Andresen graduated from Princeton University in 1988. He began his career working on 3D graphics software at Silicon Graphics Computer Systems. In 1996, he co-authored the VRML 2.0 specification, and later published a reference manual for VRML 2.0. Since leaving Silicon Valley in 1996, Andresen has tackled a wide variety of software-related ventures, including CTO of an early voice-over-the-Internet startup and co-founder of a company that made multiplayer online games for blind people and their sighted friends.
Bitcoin
Andresen was the lead developer for a part of the bitcoin digital currency project, working to create a secure, stable "cash for the Internet." Andresen discovered bitcoin in 2010, considering its design to be brilliant. Soon after he created a website named The Bitcoin Faucet which gave away bitcoin. In April 2011, Forbes quoted Andresen as saying, "Bitcoin is designed to bring us back to a decentralized currency of the people," and "this is like better gold than gold." After joining the developers contributing to Bitcoin along with Satoshi Nakamoto, he went on to become lead developer of the client software for the bitcoin network which is now known as Bitcoin Core. He stepped back as lead maintainer in 2014. Andresen also created ClearCoin, an escrow-type of service, which was closed on about June 23, 2011. After several years working on the software, Andresen left the role of lead developer of bitcoin to work on the strategic development of its technology. He conceived of the Bitcoin Foundation which became reality in 2012. In May 2016 Andresen stated that the Australian programmer and entrepreneur Craig Wright was Satoshi Nakamoto, but later expressed regret getting involved in the “'who was Satoshi' game." Andresen has not contributed to Bitcoin Core since February 2016. He had become critical of the failure of bitcoin developers to increase network capacity, and helped put together Bitcoin XT as alternative software. His commit access to Bitcoin Core on GitHub was revoked in May 2016 after stating Wright is Satoshi Nakamoto. In November 2017, Andresen expressed support for rival currency Bitcoin Cash, stating "Bitcoin Cash is what I started working on in 2010".
