| description | 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 de |
