Problems solved by technology

However, in the cross-chain interaction, on the one hand, the states between the chains are not synchronized with each other. If the consensus protocols adopted inside the chains are different, the internal consensus state of the nodes cannot be used as a sign of transaction submission.
However, cross-chain interaction needs to obtain transaction and status data between chains, so transaction guarantee in the process of cross-chain interaction has become an important technical challenge point

Abstract

The invention discloses a method for guaranteeing the consistency of cross-blockchain transactions of a blockchain, and the method achieves the cross-blockchain operation through the proxy node of theblockchain, achieves a decentralized cross-blockchain scheme through registration management, is substantially different from a mode of a relay blockchain or a notarian, and meets the demands of thedecentralized management of the blockchain. In order to ensure the consistency of cross-blockchain transactions, a cross-blockchain transaction lock scheme is designed and comprises transaction locking, transaction submission rollback and other processes, and a distributed transaction mechanism is realized in combination with a hash time lock; the transaction locking function is realized in combination with a smart contract, when the cross-blockchain transaction interface is realized, the transaction locking capability is packaged as the underlying capability, and a user does not need to manually process a transaction control contract during cross-blockchain operation, so that the usability and the stability are improved, and the error probability is reduced. The invention further providesa data integrity and existence design.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for ensuring the consistency of cross-chain transactions of block chains. Background technique [0002] With the development of blockchain, the demand for value exchange and operation between different blockchains has become increasingly strong. The value exchange between cross-blockchains must be based on equivalent value exchange without damage as a prerequisite. Therefore, cross-blockchain operations need to solve: [0003] 1. Avoid the centralization of value exchange operations and prevent deliberate forgery and tampering. [0004] 2. To avoid the loss of value assets, users exchange value across blockchains. Users transfer value assets on one chain with the purpose of obtaining assets of equivalent value on another chain. When there is no operation on the latter blockchain If it is successful, it is necessary to roll back the operation of the previous block...
