Bitcoin Startup Blockstream Raises $55 Million in Funding Round

By Paul Vigna 

Blockstream, a bitcoin-focused startup founded by some of the industry's most high-profile developers, raised $55 million in one of the largest funding rounds in the history of the virtual currency.

Investors including Horizon Ventures, Hong Kong magnate Li Ka-shing's venture-capital firm, Tokyo-based Digital Garage and the investment arm of insurance giant AXA Group contributed to the funding. Horizon Ventures also took a seat on Blockstream's board.

This is the latest in a string of deals that underscore the resilient appetite for bitcoin investments amid the anxiety in capital markets world-wide.

Last month, Digital Asset Holdings, a startup led by former J.P. Morgan Chase & Co. executive Blythe Masters, raised $52 million. On Tuesday, the firm said it had added Goldman Sachs Group Inc. and International Business Machines Inc. as investors, bringing that funding round's total to $60 million.

Launched in 2009, bitcoin is a digital currency that operates on a decentralized computer network without a monetary authority. In the last year, the technology underlying the currency, called blockchain, has garnered increasing attention from Wall Street firms. Banks are tinkering with the technology, joining development consortia and taking stakes in companies.

Blockstream's business is focused around an idea called " sidechains." These are bitcoin-like ledgers that operate independently of, but are pegged to, bitcoin. This allows users to build a separate platform for a specific use but still have access to the bitcoin blockchain.

Blockstream, which didn't disclose its valuation, plans to use the money to help expand its business. "Throughout our business and the world there is a huge opportunity right now to start changing some of the basic plumbing of traditional finance," said Chief Executive Austin Hill.

Blockstream raised $21 million in seed funding in 2014.

The company, based in Montreal, has released two products so far. Elements, is an open-source platform for building and testing applications that Mr. Hill likens to as a "Lego-constructor kit."

Liquid, designed for bitcoin exchanges, allows for high-speed transactions. Several exchanges, such as Kraken, BTCC, and Bitfinex, have already signed up for Liquid, which is expected to go live by the end of March. Exchanges under contract will pay a monthly subscription fee for use.

Blockstream last week said it would partner up with global accounting and consulting firm PricewaterhouseCoopers to build, deploy and maintain blockchain-based products for PwC clients. Another blockchain-focused startup, Eris Industries, is also member to that partnership.

Companies focused on virtual currencies raised $490 million in 2015, according to data from CoinDesk, an industry news service. Funding rounds so far in 2016 suggest the pace is picking up. In addition to the fundings by Blockstream and Digital Asset, a startup called Gem raised $7.1 million in early January, and investment firm Blockchain Capital raised $13 million for its second venture fund.

The $116 million raised by bitcoin startup 21 Inc. last year is the largest bitcoin-related fundraising round to date. The second largest is the $75 million raised by Coinbase in 2015.

Bitcoin companies have raised more than $1 billion during the currency's seven-year history.
