![]() In Ethereum, smart contracts represent a piece of code written in a high-level language (Solidity, LLL, Viper) and stored as bytecode in the blockchain, in order to run reliably in a stack-based virtual machine (Ethereum Virtual Machine), in each node, once invoked. The Ethereum virtual machine and smart contracts are key elements of Ethereum, and constitute its main attraction. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. Solidity is statically typed, supports inheritance, libraries and complex user-defined types among other features. Solidity was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM). Smart contracts are programs which govern the behavior of accounts within the Ethereum state. Solidity is an object-oriented, high-level language for implementing smart contracts. Although Ethereum borrows many ideas that were initially introduced by bitcoin, there are many divergences between the two. Ethereum was designed with a broader vision, as a decentralized or world computer that attempts to marry the power of the blockchain, as a trust machine, with a Turing-complete contract engine. Ethereum is a general-purpose blockchain that is geared toward describing business logic, through advanced scripts, also known as smart contracts.
