Blockchain cross-chain interaction method and system

Abstract

The embodiment of the invention provides a blockchain cross-chain interaction method and system, and belongs to the technical field of blockchains. The method comprises the following steps that a client registers each timing task of each application and transmits a registration result to a main chain; after the main chain monitors that the target timing task is linked on the main chain, a task linking notification is initiated, and the task linking notification is used for indicating the transaction state of the target timing task on the main chain and linking the target timing task; a side chain acquires and executes a target timing task from the main chain in a cross-chain data transmission mode; the side chain modifies the state of the target timing task into a stop state, and synchronously updates the stop state of the executed target timing task to the main chain in a cross-chain data transmission mode; and the target timing task is ended on the main chain and the side chain. Through the scheme of the invention, the purposes of unified management and concurrent control of timing tasks of multiple applications by the main chain system and the overall transaction performance ofthe main chain node are improved, so the user-oriented performance is more optimized.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain cross-chain interaction method and system. Background technique [0002] Blockchain is a new type of decentralized protocol, which can safely store digital currency transactions or other data. The information cannot be forged and tampered with. The transaction confirmation on the blockchain is completed by all nodes on the blockchain. The consensus algorithm To ensure its consistency, a public ledger is maintained on the blockchain, and the public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. [0003] The interaction between blockchain chains is an important part of cross-chain design. Currently, the scalability design of blockchain mainly serves the single-chain transaction process. For the expansion of cross-chain transactions, most of them are based on the model of heterogeneous chains. ...

[0003] The interaction between blockchain chains is an important part of cross-chain design. Currently, the scalability design of blockchain mainly serves the single-chain transaction process. For the expansion of cross-chain transactions, most of them are based on the model of heterogeneous chains. In order to serve For heterogeneous chains, the scheme design is too complicated, and under the premise of ensuring the function, the efficiency cannot be guaranteed

[0004] In the existing blockchain technology, on the one hand, due to the relatively low transaction performance of the existing blockchain platform, the transaction processing speed is slow, which cannot meet the needs of users for frequent transactions and transaction timeliness; on the other hand, each blockchain platform Different business contracts are used between them, and it is impossible to perform a large number of high-frequency transactions on a blockchain platform
