METHOD AND SYSTEM FOR VERIFYING POLICY COMPLIANCE OF TRANSACTIONS IN A BLOCKCHAIN EXECUTING SMART CONTRACTS

摘要

A method for enforcing policy compliance of a smart contract in a blockchain network includes a blockchain node receiving a transaction and a transaction policy associated with the transaction, where the transaction includes the smart contract and a first state. The blockchain also determines a second state of the transaction based upon executing the transaction according to the smart contract and the first state, and determines whether the transaction complies with the transaction policy. If the transaction complies with the transaction policy, the second state is incorporated by the blockchain node into a new block of blockchain of the blockchain network. If the transaction does not comply with the transaction policy, the first state is incorporated by the blockchain node into the new block.
