Launched in 2013 by Dan Held and Kevin Johnson, ZeroBlock was a website and mobile app that provided bitcoin exchange data and aggregated news. The company later acquired bitcoin trading platform RTBTC and created a trading platform of its own that integrated its news feature.
ZeroBlock was acquired by crypto wallet company Blockchain in December 2013 for an undisclosed amount. At that time, Held joined the Blockchain team as a product manager.
The ZeroBlock platform displayed bitcoin’s prices in relation to the three most traded currencies at the time, Chinese yuan, U.S. dollars and euros, while gathering data from BTC China, Mt. Gox, BitStamp, BTC-e and Coinbase, the world’s leading exchanges in 2013. In 2014, ZeroBlock acquired RTBTC, a real-time bitcoin trading platform, with the idea that users would pay $20 per month for unlimited trading through a pro-version of their mobile app.
ZeroBlock closed down in 2016 for undisclosed reasons. At the time, Blockchain CEO Nic Carey said that Blockchain would continue maintaining the iOS and Android ZeroBlock apps, but not the trading platform.
