of a recursive call, and the fact that the smart contract first sent the ETH funds and then updated the internal token balance.
It's important to understand that this bug did not come from Ethereum itself, but from this one application that was built on Ethereum. The code written for the DAO had multiple bugs, and the recursive call exploit was one of them. Another way to look at this situation is to compare Ethereum to the Internet and any application based on Ethereum to a website: if a website is not working, it doesn't mean that the Internet is not working, it simply means that one website has a problem.
The hacker stopped draining the DAO for unknown reasons, even though they could have continued to do so.
The Ethereum community and team quickly took control of the situation and presented multiple proposals to deal with the exploit. In order to prevent the hacker from cashing in the Ether from his child DAO after the standard 28 days, a soft-fork was voted on and came very close to being introduced. A few hours before it was set to be released, a few members of the community found a bug with the implementation that opened a denial-of-service attack vector. This soft fork was designed to blacklist all the transactions made from the DAO.
6. NiceHash, 4736.42 (BTC), December 6th, 2017
NiceHash is a Slovenian cryptocurrency hash power broker with integrated marketplace that connects sellers of hashing power (miners) with buyers of hashing power using the sharing economy approach.
On December 6, 2017, the company's servers became the target of attack. At first, Reddit users reported that they could not access their funds and make transactions — when they tried to log in, they were shown a message about a service interruption. In the end, it became known that the service had undergone a major cyberattack and 4736,42 Bitcoins disappeared without a trace.
Despite heavy losses, NiceHash was able to continue working, but CEO and founder Marco Koval resigned, giving way to a new team. The company managed to maintain the trust of investors and began to strengthen the protection of its systems.
7. Mt.Gox, 850000 (BTC), June 19th, 2011
The Hacking Of Mt.Gox was one of the biggest Bitcoin thefts in history. It was the work of highly professional hackers using complex vulnerabilities.
A hacker (or a group of hackers) allegedly gained access to a computer owned by one of the auditors and used a security vulnerability to access Mt.Gox servers, then changed the nominal value of Bitcoin to 1 cent per coin.
Then they brought out about 2000 BTC. Some customers, without knowing it, conducted transactions at this low price, a total of 650 BTC, and despite the fact that the hacking hit the headlines around the world, no Bitcoin could be returned.
To increase investor confidence, the company has compensated all of the stolen coins, placed most of the remaining funds in offline storage, and the next couple of years was considered the most reliable Bitcoin exchanger in the world.
However, it was only an illusion of reliability.
The problems of the organization were much more serious, and the management probably did not even know about them.
CEO of Mt.Gox, Mark Karpeles, was originally a developer, but over time he stopped delving into technical details, basking in the rays of glory — because he created the world's largest platform for cryptocurrency exchange. At that time Mt.Gox handled over 70% of all Bitcoin transactions.
And, of course, there were those who wanted to take advantage of the technological weakness of the service. At some point, hackers made it so that Bitcoins could be bought at any price, and within minutes millions of dollars worth of coins were sold — mostly for pennies. World prices for Bitcoin stabilized in a few minutes, but it was too late.
As a result, Mt.Gox lost about 850,000 Bitcoins. The exchange had to declare bankruptcy, hundreds of thousands of people lost money, and the Japanese authorities arrested CEO Mark Karpeles for fraud. He pleaded not guilty and was subsequently released. In 2014, the authorities restored some of the Bitcoins remaining at the old addresses, but did not transfer them to the exchange, and created a trust to compensate for the losses of creditors.
8. Coincheck, $530 mln, January 26th, 2018
The sum was astonishing, and even surpassed the infamous Mt.Gox hack.
While Mt.Gox shortly filed for bankruptcy following the hack, Coincheck has surprisingly remained in business and was even recently approved as a licensed exchange by Japan’s Financial Services (FSA).
Coincheck was founded in 2014 in Japan and was one of the most popular cryptocurrency exchanges in the country. Offering a wide variety of digital assets including Bitcoin, Ether, LISK, and NEM, Coincheck was an emerging exchange that joined the Japan Blockchain Association.
Since Coincheck was founded it 2014, it was incidentally not subject to new exchange registration requirements with Japan’s FSA — who rolled out a framework after Mt. Gox –, and eventually was a contributing factor to its poor security standards that led to the hack.
On January 26th, 2018, Coincheck posted on their blog detailing that they were restricting NEM deposits and withdrawals, along with most other methods for buying or selling cryptocurrencies on the platform. Speculation arose that the exchange had been hacked, and the NEM developers issued a statement saying they were unaware of any technical glitches in the NEM protocol and any issues were a result of the exchange’s security.
Coincheck subsequently held a high-profile conference where they confirmed that hackers had absconded with 500 million NEM tokens that were then distributed to 19 different addresses on the network. Totaling roughly $530 million at the time — NEM was hovering around $1 then — the Coincheck hack was considered the largest theft in the industry’s history.
Coincheck was compelled to reveal some embarrassing details about their exchange’s security, mentioning how they stored all of the NEM in a single hot wallet and did not use the NEM multisignature contract security recommended by the developers.
Simultaneously, the NEM developers team had tagged all of the NEM stolen in the hack with a message identifying the funds as stolen so that other exchanges would not accept them. However, NEM announced they were ending their hunt for the stolen NEM for unspecified reasons several months later, and speculation persisted that hackers were close to cashing out the stolen funds on the dark web.
Mainstream media covered the hack extensively and compared it to similar failures by cryptocurrency exchanges in the past to meet adequate security standards. At the time, most media coverage of cryptocurrencies was centered on their obscure nature, dramatic volatility, and lack of security. Coincheck’s hack fueled that narrative considerably as the stolen sum was eye-popping and the cryptocurrency used — NEM — was unknown to most in the mainstream.
NEM depreciated rapidly following the hack, and the price fell even more throughout 2018, in line with the extended bear market in the broader industry. Currently, NEM is trading at approximately $0.07, a precipitous fall from ATH over $1.60 in early January.
The extent of the Coincheck hack was rivaled by only a few other hacks, notably the Mt.Gox hack. While nominally Coincheck is the largest hack in the industry’s history, the effects of Mt.Gox were significantly more impactful since the stolen funds consisted only of Bitcoin and caused a sustained market correction as well as an ongoing controversy with the stolen funds and founder. Moreover, Mt.Gox squandered 6% of the overall Bitcoin circulation at the time in a market that was much less mature than it is today.
Despite the fallout, Coincheck is now fully operational and registered with Japan’s FSA.
As practice shows, people make mistakes and these mistakes can cost a lot. Especially, when we talk about mad cryptoworld. Be careful and keep your private keys in a safe place.
