Abstract

The present invention discloses a blockchain transaction method based on multi-user CA digital certificates, which includes the following steps: Step 1: Members of the user group participating in the transaction apply for CA digital certificates from the CA server with their respective public keys and signatures, and after passing the review , the CA server generates a multi-user CA digital certificate; Step 2: User group members initiate a transaction request; Step 3: Verify whether the issuer of the multi-user CA digital certificate is qualified; Step 4: Confirm the transaction. A block chain transaction method based on a multi-user CA digital certificate of the present invention can effectively reduce the complexity in the multi-user transaction process and improve transmission efficiency and processing speed.

Description

technical field

[0001] The invention relates to the technical field of block chain transactions, in particular to a block chain transaction method based on multi-user CA digital certificates. Background technique

[0002] Blockchain is a distributed consensus network, which broadcasts transactions in network nodes through P2P, and makes transactions reach consensus in the blockchain network to maintain node ledger consistency, reliability and non-tamperable modification.

[0003] For transactions in the blockchain, the authenticity verification of the source is a crucial link. In this process, the traditional method is to use an asymmetric key to create a signature for the transaction information using the private key of the transaction user node, and then send its own public key and signature information to the consensus node, and the consensus node verifies the information through the public key. integrity. This method can effectively guarantee the security and integrity...
