Web-based bitcoin wallet Blockchain seems to have benefitted from all of the bitcoin buzz in the past month. The Luxembourg-based company pulled in a Series B round of $40 million today, bringing its total raised to $70 million.

The funding, which the company describes as “rocket fuel” in its blog, comes from new investors Lakestar, GV (formerly Google Ventures), Nokota Management, and Digital Currency Group. Existing investors Lightspeed Venture Partners, Mosaic Ventures, Prudence Holdings, Virgin, and Sir Richard Branson (Virgin Group) also participated.

Since it was founded in 2011, Blockchain has amassed millions of active users from across the globe, formed partnerships in 34 countries, and has built an API platform used by large fintech companies. The company anticipates the new funds will help it deliver its mission to “create an open, accessible, and fair financial future for billions across the globe, one piece of software at a time”

Blockchain presented at FinDEVr 2014, when the company was hosting 2 million wallets on its platform. Today, the company boasts 14 million wallets. Blockchain differentiates itself from competitor wallet Coinbase because, unlike Coinbase, it does not host cryptocurrency exchanges on its site. Instead, Blockchain has set up partnerships with exchanges so that it cannot see users’ transactions or balance amount.

Earlier this year, Blockchain partnered with Imperial College London to launch the Digital Asset Research Lab, an environment that supports research and activities related to cryptocurrencies and blockchain technologies. Late last year, the company announced plans to add a buying option to its wallet.
