Bitcoin is an open source peer to peer electronic cash system. Because the code is open source, the idea is public domain and the name, symbol and concept is all considered a public good, it has functioned fully for 14+ years without a centralized entity baby sitting its existence. Bitcoin is not only an open source software project, a new digital asset within its own class, a peer to peer computational system, the largest computer network on earth, but it is also the bedrock of a new government, a new form of society & the foundation for a modern civilization. Our company was formed to further that mission, that goal and that purpose of Bitcoin, without anyone permission or approval, to use the Bitcoin brand, name and technology, to fulfil the potentiality of Bitcoin. By creating the tools, products & services in the original vision of the Satoshi Client, we provide the essential parts of Bitcoin to the public, to institutions and the world at large.

Ethereum is a platform and a programming language that makes it possible for any developer to build and publish next-generation decentralized applications. Ethereum can be used to codify, decentralize, secure and trade just about anything: voting, domain names, financial exchanges, crowdfunding, company governance, contracts and agreements of most kind, intellectual property, and even smart property thanks to hardware integration. Ethereum borrows the concept of decentralized consensus that makes bitcoin so resilient, yet makes it trivial to build on its foundation. To find out more about how Ethereum works, consult the whitepaper. This page is managed and operated by members of the Ethereum Foundation.
