Op Ed: Lessons From a Cryptocurrency Hack (A Public Service Announcement)

Op Ed: Lessons From a Cryptocurrency Hack (A Public Service Announcement)

Cryptocurrency-related cyber attacks are on the rise. As cryptocurrency continues to explode in value and public awareness, we can only expect this trend to continue. I was recently the target of such an attack. I also personally know of multiple other cases of the same attack being successfully carried out. Even worse, this type of attack is becoming ever more common and is likely to see an even bigger boost thanks to the professional excellence of firms like Equifax, making it an urgent topic as almost everyone is at immediate risk.


This article describes this increasingly common attack vector and provides immediate steps you can take to protect yourself. I will also provide additional tools and best practices to further safeguard yourself and your funds more generally.


As a computer programmer active in the crypto ecosystem since early 2013, I’ve always been too aware of the constant threat of cybersecurity attacks and the possibility that I could be targeted at any time. Cryptocurrency is the perfect hacker pay day. Once it’s transferred away from your control it’s gone forever, and it’s easily liquidated in any number of ways. Black hats are constantly prowling for possible cryptocurrency holders.

As such, I’ve always taken the minimum precaution of keeping my coins off third-party accounts, and have always advised others to do the same. But what I couldn’t prepare for was how unnerving being the target of an attack could be regardless of your level of preparation. The hypothetical can become reality in a matter of seconds, and you never truly understand the personal value of putting proper security in place until it’s too late. For those with enough at stake, it can be ruinous. Ultimately none of my funds were compromised by this attack, but others have not been so lucky.

“But not all accounts are created equal for data thieves  —  and the most valuable online accounts to steal are like the ones belonging to Mr. Burniske, who is a cryptocurrency fan. In the few minutes it took to get control of his phone, the virtual currency investor saw his virtual currency password change and its accounts drained of $150,000.” -PYMNTS

The Attack

It started when I received a text message from my cellular service provider alerting me that my SIM card had been “updated.” Included in the text was a number to call if this “update” wasn’t in fact authorized by me. I read this text several minutes after it had been sent, and by the time I called the number provided a minute or two later, my cell service and data were suddenly cut off by what I began realizing must be an attacker. Almost immediately, I was also logged out of my Facebook messenger window right before my eyes. With control of my phone number, my attacker had managed to quickly reset my Facebook password and gain control of the account.

As the reality of what was happening to me sank in, I felt an initial wave of panic. Suddenly, I didn’t know if the years of precautions I had taken amounted to anything at all. I had no idea how robust the attack was, how deep the attacker had penetrated my numerous online accounts or what my first reaction should even be. I momentarily feared the worst. Could my coins be at risk?

I forced several deep breaths. Thankfully my coins were not at risk via a phone, social media or email hijacking. Reminding myself of this eased my fears and allowed me to focus on going on the defensive and taking back control of my accounts as quickly as I could.

Using FaceTime from my laptop, I was able to get a family member to call the number provided by my cellular provider’s text message and initiate the process to eventually retake control of my phone number. Using an old email strictly used as an emergency recovery email for situations such as these, I was also able to lock down my Facebook account and regain control soon after.

What I discovered once I logged back in confirmed that the attacker had specifically targeted me due to my public cryptocurrency involvement. In the brief span of time they controlled my Facebook account, they had sent the same message to several friends of mine also involved in the ecosystem, many of whom I’ve known for years. The messages claimed I had an emergency and needed to borrow several bitcoins or the equivalent value in alternate coins for a day. The attacker was in the middle of sending out many more such messages to even more of my friends when I regained control.

At the end of the day, the damage done to myself was limited to being spooked. Unfortunately, however, at least one of the recipients of my fake Facebook messages was later the target of the same attack. I’ve decided to learn from these events and share those lessons, and hopefully help some avert the worst. First and foremost is eliminating this specific and trivially easy attack vector completely.

How to Stop It Before It Happens

Text message two-factor authentication (2FA) is the default security precaution for most online accounts today, and cellular service providers are woefully unprepared for this reality. It is almost trivially easy for an attacker to contact your service provider and pretend to be you.

In all the cases I’ve personally observed, it began with the attacker identifying an individual likely to have cryptocurrency and contacting their cell provider. They impersonate their target using personal information like social security numbers and home addresses from any number of possible leaks, Equifax being the most obvious and concerning source.

After successfully convincing your cell provider that they are you, they then port your SIM card to a phone they control. This approach is known as a social engineering attack, and with today’s common security default of using text messages for 2FA, they immediately have the keys to the kingdom. With your phone number they can now reset the password to any account you have with text 2FA enabled, including cryptocurrency wallets and accounts.

The minimal action you should take right now to prevent this: Contact your cellular service provider and request restrictions to be placed on your account so that no changes can be made to it without special verification. This can include setting a password on your account or requiring you to physically visit a store with your ID to make any account changes. Call again once this is in place and attempt to change your own SIM card as a test to ensure the restrictions have indeed been put in place and are being properly enforced by your cellular provider.

This simple step means that no matter what information an attacker may have on you, socially engineering a takeover of your SIM card is no longer a trivially simple endeavor. However, this precaution isn’t ironclad, and there’s also a variety of other attacks you can be the target of.

Taking It a Step Further

Black hat actors tend to focus on the low-hanging fruit, which is why the social engineering SIM attack has become so prevalent. But it is by no means the only way to compromise your accounts, and as the low-hanging fruit become harder to find, attackers will move on to these other methods. I highly recommend everyone implement these precautionary steps to further secure yourselves. The upfront investment needed to set up these measures may seem tedious now, but can pay invaluable dividends in the future.

1. If you hold any significant amounts of cryptocurrency, invest in an offline hardware storage solution.

These devices contain your cryptocurrency private keys and can remain completely disconnected from the internet or any computer until you need to make transactions, so that your funds remain totally safe regardless of any of your other devices or accounts being compromised. These devices include OpenDime, TREZOR and Ledger. Even if you do not opt for any of these solutions, at a bare minimum do not store funds on third-party services such as Coinbase or exchanges, especially on any service or wallet that integrates email or a phone number to authorize access to funds.

2. Ditch text messaging 2FA.

Placing verification restrictions on your cellular service account is a big step up in security, but can still be circumvented by an insider or even just a careless customer service rep who doesn’t do their job properly. Text message authorization is also still too incredibly insecure to be relied on in any way, period. Recent research shows that intercepting text messages is a trivial task for someone with the right tools, and many other exploits are likely to be discovered in the future.

The first item on this list will protect your personal funds from theft, but as I learned the hard way your money isn’t the only thing at risk. With access to your social media accounts and emails, an attacker can trick your friends into giving them funds or exposing themselves in other ways. They’ll also obviously have a clear look into all your messaging and file history on those accounts, which can expose you and your social circle even more. Shoring up your 2FA is a big step in preventing this.

Eliminate all of your text messaging–based 2FA and at a minimum replace it with Google Authenticator. However, like storing cryptocurrency, you can take it a step further with a dedicated hardware solution. I highly recommend YubiKeys.

You can configure many major online accounts (not Coinbase yet) to require you to physically insert and activate your YubiKey as your 2FA authorization, eliminating the risk of a remotely compromised phone.

3. Use multiple emails with interlinked recovery options, and use completely different and robust passwords for those emails and other online accounts alike.

Luckily I did not have text messaging 2FA enabled on the email account associated with my Facebook profile; otherwise my attacker could have seized control of that as well. If they did, I have a chain of recovery emails I could have used to regain control of it, all with different passwords. This practice also means that having your password being captured or leaked for any one of your accounts won’t jeopardize all of them.

4. Stay vigilant, stay paranoid.

To quote the Onion Knight, “Safety is never a permanent state of affairs.” Don’t get lazy and begin recycling passwords or leaving funds on Coinbase or other third-party accounts. Be aware of the technology you are using and the tradeoffs you are making or exposure you are generating by doing so. Stay up to date on the latest breaches, exploits and technology. Opt to use end-to-end encrypted messaging services like Signal, Telegram or WhatsApp. Don’t answer calls from strange phone numbers, and use apps like Hiya to filter out known spam numbers to reduce the risk that you do. Ultimately, however, there is no easy fix for security and no list that can guarantee you won’t get hacked.

Make no mistake, there are individuals out there who want to harm you and are actively working to do so. The time needed to reasonably secure yourself can seem tedious and time-consuming up front, but can easily and quickly become a priceless investment as I and many others have learned firsthand.

Op Ed: How Blockchain Technology Could Save Struggling Artists Around the World

artonbc.jpg

To a complete outsider, the worlds of art and cryptocurrency do not appear to be linked. But for content creators of all kinds, blockchain technology provides an ideal solution to preserve intellectual property, create demand and increase value for digital content.

The digital revolution is often blamed for making life harder than ever for artists. We are always hearing stories of artists realizing their work has been ripped off by a major brand or that they are not being paid or credited for the content they create.

However, thanks to blockchains, ownership rights can be restored in favor of artists. The very digital landscape that proves so difficult for artists could well increase the possibility of profits for artists online.

Physical art was one of the first big applications of blockchain technology.

The concept of integrating blockchain technology into the art industry is not untested. Blockchains have already been a part of the physical art world for a few years now as a reliable way to verify creation and ownership details. The application of a trustworthy system of verification like the blockchain to artworks makes perfect sense.

A number of companies are actually already authenticating artwork with blockchain technology, including Verisart in Los Angeles, Tagsmart in London and Ascribe in Berlin. For both collectors and artists, they provide digital certificates of authenticity and provenance records that enable buyers to verify the authenticity of the artwork they purchase while creating an accredited ownership history for the artwork over time.  

What blockchain technology provides is its unmodifiable digital ledger which logs every single digital transaction. More importantly, this ledger is public so everyone can see its history. This means, for example, that you can see that the painting you are interested in has been purchased three times from buyers in London, Madrid and Milan. Because the log is decentralized and cannot be edited, there is no potential for lies or trickery — no one can sell you a fake copy if a digital record of the authentic piece exists.

By allowing records like provenance, authorship and ownership to be unmodifiable, blockchain technology potentially solves the issue of forgeries and thefts in the art world. According to the FBI, billions of dollars worth of art and cultural property go missing every year. Being able to prove and track the ownership of artwork could make it almost impossible to resell stolen artwork in the future.

By increasing trust in the art world, blockchain technology could also help increase the value of art. One important factor in art is scarcity — it is what drives demand. People covet beautiful things: the more unique, the better. The Mona Lisa wouldn’t likely be worth $2 billion if there were 10 originals on the market.

Blockchain technology may pave the way for a robust new market of digital art.

It is no secret that life for digital artists can be difficult. In the music world, for example, physical sales are almost non-existent. Artists earn less than a cent from each time their music is played. At Spotify, the average payout for a stream to labels and publishers is between $0.006 and $0.0084. By the time the label has taken its share, artists receive an estimated $0.001128.

The digital art and design world is arguably just as bad — or worse. While individuals can easily download a music file from a file-sharing website, it is even easier to screenshot or share digital art without any attribution or financial benefit for the artist. As long as people don’t consider digital assets “objects,” digital artists won’t be paid what their work is worth. However, being able to certify the ownership of digital assets through the blockchain could assure the value of digital art and change the behavior that it is okay to swipe art from the web without a thought. People already consume all kinds of creative content on digital screens, be it books, movies, media, or music. The time has come for them to value digital art they can appreciate just as thoroughly on their devices.

A new generation of blockchain-based art collections is bringing the digital art and cryptocurrency worlds together.

For many people, a painting on the wall is worth money; but a digital work of art online has no financial value. A new business model, however, is now emerging for digital art that could alter this perspective.

CryptoPunks by Larva Labs is one known example. The company has created 10,000 computer-generated digital characters, each one unique, with proof of ownership stored on the Ethereum blockchain. Each one is owned by a single person and verified by a smart contract. As the blockchain data is public, you can see exactly which of the characters have been purchased and which remain available. Some people have spent 10 ETH (around $3,000) on the rarest types of CryptoPunks on the secondary market.

Another example is the selling of “Rare Pepes,” crude depictions of the meme often used online as an alt-right symbol. Meme artists previously tried to watermark their memes; nevertheless, they continued to be downloaded and shared. The solution was to use the Counterparty platform, which allows users to make anything into a unique digital token. Now the Pepes can be bought and sold — the rarest costing $11,589 — with RarePepeWallet.com.

This is just the tip of the creative iceberg. Imagine the possibilities with digital art created by actual artists becoming desirable and more valuable. In addition, artists who otherwise would have been forced to use a large-scale centralized company to distribute their work are now able to distribute their work in a decentralized way and receive fair compensation.

Soon, people may begin collecting digital art in the very same way they collect it in its physical form. This may also require a cultural shift in the perception of digital art and its value, but this cultural shift could well be instigated by applying technology, thereby adding financial value and scarcity to digital art. This may well turn out to be a significant boon in the lives of artists all over the world who will be able to profit and take control of their creative output and their intellectual property in a dynamic, budding market.

Decred Adds Atomic Swap Support for Exchange-Free Cryptocurrency Trading

Decred Adds Support for Atomic Swaps for Direct Cryptocurrency Trading Without Exchanges

Decred is announcing support for on-chain atomic swaps, which will allow cryptocurrency holders to trade directly, without having to rely on external exchanges. The cryptocurrencies initially supported are Decred (DCR), Bitcoin (BTC) and Litecoin (LTC).

“Support for on-chain atomic swaps is extremely useful,”Jake Yocom-Piatt, Decred Project Lead said in a statement. “Thanks to the foresight of the Lightning Network authors and developers, and the dedication of our own developers, it is our pleasure to deliver an important capability that has been discussed since the concept of cross-chain atomic transfers was proposed in 2013.”

Users can already begin performing exchanges between DCR, BTC and LTC using tools that the Decred developers have created. The tools are text-based at the moment, but will be integrated into the Decrediton GUI wallet in a future release.

According to the Decred team, this advancement disintermediates the exchange process, allowing for greater market fluency. It also delivers on the market desire for improved interoperability between currencies and the demand for new efficiencies that drive investor value.

"This is the first step in a progression toward high-utility, non-Turing complete smart contracts,” Yocom-Piatt told Bitcoin Magazine. “We look forward to a new generation of greater fluency between projects. It was a pleasure collaborating with the dev teams at Litecoin and Lighting Labs."

The concept of atomic swaps (or atomic cross-chain trading) were first described by Tier Nolan back in 2013. A previous Bitcoin Magazine article provides a step-by-step explanation of a simple example where two users agree to swap agreed amounts of BTC and LTC and use the multisig and time lock features available in both Bitcoin and Litecoin basic scripting to synchronize two transactions on two independent blockchains without having to trust each other.

Yesterday I did an on-chain atomic swap of 1.337 LTC for 2.4066 DCR w/ @_alyp_ of @decredproject. (See txns: https://t.co/BlxU1QBK2U) ⛓️⚛️💱🚀 https://t.co/wPqzdw40Gp

— Charlie Lee (@SatoshiLite) September 20, 2017

It’s worth noting that Lightning Network payment channels, now enabled by SegWit, make atomic swaps more powerful and easier to implement, and permit adding support for off-chain swaps.

“The addition of LN support allows for both on-chain and off-chain atomic swaps, meaning that trustless cross chain exchanges can occur,” noted Yocom-Piatt. “Since supporting LN does not break any existing functionality and only adds to Decred’s capabilities as a system of value storage and transmission, it is a very attractive target for addition to Decred.”

“On-chain atomic swaps are an important step towards enabling peer-to-peer cryptocurrency trading,” said Laolu Osuntokun, Lightning Network Daemon (LND) lead developer. “We are excited for this process to continue with off-chain atomic swaps over the Lightning Network in the near future. By taking this process off-chain, substantial latency and privacy improvements can occur.”

Decred (DCR) describes itself as “digital currency for the people,” completely independent, community funded and community owned. The project wants to build an open and progressive cryptocurrency with a system of community-based governance integrated into its blockchain,  including a hybrid consensus system to ensure that no group can control the flow of transactions or make changes to the currency without the input of the community.

“Decred is Bitcoin as it should have been,” noted crypto-investor Jon Creasy. “Bitcoin would be of the people, for the people. As great an idea as this was, however, Bitcoin soon became controlled by an ‘oligarchy,’ so to speak.”

It’s important to note that some countries, such as China, are attacking cryptocurrency exchanges as the weakest links in the crypto ecosystem. The Decred move shows that, at least for crypto-to-crypto trading (for example, exchanging bitcoin for litecoin), it’s perfectly possible to operate without exchanges. However, it doesn’t solve the problem of crypto-to-fiat and fiat-to-crypto trading, which is arguably of top concern for cryptocurrency users.

Reflecting gold’s historical repute as a scarce and valued resource, Bitcoin has become known in many investment circles as “digital gold.” With its unprecedented rise, Bitcoin’s worth is now estimated to be about twice that of an ounce of physical gold.

On August 7, 2017, the startup GoldMint was launched with the intent of ushering in a new digital era of gold as a store of value. This project aims to provide a unique set of gold ownership solutions for cryptocurrency investors and enthusiasts worldwide. It is holding an initial coin offering (ICO) that starts in less than 12 hours. 

The GoldMint project reaffirms the notion that physical gold is a respected method of payment and wealth preservation, all tied to its value and scarcity. Gold ownership, however, requires expensive security, safekeeping and insurance. GoldMint’s innovative approach seeks to address these inherent issues.

GoldMint purchases, sells and repurchases their native digital asset called

“GOLD,” which is 100 percent backed by physical gold. It features an Exchange Traded Fund (ETF) which can be utilized as a payment and investment tool for both companies and individuals in hedging risk.

Capitalizing off of the inherent advantages of its physical counterpart,

GOLD tokens offer a stable, transparent, non-volatile means of buffering one’s crypto portfolio from wild market swings. Here, GoldMint is committed to ensuring that GOLD delivers consistent value through paper assets like ETFs and futures as well as through physical assets. Moreover, GOLD owners will be able to use their tokens to secure guarantees, loans and escrow services, all at a modest 5 percent purchase and 3 percent sale fee.

GoldMint will also deliver a utility token known as “MNT” to facilitate operations, implement smart contracts and incentivize block creation and transaction confirmation.

During the early stages of this project, MNT will be sold and distributed on the Ethereum blockchain. After the MNT distribution has taken place, Goldmint will launch its own Graphene -based Proof-of-Stake (PoS) blockchain that offers a safer, more productive and faster experience.

Minting the Blockchain

GoldMint utilizes a blockchain ledger to execute trades, loans and investments for profit. The following are what make the GOLD crypto asset unique:

  • 100 percent information transparency relative to all GoldMint GOLD. The company discloses its gold reserves, fostering the opportunity to buy back GOLD at its current trading price.
  • GoldMint utilizes the decentralized blockchain for smart contracts and for its crypto assets.
  • ETFs are used for liquidity and elasticity facilitating gold trades which are far faster than those of physical gold.
  • Secured loans can be leveraged with GOLD, like jewelry or coins. GoldMint assists in the storage of this collateral through its unique Custody Bot, a blockchain-connected robot used for inspection, temporary and long-term storage and the transfer of physical gold, jewelry, coins or gold bullion.
  • Members have the ability to earn passive income as the market price of GOLD rises.
  • An option which allows for the buyback of GOLD for fiat according to the current price of GOLD.
  • A fast and efficient user registration and identification system.

To support merchants and developers, GoldMint is in the process of releasing an application programming interface (API) for the development of third-party apps and other interfaces. Use of this API will allow online stores to accept GOLD as a payment method, enable loans to be secured by banks and provide access to services such as escrow accounts and financial guarantees.

The Goldmint Team

Goldmint is led by CEO Dmitry Plutschevsky, who co-founded Lot-Zoloto — a gold trading company based in Russia with trading transactions totaling $100 million in 2017 — with former banker Konstantin Romanov. Serg Umansky, head of portfolio management at Whiteridge Investment Funds, Alex Butmanov, managing partner at DTI and Julian Zegelman, managing partner at Velton Zegelman, are among the advisors of the company

GoldMint founders predict that its unique value proposition will disrupt the billion-dollar gold market, allowing GoldMint to establish itself as a market leader in the coming cryptocurrency revolution.

Bitcoin Price Analysis: Amid Continuing China Rumors, BTC Fails to Break Key Resistance

China BTC price.jpg

When it rains, it pours. Last week, news began to hit the crypto community that China was taking harsh measures to reign in their various cryptocurrency exchanges. Several exchanges closed down and others were given a deadline to properly cease trading operations. This news came hard on the heels of recent directives that banned ICOs in China, leading to dramatic drops in cryptocurreny prices across the board.

After this latest news settled, bitcoin managed to slightly rally before topping out around $4100. However, early this week, rumors began to circulate that executives associated with Chinese exchanges are being prohibited from leaving China. At the time of this article, BTC-USD is sitting just at $3900 and is showing signs of further pullback:

Figure_1 (8).JPGFigure 1: BTC-USD, 12-Hour Candles, GDAX, Macro Fibonacci Retracement Values

The figure above shows the whole, macro bull run from the $1700s. One important feature of the trend shown above is the 61% retracement down to the $2900s. The retracement down to such a low value shows that sell pressure is very strong in the current market and hints toward bullish exhaustion within the macro trend. Another key feature to note is the following:

Figure_2 (8).JPGFigure 2: BTC-USD, 2-Hour Candles, GDAX, Failed 100% Retracement

An important test of this rally was the 100% retracement of the bear run, post-China news. Sitting just below the 23% Fibonacci Retracement lies the bear run. The test of the 100% retracement is important because that resistance line marks a strong shift in market sentiment. A failure to break through those values shows that, even though there was a strong rally, the market is still bearish in nature and is likely to continue.

Figure 2 also shows several tests and rejections of the 2-Hour 200 EMA (Exponential Moving Average). The 200 EMA is a common tool used among traders to objectively view the state of the market compared to the prior trends. A trend existing below the 200 EMA is bearish in nature, and trends that show support on top of the 200 EMA are bullish in nature.

At the time of this article, the BTC-USD is displaying two failed tests of key resistance levels and its showing little sign of upward pressure. Currently, the trend is sandwiched between the 200 EMA and the 50 EMA. Both moving averages can used in conjunction to gauge just how strong the market is. Like the 200 EMA, the 50 EMA shows short-term bullish and bearish trends relative to the EMA line: Trends above are showing bullish traits, and trends below are showing bearish traits.

Right now, we are in the middle of a crucial test of both support and resistance lines as the market decides where it will go next. A break below the 50 EMA will ultimate show the long-term bearish intent of the market and will lead to tests of the low support values:

Figure_3 (9).JPGFigure 3: BTC-USD, 1-Hour Candles, GDAX, Support Levels for Current Rally

At the moment, BTC-USD is making its third test of the current rally’s 23% retracement values. A break below this line will have bitcoin testing the macro 38% retracement values in the $3700s. If bitcoin manages to break the 38% retracement values somehow, there will be strong support around the $3400s as the 50% macro Fibonacci Retracement values (shown in Figure 1) have historic significance and support.

If bitcoin is going to see any significant price growth within this rally, it will have to pick up some major buy volume and break through very strong, historic resistance values. It’s extremely unlikely that, given its repeated failures to break resistance and the inherent bearish news looming over the Bitcoin community, BTC-USD will shove to new highs without strongly testing lower macro support.

Summary:

  1. BTC-USD had a strong rally, but ultimately topped out around $4100.

  2. At the moment, BTC-USD is testing macro support levels and shows very little, significant upward strength.

  3. Should we break support in the $3900s, we can expect a test of the macro 38% Fibonacci Retracement values in the $3700s.

Uncertainty Dominates as China Continues to Clamp Down on Cryptocurrencies

Uncertainty Dominates as China Clamps Down on Cryptocurrency

China is clamping down on cryptocurrency, that much is clear. But while the developing story dominates headlines, a notable trend is the lack of official information. Chinese officials seem to systematically decline requests for comments, local sources are willing to provide information on condition of anonymity only, while leaked documents remain unverified.

Despite this lack of clarity, here’s what’s known so far.

Effects on Trading

The most important thing we know for sure is that Chinese bitcoin exchanges will be closing down, or at least exiting China.

BTCC — the oldest bitcoin exchange in the world — was the first exchange to announce they’d be closing shop within the Asian country, by the end of this month. The exchange cited guidelines published by the Chinese central bank (the People’s Bank of China; PBOC), which initially appeared to only affect ICOs, as its reason for closing down.

Other exchanges quickly followed BTCC's lead. ViaBTC and Yunbi both announced that they’d be ceasing operations by the end of this month. Huobi and OKCoin, the two other major Chinese exchanges, announced they would be shutting down too, though not until the end of October. And BitKan, a big over-the-counter (OTC) trading service rather than an order-book exchange, announced it would be shutting down as well.

While the cited guidelines initially did not seem to concern bitcoin, it is likely that Chinese officials have made it clear through separate channels that they do apply to the cryptocurrency. Bloomberg (among others) reports that exchange operators decided to close down after in-person meetings with PBOC officials, and the Wall Street Journal reports — based on anonymous sources — that the PBOC has prepared a set of “draft instructions” that would ban cryptocurrency trading altogether. These draft instructions have also been leaked (translation) but have so far not been verified for authenticity.

The content of the leaked documents is also consistent with warnings issued by a Chinese quasi-regulatory body — the National Internet Finance Association of China (NIFA) — regarding cryptocurrency trading, published shortly before exchanges announced that they would be shutting down.

According to the NIFA, Bitcoin exchanges lack “legal basis” to operate in the country. Additionally, NIFA official Li Lihui told a technology conference in Shanghai on Friday that a goal of China’s monetary regulation is to ensure that “the source and destination of every piece of money can be tracked.”

The Status of Bitcoin

As far as official statements go, Bitcoin itself is not banned in China. Owning, using, and — most importantly — mining bitcoin should technically not be affected by the published guidelines.

However, more unverified reports (translation) consistent with reporting from the Wall Street Journal, claim that Bitcoin itself will be blocked by the so-called “great firewall of China.” Specifically, seed addresses, which help to bootstrap any new Bitcoin node, and Bitcoin blocks, necessary to construct the blockchain, would be filtered from internet traffic into China, using deep packet inspection.

Additionally, major foreign Bitcoin exchanges like Coinbase, Bitfinex and LocalBitcoins would be added to the list of banned domains, which already includes sites like Google and Facebook. And even private trading of cryptocurrency arranged through chat-apps like Telegram and WeChat, for example, could fall under scrutiny, according to the Wall Street Journal.

This much stricter stance on Bitcoin, beyond just exchanges but also concerning Bitcoin itself, seem consistent with comments from PBOC Counselor Sheng Songcheng, as reported by local news sources like Shanghai Securities News. Songcheng was quoted to have said that Bitcoin poses a challenge to China, mentioning money laundering and its potential to curb the nation’s economic policy.

Furthermore, very recent reports indicate that cryptocurrency exchange operators are currently not allowed to leave Beijing. Local news outlet BJ News writes:

“[According to] a number of informed sources, the current special currency trading platform executives and so on are not allowed to leave Beijing, [in order] to cooperate with the investigation. In accordance with regulatory requirements, the trading platform shareholders, the actual controller, executives, financial executives [must] fully cooperate with the relevant work in the clean-up period in Beijing.” (Rough translation.)

What This Means…

Trading bitcoin via dedicated exchange platforms in China is off the table for now — that is clear.

But it’s not yet clear how successful a full Chinese Bitcoin blockade could be. It would technically only require a single Bitcoin block of a maximum of four megabytes to make it into China about once every 10 minutes, potentially even through satellite, for the entire country to be able to access the blockchain. As such, banning individual Chinese citizens from owning and using bitcoin might prove difficult, even if exchange platforms close down.

Perhaps an even more important question is what will happen to Bitcoin mining: It’s likely that most of Bitcoin’s hash power is currently situated in the Asian country. While miners should able to connect to the rest of the world, according to ViaBTC CEO Haipo Yang, it’s unclear if this connection will be allowed for much longer. If Chinese authorities indeed intend to ban Bitcoin from the country entirely, some Bitcoin mining operations — both mining pools and hash power data centers — will be easy targets to shut down.

On the other hand, this is not the first time that fears of China “banning Bitcoin” have been raised. In the past, such concerns have simply been a prelude to stricter regulations by local authorities.

It has been suggested by Bitmain CEO Jihan Wu, perhaps a bit optimistically, that exchanges will simply require a new license to continue operation. Similarly, it’s been speculated that the PBOC may introduce a national digital currency as a sort of gateway to cryptocurrency: This would allow the central bank to better track the flow of funds in and out of bitcoin in order to counter money laundering and capital flight.

Then again, it could make more sense to introduce such a national digital currency as a substitute for Bitcoin, once Bitcoin is effectively banned, as suggested by ZeroHedge.

For now, uncertainty prevails.

Bitcoin Exchange bitFlyer Hopes to Win Big With the Japanese Bankers Association

bitFlyer.jpg

While China tightens its grip on its cryptocurrency community, Japan is openly embracing cryptocurrencies and blockchain technology, legalizing bitcoin, and encouraging and funding blockchain research.

Even Japan’s banks are onboard, working collaboratively to develop a blockchain platform specifically for the financial sector. With its 120 member banks, the Japanese Bankers Association (JBA) is creating a Collaborative Blockchain Platform and is actively looking for a company to supply its blockchain technology on an ongoing basis.

Experimenting with the Collaborative Blockchain Platform, the JBA will initially determine which financial services best lend themselves to the new platform, likely including settlement/transfer services, know-your-customer (KYC) systems and financial infrastructure such as their Zengin System and Densai Net System.

Japanese bitcoin exchange bitFlyer is stepping up to the plate to take on tech giants including Fujitsu, Hitachi and NTT Data to be the supplier of the blockchain platform that will be used by Japan’s banks.

Although it is one of the largest cryptocurrency and blockchain startups in Japan, the Tokyo-based bitFlyer has its work cut out for it if it wants to upset these three corporate heavyweights and win the right to supply the bankers with a blockchain platform using its miyabi technology.

The company’s COO Bartek Ringwelski told Bitcoin Magazine:

“bitFlyer is the only startup in the event, and we have only raised $36mm since 2014, but we have deep expertise in blockchain technology through our virtual currency exchange (the largest in the world by volume, including margin trading) and our ‘miyabi’ product.”

By way of comparison, Hitachi posted $83 billion in revenue in 2016, Fujitsu posted $47 billion on 2015 and NTT Data posted $15 billion in 2016.

Acknowledging a sea change in Japan’s attitude to cryptocurrency, Ringwelski noted that Japan is actively encouraging and supporting both cryptocurrencies and blockchain technology:

“Japan is emerging as a leader in blockchain adoption. Japanese consumers are embracing virtual currencies, regulators are proactive, and banks are recognizing the power that blockchain, and specifically miyabi, can bring to the financial infrastructure.”

Miyabi Blockchain Technology

The name “miyabi” was first coined between the 9th to 12th centuries by Japanese aristocrats to refer to the theme of elegance and refinement.

According to Ringwelski, bitFlyer’s miyabi blockchain platform is the fastest in the world:

“Based on our research, ‘miyabi’ is the fastest enterprise-grade blockchain technology, delivering 1,500 - 2,000 transactions per second on average, and in some cases, even faster,” Ringwelski said.

Their processing speed of 1,500 to 2,000 transactions per second compares with Bitcoin’s two transactions per second and Ethereum’s seven transactions per second. They also estimate that among the other three competing companies, the maximum speed to beat is 1,000 transactions per second.

When it launched the competition, the JBA made it clear that security and immutability were their first priority. In their view, only a private, permissioned blockchain could satisfy this requirement.

Going Global

BitFlyer’s CEO Yuzo Kano has said he wants the company to go global in the near future and will start by expanding to the U.S. market this fall, initially offering bitcoin trading but expanding to other cryptocurrencies within the next year. The company says it has received approval to start trading from 34 U.S. states.

In the meantime, Ringwelski says that they are eagerly awaiting the decision of the JBA:

"The partner ultimately chosen by the JBA will stand to become part of the core Japanese banking infrastructure — it would be a big deal. Beyond the value of gaining the JBA as a new customer, securing a JBA contract would help spread miyabi to new enterprise blockchain applications and customers worldwide."

Investors in bitFlyer include SMBC Venture Capital, Mizuho Capital, Dai-ichi Life Insurance, Mitsubishi UFJ Capital, Mitsui Sumitomo Insurance Venture Capital, Recruit Strategic Partners, Dentsu Digital Holdings, SBI Investment, GMO Venture Partners, QUICK and Venture Labo Investment.
