摘要
Disclosed are methods and systems for recording data based on a plurality of blockchain networks. Data recorded in blockchains of at least two first-type blockchain networks is mapped to a blockchain of a second-type blockchain network. At least one node in each first-type blockchain network is managed by a designated manager, and at least one node in the second-type blockchain network is managed by the designated manager. Specifically, each first-type blockchain transaction constructed by any first-type blockchain network can also be obtained by the second-type blockchain network, and the second-type blockchain network writes a second-type blockchain transaction including a transaction hash of the obtained first-type blockchain transaction, into the blockchain of the second-type blockchain network.
