Embodiment Construction

[0031] It should be noted that the transaction described in this manual refers to a piece of data created by the user through the client of the blockchain and needs to be finally published to the distributed database of the blockchain. A transaction is a data structure agreed in the blockchain protocol. To store a piece of data in the blockchain, it needs to be encapsulated into a transaction.

[0032] Transactions in the blockchain can be divided into transactions in a narrow sense and transactions in a broad sense. A transaction in a narrow sense refers to a value transfer issued by a user to the blockchain; for example, in the traditional Bitcoin blockchain network, a transaction can be a transfer initiated by a user in the blockchain. In a broad sense, a transaction refers to a piece of business data with business intentions released by the user to the blockchain; for example, the operator can build a consortium chain based on actual business needs, relying on the consorti...

Abstract

A data reading method and system based on multiple blockchain networks are disclosed. Map the data stored in the blockchains of at least two first-type blockchain networks to the blockchains of the second-type blockchain network, and for each first-type blockchain network, the first-type blockchain network At least one node in the blockchain network is managed by a designated management party, and at least one node in the second blockchain network is managed by the designated management party. Specifically, for any first-type blockchain network, each first-type deposit transaction to be constructed by the first-type blockchain network will also be obtained by the second-type blockchain network, and the second-type The blockchain network writes the second type of attestation transaction including the obtained transaction hash of the first type of attestation transaction into its own blockchain.

Description

technical field [0001] The embodiment of this description relates to the field of information technology, and in particular to a method and system for reading data based on multiple blockchain networks. Background technique [0002] With the development of blockchain technology, the mode of data storage based on blockchain network is gradually emerging. [0003] For example, in the field of copyright protection, it is possible to build a blockchain network for storing certificates of copyright works and copyright-related information of copyright works (such as copyright owner information, copyright authorization information, copyright transfer information, etc.). The user can submit the target work created by himself to any node in the blockchain network, and the node will construct a deposit transaction based on the user's user information and the target work and broadcast it to other nodes. Each node in the chain network will write the deposit transaction into the blockch...
