Method and device applied to block chain packaging

Abstract

The embodiment of the invention relates to a method and device applied to block chain packaging. The method comprises the following steps: determining a first digital signature of a specified number of outblock nodes and a first digital signature of the first outblock node, the first digital signature of each outblock node being obtained by signing a first hash value through the outblock node, andthe first hash value being obtained by performing a first hash operation according to a first block; performing a second hash operation on the first digital signature of the specified number of outbound nodes and the first digital signature of the first outbound node to obtain a second hash value; and according to the second hash value and a preset first random rule, selecting a second block-outnode from the plurality of block-out nodes as a block-out node of a second block. Therefore, the block outlet node can specify the next block outlet node, the specifying process has certain randomnessand 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 packaging method and device applied 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 in was...

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
