Abstract
One or more implementations of the present specification provide a blockchain-based cross-chain data access method. An access request corresponding to target data is received from a node device of a blockchain. The access request includes an access path of the target data in a multi-chain system consisting of a plurality of blockchains, and the access path indicates a target blockchain that stores the target data in the plurality of blockchains. The target data from the target blockchain is determined based on the access path. The target data is transmitted to the node device.
