Abstract
The embodiments of the disclosure disclose a method and system for cross-chain transfer of data based on decentralized identifiers. According to the disclosure, after receiving a data transfer transaction sent by a terminal of an original holder, a source chain reads a public key of the original holder in a corresponding first BID document according to a first BID carried by the data transfer transaction, and verifies a signature carried by the data transfer transaction. After the signature passes verification, the source chain initiates a cross-chain transaction. In response to the cross-chain transaction, a target chain deploys a second BID document in the target chain, and a public key of a new holder and data to be transferred are recorded in the second BID document. Further, the source chain replaces the public key of the original holder in the first BID document with the public key of the new holder.
