Problems solved by technology

[0004] However, the blockchain involves a "51% attack" scenario, that is, a node or multiple nodes with more than 51% computing power in theory can conduct a "51% attack" on the blockchain, hindering the normal operation of the blockchain, Destruction of blockchain data
At present, with the growth of the computing power of a single node, a single or a small number of nodes can have a huge computing power. In this way, when the computing power of each node in the entire blockchain network varies greatly, a "51% Attack" conditions are not difficult to achieve, threatening the security of the blockchain network

Abstract

A block generating method and device and a block chain network are disclosed for improving safety of a block chain. The method comprises the following steps of signing a block generated by the block generating means based on the private key information of the block generating means to obtain a signature block; and issuing the signature block to the signature block through the first node device in the block chain network Other node devices.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block generation method, device and block chain network. Background technique [0002] Blockchain technology is a distributed, decentralized, and trustless network data consensus storage technology, which realizes distributed computing based on a unique block (Block) generation mechanism and a P2P (Point to Point, point-to-point) network communication mechanism synchronization problem. [0003] Generally speaking, during the formation of the blockchain, every node participating in the calculation enjoys the same authority, including the authority of transfer (Transaction), calculation block and so on. In the existing technology, the computing power of the nodes participating in the block calculation is uneven. In order to improve the probability of generating blocks, the hardware used by the nodes for calculating the blocks is also changed from CPU (Central Proces...
