Problems solved by technology

Due to the lack of interoperability between different blockchain applications, credible data circulation and value exchange cannot be carried out effectively. Each blockchain has become an isolated island of trust, which has largely hindered the integration and development of blockchain application ecology.

Embodiment 1

[0029] This embodiment proposes a task process traceability system based on blockchain cross-chain collaboration, such as figure 1 As shown, it includes link data routing module, blockchain A, blockchain B, blockchain C, blockchain A adapter, blockchain B adapter, and blockchain C adapter. Blockchain A, blockchain B, and blockchain C are respectively connected to the link data routing module through their respective blockchain adapters.

[0030] In this embodiment, since the internal data protocols of different blockchains are different, it is necessary to transfer the business data of different blockchains to the common business data protocol through the blockchain adapter. The data entities of different blockchains realize the unique ID mapping in the cross-chain data routing. The unique ID can be located in the specific business blockchain in the cross-chain data routing, and the data entity can be identified through the business ID in the specific business blockchain. ope...

Embodiment 2

[0032] This embodiment provides an exemplary workflow based on the system described in Embodiment 1, specifically as figure 2 shown, including the following steps:

[0033] (1) A user of blockchain A initiates a transaction;

[0034] (2) The blockchain adapter of blockchain A converts the transaction content into a data format supported by the link data routing module and sends it to the link data routing module;

[0035] (3) The link data routing module addresses according to the ID of blockchain B carried in the transaction content, and sends the transaction content to the blockchain adapter of blockchain B;

[0036] (4) The blockchain adapter of blockchain B converts the transaction content into the data format supported by blockchain B and then uploads it to blockchain B, and receives the transaction receipt returned by blockchain B and confirms that the transaction has been completed. On-chain Merkle proof;

[0037] (5) The blockchain adapter of blockchain B forwards ...

Embodiment 3

[0041] At present, in some job types with clear task objectives, quantifiable results, or strong independence in the execution of job tasks, and low requirements for cooperation and cooperation, companies often adopt flexible employment models to reduce labor costs. However, there are the following problems in the specific operation of flexible employment: (1) There is a risk of false invoicing; (2) There is a lack of effective collection methods, and the task process data is missing; (3) The task process data has a single dimension and insufficient credibility.

[0042] Because there is a cooperative relationship between the enterprise and the individual who undertakes the task, the individual can pay according to the operating income, so to ensure that this model is recognized, it is necessary to ensure the authenticity of flexible employment. For HRO organizations that carry out flexible employment business, the C-end is the customer, so as to form an operation logic that ta...

Abstract

The invention provides a task process tracing system and method based on block chain cross-chain cooperation. The system comprises a link data routing module, block chain adapters and at least two different block chains, and each block chain exchanges data with the link data routing module through the corresponding block chain adapter; the link data routing module maps the data entity of each block chain into a unique ID, and the ID is used as the access address of the corresponding block chain in the cross-chain data routing; and the block chain adapters provide a data communication protocol conversion function for the connected block chain and link data routing module. According to the method, the technical problem that interconnection and intercommunication between heterogeneous block chains (systems) cannot be realized due to multi-dimensional heterogeneity such as a bottom-layer architecture, a data structure, an interface protocol and a security mechanism is solved through a block chain cross-chain technology, so that full-dimensional task process data can be provided, and multi-dimensional data cross validation is realized.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a task process traceability system based on blockchain cross-chain collaboration. Background technique [0002] The data in the blockchain-based electronic data storage system are all consensused by participating nodes, and are stored independently and backed up by each other. The ledger has the characteristics of being hard to lose and hard to tamper with. It records the data source, data time stamp, data transfer process, etc., and can be used to assist in the identification of the authenticity of electronic data. [0003] However, the existing blockchain-based electronic data storage system has the following defects: [0004] On the one hand, the existing blockchain-based electronic data storage system is limited by the single-chain architecture characteristics of the blockchain itself, and the single-chain architecture is difficult to meet the three requirements of high...
