Embodiment Construction

[0047] Many technical details are provided in the following exemplary descriptions to enable readers to better understand the ideas and achieved effects of the present invention. But all the changes and modifications not limited to the following details, based on the realization of the idea of ​​the present invention, are the technical solutions required by the claims of this application.

[0048] First of all, whether it is data storage or data transmission, the block height must exist as an identifier, and every link of the implementation plan includes the transmission of the block height.

[0049] Secondly, the network data is transmitted in Json format, and the Json object contains height information.

[0050] During the block synchronization process, whether it is a thread-safe queue to be synchronized or some intermediate data, it can be stored directly in memory, or using a third-party caching tool such as redis for storage.

[0051] According to the Byzantine algorith...

Abstract

The invention relates to a blockchain block synchronization technology, and particularly relates to a parallel block synchronization method for blockchain nodes. The method is characterized by including the following aspects: (1) determining a height range of synchronization, and putting the height range into a memory queue; (2) enabling an asynchronous thread to regularly obtain the block heightto be synchronized from the memory queue, and sending block synchronization requests to other nodes; (3) enabling the nodes that receive the block synchronization requests to take out the local corresponding data, and sending the data to the nodes that request synchronization; (4) enabling the nodes to collect the block information returned by other nodes, and judging whether the block informationneeds to be stored by consensus; and (5) if the synchronization is successful, deleting a mark to be synchronized of the height, and if the synchronization is not successful, putting back the heightinto the memory queue. The invention provides the parallel block synchronization method for the blockchain nodes, the blocks and transaction information that have a node missing phenomenon or need tobe updated can be synchronized in time without affecting the normal consensus and a block building process of a blockchain, and the continuity and integrity of blockchain data can be ensured; and by using a parallel technology, the original transaction processing speed can be guaranteed, and thread resources of a computer can be fully utilized.

Description

technical field [0001] The invention relates to a blockchain block synchronization technology, in particular to a parallel block synchronization method for blockchain nodes. Background technique [0002] In the blockchain system, we mark the position of a block in the chain as the height of the block. In a normally running blockchain system, block data corresponding to the same height in different blockchain nodes should be completely consistent. [0003] The block building process of the blockchain system based on Byzantine consensus roughly includes the following four stages: [0004] (1) The node collects transaction information and broadcasts the hash value of the transaction to all other nodes; [0005] (2) All nodes will take the intersection of the collected transaction hash value sets, and the obtained public transaction set will be used as the transaction set for this block building. The selected block building nodes will build the block and broadcast the block in...
