Embodiment 1

[0031]A large-scale aerospace simulation scientific research laboratory adopts the method of the present invention to manage the simulated data of aerospace experiments. More specifically, computers used for simulation calculations and scientific researchers with data access requests are added to nodes using computers to form private chains for experiments. Data Management and Use.

[0032] It specifically includes the following steps: time synchronization, data synchronization request release, blockchain broadcast, node verification, file transfer, and historical records; the synchronized files are large data files.

[0033] The time synchronization step specifically includes that each private chain has a time synchronization management node, and regularly synchronizes the time of each node inside the private chain. The timing step includes time synchronization frequency setting, and the setting method is manual setting or automatic setting. Certainly.

Abstract

The invention provides a node data synchronization method in a block chain, which is used for solving the problems of concurrently synchronizing large-scale data files of multiple nodes, and differentaccess rights and access order in the switching process of a private chain and a public chain. Through splitting of large data files, node s the private chain are stored in a specific format, a synchronization mechanism of private chain internal time management is adopted to ensure that access order of private chain internal node, the data synchronization request is issued by block chain broadcast of synchronization request, and the data transmission is controlled by key verification. The account books of each node are recorded according to the file for the request and the transmission record, so the traceability of the operation record is ensured. The security of the whole private link file storage is improved through the partitioned backup node storage of large files, and the file transfer mode of P2P is adopted to improve the transfer speed. The method is applicable to the field of large-scale file security management transmission and use.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for synchronizing node data in a block chain. Background technique [0002] Blockchain is a distributed ledger system composed of a series of data blocks generated using cryptography. Blockchain includes "blocks" and "chains". A block is a data structure that records transactions, and transaction records are verified transfer or mining records. Each data block contains all encrypted exchange information data in the system within a certain period of time, which is used to verify the validity of the information and generate the next block; the link refers to the link relationship between each block and the next block, thus forming blockchain. A block contains three parts: transaction information, hash hash formed by the previous block, and random numbers. The private keys of both parties to the transaction, transaction quantity, digital signature of electronic currenc...
