Abstract

The invention discloses a signing system based on multi-party consensus of alliance chains, aiming at providing infrastructure of private fund industry, providing a private fund online signing management system based on alliance chain system, supporting multi-party participation and consensus, encrypting and verifying data for private fund entrusting party, management party and custodian party. The technical scheme is as follows: the contract signing scheme realized by the contract signing system of the invention, in which encryption sharing and multiple independent signatures are carried outsimultaneously, cannot only ensure that the electronic contract is not leaked on the block chain, but also can effectively verify whether the contract is tampered with or not. Moreover, the block chain multi-party consensus algorithm in the system of the invention can efficiently complete the minimum consensus of four nodes and prevent malicious nodes from modifying data. In addition, the heterogeneous contract storage design in the system of the invention can combine the traditional database system and the block chain system to realize the classified storage of the data on the chain and underthe chain, which is convenient for the local search and inquiry and ensures that the commercial secrets are not disclosed.

Description

technical field [0001] The present invention relates to a contract signing technology based on blockchain, in particular to a contract signing system based on alliance chain multi-party consensus, which is applied to the field of private equity fund contract signing. Background technique [0002] Blockchain is a brand-new distributed database technology. Multiple stakeholders jointly maintain a growing directed data record. These data maintain data security and timing relationships through cryptography and privacy protection technology, making it difficult for participants to tamper and deny and counterfeiting. The alliance chain is a blockchain system with a permission access mechanism. The alliance chain has created a new type of multi-party consensus algorithm economic model, which is difficult to tamper with, free and open, highly trustworthy data, and strong fault tolerance. Equal and voluntary market transactions between subjects. [0003] my country's private equity...
