specific Embodiment 1

[0068] A multi-party cross-chain method based on mirror cross-chain, which uses distributed oracles to map the value of multi-party assets, forms corresponding mirror assets and stores them in smart contracts, and responds to cross-chain requests to call smart contracts to carry out transfer transactions of mirror assets, realizing the chain of all things Uplink, such as figure 1 As shown, it is the overall structure diagram of the multi-party cross-chain method based on mirror cross-chain. Multi-party assets include digital currency Token, US dollar USD, gold Gold, education assets, medical assets, real estate, energy assets, etc. These assets are passed through the distributed oracle machine The price is copied to synthesize the corresponding mirror assets, which are stored in the smart contract of the transaction circulation chain, and the user calls the smart contract on the chain to realize the cross-chain of multi-party assets.

[0069] Such as figure 2 As shown, the m...

Embodiment 2

[0099] In the present invention, a multi-party cross-chain system based on mirror cross-chain includes: creation module, association module, update module and conversion module, and account module, mirror asset module, oracle module, list management module, browser module; through Modular design makes this multi-party cross-chain method form an effectively operating multi-party cross-chain system;

[0100] Among them, the creation module is used to create the transaction circulation chain and deploy the smart contract;

[0101] The association module is used to associate the smart contract with the distributed oracle machine, and through the distributed oracle machine, the required assets are synthesized into corresponding mirror assets and transmitted to the smart contract on the chain;

[0102] The update module listens to the distributed oracle nodes through the smart contract, records the mirrored assets in real time, creates and updates the multi-party mirrored asset list...

Abstract

The invention discloses a multi-party cross-chain method and system based on mirror image cross-chain, and the method comprises the steps: carrying out the multi-party asset value mapping through employing a distributed oracle machine, forming corresponding mirror image assets, storing the mirror image assets in a smart contract, responding to a cross-chain request, calling the smart contract to carry out the circulation transaction of the mirror image assets, and achieving the intercommunication of everything chains. According to the method, a distributed oracle machine is used for real-time image asset synthesis, the accuracy of image asset synthesis is ensured, an intelligent contract is used for monitoring an oracle machine node network in real time, collecting image assets of multi-party assets and increasing a dynamic multi-party image asset list, and a modular design is adopted, so that efficient and rapid cross-chain transaction of the multi-party assets is realized; and the block chain cross-chain technology landing entity economy is accelerated.

Description

technical field [0001] The invention belongs to the technical field of block chain cross-chain, and in particular relates to a multi-party cross-chain method and system based on mirror image cross-chain. Background technique [0002] As a distributed ledger technology, blockchain can be applied in many fields such as finance, health care, supply chain, asset management, etc. However, it is restricted by factors such as throughput, network isolation, supervision, and scalability. Blockchain projects cannot serve commercial applications very well, especially for various physical assets under the chain, and it has always been impossible to conduct multi-party asset transactions on the chain. Among the many problems faced by the blockchain, the isolation of the network hinders the collaborative operation between different blockchains, which greatly limits the space for the blockchain to play. Cross-chain technology is the key to realizing the value Internet. At present, most as...
