L2O-A

A set of standards for building arbitrary stateful computation on bitcoin.​

Benefits​

  • Allows for zkRollups, zkVMs, zkEVMs, etc. to be trustlessly deployed on bitcoin
  • Can be used for general computation/all use cases (one indexer/OrdHook for all the features we want on BTC)
  • Backwards compatible with BRC-20, can easily build secure, trustless DEXs/DeFi on Bitcoin
  • Only requires nodes to index an extra few kilobytes of data per L2 + a used withdrawal id map (storage = total number of withdrawals * 8 bytes)
  • Can be used to build trustless bridges with Ethereum and other L1
