Abstract
A method for sharing data between blockchains in a multi-chain network comprising accessing a first block on a first blockchain of a multi-chain network, generating a cryptographic hash from the first block, defining a first anchor hash, recording the first anchor hash to a second block on a second blockchain of a multi-chain network, receiving a plurality of account addresses associated with the first and second blockchains and an account state for each account associated with the plurality of account addresses, a plurality of transactions, and a plurality of transaction receipts, generating a world state trie comprising a mapping between the first plurality of account addresses and the account states, a transactions trie comprising the plurality of transactions, and a transaction receipts trie comprising the plurality of transactions receipts, and root hashes thereof, and recording the root hashes to each block of the first and second blockchains.
