Description

Private blockchain operation support system supporting logical multi-chain and its working method

technical field

The invention relates to a private block chain operation support system supporting logical multi-chains and a working method thereof.

Background technique

The blockchain is the underlying technology of Bitcoin. It is essentially a decentralized database. The database is open and cannot be tampered with, and there is no central point. Once the data is included in the blockchain, everyone can query and verify it. Whether the data exists. The blockchain uses cryptographic methods to correlate data blocks, and each data block contains the information of a data transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. The blockchain realizes the non-tamperable modification of data through cryptography, P2P network, and decentralized consensus mechanism. The blockchain is suitable for any business and service electronic data credible issues. The early application areas are mainly digital currency, and gradually transition to more industry applications as the development matures, such as smart contracts, securities transactions, e-commerce, IoT, social messaging, file storage, proof of existence, identity verification, equity crowdfunding.

The blockchain is divided into a public blockchain and a private blockchain. The public blockchain is oriented to the Internet field. Multiple pre-selected nodes are designated by an open group as data writers. Each block is generated by all The pre-selected nodes jointly decide, and anyone else can make limited queries through the open API of the blockchain. The private blockchain uses blockchain technology to build a distributed blockchain platform within the organization. The builder can be a company or an individual, who has exclusive access to write to the blockchain. In the application scenario of the public chain, the blockchain needs to mainly solve currency applications, support currency and automatic transactions, and emphasize distributed and open design. Currently, they are all single-chain applications. Considering the needs of data security and privacy, many enterprises need to build a blockchain platform within the enterprise that is only used by the enterprise. Currently, the private blockchain follows the technical model of the public chain, and the implementation is a single-chain model. However, within the enterprise, the business is divided into sections, each business is responsible for one system, and each business system is relatively independent. Only using the single-chain mode to record data requires recording all kinds of irrelevant business data on the same chain. This leads to confusion of data content on the chain, difficulty in management, and inconvenient data traceability on the blockchain, which affects data credibility and thus loses the purpose of adapting to blockchain technology.

The technical problems that need to be solved urgently in the existing technology are: how to carry out trusted storage of various key data within the enterprise, and how to carry out convenient and clear classification management of key data of different businesses.
