Embodiment Construction

[0044] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0045] First of all, some nouns involved in this application are introduced:

[0046] Public chain (or public blockchain): refers to a blockchain that can be read by anyone, anyone can send a transaction and the transaction can be effectively confirmed, and anyone can participate in the consensus verification process.

[0047] Moore chain: Directed Acyclic Graph (DAG) public chain free of transaction fees, the fastest transaction confirmation speed can reach 50 milliseconds (of course, it can also be a value larger or smaller than 50 mm), subject to Limited by bandwidth and network latency.

[0048] Ethereum: refers to an open source public blockchain platform with smart contract functions,...

Abstract

The invention relates to a cross-chain transaction method and device on a block chain and a storage medium, and belongs to the technical field of block chains, and the method comprises the steps: monitoring a second contract account on a third-party public chain through at least two first contract accounts on a mole chain; when the mole chain monitors that the second contract account receives a transaction request sent by the first external account, creating a second transaction resource equivalent to the first transaction resource indicated by the transaction request on a target contract account of the mole chain; the target contract account transfers the second transaction resource to a second external account corresponding to the mole chain; when the second external account initiates atransaction request, the second external account transfers the second transaction resource to the target contract account; Triggering the second contract account to carry out transaction according tothe transaction record on the target contract account; the technical problems that an existing cross-chain transaction needs to consume extra transaction expenses and the transaction time is long canbe solved. The transaction cost of the cross-chain transaction is saved, and the transaction duration of the cross-chain transaction is shortened.

Description

technical field [0001] This application relates to a cross-chain transaction method, device and storage medium on a block chain, and belongs to the field of block chain technology. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database. The blockchain is a series of data blocks associated with each other using cryptographic methods. Each data block contains information about a blockchain network transaction, which is used to verify the validity of the information and generate the next block. [0003] Cross-chain transactions refer to transaction operations between multiple blockchains, and cross-chain transactions are bridges that connect scattered blockchain islands. [0004] At present, when two blockchains conduct cross-chain transactions, the exchange between tokens include...
