Canadian Authorities Seize Alleged Drug Dealer’s Bitcoin Holdings

Canadian Authorities Seize Alleged Drug Dealer’s Bitcoin Holdings

Canadian authorities have reportedly seized 288 BTC from a suspected drug dealer. Matthew Phan, a university dropout, is lobbying for access to at least half of his bitcoin holdings, claiming that not all of the seized bitcoin was used in illegal activities. This is the first instance where authorities have taken over a suspect’s cryptocurrency holdings in Canada.

A Long Time Coming

According to a report by The Star, Canadian police began their investigation into Matthew Phan and his activities in 2015. The law enforcement officers were acting on information provided by the American security agency Homeland Security.

Using the tips from Homeland Security, Canadian authorities concocted a plan where they posed as participators in an illegal trade on the dark web. Through their pseudonymous personas, Canadian authorities garnered evidence of Phan transacting on a handful of dark web marketplaces. Additionally, the officers found evidence that Phan was using bitcoin to facilitate his activities.

The Phan case represents the first instance in which Canadian authorities have planned a trap for a suspect who was believed to be participating in illegal activities on the dark web. Through the undercover agents, Canadian authorities targeted Phan and acquired evidence of his dealings on the dark web. Additionally, they were also able to seize the BTC Phan held in the addresses he utilized during his dark web activities.

Caught in the Act

Following their extended surveillance campaign, authorities acquired evidence showing Phan collecting a firearm he had purchased through the dark web using his bitcoin holdings. Canadian officers witnessed Phan go to a local post office where he fetched what he thought would be a Glock pistol. However, the firearm ultimately turned out to be a flare gun.

Despite the fact that Phan did not get the Glock, authorities believed they had enough evidence of his illegal activities on the dark web to request a search warrant from the relevant authorities. Their request was successful and shortly after the post office sting, Canadian officers raided Phan’s residence as well as his storage locker.

The court sanctioned search unearthed a number of restricted materials at Phan’s residence and locker. The lead prosecutor in the case, Erin Pancer, disclosed that marijuana, cocaine, ketamine, and MDMA were found in Phan’s belongings. Pancer further added that the amount of the restricted items came to thousands of grams each.

Moreover, the search team found a number of items, such as addressed envelopes,  which the prosecution used as evidence for drug trafficking. Also, authorities retrieved the physical devices Phan used to log in to the dark web sites. It is through the seized computers that a police officer named Dwayne King gained access to Phan’s bitcoin wallet.

King set up an entirely new wallet and then transferred Phan’s 288 BTC . Canadian authorities believe this heralds a new age in which criminals are able to store their illegal gains in a more sophisticated manner. King stated: 

“Not many years ago criminals kept their ill-gotten gains in shoeboxes hidden in their closets or under their mattresses. Cryptocurrencies have changed what that shoebox looks like and where it is hidden.”

Defending his position, Phan explained that he used his BTC holdings to participate in gold-trading facilitated by cryptocurrencies. However, the presiding judge ruled that while Phan may have used his BTC for legitimate reasons at some point, the evidence pointed to a significant amount of illegal activity facilitated by the BTC holdings.

The Phan case has brought cryptocurrency related crime to the forefront in Canada. King, who no longer works for the  Canadian authorities, explained:

“It forced agencies to start thinking about cryptocurrency investigations as a reality more than a possibility. A lot of agencies across the country were not ready to properly investigate cryptocurrency-related cases.”

In the Phan case, the presiding judge will decide on the fate of the suspect’s bitcoin holdings on April 4, 2019.

The Moonbeam Scaling Network: A “Semi-Decentralized” Scaling Solution

Moonbeam scaling solution

bitcoin exchange and hosted wallet provider Luno (formerly BitX) is developing a bitcoin scaling solution called Moonbeam. Unlike the lightning network, Moonbeam does not require SegWit’s transaction malleability fix and would be able to operate on the bitcoin network as it is today.

Moonbeam  aims to provide a way for multi-user bitcoin platforms — such as exchanges, hosted wallets, and payment processors — to easily open standardized one-way payment channels with each other, and thereby offload the bitcoin network from a growing number of transactions.

How Does it Work?

Moonbeam aims to take advantage of the fact that many bitcoin transactions occur among multi-user platforms. Using Moonbeam, these platforms can open standardized one-way payment channel contracts with one another to facilitate payments. By taking these transactions off-chain, Moonbeam can reduce transaction fees for those who use it and benefit bitcoin users generally by reducing congestion in the mempool.

These channels are simple smart contracts in which one party locks up a certain amount of bitcoins for a specified period of time (with the end point referred to as the “timeout”) for the purpose of sending payments to the other party. Before the timeout, the party that has locked up funds can send an unlimited number of off-chain transactions using those locked up bitcoins (until the channel runs out of bitcoins). Each channel involves only two on-chain transactions: one to open the channel and one to close it.

Because these intermediate transactions are off-chain, they are nearly instant. Without the need for a blockchain confirmation, the transactions only take as long as it takes to route an http request (think: loading a simple web page). These transactions would also be cheap. Only two transactions per channel require miner fees, and the rest are essentially free to the platform, though the platform could charge fees to its users.

The one-way payment channels used by Moonbeam are not a new invention. bitcoin inventor Satoshi Nakamoto embedded preliminary code for payment channels in the very first release of bitcoin, and more recent protocol upgrades like CheckLockTimeVerify have further enabled this usecase. bitcoin platforms could negotiate and implement these smart contracts on the blockchain today.

What Moonbeam aims to do is facilitate the creation of these channels between major payment platforms by using the Domain Name System (DNS) to route communications related to creating and using these channels. This way, high volume platforms can easily discover one another and enter into a payment channel smart contact using the standardized Moonbeam terms. Using the Moonbeam protocol, this process can happen automatically when it is more efficient to open a channel than sending payments on-chain.

Trust

The Moonbeam project overview indicates that it is “semi-decentralized.” It is labeled as such because while the Moonbeam network does not require platforms to trust one another, it does require users to trust their platforms. A hosted wallet with a Moonbeam address is a custodial account, where the platform is managing the funds, and credits and debits user accounts accordingly as users send and receive transactions. Exchanges such as Coinbase operate in this manner; users do not directly control their private keys. Moonbeam can be a useful tool for these services, but it will likely not be a suitable scaling solution for users who prefer to manage their own private keys.

Other Downsides

The Moonbeam specification document also mentions several other potential downsides. Among them is the cost of capital. In order to open these channels, sending platforms must commit capital in the form of bitcoin for a period of time. If the receiver does not use the channel, the sending platform must wait until timeout to regain control of the funds, entailing potentially large financing costs.

Another risk involves the use of DNS. DNS hijacking is an attack that involves rerouting domain name requests to an attacker’s server. These attacks could be used to receive payments over new channels that were meant for the authentic server.

While Moonbeam does not offer the level of decentralization of the lightning network, the fact that it does not require any fork to the network may may make it an attractive solution to bitcoin’s scaling troubles in the short term. It could be implemented by hosted wallet providers as soon as the project is production ready.

The current state of Moonbeam can be found on the project’s Github.
