Method for cross-blockchain data migration

Method for cross-blockchain data migration

Cross-blockchain data migration method:

Method overview: The method is executed by the first node in the first blockchain network, including obtaining the first mode business data from the first blockchain, converting it into the second mode business data of the second blockchain, establishing a hash mapping relationship, and migrating it to the second node.

Hash mapping relationship: A hash mapping relationship between the first business data information and the second business data information is established on the first blockchain to quickly find and migrate data.

Data encryption migration: During the migration process, the second business data information is encrypted using the public key of the second node to ensure the security of the data during transmission.

Data migration device:

Device module: The device includes a first acquisition module, an acquisition conversion module, an establishment module, and a migration module, which are respectively responsible for obtaining data from the first blockchain, converting data mode, establishing a hash mapping relationship, and migrating data.

Encryption and decryption: The migration module also includes an encryption unit and a migration unit for data encryption and migration; the receiving module includes a decryption unit for receiving encrypted data and decrypting it.

Node device and storage medium:

Node device: A specific implementation of the node device is provided, including a processor, a memory, and a network interface for executing the cross-blockchain data migration method.

Storage medium: A computer-readable storage medium stores a computer program for executing a cross-blockchain data migration method, ensuring that the method can be run on different computing devices.

Data processing system:

System composition: The data processing system includes a data processing device running on a first node and a second node to achieve cross-blockchain data migration and processing.

Collaborative work: The first node and the second node work together through a hash mapping relationship and a data encryption mechanism to ensure efficient and secure data migration.
