Embodiment 1
[0113] The first node enters the prevote (50, 100) phase, and triggers a timer to start counting when a predetermined condition is met.
[0114] If the duration counted by the timer is greater than or equal to the predetermined duration and the prevote (50, 100) stage is not left, the first node packs a valid voting set.
[0115] Among them, the valid voting set includes valid precommit votes of the first node greater than 2 / 3×N in the precommit (50, 99) phase (that is, the first valid vote in the above) and the first node in the prevote (50, 100) phase All valid prevotes for .
[0116] After the second node receives the valid voting set, 1. If the second node is in the prevote (50, 30) stage, the consensus of the second node is relatively slow, and the second node itself has not yet reached precommit (50, 99), because there is If the valid precommit vote is greater than 2 / 3×N, the second node can directly enter the precommit (50,99) stage; 2. If the second node’s own stage i...
Embodiment 2
[0122] The first node enters the precommit (50, 100) phase, and triggers a timer to start counting when a predetermined condition is met.
[0123] If the duration counted by the timer is greater than or equal to the predetermined duration and the precommit (50, 100) stage is not left, the first node packs the valid voting set.
[0124] The valid voting set includes: valid prevote votes greater than 2 / 3×N in the prevote(50, 100) phase and all precommit votes in the precommit(50, 100) phase.
[0125] After the second node receives the valid voting set, if the second node is in the prevote (50, 30) stage, the consensus of the second node is relatively slow, and the second node itself has not yet reached the prevote (50, 100) stage, then the second node End the current prevote(50, 30) stage and enter the prevote(50, 100) stage.
[0126] In the above two embodiments, when the second node receives a valid voting set, fast-forward from the 30th round of consensus to the 100th round ...

Abstract
The present invention discloses a block chain-based consensus method, device, equipment, and storage medium. The method is applied to the first node of the block chain. The method includes: entering the first round of R1 consensus In the first consensus stage, R1 is a natural number; when the predetermined condition is met, the timer is triggered to start counting; if the duration of the timer is greater than or equal to the predetermined duration, and remains in the first consensus stage of the R1 round of consensus, a valid vote is packaged set; wherein, the valid voting set includes a first valid voting set, and the first valid voting is used to prove that the first node enters the first consensus stage of the R1 round of consensus; broadcasting the valid voting set. Through the embodiments of the present invention, consensus efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of block chains, and in particular relates to a consensus method, device, equipment and storage medium based on block chains. Background technique [0002] Blockchain is a decentralized distributed ledgersystem, which can be used to register and issue digital assets, property certificates, points, etc., and transfer, pay and trade in a peer-to-peer manner. Compared with the traditional centralized ledger system, the blockchainsystem has the advantages of being completely open, tamper-resistant, and preventing multiple payments, and does not rely on any trusted third party. [0003] Due to the high network delay in the peer-to-peer network, the sequence of transactions observed by each node cannot be completely consistent. Therefore, the blockchain system needs to design a mechanism to achieve consensus on the order of transactions that occur within a similar period of time. This algorithm for reaching a consensus ...
