Problems solved by technology

[0003] In the existing technology, from the perspective of the file storage service provider, the current side chain storage nodes are mixed, which may cause the side chain storage service provider to be unstable, the system lacks maintenance, and the use of off-chain storage service nodes will also be due to the conflict with the storage service provider. The cooperation is terminated, and the original files need to be migrated
From the perspective of the project operator, when the operator changes, its associated file storage service provider may also change
However, there is no relevant technical solution for changing storage service nodes in the prior art

Embodiment Construction

[0037] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0038] Such as Figure 1-2 As shown, in the first embodiment of the present invention, a method for changing the file storage service address associated with the main chain of the blockchain is provided, and the first file storage service node associated with the main chain of the blockchain stores at least one The first electronic file, the first hash value associated with the first electronic file and the first storage address of the first electronic file are recorded on the block chain main chain, and the first storage address is the same as The first file storage service node is matched; the method includes:

[0039] In response to a storage address change request issued by the first file storage service node for the first electronic file; the storage address change request is signed by the first private key of the first file storage service node; the st...

Abstract

The invention discloses a file storage service address changing method of a main chain of an associated block chain. The invention relates to a block chain field, comprising: first, verifying whethera storage service node initiating a storage address change request is a current storage service node of the first electronic file in response to a storage address change request of the first electronic file issued by the first electronic file storage service node; then, in response to the first hash value of the first file being the same as the second hash value of the second storage address, thestorage address of the first electronic file is recorded as the second storage address on the block chain main chain. At the same time, the invention also discloses a file storage service address changing system of a main chain of an associated block chain. The technical proposal for changing the address of the file storage service provided by the invention enables the service node of the large file storage of the block chain to migrate and reduces the file loss rate.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a method and system for changing addresses of file storage services associated with block chain main chains. Background technique [0002] Due to the limited storage capacity of each block of the blockchain, in order to avoid excessive storage burden on the main chain in the blockchain project, when large files are involved, generally only the hash value of the file is stored on the main chain of the blockchain, while Store large files on sidechain storage nodes or traditional non-blockchain storage nodes. [0003] In the existing technology, from the perspective of the file storage service provider, the current side chain storage nodes are mixed, which may cause the side chain storage service provider to be unstable, the system lacks maintenance, and the use of off-chain storage service nodes will also be due to the conflict with the storage service provider. The cooperation...
