Abstract
One or more implementations of the present specification relate to blockchain-based cross-chain data access methods and apparatuses, and electronic devices. An access request that is specific to target data and that is sent by a node device is obtained. The target data is stored in a target blockchain of a multi-chain system that comprises a plurality of blockchains. The access request comprises an access path of the target data. The target blockchain that the target data is located in is determined based on the access path of the target data. A corresponding data access driver configured for the target blockchain is determined based on the access path of the target data. The data access driver is invoked to parse the access request and to access the target data.
