Embodiment Construction

[0085]The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

[0086]This application relates to blockchain related technologies. Among them, the blockchain refers to a set of decentralized and distributed storage infrastructure. Specifically, it is a data structure composed of data blocks in a chronological order in a manner similar to a linked list, which can be safely stored in a prioritized manner. , The data can be verified in the system, and the data can not be tampered with or forged by means of cryptography. There can be multiple blockchain nodes in a blockchain, and the multiple blockcha...

Abstract

The invention discloses a cross-chain transaction method and device based on a block chain and a computer readable storage medium. The method comprises the steps that a first node acquires a cross-chain transaction data packet and tree root proof information which are sent by a relay node and aim at target transaction data, wherein the cross-chain transaction data packet and the tree root proof information are sent to the relay node by a second node, the first node belongs to a first service block chain, the second node belongs to a second service block chain, the cross-chain transaction datapacket comprises a target Merkel tree root and a consensus signature set of a block to which the target transaction data belongs, and the consensus signature set is obtained after consensus of the cross-chain transaction data packet is passed; verifying the consensus signature set, and verifying the target Merkel tree root according to the tree root proving information; and when the consensus signature set and the target Merkel tree root are successfully verified, executing a transaction service associated with the target transaction data. By adopting the method and the device, the reliabilityof the cross-chain transaction between the first service block chain and the second service block chain can be improved.

Description

Technical field[0001]This application relates to the technical field of data processing, in particular to a blockchain-based cross-chain transaction method, device, and computer-readable storage medium.Background technique[0002]Blockchain technology uses block-chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligence composed of automated script codes. A new distributed infrastructure and calculation method in which contracts are used to program and manipulate data. Simply put, the blockchain is a decentralized distributed ledger.[0003]In the prior art, in the process of realizing cross-chain transactions between the first blockchain and the second blockchain, it is usually implemented based on smart contracts, that is, the first blockchain and the second blockchain can be Rules and protocols related to cross-chain transactions...
