🔨 Built on Ethereum

There is an explosion of innovation happening on Ethereum and we as a community should be highlighting this for the world to see. That’s why we’ve created a branding kit that dApp developers can use to show off that their products and services are built on the most powerful, secure and used smart contract platform on the planet. The branding kit is completely free to use so we encourage all developers to place it somewhere appropriate on their product or service.

Also, don’t forget to tune into our weekly recap podcast to hear all about Erics adventures at blockchain week - it’s due to go out in around 36 hours from now.

Have a great week everyone!


News of the Week

💸 Coinbase May Acquire Xapo

Coinbase is in advanced talks to buy custody provider Xapo for ~$50 million plus an earn-out in order to boost its custody business.

Coinbase and Fidelity Digital Assets have been locked in a neck-and-neck race for the prized asset for the past few weeks, with Coinbase ultimately prevailing. If the tentative terms being discussed hold, Coinbase will pay ~$50 million in cash for Xapo, plus a contingent earn-out for remaining with the company. Xapo raised $40 million since its founding in 2012.

Xapo’s core product is cold storage vault custody of bitcoin, with rumors that the company holds as much as $5.5 billion of assets under custody (AUC) at the current $BTC price near $8,000, reflecting ~700K bitcoin under custody. Xapo custodies 226,000 BTC that are part of Grayscale Bitcoin Trust.

🤔 Facebook Registers Secretive ‘Libra’ Cryptocurrency Firm in Switzerland

According to a Reuters report, Facebook registered a new company, Libra Networks, in Geneva on May 2. This coincides with the slow roll-out of their internal cryptocurrency that will define the company’s first foray into blockchain technology.

Facebook Global Holdings is a stockholder in the new company and it will, according to Reuters, “provide financial and technology services and develop related hardware and software, plans submitted on the Swiss register reveal.”

Facebook’s march towards crypto has been slow and steady. The company’s latest move, the hiring of two Coinbase compliance managers, happened on May 14.

😕 Amazon Wins Patent for Proof-of-Work Cryptographic System

Tech giant Amazon has been granted a patent for various techniques to build a proof-of-work (PoW) cryptographic system similar to those used by blockchains such as bitcoin.

First filed in December 2016 and awarded Tuesday by the U.S. Patent and Trademark Office (USPTO), the patent outlines how Merkle trees can be generated as a solution to a proof-of-work challenge, among other benefits.

News of the Week

🤣 U.S. Congressman Wants to Ban Crypto

In a Financial Services Committee hearing on Thursday, U.S. Congressman Bradley Sherman (D-CA) called on Congress to propose a bill outlawing cryptocurrencies.

"I look for colleagues to join with me in introducing a bill to outlaw cryptocurrency purchases by part because an awful lot of our international power comes from the fact the dollar is the standard unit of international finance and transactions," Sherman said.

"Whether it is to disempower our foreign policy, our tax collection enforcement, or our traditional law enforcement, the purpose of cryptocurrency, the advantage it has over sovereign currency is solely to aid in the disempowerment of the United States and the rule of law," he added.

Ed note: I can’t think of a better advertisement for cryptocurrencies!

😲 Hackers Steal $40.7 Million in Bitcoin from Binance

Hackers stole more than 7,000 bitcoin from crypto exchange Binance, the world’s largest by volume, the startup reported Tuesday.

Binance announced that a “large scale security breach” was discovered earlier on May 7, finding that malicious actors were able to access user API keys, two-factor authentication codes and “potentially other info,” the exchange’s CEO, Changpeng Zhao, said in a letter. As a result, they were able to withdraw roughly $41 million in bitcoin from the exchange, according to a transaction published in the security notice.

After the hack, CZ publicly discussed whether the company might seek to encourage bitcoin miners and node operators to “rollback” the bitcoin blockchain, reversing transactions confirmed by the network to return the funds.

Shortly after discussing this option, CZ said in a follow-up tweet that after speaking with various parties, the exchange decided not to pursue the rollback approach.

👍 FinCEN Offers Some Clarity for Crypto

The Financial Crimes Enforcement Network (FinCEN) published a new guidance sheet Thursday, outlining when and how different companies, individuals and platforms in the crypto space may be money transmitters under the Bank Secrecy Act (BSA) and other relevant laws. The document highlighted dapps among other models.

Being designated a money transmitter under FinCEN rules means a firm or person must follow federal AML and know-your-customer (KYC) regulations.

In Thursday’s notice, the U.S. Treasury Department’s AML bureau said that while it “does not establish any new regulatory expectations or requirements,” it does combine several previous documents issued over the past eight years, and details in greater specificity how participants in the space might violate AML regulations.

Dapps, the document noted, are “designed such that they are not controlled by a single person or group of persons,” meaning there is no single entity operating as the dapp’s administrator.

However, if a dapp “accept[s] and transmit[s] value,” it qualifies as a money transmitter under the same regulatory interpretation applied to crypto-dispensing vending machines, FinCEN said.
