Block output method and device of block chain

Abstract

The embodiment of the invention relates to a block output method and device relating to a block chain. The method comprises: if a generated first block is larger than a first threshold value, dividing the first block into a first sub-block and at least one second sub-block; performing a first hash operation according to the first block to obtain a first hash value; determining second hash values of the plurality of outblock nodes; selecting a specified number of second hash values according to the sizes of the second hash values of the plurality of outblock nodes; performing fourth hash operation on the specified number of second hash values to obtain a fourth hash value; and according to the fourth hash value and a preset random rule, selecting at least one second block-out node from the plurality of block-out nodes as a block-out node of the at least one second sub-block. Therefore, the block-out node can assign the next block output node, the assigned process has certain randomness and verifiability, and the block output efficiency and accounting efficiency of the block chain node network are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block generation method and device related to blockchain. 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...

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
