Moon Rabbit is a Substrate-based distributed infrastructure that enables any type of data or digital asset transfer between any blockchains, offering full interoperability and scalability. It permits anyone to launch their own Jurisdictions with unique capabilities (blockchains, DeFi protocols, NFTs, eSports, Web3 dApps, cryptocurrencies, etc.). Jurisdictions are able to communicate with each other and to develop their own specialisations and business models, permitting cross-chain communications and process distribution. Jurisdictions may either be transparent and permissionless, or private and permissioned, making Moon Rabbit suitable both for community and enterprise applications. Thus, Moon Rabbit is a System of Systems, uniting all distributed ledgers and becoming the ultimate protocol to unite various chains at an abstract level — a Metachain.
