Problems solved by technology

[0004] The current mainstream cross-chain technology includes notary mechanism, relay and hash lock technology. The whole process of notary technology is to trust the notary node. The disadvantage is that you need to trust one or more entity nodes, and it does not support multi-coin Smart contracts need to rely on similar centralized notaries to verify signatures for cross-chain transactions for a long time; while the application of the relay chain is relatively narrow, it must be ensured that there are relays on each chain, otherwise only one-way cross-chain is supported; and the simple Hash-locked cross-chain transactions are currently only suitable for transfer transactions between public chains, and there are transaction risks such as malicious transactions and incomplete transactions

Embodiment Construction

[0026] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The asset cross-chain transaction method between blockchains of the present invention simply means that the first user uses the second asset in the second blockchain to exchange the first asset of the second user in the first blockchain through cross-chain, To achieve cross-chain asset exchange, the first block chain and the second block chain are not limited to public chains and public chains, but also include alliance chains and public chains, alliance chains and alliance chains, assets are not limited to digital currencies, but also digital Assets, physical assets, and other types of assets that can be chained; the specific implementation process of the asset cross-chain transaction method is as follows:

[0028] (1) The first user initiates a c...

Abstract

The invention discloses an asset cross-chain transaction method between block chains. Cross-chain asset exchange is realized through an asset two-way lock and a cross-chain contract verification transaction; The invention provides a decentralized point-to-point cross-chain transaction scheme. Transfer between the digital currency and the digital currency is realized between the public chain and the digital currency, transfer between the digital currency or the physical asset and the digital currency is realized between the alliance chain and the public chain, and exchange and transfer betweenthe physical asset and the physical asset are realized between the alliance chain and the alliance chain. Therefore, the cross-chain transaction method is suitable for various common block chain typesand realizes conversion and transaction of various assets.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method for asset cross-chain transactions between block chains. Background technique [0002] In 2008, a scholar named "Satoshi Nakamoto" published the paper "Bitcoin: A Peer-to-Peer Electronic Cash System", laying the foundation for blockchain technology. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures a non-tamperable and non-forgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate update data, uses cryptography to ensure data transmission and access security, and uses automated script codes to A new distributed infrastructure and computing method for programming and manipulating data through intelligent contracts. With...
