Embodiment 1

[0042] This embodiment provides a cross-chain transaction system and method for consortium blockchains. The research objects of this embodiment are two consortium blockchains: the first consortium chain (CB 1 ), the second consortium chain (CB 2 ). This example will give CB 1 ,CB 2 The active cross-chain transaction method between them. Cross-chain transactions refer to users making transactions between two blockchains, that is, assets in CB 1 ,CB 2 The process of transferring back and forth between. At present, most cross-chain transactions are implemented by destroying corresponding assets on the first blockchain and creating / releasing corresponding assets on the second blockchain, which can be regarded as a special transaction on the blockchain. trade.

[0043] Such as figure 1 As shown, the main technical idea provided by this embodiment is: when a transaction Tx occurs on the first consortium chain 1 , the first consortium chain needs to provide the second conso...

Abstract

The invention relates to a cross-chain transaction system and method for an alliance block chain and a storage medium, the system comprises a cross-chain medium alternative pool and an alliance chaincross-chain processor, and the cross-chain medium alternative pool comprises a plurality of candidate nodes; the cross-chain medium alternative pool is configured to receive a cross-chain transactionrequest and select a candidate node as a cross-chain medium node M; the cross-chain medium node M is configured to perform a buyer alliance chain transaction and a seller alliance chain transaction respectively, the seller alliance chain transaction occurs before the buyer alliance chain transaction, and the buyer alliance chain transaction and the seller alliance chain transaction are generated based on a cross-chain transaction request; the alliance chain cross-chain processor is configured to receive and verify the information of the buyer alliance chain transaction, receive and verify theinformation of the seller alliance chain transaction, and then generate a signature and evidence. Compared with the prior art, the system and method has the advantages of safety, credibility of cross-chain transaction, diversity of applicable scenes and the like.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a cross-chain transaction system, method and storage medium for alliance block chains. Background technique [0002] The blockchain technology born together with Bitcoin integrates cutting-edge technologies such as distributed storage, consensus mechanism, peer-to-peer technology, and cryptography, and is serving as an important infrastructure for building the future value Internet. At present, the blockchain has become complete and mature in terms of single-chain function mining, and in terms of specific implementation and deployment types, the alliance chain is undoubtedly the underlying technology paradigm with the most commercial application value. In recent years, the construction of commercial alliance chain platforms has developed rapidly, and the blockchain applications built by various enterprises based on their own platforms are blooming. Then, after the f...
