A block chain member management method and system based on an identification cryptographic algorithm

Abstract

The invention relates to a block chain member management method and system based on an identification cryptographic algorithm. The method of the invention comprises the following steps: (1) registering a user of a block chain network through a block chain client, and generating a signature private key according to the user identity information by using an identification cryptographic algorithm; (2) loging in the block chain network through the block chain client by a user; 3) initiating a block chain network transaction by the user, and using an identification cryptographic algorithm to sign adigital summary of the transaction calculated by the user's block chain client end to generate signature information; (4) verifying the block chain network transaction initiated by the user, and verifying the correctness of the signature of the block chain network transaction by using the identification cryptography algorithm. The method and the system of the invention can reduce the complexityof the management of the members in the block chain network and facilitate the audit of the transaction.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain member management method and system based on an identification cryptographic algorithm. Background technique [0002] The earliest blockchain technology appeared in the Bitcoin project. On October 31, 2008, a person with the pseudonym Satoshi Nakamoto (Nakamoto Satoshi) proposed the Bitcoin design white paper (first seen on the metzdowd mailing list), and released the initial implementation code in 2009. Since 2014, the Blockchain technology behind Bitcoin has attracted everyone's attention, and has officially triggered a wave of innovation in Distributed Ledger technology. [0003] From a technical point of view, Bitcoin is a remarkable innovation in the history of digital currency. The Bitcoin network is composed of thousands of core nodes without any central operation and maintenance participation, which supports a steadily increasing transacti...

Problems solved by technology

Bitcoin provides good anonymity, making it impossible to trace the identities of both parties

[0006] Disadvantage of existing technology 1: because there is no member management system in the Bitcoin network, the ID cards of both parties in the network cannot be traced back, so it is impossible to audit and supervise transactions and user identities

[0008] Disadvantages of existing technology 2: Fabric member management service uses the identity authentication mechanism of the PKI / CA certificate system, which involves the application, issuance and verification of certificates, which is complicated to use, difficult to develop and integrate, and difficult to deploy for application vendors
