Bitcoiner Faces Charges After Selling BTC to an Undercover Cop

Bitcoiner Faces Charges After Selling BTC to an Undercover Cop

On February 9, 2018, officials from U.S. Immigration and Customs Enforcement (ICE), the investigative arm of the Department of Homeland Security, arrested Morgan Rockcoons (aka “Morgan Rockwell” or “Metaballo”), CEO at Bitcoin, Inc. and an entrepreneur behind several other bitcoin startups, at his home in Las Vegas, Nevada.

Rockcoons was charged with money laundering and operating an unlicensed money transmitting business, according to court records.

According to those same records, in Southern California, between December 30, 2016 and January 8, 2017, Rockcoons allegedly exchanged around 10 bitcoin (worth around $9,200, at the time) for $14,500 in cash with an undercover law officer. That officer allegedly told Rockcoons in advance that the cash came from the manufacture and distribution of “hash oil,” which contains tetrahydrocannabinol, a controlled substance at the federal level.

Money laundering happens when a person takes ill-gotten money and turns it into “clean” money that cannot easily be tracked back to its source. Thus, if Rockcoons knew the cash was dirty, but traded it for bitcoin anyway, that would constitute money laundering.

Rockcoons was also allegedly operating an unlicensed money-transmitting business in Southern  California “from a date unknown” through August 30, 2017. Money transmitters are required to register with the Financial Crimes Enforcement Network (FinCEN).

The warrant for the arrest was issued by the Chief Magistrate for the Southern District of California on November 8, 2017, which indicates it may have taken authorities three months to track down Rockcoons, possibly because he moved out of the original jurisdiction.  

A Different Story

In private messages with Bitcoin Magazine and a series of public tweets, Rockcoons, who is actively seeking donations to pay for his legal fees, which he expects to be between $150,000 - $300,000, tells a different story than what is reflected in court records.

Where the court document says that the the cash given to him was already dirty, he claims that bitcoin he sold to the buyer became dirty after it left his hands.

“Someone bought a machine that makes cannabis oil with the BTC they purchased from me,” he said to Bitcoin Magazine. “I guess I'm not allowed to sell Bitcoin as a U.S. citizen for cash especially if [responsibility for] what people do with that money lies on me.”

In communication with Bitcoin Magazine, Rockcoons said that the buyer told him via text message that the bitcoins would be used to buy a “medical hash machine.”

He added, “Buying equipment in California is not illegal especially medical equipment in a medical State that's been a medical state for 25 years. [A] controlled substance does not have anything to do with the equipment because CBD oil can be extracted from Cannabis and that doesn't have anything to do with Tetra Hydro cannabinol.”

Both Rockcoons’ tweets and his subsequent communication with Bitcoin Magazine seemed to imply, initially, that he had no idea he was selling bitcoin to a law enforcement officer.

On Friday Feb 9, I was arrested in my home by Department Of Homeland Security over a #Bitcoin transaction from nov 2016 and am released under a personal recognizance bond. I am being charged with:

Asset Forfeit pic.twitter.com/5kINtbxH17

— Morgan (@NODEfather) February 14, 2018

According to Rockcoons, the exchange took place in November 2016 (not the first week of January, as listed in court records) while he was living in Northern California (not Southern California, as the records state).

Rockcoons said the buyer found him through LocalBitcoins, an online platform that facilitates direct selling of bitcoin. A user can register as a seller on the platform and be contacted by interested parties. Transactions are done in person or via online banking.

Rockcoons claimed on Twitter that he received $9,200 for the bitcoin, though court records allege the law officer gave him $14,500. Rockoons later told Bitcoin Magazine that he specified to the buyer he wanted less than $10,000, but the buyer insisted on sending him $14,500.

“They tried to entrap me,” Rockcoons told Bitcoin Magazine. “I asked for only less than $10,000, they sent me $14500 [or] refused to send anything and then I sent under $10,000 [worth of bitcoin] to follow the law.”


After agreeing to the terms of the sale online, Rockcoons claims he received a cash payment. He described this payment, in his communication with Bitcoin Magazine, as being received in an envelope sent through the mail. He has not replied to requests for clarification as to whether or not he met with the buyer in person, though he did say that he and the buyer communicated via text messages.


At the time of the exchange, he was camping in the Mendocino National Forest, where he was living in a tent and working on a new project, a voice-operated Bitcoin wallet. Rockcoons said he had been living in the Northern California wilderness since 2015; however, fire and floods were making it increasingly difficult to survive in the area. After another fire ravaged the land, he said he needed cash for evacuation emergencies.

“I was living like a mountain man, so I didn’t really need money but eventually I needed to buy food so I decided to sell some coin; when someone asked me to buy some I usually just always turn it down but I needed cash to eat,” he told Bitcoin Magazine.

He claims the fires were what eventually forced him to move back to Nevada.

Time in Jail

After his arrest in Las Vegas on Friday, February 9, 2018, Rockcoons was locked up over the weekend in Henderson Detention Center in Clark County, Nevada, for three days. He pled not guilty at a Federal Court hearing on February 12, 2018, and was then sent to Clark County Detention Center for two more days for an unrelated charge of failure to appear on a traffic ticket.

“I was in jail for five days with some of the scariest humans on Earth,” he said. “But I [taught] most of them how Bitcoin works, so it was worth it.”   

In his series of ongoing tweets since his release from jail on February 14, 2018, Rockcoons has been portraying the charges against him as an attack on Bitcoin.

It's not my mess, it's everyone on Earths [sic] battle now or you can kiss your access to BTC goodbye,” he wrote in one tweet.

This is a attempt to redefine the regulation and the law,” he told Bitcoin Magazine.

“Bitcoin is my religion,” he wrote in another tweet. “God says I can use bitcoin everyday.”

Rockcoons is also claiming he was targeted due to his relationship with the state and the federal government and his Bitcoin-related startups.

Because of my relationship with the State & Federal Government as well as my relationship with the US military, because of my involvement in creating @BitSwitchIO at @BitcoinKinetics and possibly the opportunity to pull a @CharlieShrem case in California to get the west coast.

— Morgan (@NODEfather) February 14, 2018

He is looking to others to join the “battle” with him, and he is even asking the the Bitcoin Foundation, a non-profit organization that supports Bitcoin adoption and education, to cover 15 bitcoin (worth around $150,000) of his legal costs.

“It seems to me the Bitcoin Foundation has been absent from the Bitcoin Community during troubling times, this would be a good opportunity to show face and show the community that you're here for all of us," he tweeted.


Rockcoons’ arraignment is on February 22, 2018 at the San Diego Superior Court in California. He has hired Las Vegas criminal attorneys David Chesnoff and Richard Schonfeld to represent him. He says he plans to pay them in bitcoin.


(Note: Shortly before publishing this article, Rockcoons blocked the writer from viewing his Twitter account.)

HashChain Technology Acquires Blockchain Company NODE40

HashChain Mining Operation Acquires NODE40 Blockchain Technology Company

HashChain Technology Inc. (HashChain) has acquired the blockchain technology company NODE40 for $8 million USD and 3,144,134 common shares of stock in HashChain (TSXV: KASH) (OTCQB: HSSHF).

HashChain is a Canadian-based crypto-mining company that currently operates 100 Dash mining rigs and is in the process of setting up nearly 4,000 more to mine bitcoin. By locating in Canada, they are able to take advantage of both the very low electrical rates for power and the cool climate for data center cooling.

Having recently gone public on the TSX Venture Exchange, the company was looking to diversify their business beyond crypto-mining and have now acquired NODE40, a company that develops Software as a Service (SaaS) products related to cryptocurrency.

HashChain CEO and Founder Patrick Gray said, “The acquisition of the NODE40 Business is an important next step of creating a global blockchain technology company."

On the hardware and mining side, NODE40 runs a managed service for running your own Dash masternode. Masternodes get paid 45 percent of the monthly block reward as incentive for providing services to the network.

On the software side, NODE40 provides the SaaS product NODE40 Balance (Balance), which determines accurate valuations for each input/output involved in a user’s transaction by using cryptocurrency transaction history and analyzing the blockchain. Once a value is assigned to each transaction, then Balance will report the users’ current total asset value, income and any realized gains or loses.

"Cryptocurrency accounting and reporting for tax purposes is a major concern in the industry at the moment,” said Gray. “The recent Coinbase subpoena from the IRS highlights the significant need for the software developed by NODE40."

The acquisition was finalized on February 15, 2018.

Sidechains: Why These Researchers Think They Solved a Key Piece of the Puzzle

Sidechains and Why These Researchers Think They Solved a Key Piece of the Puzzle

New blockchains are born all the time. Bitcoin was the lone blockchain for years, but now there are hundreds. The problem is, if you want to use the features offered on another blockchain, you have to buy the tokens for that other blockchain.

But all that may soon change. One developing technology called sidechains promises to make it easier to move tokens across blockchains and, as a result, open the doors to a world of possibilities, including building bridges to the legacy financial systems of banks.

In October 2017, Aggelos Kiayias, professor at the University of Edinburgh and chief scientist at blockchain research and development company IOHK; Andrew Miller, professor at the University of Illinois at Urbana-Champaign; and Dionysis Zindros, researcher at the University of Athens, released the paper “Non-Interactive Proofs of Proof-of-Work” (NiPoPoW), introducing a critical piece to the sidechains puzzle that had been missing for three years. This is the story of how they got there.

But, first, what exactly is a sidechain?    

Same Coin, Different Blockchain

A sidechain is a technology that allows you to move your tokens from one blockchain to another, use them on that other blockchain and then move them back at a later point in time, without the need for a third party.  

In the past, the parent blockchain has typically been Bitcoin, but a parent chain could be any blockchain. Also, when a token moves to another blockchain, it should maintain its same value. In other words, a bitcoin on an Ethereum sidechain would remain a bitcoin.  

The biggest advantage of sidechains is that they would allow users to access a host of new services. For instance, you could move bitcoin to another blockchain to take advantage of privacy features, faster transaction speeds and smart contracts.  

Sidechains have other uses, too. A sidechain could offer a more secure way to upgrade a protocol, or it could serve as a type of security firewall, so that in the event of a catastrophic disaster on a sidechain, the main chain would remain unaffected. “It is a kind of limited liability,” said Zindros in a video explaining how the technology works.

Finally, if banks were to create their own private blockchain networks, sidechains could enable communications with those networks, allowing users to issue and track shares, bonds and other assets.

Early Conversations

Early dialogue about sidechains first appeared in Bitcoin chat rooms around 2012, when Bitcoin Core developers were thinking of ways to safely upgrade the Bitcoin protocol.

One idea was for a “one-way peg,” where users could move bitcoin to a separate blockchain to test out a new client; however, once those assets were moved, they could not be moved back to the main chain.  

“I was thinking of this as a software engineering tool that could be used to make widespread changes,” Adam Back, now CEO at blockchain development company Blockstream, said in an interview with Bitcoin Magazine. “You could say, we are going to make a new version [of Bitcoin], and we think it will be ready in a year, but in the meantime, you can opt in early and test it.”

According to Back, sometime in the following year, on the Bitcoin IRC channel, Bitcoin Core developer Greg Maxwell suggested an idea for a “two-way peg,” where value could be transferred to the alternative chain and then back to Bitcoin at a later point.

A two-way peg addressed another growing concern at the time. Alternative coins, like Litecoin and Namecoin, were becoming increasingly popular. The fear was these “altcoins” would dilute the value of bitcoin. It made sense, Bitcoin Core developers thought, to keep bitcoin as a type of reserve currency, and relegate new features to sidechains. That way, “if you wanted to use a different feature, you wouldn’t have to buy a speculative asset,” said Back.

To turn the concept of sidechains into a reality, Back along with Maxwell and a few other Bitcoin Core developers formed Blockstream in 2014. In October that year, the group released “Enabling Blockchain Innovations with Pegged Sidechains,” a paper describing sidechains at a high level. Miller appears as a co-author on that paper as well.

How Sidechains Work

One important component of sidechains is a simplified payment verification (SPV) proof that shows that tokens have been locked up on one chain so validators can safely unlock an equivalent value on the alternative chain. But to work for sidechains, an SPV proof has to be small enough to fit into a single coinbase transaction, the transaction that rewards a miner with new coins. (Not to be confused with the company Coinbase.)

At the time the Blockstream researchers released their paper, they knew they needed a compressed SPV proof to get sidechains to work, but they had not yet developed the cryptography behind it. So they outlined general, high-level ideas.

The Blockstream paper describes two types of two-way pegs: a symmetric two-way peg, where both chains are independent with their own mining; and an asymmetric two-way peg, where sidechain miners are full validators of the parent chain.

In a symmetric two-way peg, a user sends her bitcoins to a special address. Doing so locks up the funds on the Bitcoin blockchain. That output remains locked for a contest period of maybe six blocks (one hour) to confirm the transaction has gone through, and then an SPV proof is created to send to the sidechain.

At that point, a corresponding transaction appears on the sidechain with the SPV proof, verifying that money has been locked up on the Bitcoin blockchain, and then coins with the same value of account are unlocked on the sidechain.

Coins are spent and change hands and, at a later point, are sent back to the main chain. When the coins are returned to the main chain, the process repeats. They are sent to a locked output on the sidechain, a waiting period goes by, and an SPV proof is created and sent back to the main blockchain to unlock coins on the main chain.  

In an asymmetric two-way peg, the process is slightly different. The transfer from the parent chain to the sidechain does not require an SPV proof, because validators on the sidechain are also aware of the state of the parent chain. An SPV proof is still needed, however, when the coins are returned to the parent chain.

Search for a Compact Proof

In a sidechain, a compact SPV proof needs to contain a compressed version of all the block headers in the chain where funds are locked up from the genesis block through the contest period, as well as transaction data and some other data. In this way, an SPV proof can also be thought of as a “proof of proof-of-work” for a particular output.

Inspiration for the compact SPV proof comes from a linked-list-like structure known as a “skip list” developed 25 years ago. In applying this structure to a compact SPV proof, the trick was in finding a way to skip block headers while still maintaining a high level of security so that an adversary would not be able to fake a proof.

In working through the problem, Blockstream showed an early draft of its sidechains paper to Miller, who had been mulling over compact SPVs for a few years already.

In August 2012, in a post on a BitcoinTalk forum titled “The High-Value-Hash Highway,” Miller described an idea for a “merkle skip list” that a Bitcoin light client could use to quickly determine the longest chain and begin using it. In that post, he described the significance of the data structure as “absolutely staggering.”

When Miller read through the Blockstream draft, he spotted a vulnerability in the compact SPV proof described in the paper. Discussions ensued, but they “couldn’t find a way to solve that problem without compromising efficiency,” Miller said.

Miller’s non-trivial contributions to the Blockstream paper ended up being a few paragraphs in Appendix B that describe the challenges in creating a compact SPV proof.

It should “be possible to greatly compress a list of headers while still proving the same amount of work,” the section reads, but “optimising these tradeoffs and formalising the security guarantees is out of scope for this paper and the topic of ongoing work.”

That ongoing work remained stuck for three years.

Making It Non-interactive

During that ensuing time, researchers at IOHK began taking a more serious interest in sidechains. Plans were taking shape for Cardano, a new proof-of-stake blockchain that IOHK had been contracted to build.

Cardano would consist of two layers: a settlement layer, launched in September 2017, where the money supply would be kept, and a smart contract layer. Those two layers would be two sidechain-enabled blockchains. In this way, the settlement could remain simple and secure from any attacks that might occur on the smart contract layer. But if IOHK was to get Cardano to work as intended, it needed to solve sidechains.

In February 2016, Kiayias, then a professor at the University of Athens, and two of his students, Nikolaos Lamprou and Aikaterini-Panagiota Stouka, released “Proofs of Proofs of Work with Sublinear Complexity” (PoPoW).

The paper was the first to formally address a compact SPV proof. Only, the proof described in the paper was interactive; whereas, to work for sidechains, it needed to be non-interactive.

In an interactive proof, the prover and the verifier enter into a back-and-forth conversation, meaning there could be more than one round of messaging. In contrast, a non-interactive proof would be a simple, short string of text that would fit neatly into a single transaction on the blockchain.

The PoPoW paper was presented at BITCOIN’16, a workshop affiliated with the International Financial Cryptography Association’s (IFCA) Financial Cryptography and Data Security conference. Miller, who was at the conference, approached Kiayias and shared an idea for making the protocol non-interactive.

It was a “nice observation,” Kiayias told Bitcoin Magazine, but making the proof secure was “not obvious at all” and would require significant work.

Zindros, who had just started working on his PhD under Kiayias, was also at the conference, and he needed a topic for his thesis. Kiayias saw a good fit, “so we pressed on, the three of us, and adapted the PoPoW protocol and its proof of security to the non-interactive setting,” Kiayias said.

In October 2016, Kiayias officially joined IOHK, and a year later, Kiayias, Miller and Zindros released “Non-Interactive Proofs of Proof-of-Work,” introducing a compact SPV proof five years after sidechains had first been talked about on Bitcoin forums.

“If it were interactive, I don’t know if it would have worked; with a non-interactive proof, it is really smooth,” Zindros told Bitcoin Magazine.

More Work to Be Done

Even with NiPoPoW, sidechains are still not fully specified. Several questions remain, including, how small can the proofs be made? After a transaction is locked up on one chain, how much time needs to pass before it can be spent on the other? And, will it be possible to move a token from a sidechain directly to another sidechain?

“A lot of theory still needs to be defined,” IOHK CEO Charles Hoskinson said in speaking to Bitcoin Magazine.

Also, while NiPoPoW is designed to work for proof-of-work blockchains, some believe that if blockchains are to take their place in the world on a grand scale, the future rests in proof-of-stake protocols like Ouroboros, Algorand or Snow White, which promise to be more energy-efficient than Bitcoin.

In particular, if Cardano, which is based on Ouroboros, is to work according to plan, IOHK researchers still need to discover a non-interactive proof of proof-of-stake (NiPoPoS).

Hoskinson is confident. “We can definitely do that,” he said. “We can definitely have a NiPoPoS. The question is how many megabytes or kilobytes is it going to be? Can we bring it down to 100 KB? That is really the question.”

CFTC Advisory Committee Recommends Creation of Virtual Currency Subcommittee

CFTC Advisory Committee Recommends the Creation of a Virtual Currency Subcommittee

On Wednesday, the U.S. Commodity Futures Trading Committee’s (CFTC) Technical Advisory Committee (TAC) held a public meeting at its Washington, D.C., headquarters. During the meeting, members of the Bitcoin and cryptoasset industry shared information regarding this emerging market and offered guidance on how the CFTC may approach regulating the space in 2018.

Multiple participants in the public hearing made comments to differentiate between different types of cryptoassets and their associated technologies.

Potential regulation around cryptoasset exchanges was also discussed as a potential area for further regulation, as has been noted by regulators worldwide over the past few months.

By the end of the portion of the public hearing dedicated to virtual currencies, the TAC voted unanimously to recommend that the CFTC create a subcommittee for this new asset class.

Differentiating Between Different Types of Cryptoassets

One of the key points made by those who were invited to speak about the cryptoasset industry was that all of these tokens or coins should not necessarily be treated equally. For example, during his opening remarks, Coin Center Executive Director Jerry Brito discussed the differences between traditional cryptocurrencies, such as bitcoin, and initial coin offerings (ICOs).

“Cryptocurrencies like bitcoin are commodities, of course, as the SEC has previously [said].  Questions remain however about the borders [around] these categories and about how one can responsibly share tokens to future investors,” noted Brito.

Special Counsel Gary DeWaal of Katten Muchin Rosenman LLP went on to discuss the often-mentioned Howey Test and how it helps determine which types of tokens are securities under U.S. law. In DeWaal’s view, the CFTC could offer assistance in differentiating between commodities and securities in the cryptoasset market.

“Ultimately there has to be some clarification. The distinction between a commodity, the distinction between a security, may seem (from a common sense perspective) clear, but there are very, very important issues around those that I think this committee could very much [help clarify],” said DeWaal.

Notably, DeWaal also pointed out that cryptoassets are “critical” to decentralized ledgers.

“They are the mechanism in proof-of-work blockchains where miners are rewarded: In proof-of-state blockchains where fees are paid, these are the ways you incentivize folks to keep the system together. If you’re only talking about centralized ledgers, sure, you don’t need to worry about coins,” DeWaal added.

Regulation of Cryptoasset Exchanges

RGM Advisors’ chief executive, Richard Gorelick, also made an appearance at the CFTC’s public hearing, and he focused on the market structure of cryptoassets during his brief opening presentation (PDF). Gorelick was one of the only people in the room who referred to the subject at hand in terms of “cryptoassets” rather than “cryptocurrencies” or “virtual currencies.”

One of the key areas of focus for Gorelick during his presentation was the problems associated with current cryptoasset exchanges. More specifically, Gorelick discussed the issues associated with connectivity of liquidity between global exchanges.

“Generally speaking, I think trading on these [exchanges] can be challenging, particularly if your goal is to trade across multiple spot exchanges. It’s difficult to weave liquidity across exchanges and jurisdictions due to a number of factors,” noted Gorelick.

Some of the factors limiting the movement of funds between various exchanges pointed out by Gorelick include:

  • Technology
  • Concerns about deceptive trading
  • Lack of standard best practices
  • The fickle nature of banking relationships
  • Capital inefficiency
  • Security and transparency
  • The slow speed at which money and assets can move in and out

In the face of these issues found on cryptoasset exchanges, Gorelick hit on the large scale of the over-the-counter (OTC) markets.

Representatives from LedgerX and CME also provided updates on the state of the Bitcoin futures market later in the public hearing.

After gathering information from representatives of the cryptoasset industry and asking questions, the TAC voted unanimously to recommend that the CFTC create a new subcommittee focused on virtual currencies.

Blockchain Startup Po.et Nabs Former Washington Post VP as Its New CEO

Blockchain Startup Po.et Nabs Former Washington Post VP as Its New CEO

Po.et, a blockchain startup that allows content creators to create time-stamped titles for their written, visual and audio work, has announced Jarrod Dicker, who has held positions at the Washington Post, Time Inc. and Huffington Post, as its new CEO.

It may be the perfect match. Po.et wants to change the way content creators manage their work and Dicker has a history of ushering traditional news outlets into the digital age, so they are not solely reliant on advertising and subscriptions.

Dicker left his position as VP of innovation and commercial strategy at the Washington Post to join Po.et.  

“At Po.et, we are constructing what this industry needs  —  a new environment where creators are paid for what they can do instead of what is required of them by an old and broken paradigm,” he wrote in a blog post announcing the move. He explained that he left his former position at the Post because “I believe in that future.”

Dicker’s role at Po.et will be to oversee strategy and engineering and product development on the Po.et platform. He will also oversee Frost, an API and set of development tools that Po.et launched last week for content creators and bloggers.

In a statement, Dicker said he plans to leverage his experience “across media, education and corporate America to elevate this platform as the standard for digital content ownership rights.”

After joining the Washington Post, Dicker helped form the RED team, which stands for research, experimentation and development. Prior to that he worked at RebelMouse, a company founded by the core Huffington Post technology team, where he helped build the company’s future content management system. He also worked at Time Inc., taking the lead on emerging products, and at Huffington Post, originating native advertising.  

“Jarrod’s unique vision enables him to drive creative, scalable products and evangelize innovation,” said Tyler Evans, board member of the Po.et Foundation in a statement. “We look forward to his enthusiasm for media and track record of building cutting-edge technology for publishers to Po.et.”

Po.et. provides tools to publishers and content creators who want to automate the licensing process without involving third parties. All content licensing terms are enforced by smart contracts. Contract details, as well as ownership rights and other descriptions are then hashed and cryptographically registered on the Bitcoin blockchain.

Po.et, which held a token sale on August 8, 2017, now boasts an online community of more than 40,000 developers and creators on social media platforms, such as Telegram, Reddit and Twitter.

In addition to his role as CEO at Po.et, Dicker sits on the board of advisors for Rutgers University Center for Innovation Education and MOGUL Inc., a technology platform that enables women to share ideas and access content based on their personal interests. Dicker also supports a Carnegie Mellon University program on the value of social advertising in publishing.
