About the Ethereum Foundation

The Ethereum Foundation (EF) is a global non-profit organization dedicated to supporting Ethereum and related technologies. Our mission is to do what is best for Ethereum’s long-term success. Our role is to allocate resources to critical projects, to be a valued voice within the Ethereum ecosystem, and to advocate for Ethereum to the outside world.

About Solidity

Solidity is a statically-typed curly-braced programming language designed for developing smart contracts that run on Ethereum. In the coming years, we intend to build a new foundation for the language with a small, logically-grounded and verifiable language core on top of which higher-level functionality can be constructed definitionally. For this task, we are seeking both theoretical and practical contributions.
