AI Technical Summary

Technical Problem

Existing migration solutions for blockchain systems such as consortium blockchains require business shutdowns and cannot achieve online hot migration, resulting in low migration efficiency.

Method used

By adapting the original certificate of the target blockchain, a first adapted certificate is generated, granting it the system permissions of the source blockchain. Data is then transferred to the target blockchain via replication, while maintaining the service of the source blockchain during the data transfer process. After completion, the target blockchain is configured with a certificate to achieve access control.

Benefits of technology

It enables smooth and efficient hot migration of blockchain systems such as consortium blockchains, avoiding business interruptions during the migration process and improving migration efficiency.

Abstract

This application discloses a data migration method and electronic device. The method adapts the original certificate of the target blockchain to obtain a first adapted certificate for the target blockchain. Based on this first adapted certificate, the target blockchain gains system permissions from the source blockchain. Using these permissions, the method transfers data from the source blockchain to the target blockchain via replication, maintaining the services of the source blockchain during the transfer. After the transfer is complete, the method further configures the certificate on the target blockchain to obtain a target certificate for access control when providing subsequent blockchain services. By performing adaptation processing on the original certificate of the target blockchain, this application grants the target blockchain system permissions from the source blockchain, enabling hot data migration between the source and target blockchains via replication. This allows for smooth and efficient hot migration of blockchain systems such as consortium blockchains.
