"Ever since Loot Project exploded, and I heard a poker player bought a bag of randomly generated words for a million dollars, I’ve been thinking about composability: the major innovation of Ethereum over its predecessors. Smart contracts (programs stored on the blockchain that run when predetermined conditions are met) are the code that power NFTs, DeFi, and DAOs. They’re composable, which means they’re like legos — the contracts are building blocks that can be programmed to interact with each other."
