Problems solved by technology

If the block generation time is too slow, the uplink confirmation speed of transaction data will be slow and the business performance will be poor
However, if the block generation time is too fast, there will be a block chain bifurcation caused by block generation failure, and transaction data rollback will easily occur, causing troubles to the business layer

Abstract

The embodiment of the invention discloses a block generation method, device, equipment and storage medium. The method includes: obtaining the initial block generation time of the local node in this block generation cycle, wherein the initial block generation time is determined according to the block generation cycle of the previous block generation node and the transition time between nodes ; After detecting the arrival of the initial block generation time of the local node, a new block is generated according to the block generation rules within the node. In the embodiment of the present invention, when the block generation node is switched, the node transition time is increased between adjacent switching nodes, so that even if the block generation time within the node is shortened according to the block generation rules within the node, the node can also be generated for the previous block The generation of middle and tail blocks and the transmission to the blockchain network provide sufficient time. In the case of shortening the block generation time of nodes and increasing the confirmation speed of blocks, the probability of blockchain bifurcation is reduced and the previous block is avoided. Tail blocks are discarded in generator nodes.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of block chains, and in particular, to a block generation method, device, device, and storage medium. Background technique [0002] With the continuous development of Internet technology, a decentralized and transparent blockchain technology has emerged. Blockchain technology uses data blocks to break the current Internet's dependence on central servers. All data generated in the network will be recorded by block generation nodes, and through data broadcast and verification by other nodes to form new blocks And uploaded to the end of the blockchain. After the block on the chain is confirmed, the new block is permanently recorded in the block chain; otherwise, for blocks that cannot be confirmed, the data in the block will be rolled back. [0003] In the existing technology, from the perspective of versatility, no matter what consensus mechanism and parameter deployment method is adopt...
