Block generation method and device on blockchain

Abstract

The embodiment of the invention relates to a block outputting method and device on a block chain. 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; sending a first hash value to other nodes in the plurality of block outputting nodes; determining first numerical values of the pluralityof block outputting nodes; selecting a specified number of first numerical values according to the sizes of the first numerical values of the plurality of block outputting nodes; performing a secondhash operation on the specified number of first numerical values to obtain a second hash value; and according to the second hash value and a preset random rule, selecting a second block outputting node from the plurality of verification nodes as a block outputting node of a second block, the second block being a next block of the first block. Therefore, the block outputting node can assign the next block outputting node, the assigned process has certain randomness and verifiability, the probability that the block chain is attacked successfully can be reduced, the block output efficiency of theblock chain node network is improved, and then the accounting efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method and device for generating blocks on a 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 rights it can allocate and how many rewards 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. To produce a new block, thousands of hash collisions must be performed. And these operations will consume a lot of electricity, resulting in energ...

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
