Trading information verification method and trading information verification system

Abstract

The invention discloses a trading information verification method and a trading information verification system. Whether each second node is used as a verification node verifying trading information is determined according to at least one hash value of trading information and the hash values of all the nodes in a block chain network. Thus, verification nodes corresponding to all the hash values of trading information are obtained. The second node determined as a verification node is selected randomly without rules. A second node determined as a mining node judges whether trading information passes verification according to the number of signatures of the verification node corresponding to the trading information. The possibility of malicious counterfeiting and cheating is prevented. There is no need for every node to verify the trading information. The workload of trading information verification is reduced.

Description

technical field

[0001] The invention relates to the technical field of the Internet, in particular to a transaction information verification method and system. Background technique

[0002] Blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data. Information cannot be forged and tampered with. Smart contracts can be automatically executed without any audit by a centralized organization.

[0003] On the blockchain network, in order to ensure the validity of all transaction information, each node must verify the transaction information after receiving the transaction information. Only the verified transaction will be propagated by the node to its connected node, otherwise the transaction information is discarded.

[0004] However, since each node has to verify the transaction information for each transaction information, when the number of nodes in the blockchain network is very large, this process will generate a c...
