A credible transfer method of cross-chain assets based on DID and VC

The distributed network structure of blockchain coincides with the market-oriented structure of distributed renewable energy. Blockchain technology can be used to synchronize the real-time price of grid services with real-time phasor control systems to balance microgrid operation, distributed power generation system access, and wholesale market operation. Distributed shared energy networks constructed in different regions and regions carry digital assets of different values. How to realize the credible exchange of energy digital assets across regions is an urgent need facing the current energy interconnection network. At present, there have been many researches on cross-chain asset exchange methods in the blockchain, such as: hash time lock, notary, side chain and so on. However, these asset exchange methods lack proper supervision (KYC&AML) and are inefficient. This article combines distributed digital identities (hereinafter referred to as DID) and verifiable credentials (VC) to propose a DID-based trusted cross-chain asset transfer method.
