Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, the systems on the market are basically centralized management of permissions, and super administrators have all permissions, which does not meet the original intention of the alliance chain design, and also has security issues, rather than centralized management of signatures The collection scheme (such as point-to-point sending signature) is not convenient and inefficient when multi-organization coordination is required. The multi-party signature collection scheme based on Hyperledger-fabric proposed by the present invention

Embodiment 1

[0040] Such as figure 1 As shown, the hyperledger-fabric-based multi-party signature collection scheme described in the present invention includes baas; the baas involves each organization deploying its own on-chain management platform, and the distributed deployment of the platform ensures their respective authority security. All collaborative operations ensure the security and traceability of operations through the interaction on the chain to meet the concept of distributed ledgers in the blockchain. The steps are as follows:

[0041] S1: The organization initiates a collaboration request;

[0042] S2: The chain organization Baas accepts requests through chain events and generates corresponding event feedback organizations;

[0043] S3: Each organization handles the event and decides whether to agree to sign the data;

[0044] S4: The organization baas on the chain collects the signatures and data of other organizations through events and feeds back to the organization;

...

Embodiment approach

[0047] As an embodiment of the present invention, the request for the organization to initiate collaboration in the S1 is to invite the organization / install the chain code; the S1 further includes the following steps:

[0048] a) the organization initiates a request for collaboration;

[0049] b) Baas initiates a transaction by calling the built-in collaboration contract to upload its own signature and request to the chain;

[0050] c) After the transaction is successful in the Fabric network, each node sends an event notification;

[0051] The data interaction through the contract in b mentioned above can ensure the reliability and traceability of the data; when working, the signature in this scheme does not verify the signature, and the submitted signature will be verified by the final submission of the fabric, which does not need to be on baas Perform signature verification.

[0052] As an embodiment of the present invention, said S2 further includes the following steps: ...

Abstract

The invention belongs to the technical field of regional chains, and particularly relates to a multi-party signature collection scheme based on Hyperledger-fabric. The baas deploys an on-chain management platform for each organization, the authority safety of the organization is ensured through distributed deployment of the platforms, and all cooperative operations are interacted through the on-chain to ensure the safety and traceability of the operations, so that the concept of a distributed account book of the block chain is met. The method comprises the steps that S1, organizations initiate a collaboration request; S2, an on-chain organization Baas accepts the request through an on-chain event, and generates a corresponding event to feed back to the organizations; S3, the organizations respective process events, and determine whether to agree to sign the data or not; S4, the on-chain organization baas respectively collects signatures and data of other organizations through events and feeds back the signatures and the data to the organizations; and S5, the event initiator confirms the result and submits the result. The invention provides a multi-party signature collection scheme based on Hyperledger-fabric so as to solve the problem that a Hyperledger-fabric alliance chain needs cooperation in which multiple organizations participate.

Description

technical field [0001] The invention belongs to the technical field of area chains, in particular to a multi-party signature collection scheme based on Hyperledger-fabric. Background technique [0002] The baas system developed based on Hyperledger-fabric must face the problems of configuration modification (organization joining, channel policy modification, etc.), installation of chain code (version 2.0 and above), etc., which require the cooperation of various organizations to operate. The baas system must be in the alliance chain Under the premise of a decentralized system, users can complete assistance more simply and conveniently. [0003] When the Hyperledger-fabric consortium chain needs to modify the channel configuration, it needs to collect the signatures of the organizations participating in the channel according to the policy configured on the channel configuration (the default is most organizations on the channel). The channel configuration is related to all par...
