Embodiment 1

[0025] A data preservation and management method on a blockchain chain, specifically comprising:

[0026] Set up cloud servers that match the nodes in the blockchain system. The number of cloud servers is the same as the number of nodes in the blockchain system. A single node matches a single cloud server, and each cloud server is not connected to each other;

[0027] In the blockchain system, the control blockchain node divides the data uploaded by its terminal into different data fragments, and the data fragments are manageable blocks;

[0028] After the fragmentation is completed, the storage system encrypts each data fragment on the local system. The control of the encryption process is fully controlled by the content ownership of the data fragment, ensuring that anyone other than the content owner cannot view and access the data fragment The data;

[0029] The blockchain system generates a unique hash based on the fragmented data fragments and the encrypted key, that is,...

Embodiment 2

[0037] Set up cloud servers that match the nodes in the blockchain system. The number of cloud servers is the same as the number of nodes in the blockchain system. A single node matches a single cloud server, and each cloud server is not connected to each other;

[0038] In the blockchain system, the control blockchain node divides the data uploaded by its terminal into different data fragments, and the data fragments are manageable blocks;

The control of the encryption process is fully controlled by the content ownership of the data fragment, ensuring that anyone other than the content owner cannot view and access the data fragment The data;

[0040] The blockchain system generates a unique hash based on the fragmented data fragments and the encrypted key, that is, a fixed-length encrypted output string, and the storage system copies the encrypted data fragments,...

Abstract

The invention discloses a data storage management method on a blockchain, and specifically relates to the technical field of block chains, and specifically comprises the steps that cloud servers matched with nodes in a block chain system are arranged, the number of the cloud servers is the same as that of the nodes in the block chain system, a single node is matched with a single cloud server, andthe cloud servers are not communicated with one another; in the blockchain system, a blockchain node is controlled to divide data uploaded by a terminal of the blockchain node into different data segments, and the data segments are manageable blocks; and after fragmentation is completed, the storage system encrypts each data fragment on the local system, and the control in the encryption processis controlled in the whole process of the content ownership of the data fragment, so that any person unexpected by a content owner cannot check and access the data in the data fragment. According to the method, different data management operations are performed through different verification modes and verification sequences, so that the security of data storage and management on the blockchain canbe improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, and more specifically, the present invention relates to a data storage management method on the block chain chain. Background technique [0002] Blockchain technology (also known as distributed ledger technology) is a decentralized distributed database technology, which has many characteristics such as decentralization, openness and transparency, non-tamperable, and trustworthy, and is applicable to many In application scenarios with high demand for data reliability. [0003] The transaction in the block data is generated by the user of the blockchain. The user sends the transaction to the blockchain node, and the blockchain node packs multiple transactions into the block, and the block will be broadcast and shared on the blockchain network. Consensus, after the blockchain network reaches a consensus on the block, it agrees with the transactions in the block, and saves the execution...
