Protonmail Disabled My Binance Cryptocurrency Exchange Email Account | €500 Worth of Bitcoin Lost
On 10th November I have created a new account on the Binance cryptocurrency exchange. Binance accounts need to be associated with an email account and I created a free ProtonMail account for this purpose. The reason for choosing ProtonMail over say Gmail or Yahoo is due to the fact that Protonmail is more secure. Basically, I thought that my Binance account would be safer if it was associated with a ProtonMail email account as was any Bitcoin or any other cryptocurrency deposited in the same Binance account. My internet connection does not use a fixed IP address and in order to login into this new Binance account, I need to open my new ProtonMail email account, open an email that is sent from Binance and click on a confirmation link in the email to confirm that the IP address indicated in the email is mine. Without clicking the confirmation link, I cannot access the Binance account. Email confirmation is also required for withdrawing funds from Binance, as is probably the case with any other major cryptocurrency exchange. In other words, if one loses access to the email account that is associated with a cryptocurrency exchange account, that person can no longer withdraw any cryptocurrencies from the account. This practically means that both the account and any Bitcoin and/or other cryptocurrencies in the account will become useless. Anyway, to continue with my story, on 18th November I tried to log in into my new Binance account. I entered my email/username and password, inputted the 2FA code from Google Authenticator and I got the usual pop-up message from Binance stating that I need to confirm my IP address by clicking the confirmation link in an email sent from Binance. So I opened the ProtonMail site and I entered my email address, password and 2FA code. To my surprise, I was unable to log in successfully as I got a message stating that my ProtonMail account has been disabled for abuse or fraud. I immediately sent an email to [[email protected]](mailto:[email protected]) as indicated in the message and asked for my account to be unblocked. The next day, I received the following reply from ProtonMail: “The account was automatically disabled by our anti-spam system due to a suspicious activity. The account will not be enabled.” I wrote to ProtonMail again and explained to support that I did not use the email account for any illicit purposes. I also explained to the ProtonMail staff that I need to access the email account because it is tied to a Binance account. However, the next day ProtonMail's support replied in the following manner: “Your account cannot be enabled since we believe that it is for abuse.” I send another email to the ProtonMail abuse team and explained to them that without access to the ProtonMail account I will lose access to the Bitcoin and other cryptocurrencies worth €500 that are stored in the Binance account that is associated to the disabled email account. I also asked the ProtonMail staff if they could escalate the ticket to management or if they will be willing to help me if I become a paid ProtonMail customer. I received no reply to my email so the next day I sent another email to the abuse team and pleaded for help. I told ProtonMail’s support that I do not even need to send emails from the deactivated account. I explained to support that the only reason why I need to access the email account is to be able to read emails from Binance and click on any confirmation links. ProtonMail’s next reply was the following: “Our team has examined your account once again and it will not be enabled. You will not be able to access your messages anymore or reuse the account.” I really cannot understand why ProtonMail’s staff have treated me in this manner. My disabled account was just a few days old when it was deactivated. I only had a few, maybe six or seven emails, in the inbox folder with three emails coming from ProtonMail and the rest coming from Binance. The thing is that, as far as I know, I did not even send a single email before the account was disabled. How did ProtonMail 's staff come to the conclusion that I wanted to use the email account for abuse? I am not stupid so if I wanted to use an email account to spam somebody, I surely would not use an email account that is tied to a cryptocurrency exchange account! Not knowing what to do, I did a Google search to see if other people have been burnt by ProtonMail’s support after getting their accounts disabled. Not surprisingly, it seems that there are many other ProtonMail users who had their accounts disabled because of some “faulty” anti-spam filter. Apparently many users got their accounts suspended because they were using a VPN service while using their ProtonMail account. I too have a subscription to a VPN service and I would not exclude that ProtonMail’s spam filter flagged my account as suspicious due to the fact I was using the VPN service at the time. While I can understand that no anti-spam filter is perfect, the real problem is that ProtonMail does not seem to care about its existing customers and potential future customers. I doubt that ProtonMail’s staff have done any effort to examine my mailbox and those of other disabled accounts. Anyway, it is unfortunate that I had to learn the hard way the mistake I made in thinking that I would be better off in using ProtonMail to secure my Binance exchange account instead of Google, Yahoo or some other email service provider. While ProtonMail might be more secure, I am not aware that Google and Yahoo deactivate accounts for accessing the email accounts over a VPN network or for no other valid reason. What is the use of using a more secure email service if there is a high risk of getting email accounts disabled without doing anything wrong? Although I will probably never get hold of my €500 worth of Bitcoin again, I hope that at least anyone thinking of using ProtonMail for cryptocurrency exchange accounts, work related accounts, bank related correspondence or even for personal use will find my story useful and will consider all pros and cons before taking a decision. The fact that my ProtonMail account was disabled is kind of having my €500 worth of Bitcoin being held hostage by ProtonMail. ProtonMail does not have access to the cryptocurrencies in my Binance account but neither do I at this point. It is like I had two different keys to unlock the repository where the cryptocurrencies are stored and ProtonMail confiscated one of the keys. There is no need to say that I have worked hard for those €500, but what if I had €5,000 or even €50,000 worth of cryptocurrencies in that Binance account? How many cryptocurrencies and cryptocurrency exchange accounts will be lost forever because of ProtonMail’s actions? ProtonMail’s “faulty” anti-spam filter is probably doing the company more harm than good. However, it is only ProtonMail’s fault for not doing anything about the issue, playing the bullies game, pretending to examine disabled accounts while providing no real evidence of abuse and being insensitive to the fact that disabled accounts can lead to loss of money, loss of business or loss of personal data. UPDATE on 26th November: After providing proof that I am not a spammer, ProtonMail's abuse team contacted me this morning to inform me that my account has been enabled. I can confirm that the email account is working fine again. Thank you ProtonMail for your understanding.

First of all,please upvote for visibility + more opinions- this concernsall of us. Also, if you're stupid enough to think you'll get away with avoiding tax's despite KYC'ing to Coinbase & Binance don't bother commenting. News flash! you're gonna end up paying that tax in the long run + huge fines eating into your gains (or even putting you into debt). Anyways... I started investing in 2017. As a noob I did what most people did, chased multiple shitcoins, bought and sold various different pumps getting wrecked along the way. Then towards the end of the year, my portfolio increased significantly... but I DIDN'T sell - so I didn't "crystalise" any gainz. (I sold a couple hundred here and there during hard financial times, but I'm guessing nothing close to the free capital gains allowance). Fast forward just over 2 years, since then I've been buying BTC/ETH/XMR on a consistent basis. It's getting to the point where if I were to sell enough of my stack, I'd owe tax as it'd be over the "allowed" CGT threshold. That leads me to my question... how the fuck are you supposed to calculate capital gains tax when it comes to crypto? For the past 3 years I've traded in and out of alt-coins on multiple exchanges (some of which don't even exist anymore). It would be easy if it was just FIAT IN vs FIAT OUT, but the fact that CRYPTO to CRYPTO is considered taxable just makes it a nightmare! On top of that I did some freelance work (paid in BTC) which adds to the complexity. Take another example of what confuses me: Say I bought 1BTC on Coinbase in 2017, then 1BTC on Kraken in 2018, then 0.5BTC on Coinbase again in 2019, and hold them all in the same wallet. Then if I were to sell 0.5BTC in 2020, what Bitcoin was actually sold? Half of the 1 BTC bought in 2017? Is it FIFO? I genuinely don't know where to start and need help. I don't want to be in a shitty situation (for example some massive 2017-esque bull run happens just before the end of the tax year and I decide to cash out and have 3 days to sort shit out). I want to be prepared. I've come across services such as https://www.cointracker.io/ /https://bitcoin.tax/ etc but feel really hesitant to give quasi-unknown companies full read access to my wallet addresses, portfolio amount, personal email address etc. Privacy is key in the crypto space and I don't want another attack vector especially after seeing much more established companies such as Ledger fucking up (idiots) and losing my personal data. What do I do? I've even thought of selling EVERYTHING to FIAT and immediately buying it all back and taking whatever fine comes my way on the chin just so I can clearly track crypto transactions and not have to stress about it. If anyone has experience with crypto tax's please share any information that may be valuable to me/all the many others that are in the same situation as me. TL;DR: Bought loads of Bitcoin and Shitcoins throughout the past 3 years, finally starting to total up to an amount that'd be taxable if I sold a chunk - dafuq do I do regarding Taxes?
I registered a Kraken account many years ago, never did any trades, but entered my real name and location, since they failed to verify my location I abandoned the exchange. The thing is, I wanted to try again with a separate account, but I don't want to be linked to that old account once I do further KYC. I used that same email account in faucets and other stuff.. so I don't want to be linked to that. And I can't even access the email account anymore, so I don't know what exactly was there. Should I just use another exchange? Ive thought about Binance to not use Coinbase. Im not from the US so I don't want my stuff to be sent to the IRS, thats retarded. Anyway, buying Bitcoin is a pain in the ass these days, banks are blocking transacions and you have to show up in the bank and explain you aren't a terrorist. I don't want to buy in Bisq or whatever, because when I cash out I want to be able to buy a house or anything else that aren't stupid gift cards so im not bothered about privacy anyway, but Coinbase is just too much.
Dragonchain Great Reddit Scaling Bake-Off Public Proposal
Dragonchain Public Proposal TL;DR:
Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and postsper Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625. Watch Joe walk through the entire proposal and answer questions onYouTube. This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!
I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale. For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube. We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoC
In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks. 24 hours in 4 minutes (YouTube): 24 hours in 4 minutes The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period. Tooling to reproduce our demo is available here: https://github.com/dragonchain/spirit-bomb
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired. Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity. TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block. TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain. With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times. We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment. Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in Scaling
Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems. We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
LBRY - To allow users to deploy content natively to LBRY
MakerDAO to allow users to lend small amounts backed by their Reddit community points.
STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction. Dragonchain Fees Table
How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node. Getting started is easy...
Download Dragonchain’s dctl
Input three commands into a terminal
Build an image
More information can be found in our Get started documents.
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain. Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain. After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks. Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD. For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments. Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users. Over a 5 day period, your scaling PoC should be able to handle: *100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes. Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum. Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
Operational on-premises capabilities
Operational deployment to any datacenter
Over 700 independent Community Verification Nodes with proof of ownership
Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node. Examples:
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users. All of Reddit's Transactions on Blockchain (month) Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees. Reddit Internal Token Transaction Fees Reddit Ethereum Token Transaction Fees When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
In a combination of the above, customers could cover aggregated fees.
Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.
Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here. Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here. In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here. A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible APIs should be well documented and stable
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected. Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR. Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus points Public, third-party implementation review available or in progress
Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).
Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open Source
The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group. https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html
In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney. Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
Obtain VP support and approval for the release
Verify ownership of the software to be released
Verify that no proprietary content would be released
Convince the organization that there was a value to the open source community
Convince the organization that there was a value to Disney
Offer the plan for ongoing maintenance of the project outside of Disney
Itemize competing projects
Verify no conflict of interest
Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
Obtain legal approval
Approval from corporate, parks, and other business units
Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
Trademark searches conducted for the selected name Dragonchain
Obtain IT security approval
Manual review of OSS components conducted
OWASP Dependency and Vulnerability Check Conducted
Obtain technical (software) approval
Offer management, process, and financial plans for the maintenance of the project.
Meet list of items to be addressed before release
Remove all Disney project references and scripts
Create a public distribution list for email communications
Remove Roets’ direct and internal contact information
Create public Slack channel and move from Disney slack channels
Create proper labels for issue tracking
Rename internal private Github repository
Add informative description to Github page
Expand README.md with more specific information
Add information beyond current “Blockchains are Magic”
Add getting started sections and info on cloning/forking the project
Add installation details
Add uninstall process
Add unit, functional, and integration test information
Detail how to contribute and get involved
Describe the git workflow that the project will use
Move to public, non-Disney git repository (Github or Bitbucket)
Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney. The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Sàn OKEx và tất tần tật những điều liên qua mà bạn cần phải biết
Tìm kiếm sàn giao dịch tiền điện tử phù hợp để tham gia là một trong những nhiệm vụ quan trọng nhất đối với bất kỳ nhà đầu tư tiền điện tử nào. Trong bài viết này chúng tôi trình bày chi tiết và mang đến cho bạn những thông tin quan trọng nhất về OKEx Exchange. Trong này chúng tôi sẽ giải quyết các câu hỏi phổ biến như “Sàn giao dịch OKEx có an toàn không? Chúng tôi sẽ xem xét lý do tại sao một nhà đầu tư tiền điện tử có thể sử dụng sàn OKEx để trao đổi tiền điện tử, nêu lên nhược điểm và chỉ cho bạn cách để bắt đầu trao đổi mua bán trong mục hướng dẫn. Đừng bỏ lỡ bất kỳ chi tiết quan trọng nào về sàn OKEx nhé.
OKEx là gì?
https://preview.redd.it/zi3zxvppwrx51.png?width=800&format=png&auto=webp&s=c83e13d0d227adecffed24c3d4e5d4a20e298179 Sàn OKEx Sàn giao dịch OKEx là sàn giao dịch tiền điện tử hàng đầu cho phép bạn mua và bán các loại tiền điện tử khác nhau. Sàn giao dịch được thành lập vào năm 2014 và được hỗ trợ bởi các quỹ đầu tư mạo hiểm như Giant Network Group, Longling Capital, Ceyuan Ventures, Qianhe Capital Management, eLong Inc và Ventures Lab (đồng sáng lập bởi nhà đầu tư blockchain Tim Draper) với hàng triệu đô la vào các khoản đầu tư. Vào ngày 11 tháng 4 năm 2018, công ty đã công bố mở rộng sang Malta, với nỗ lực cung cấp khuôn khổ quy định hợp lý cho các doanh nghiệp blockchain và trao đổi tài sản kỹ thuật số. Tháng 5 năm 2018, sàn giao dịch này đã trở thành sàn giao dịch tiền điện tử lớn nhất thế giới theo doanh thu được báo cáo. Đến tháng 6 năm 2018, nền tảng này đã trở thành một trong những sàn giao dịch lớn nhất ra mắt và cung cấp dịch vụ nhãn trắng để trao đổi tiền điện tử với điều kiện người đăng ký phải có kinh nghiệm trong ngành vững chắc và 2,5 triệu đô la trong tài khoản của họ. Vào ngày 25 tháng 11 năm 2019, công ty đã công bố bốn đối tác chính cho mã token tiện ích toàn cầu “OKB”. Vào tháng 2 năm 2020, OKEx thông báo rằng blockchain của riêng họ có tên là OKChain sẽ bắt đầu thử nghiệm. Sàn giao dịch tiền điện tử có trụ sở tại Malta lần đầu tiên tiết lộ rằng họ đang phát triển một sàn giao dịch phi tập trung (DEX) được xây dựng trên nền tảng của nó vào tháng 3 năm 2020. Hiện tại, OKEx có khối lượng trao đổi tiền điện tử cao thứ hai trên toàn cầu và không còn xa nữa sẽ cạnh tranh với Binance để giành vị trí dẫn đầu. Điều này có nghĩa là một số thị trường tiền điện tử do OKEx cung cấp là lớn nhất trên thế giới. Khi sàn giao dịch mở rộng cơ sở khách hàng ra ngoài châu Á, hy vọng sàn giao dịch này sẽ tiếp tục phát triển và đè nặng áp lực lên Binance để giành thị phần. Ban đầu, công ty có trụ sở tại Hồng Kông. Tuy nhiên, vào tháng 4 năm 2018, sàn giao dịch OKEx đã xác nhận rằng họ sẽ chuyển đến Malta. Giám đốc điều hành OKEx giải thích rằng Malta không chỉ là một quốc gia thân thiện với blockchain mà còn có các quy định nghiêm ngặt hơn về các tiêu chuẩn chống rửa tiền. Sàn giao dịch cởi mở và nói rằng những tiêu chuẩn này rất quan trọng để bảo vệ khách hàng của họ và đây là động lực quan trọng cho việc di chuyển. Điều này có nghĩa là nếu bạn đang tìm kiếm một sàn giao dịch có quy định chặt chẽ hơn về tiền điện tử, thì OKEx có thể là một trong những sàn giao dịch phù hợp với bạn.
Các loại tiền được phép giao dịch : Hơn 100 loại tiền điện tử khác nhau có sẵn trên sàn giao dịch.
Sàn giao dịch lớn thứ hai: Dựa trên khối lượng giao dịch, OKEx là sàn giao dịch tiền điện tử lớn thứ hai trên toàn cầu trong các sàn tiền ảo.
OKEx được sử dụng ở những quốc gia nào? Sàn giao dịch chấp nhận hầu hết các quốc gia từ Châu Á và Châu Âu. Hiện tại, sàn giao dịch có khách hàng từ hơn 100 quốc gia khác nhau.
Gửi tiền thông thường: Không giống như các sàn giao dịch như Binance, OKEx cho phép gửi tiền thông thường qua chuyển khoản ngân hàng, Apple Pay và WeChat Pay.
Bạn có thể sử dụng thẻ tín dụng trên sàn giao dịch OKEx không? Có, sàn giao dịch hỗ trợ thanh toán bằng thẻ tín dụng.
Tính thanh khoản cao: Vấn đề với các sàn giao dịch nhỏ là số lượng lệnh bán có thể bị thiếu hụt. Điều này có nghĩa là nếu một nhà đầu tư muốn mua một loại tiền điện tử trị giá thậm chí là 500 đô la, giá có thể cao hơn. Tính thanh khoản cao có nghĩa là các nhà đầu tư có thể mua loại tiền điện tử đã chọn của họ trong một lần và với cùng một mức giá. OKEx có tính thanh khoản cao thứ hai trên thế giới và điều này giúp việc mua tiền điện tử ở đó trở nên dễ dàng.
Đòn bẩy giao dịch: Sàn giao dịch OKEx cung cấp đòn bẩy gấp ba lần trong giao dịch tiền điện tử.
Phí giao dịch trên sàn OKEx
Hầu hết mọi người sẽ không giao dịch trị giá nhiều hơn 600 Bitcoin khối lượng giao dịch trong 30 ngày. Điều này có nghĩa là phần lớn các nhà đầu tư tiền điện tử sử dụng sàn giao dịch sẽ vẫn ở mức 1. Phí giao dịch cấp 1 là:
Giao dịch thị trường: 0,15% phí nhà sản xuất và 0,2% phí tham gia.
Giao dịch kỳ hạn: 0,03% phí nhà sản xuất và 0,05% phí tham gia.
Giới hạn thanh toán trong 24 giờ: 100 Bitcoin

Đánh giá về sàn OKEx
Dưới đây là một số ưu, nhược điểm của sàn OKex mà người dùng đã đánh giá
Có được quyền truy cập vào hơn 100 loại tiền điện tử khác nhau.
Về khối lượng giao dịch, OKEx đứng thứ hai sau Binance.
Sàn giao dịch đã nhận được các khoản đầu tư từ nhiều công ty đầu tư mạo hiểm có uy tín. Thông thường, các nhà đầu tư mạo hiểm khá thông minh và rõ ràng nghĩ rằng họ đã hỗ trợ một cuộc trao đổi tuyệt vời.
OKEx cung cấp các tính năng giao dịch đặc biệt như giao dịch ký quỹ lên đến 10X và đối với giao dịch phái sinh, bạn có thể sử dụng đòn bẩy lên đến 100 lần.
Sàn giao dịch đã được giao dịch trong bốn năm và được thiết lập tốt.
Giao diện đơn giản giúp giao dịch tương đối dễ dàng.
OKEx có hỗ trợ tiền tệ fiat VND rất phù hợp với các nhà đầu tư Việt Nam.
Người mới bắt đầu có thể cảm thấy khó khăn khi sử dụng.
Giao diện người dùng không thân thiện.
Các khoản phí vẫn cao so với một số sàn giao dịch tiền điện tử.
Không thể sử dụng các loại tiền tài trợ khác nhau trong giao dịch ký quỹ.
Không chấp nhận tiền tệ fiat để gửi tiền.
Hướng dẫn mở tài khoản OKEx
OKEx cung cấp cho các nhà đầu tư tiền điện tử một loạt các loại tiền điện tử để lựa chọn. Nó cũng cung cấp các tính năng bổ sung như giao dịch đòn bẩy, giao dịch ký quỹ… Chúng tôi cũng rất thích việc OKEx nhận ra rằng ứng dụng dành cho thiết bị di động là một ý tưởng hay và không thể đợi ứng dụng iOS và Android ra mắt đúng cách. Không giống như các sàn giao dịch tiền điện tử khác như Binance, OKEx cung cấp khả năng gửi tiền tệ Fiat qua chuyển khoản ngân hàng, Alipay hoặc WeChat Pay. Điều này làm cho việc tham gia vào thị trường tiền điện tử trở nên dễ dàng hơn.
Đăng ký sàn OKEx
Điều đầu tiên bạn cần làm khi truy cập trang web OKEx là kiểm tra xem bạn có đang ở trên trang web chính thức hay không. Nhiều kẻ lừa đảo tạo ra các trang web tiền điện tử giả để mô phỏng các sàn giao dịch thực. Để thực hiện kiểm tra, hãy nhìn vào thanh URL trong trình duyệt web của bạn và đảm bảo rằng bạn thấy biểu tượng ổ khóa và dòng chữ “Secure”. Sau đó, bạn hãy sẵn sàng để nhấp vào nút đăng ký.
Điền vào mẫu đăng ký
Bạn có thể đăng ký bằng số điện thoại hoặc email. Bạn quyết định phương pháp nào phù hợp với mình. Tuy nhiên chúng tôi khuyên bạn nên đăng ký trao đổi qua e-mail. Nhập địa chỉ e-mail của bạn và nhấp vào “Request code”. Thao tác này sẽ gửi một mã gồm sáu chữ số đến địa chỉ email của bạn, mã này bạn nhập vào trường “Enter Code”. Sau đó, bạn có thể nhập các thông tin cần thiết, kiểm tra xem bạn đã đọc các điều khoản và điều kiện chưa, và nhấp vào nút ‘Register’.Bạn cũng sẽ nhận được một email tự động xác nhận rằng đăng ký của bạn đã thành công. https://preview.redd.it/7ns1qwrrwrx51.png?width=800&format=png&auto=webp&s=8ad6973d8ef20ccce1b040783e5cbf80f6c95e9f Đăng ký sàn OKEx
Việc bảo mật cho tài khoản khi giao dịch tiền ảo là rất quan trọng. Vì vậy các nhà đầu tư cần phải chú ý hoàn thành việc bảo mật tài khoản trước khi thực hiện bất cứ giao dịch nào. Ở biểu tượng tài khoản cá nhân, nhấp chọn Security Settings để tiến hành các bước bảo mật cho tài khoản.
Funds Password: Thiết lập mật khẩu cho ví của bạn, mật khẩu sau khi được thiết lập sẽ luôn được yêu cầu mỗi khi bạn thực hiện hành động rút tiền.
Mobile Verification: Xác thực số điện thoại. Sau khi số điện thoại của bạn được xác thực thì đây cũng chính là nơi sẽ gửi mã xác nhận về mỗi khi bạn tiến hành rút tiền, thay đổi mật khẩu tài khoản hoặc bất kỳ hoạt động nào liên quan đến bảo mật tài khoản.
Google Authenticator: Bật Google Authenticator để tăng cường tính bảo mật cho tài khoản. Việc bật xác thực thông qua app Google Authenticator rất đơn giản. Chỉ việc tải app về điện thoại và quét mã được cung cấp. Sau đó nhập mã xác thực được hiện thị.
Anti-Phishing Code: Mã chống lừa đảo. Sau khi bật chức năng này thì bất kỳ email xác thực nào được gửi từ OKEx đều sẽ kèm theo mã này.
Nhấp vào P2p Trade bên cạnh Quick Trade để chuyển đến phần giao dịch P2P. Tiếp theo, nhấp vào menu thả xuống tiền tệ và chọn đơn vị tiền tệ bạn muốn. Bạn có thể nhấp vào Sell để xem lại các đề nghị bán có sẵn hoặc chọn Order Book xem lại tất cả các lệnh mua và bán hiện có. Hiện tại thì sàn OKEx chỉ mới hỗ trợ người dùng Việt Nam nên các giao dịch của người Việt trên sàn này vẫn còn khá ít (hầu như là không có). Cuối cùng, chỉ cần xác nhận chi tiết giao dịch của bạn. https://preview.redd.it/693hmoivwrx51.png?width=800&format=png&auto=webp&s=bd1661297af24014068538e0f8fcfe7ef00b2754 Giao dịch P2P trên sàn OKex
Nhấp vào bên cạnh P2P Trade để chuyển đến phần Block Trade. Tiếp theo, nhấp vào menu thả xuống các loại tiền tệ và chọn đơn vị tiền tệ bạn muốn. Các loại tiền tệ fiat có sẵn cho giao dịch khối là:
Việc lựa chọn sàn giao dịch tiền điện tử là một quyết định rất cá nhân. Sự trao đổi tốt nhất cho một người có thể là sự lựa chọn sai lầm cho người khác. Sàn OKEx chắc chắn có sự hỗ trợ mạnh mẽ từ các nhà đầu tư mạo hiểm và một trong các sàn tiền ảo lớn nhất trên thị trường. Nó cũng cung cấp cho khách hàng nhiều tính năng hơn các sàn giao dịch khác, làm cho sàn giao dịch trở nên hấp dẫn hơn đối với các nhà giao dịch tiền điện tử có kinh nghiệm.

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.

Ưu và nhược điểm khi mua tiền ảo bằng visa
Đánh giá một số ưu và nhược điểm của hình thức mua tiền qảo thông qua thể tín dụng
Ưu điểm của việc mua bitcoin bằng visa
Ưu điểm chính của việc sử dụng thẻ tín dụng để mua bitcoin là giao dịch diễn ra ngay lập tức. Điều này không giống như các phương thức thanh toán khác như chuyển khoản ngân hàng, nơi bạn có thể phải đợi vài ngày trước khi giao dịch hoàn tất. Nếu bạn muốn mua bitcoin nhanh chóng, vì bạn đang suy đoán rằng giá của nó sẽ tăng theo cấp số nhân trong vài giờ hoặc vài ngày, thẻ tín dụng thực sự có thể là phương thức mua hàng tốt nhất vì nó ngay lập tức. Khi mua Bitcoin bằng các phương pháp truyền thống, bạn buộc phải quy đổi tiền của mình thành loại tiền tệ đúng với yêu cầu giao dịch trên nền tảng internet. Tuy nhiên, nếu mua bitcoin bằng thẻ visa thì bạn hoàn toàn có thể mua bằng sô tiền hiện có trong tài khoản mà không phải thực hiện bất kỳ quy đổi nào.
Một chút rắc rối khi mua tiền ảo bằng visa
Thật không may, có một nhược điểm phải kể đến là nhiều sàn giao dịch đặt các khoản phí khổng lồ đối với các giao dịch thẻ tín dụng. Ví dụ, tại Bitstamp, khoản phí này là 5% đáng kinh ngạc. Các phương thức thanh toán khác như chuyển khoản ngân hàng thu hút ít phí hơn (ví dụ: phí gửi tiền của Bitstamp cho chuyển khoản ngân hàng là 0,05% trong khi phí giao dịch cao nhất là 0,25%). Có một vấn đề là một số sàn giao dịch tiền điện tử thường áp dụng giới hạn giao dịch khi mua bitcoin bằng thẻ tín dụng. Người dùng trên một số sàn giao dịch mua bitcoin bằng thẻ tín dụng có giới hạn giao dịch hàng ngày thay đổi tùy thuộc vào hồ sơ và lịch sử của họ trên sàn giao dịch. Đối với bạn, nó có thể là 500$, trong khi đối với người khác, nó có thể là 1000$. Các giới hạn thường được đưa ra nhằm mục đích phòng chống gian lận và bảo mật.
