Solidity

Solidity is a statically-typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine as well as on other private blockchains running on platforms that compete with Ethereum. With Solidity, developers are able to write applications that implement self-enforcing business logic embodied in smart contracts, leaving a non-repudiable and authoritative record of transactions.
