Abstract
One or more implementations of the present specification provide a blockchain-based cross-chain data access method. An operation request of a target data is received from a node device of a blockchain of a multi-chain system, wherein the operation request of the target data comprises a URL for performing an operation on the target data, wherein the URL comprises information about an access path of the target data in the multi-chain system, and wherein the multi-chain system comprises a plurality of blockchains. The target data from a target blockchain is determined based on the information of the access path, and an operation is performed on the target data based on the operation request. A result of the operation is transmitted to the node device.
