US Patent 11995644 System and method for managing transactional interoperability amongst blockchains

Disclosed is system and method for managing transactional interoperability amongst plurality of blockchains, the plurality of blockchains comprising a non-host blockchain and a host blockchain. The server arrangement is configured to append a first transaction to the non-host blockchain, first transaction comprising metadata pertaining to the user transaction, append a second transaction to the host blockchain, the second transaction comprising the first hash address, wherein second transaction triggers an initial smart contract of the host blockchain to store an operational information response at a second hash address in the distributed file storage system; append a third transaction to non-host blockchain, the third transaction comprising the second hash address, append a fourth transaction in the host blockchain, fourth transaction comprising third hash address, wherein the fourth transaction triggers initial smart contract of the host blockchain to update user wallet account based on output generated from the execution of user transaction.
