Method and device for producing blocks based on block chain

Abstract

The embodiment of the present invention relates to a block chain-based method and device. Including: if the generated first block is greater than the first threshold, dividing the first block into a first sub-block and at least one second sub-block; determining the first digital signatures and The first digital signature of the first block producing node; performing a second hash operation on the first digital signatures of the specified number of block producing nodes and the first digital signature of the first block producing node to obtain the second Hash value; according to the second hash value and the preset first random rule, select a second block generation node among the plurality of block generation nodes as the block generation of the at least one second sub-block node. In this way, the block producing node can designate the next block producing node. The designation process has a certain degree of randomness and verifiability, which can reduce the possibility of the blockchain being successfully attacked and improve the block production of the blockchain node network. efficiency.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based method and device. 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 of power, resulting in waste of energy, ...

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
