Block generation method and device based on blockchain node network

Abstract

The embodiment of the invention relates to a block outputting method and device based on a block chain node network. The method comprises the following steps: generating a first block, and performing a first hash operation according to the first block to obtain a first hash value; signing the first hash value to obtain a first digital signature; performing a second hash operation on the second block to obtain a second hash value, wherein the second block is the next block of the first block; performing a third hash operation on the first digital signature and the second hash value to obtain a third hash value; and according to the third hash value and a preset random rule, selecting a second block outputting node from the plurality of block outputting nodes as an block outputting node of the second block. Therefore, the block outputting node can specify the next block outputting node, the specified process has certain randomness and verifiability, the probability that the block chain is attacked successfully can be reduced, the block outputting efficiency of the block chain node network is improved, and then the accounting efficiency is improved, so that the block chain node network can adapt to a service scene with a larger data scale.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for generating blocks based on a blockchain node network. Background technique [0002] Every node in the blockchain network is equivalent to every computer or server terminal that stores all block data. The production of all new blocks, as well as the verification and accounting of transactions, and broadcasting them to the entire network for synchronization are all done by nodes. [0003] Nodes are what we commonly call miners. The different computing power of each miner determines how much accounting power it can allocate and how much reward it can receive. [0004] The first-generation consensus mechanism of the blockchain is called POW, which is the proof-of-work consensus mechanism, commonly known as mining. In order to produce a new block, thousands of hash collision operations must be performed. And these calculations will consume a lot o...

After being voted and elected by all currency holders, the supernodes that finally obtain the right to bookkeeping can greatly reduce the waste of energy. However, since the operations are concentrated on the supernodes, the computing power of the supernodes is relatively high. , and the efficiency of super nodes directly affects the efficiency of bookkeeping, which leads to the weak ability of this method to deal with large-scale data, and the development is restricted
