Problems solved by technology
In the blockchain system under the existing DPOS consensus mechanism, the selection of block production nodes is realized through voting. However, because voters cannot observe the production block status of each node at all times, they do not vote in time, and the default is to follow the previous one. Vote according to the voting results, or vote for nodes that are often offline

The invention provides a consensus mechanism implementation method of a blockchain system. The method comprises the following steps: creating a system node weight table; parsing a broadcast block synchronization packet issued by a production node of a previous block in the blockchain system; enquiring the ip address of each node according to the system node weight table, subtracting 1 from a nodeweight value of an offline node, adding 1 to the node weight value of an online node, updating the system node weight table, and processing the node weight value corresponding to the ip address of each node in the system node weight table to obtain a total weight value L and a weight probability axis; and generating a random number r according to values 1 to L, and confirming the production node of the next block by judging a node weight value interval where the random number r is located. Therefore, according to the consensus mechanism implementation method provided by the invention, by obtaining the weight probability axis, the probability of the node with longer online time to become a block producer is the highest, so that the possibility that the frequently offline node becomes the block producer is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of information processing, in particular to a method, medium, device and system for realizing a consensus mechanism of a block chain system. Background technique [0002] The blockchain is essentially a deterministic state machine driven by transactions. Consensus is the process of agreeing on a deterministic transaction order and filtering invalid transactions. The compelling security of DPOS comes from its selection of block producers and the quality of verification nodes algorithm. In the blockchain system under the existing DPOS consensus mechanism, the selection of block production nodes is realized through voting. However, because voters cannot observe the production block status of each node at all times, they do not vote in time, and the default is to follow the previous one. Vote according to the voting results, or vote for nodes that are often offline. Contents of the invention [0003] The...
