Abstract

Embodiments of the invention provide a block chain-based transaction verification method and apparatus, and an electronic device. The method comprises the following steps: receiving a transaction sent by a client; wherein the transaction comprises a cryptographic proof which is acquired by the client from node equipment which does not participate in consensus in a block chain and is used for proving that a target account related to the transaction is included in a block chain account book of the block chain, and the state data of the target account is included in the cryptographic proof; carrying out legality verification on the transaction; wherein the legality verification comprises the step of verifying the cryptographic proof based on a cryptographic algorithm; and if the legality verification is passed, executing the transaction, and after the execution result of the transaction reaches a consensus with the execution result of the transaction by other nodes participating in the consensus in the block chain, sending the transaction and the execution result of the transaction to node equipment not participating in the consensus in the block chain, and sending the transaction and the execution result of the transaction to the node equipment which does not participate in the consensus in the block chain. And storing in the block chain account book.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular, to a blockchain-based transaction verification method and device, and electronic equipment. Background technique [0002] In the existing blockchain, the accounting node needs to verify the legality of the transaction before packaging the transaction into the block, and only when the transaction is legal can it be packaged into the block. [0003] The verification of legitimacy is mainly based on the state data in the blockchain ledger. Therefore, each node device participating in the transaction consensus needs to maintain the full amount of state data in the blockchain ledger locally. [0004] However, with the increase of business, state data will continue to increase in the blockchain ledger, and the increase of state data will not only continue to occupy storage space, but also reduce the verification efficiency of node devices participa...
