Ownership is as strong as holding bitcoin. No sidechains. No extra tokens. No trusted intermediaries. Computation cost is independent of the number of steps. Write normal JavaScript/TypeScript classes. Calling a method that changes state automatically builds, funds, signs and broadcasts a real transaction on a UTXO chain. Supported chains: Bitcoin · Litecoin · Dogecoin · Pepecoin Why Bitcoin Computer? - Native UTXO ownership — Smart objects are stored in outputs. Only the owner can update them. - Cost independent of computational complexity — All logic runs on the client. You pay for the size of the metadata, not for the number of computational steps. - Real JavaScript — No new language or virtual machine. Use the tools and libraries you already know. - Multichain by design — The same contract code runs on Bitcoin, Litecoin, Dogecoin and Pepecoin. - Perfectly sharded — Users only compute the objects they care about. There is no global state execution. - Composable — Objects can freely reference each other (with explicit ownership consent). - Compatible — Works alongside Ordinals, Runes, BitVM and other Bitcoin protocols. Quick Example You need to have node.js installed. First download and install the Bitcoin Computer library from npm: Then create a file index.mjs . Execute the smart contract.
