Block output method and device based on block chain

Abstract

The embodiment of the invention relates to a block output method and device based on a block chain. The method comprises the steps that if a generated first block is larger than a first threshold value, the first block is divided into a first sub-block and at least one second sub-block; a first digital signature of a specified number of block output nodes and a first digital signature of the firstblock output node are determined; a second hash operation is performed on the first digital signature of the specified number of block output nodes and the first digital signature of the first blockoutput node to obtain a second hash value; and according to the second hash value and a preset first random rule, a second block output node is selected from the plurality of block output nodes as a block output node of the at least one second sub-block. Therefore, the block outlet node can specify the next block outlet node, the specifying process has certain randomness and verifiability, the probability that the block chain is attacked successfully can be reduced, and the block outlet efficiency of the block chain node network is improved.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based block generation method and device. Background technique [0002] Each 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 many bookkeeping rights it can allocate and how many rewards it receives. [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 collision operations must be performed. These calculations consume a lot of power and cause energy waste, so they are also ...

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
