Blockchain.info is a bitcoin wallet and block explorer service. Launched in August 2011, the service provides data on recent transactions, mined blocks in the bitcoin block chain, charts on the bitcoin economy, and statistics and resources for developers. Information from and links to the website are common in media coverage and in bitcoin forums. The Blockchain.info mobile app for Android allows users to securely send and receive bitcoins and browse block chain information. In December 2013, the company acquired ZeroBlock LLC, makers of the leading mobile bitcoin app.
Blockchain.info was the world's most visited bitcoin website in 2013, with over 118 million page views and over 3 million unique visitors in November 2013, and in January 2014 Blockchain.info reached one million user wallets.
In February 2014, Apple Inc. removed the Blockchain app from the iOS App Store, prompting a harsh response from Blockchain and public outcry in the bitcoin community, most notably within the Reddit community. In July 2014, Apple reinstated the Blockchain app back into the iOS App Store.
In October 2014, Blockchain.info closed a $30.5m fundraising round from Lightspeed Venture Partners and Mosaic Ventures, which was the biggest round of financing in the digital currency sector at that time. 
In December 2014, Blockchain.info became one of the first prominent Bitcoin wallets to offer a dedicated hidden service on the Tor network, for users who desire to conduct Bitcoin transactions with greater privacy and lesser third party surveillance, as well as to provide end-to-end encryption for Tor users who were previously vulnerable to malicious exit nodes sniffing their keys and stealing their Bitcoins.
In early 2015, the company passed 3 million wallets created using their services.
In August 2015, Blockchain.info's CEO Peter Smith was invited to accompany UK Prime Minister David Cameron on a tour throughout southeast Asia to engage with local representatives about the UK's leading role as a global fintech hub.
Also in August 2015, Blockchain.info passed 4 million wallets created using their services.
