Problems solved by technology

[0006] In order to solve the problems existing in the prior art, the present invention innovatively proposes a location selection method, system, equipment and storage medium for a copy of a block chain large file, which effectively solves the problem that the distributed P2P storage network does not take into account the storage location of a copy of a large file. Unbalanced storage and access delay caused by inappropriateness can reduce the amount of data stored in the blockchain, improve the response time of P2P storage network external services, and avoid the storage explosion of a storage node due to unbalanced storage.

Embodiment 1

[0048] like figure 1 As shown, the present invention provides a block chain large file copy site selection method, which is applied in a P2P storage network, including:

[0049] S1, establishing a blockchain application system, multiple blockchain nodes in the blockchain application system jointly maintain a shared ledger, and the shared ledger records the hash value corresponding to the large file requested by the user to be stored;

[0050] S2, establishing a P2P storage network, where several storage nodes in the P2P storage network provide off-chain storage for the blockchain;

[0051] S3, the block chain node that obtains the accounting right of the shared ledger determines the storage node set for large file backup according to the final cost of the storage nodes in the P2P storage network.

[0052] Among them, such as figure 2 As shown, in step S1, specifically include:

[0053] S11, establish a blockchain application system and deploy multiple blockchain nodes;

...

Embodiment 2

[0084] like Image 6 As shown, the technical solution of the present invention also provides a block chain large file copy site selection system, which is applied to the P2P storage network, including:

[0085] The first establishment module 11 is used to establish a block chain application system. A plurality of block chain nodes in the block chain application system jointly maintain a shared account book, and the hash value corresponding to the large file requested by the user is recorded in the shared account book. ;

[0086] The second establishment module 12 is used to establish a P2P storage network, and several storage nodes in the P2P storage network provide off-chain storage for the block chain;

[0087] The determining module 13 is used to determine the set of storage nodes for large file backup according to the final cost of the storage nodes in the P2P storage network for the block chain nodes to obtain the shared ledger accounting rights.

[0088] The invention ...

Embodiment 3

[0092] like Figure 7 As shown, the technical solution of the present invention also provides a copy addressing device for large blockchain files, including: a memory 21 for storing computer programs; a processor 22 for executing the computer programs to realize the The steps of the method for selecting a location for a copy of a block chain large file.

Abstract

The present invention proposes a location selection method for a block chain large file copy, which is applied to a P2P storage network, including: establishing a block chain application system, and multiple block chain nodes in the block chain application system jointly maintain a shared ledger, The hash value corresponding to the large file requested by the user is recorded in the shared account book; a P2P storage network is established, and several storage nodes in the P2P storage network provide off-chain storage for the blockchain; The block chain node determines the storage node set for large file backup according to the final cost of the storage node in the P2P storage network. The amount of data, improve the response time of P2P storage network external services, and at the same time avoid the problem of a storage node storage explosion caused by unbalanced storage.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a location selection method, system, equipment and storage medium for a copy of a large blockchain file. Background technique [0002] As a decentralized distributed storage ledger, blockchain can provide traceable and secure storage for data on the chain. However, because the traditional blockchain system uses a full-copy storage method to ensure data security, it brings a lot of storage overhead to the nodes. At the same time, as blockchain technology is widely used in medical and government affairs and other fields, there are more and more storage requirements for large files such as electronic medical records and electronic certificates in blockchain, which further intensifies storage and network communication expenses. [0003] To solve this problem, there are two mainstream solutions in the existing technology from the perspective of adopting the "on-chain" ...
