Problems solved by technology

[0004] However, the closed trust model of the blockchain prevents direct interaction between different chains, and the interoperability between the chains greatly limits the application space of the blockchain.

Embodiment Construction

[0043] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0044] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which the present invention belongs.

[0045] The data sharing system refers to a system for sharing data between nodes. The data sharing system may include multiple nodes, and the multiple nodes may refer to various clients in the data sharing system. Each node can receive input information during normal work, and maintain shared data in the data sharing system based on the received input information. In order to ensure...

Abstract

The invention provides a cross-chain exchange method and system. The method comprises the steps that a first user node uploads a first transfer block recording an exchange key hash value and first digital currency to a first block chain; and the second user node uploads the second transfer block recording the exchange key hash value and the second digital currency to the second block chain. The first user node can unlock a second transfer block on a second block chain through an exchange key set by the first user node to obtain second digital currency in the second transfer block; and after the second user node obtains the exchange key on the second block chain, the first transfer block on the first block chain can be unlocked through the exchange key, and the first digital currency in the first transfer block is obtained. Therefore, cross-chain exchange of the first digital currency in the hand of the first user node and the second digital currency in the hand of the second user node is safely and efficiently realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a cross-chain exchange method and system. Background technique [0002] A blockchain is a decentralized or at least partially decentralized data structure for storing transactions, and a blockchain network manages, updates and maintains one or more blockchains by broadcasting, verifying and confirming transactions, etc. A network of compute nodes. As described above, the blockchain network may be provided as a public blockchain network, a private blockchain network, or a consortium blockchain network. [0003] Under the development trend of Internet globalization, it is increasingly difficult for a single blockchain to meet the needs of various transaction services. In order to cope with the complex and changeable cloud computing transaction service challenges, some units have proposed the concept of cross-chain exchange, that is, to exchange funds on different blockchains...
