Problems solved by technology
But it also has some problems: the participation of witness nodes in the whole system is not high, because participation in voting and consensus requires some resource consumption; They are eliminated; there is also a DPoS algorithm that only distributes bookkeeping incentives to entrusted nodes after completing the bookkeeping, and does not reward those voting witness nodes, which will intensify the centralization trend of the blockchain system in the long run

Embodiment Construction
[0078] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, only a part of the embodiments of the present invention, not all the embodiments, and are not intended to limit the present invention.
[0079] The block chain consensus method proposed by the embodiment of the present invention has been improved on the current DPoS algorithm, refer to figure 1 , shows a flow chart of a blockchain consensus method based on a delegated proof-of-stake algorithm in an embodiment of the present invention. The blockchain includes: a plurality of witness nodes; the blockchain consensus method based on a delegated proof-of-stake algorithm includes:
[0080] Step 101: Each witness node among ...

The present invention relates to a block chain consensus method and device based on a delegated equity proof algorithm, and relates to the block chain field. Vote and select multiple entrusted nodes; issue voting incentives to the nodes participating in the voting consensus after confirming the validity of the ballots; any entrusted node among the multiple entrusted nodes generates a block, and after the block consensus is successful, vote Issue bookkeeping incentives to the witness nodes whose votes are valid for the corresponding entrusted nodes. The present invention reduces the importance of coin age, can speed up the elimination of wrong witness nodes, issues voting incentives to witness nodes with valid votes, and improves the participation of witness nodes. After the block consensus is completed, the witness nodes with valid votes will be issued accounting incentives to avoid the trend of centralization of the blockchain system, which has high practicability.
Description
technical field [0001] The invention relates to the field of block chains, in particular to a block chain consensus method and device based on a delegated equity proof algorithm. Background technique [0002] Blockchain technology is a decentralized recording technology formed by combining various existing technologies (P2P network, cryptography, etc.). At present, there is no unified definition of blockchain. The definition of blockchain on Wikipedia is: blockchain (bolckchain) is a peer-to-peer network that uses distributed databases to identify, disseminate and record information. In short, blockchain Block chain is essentially a distributed database with decentralized characteristics. Block chain technology is essentially a distributed database technology. Nodes in the network use cryptography, consensus algorithms, point-to-point communication and other technologies to jointly Maintain the consistency and integrity of the entire network data. [0003] At present, the ...
