Embodiment 1

[0052] 1) Blockchain uses DPoS consensus

[0053] Using the DPoS consensus, the number of block producers selected by voting is determined. For example, the number of block producers selected by EOS is 21, which cannot exceed this number. The normal operation of the blockchain requires less than 1 / 3 of the nodes to be evil. Relying on the normal operation of more than 2 / 3 of the producer nodes ensures the normal operation of the chain.

[0054] The same block producer that needs to be used by the two chains across the chain, that is, the block producer elected by the A chain, is also the block producer of the B chain. The list of block producers generated by chain A can be sent to chain B through the network. That is, chain A and chain B share a set of block producers.

[0055] As long as more than 2 / 3 of the block producers vote, they can determine the behavior on the blockchain. Block producers have the right to manage the blockchain. For example, the contract upgrade o...

Abstract

The invention discloses a cross-chain transaction method, a cross-chain transaction system and a computer readable storage medium. The cross-chain transaction method is characterized in that for two block chains based on DPoS consensus, the two block chains have a public block producer, a user in one block chain initiates a transaction, and after the transaction is audited and voted by a block producer, funds in an account on one block chain can be transferred to an account of the other block chain in a cross-chain manner. The cross-chain transaction method and system and the computer readablestorage medium are easy to implement, and the cross-chain transaction is simple and convenient.

Description

technical field [0001] The present invention relates to a cross-chain transaction method, system and computer-readable storage medium, and the present invention can be applied to the cross-chain of block chains based on DPoS consensus. Background technique [0002] Explanation of technical terms [0003] Delegated Proof of Stake (DPoS): DPoS is a system in which a fixed number of selected entities (called block producers or witnesses) are chosen to create blocks in a round-robin order. [0004] Block producers are voted on by network users, each of whom gets votes proportional to the amount of tokens they own on the network (their stake). [0005] Alternatively, voters can choose to delegate their stake to another voter, and the delegated voter will vote on their behalf for block producers using DPoS consensus to represent the blockchain system EOS. [0006] Cross-chain [0007] It refers to the transfer of digital assets from one blockchain to another. [0008] The curr...
