* Ethereum: an alternative protocol for building decentralized applications, providing a different set of tradeoffs for a large class of decentralized applications, that focuses on situations involving rapid development time, requiring security for small and rarely used applications, and offering wide-ranging, agile interaction. It has an abstract foundational layer: a blockchain with a built-in Turing-complete programming language so that anyone can write smart contracts and decentralized applications with their own arbitrary rules for ownership, transaction formats, and state transition functions.<ref>[https://ethereum.org/en/whitepaper/#alternative-blockchain-applications Alternative Blockchain Applications, Ethereum.org]</ref> | * Ethereum: an alternative protocol for building decentralized applications, providing a different set of tradeoffs for a large class of decentralized applications, that focuses on situations involving rapid development time, requiring security for small and rarely used applications, and offering wide-ranging, agile interaction.
