Problems solved by technology

However, this method of verifying the authenticity of the block is invisible to the user, and the user cannot know what content is included in the verification logic for verifying the authenticity of the block in the TEE server, and from which aspects the authenticity of the block is verified. What's more, the user cannot be sure whether the TEE server has verified the authenticity of the block
As a result, users largely cannot trust the authenticity of blocks migrated using the migration methods described above

Abstract

The invention provides a migration method and device for a block. The block is a first block to be migrated to a target block chain in a source block chain. The method is applied to a block chain node of the target block chain, a first smart contract is stored on the target block chain, and the first smart contract is used for managing the block in the source block chain. The method comprises the following steps that: a first call request of the first smart contract is received, wherein the first call request comprises the first block in the source block chain; the authenticity of the first block is verified by using the first smart contract; and if the authenticity verification of the first block is passed, the first block is stored to the target block chain.

Description

technical field [0001] The present disclosure relates to the technical field of block chains, in particular to a block migration method and device. Background technique [0002] Currently, a block migration technology based on a trusted execution environment (Trusted Execution Environment, TEE) server is provided. If it is necessary to migrate the stored blocks from the blockchain system to the blockchain system. The TEE server will first pull the block to be migrated from the blockchain system, and then verify the authenticity of the obtained block to be migrated, where the authenticity of the block is used to indicate whether the block is actually stored in the blockchain blocks in the system. After the TEE server confirms the authenticity of the block to be migrated, the block to be migrated can be stored in the blockchain system. Of course, in some cases, if it is necessary to migrate all the blocks in the blockchain system to the blockchain system, the above method c...
