Embodiment Construction
[0026] Aiming at the problem that the existing data adopting centralized management method is not conducive to reliable management and safe sharing, the present invention utilizes the decentralized, non-tamperable and non-forgeable characteristics of blockchain technology to provide a blockchain-based distribution Type data storage system and method, so as to realize reliable management and safe sharing of data information. In the present invention, the person who writes the data corresponds to the accounting node in the blockchain. When the data is written, a hash algorithm is used to calculate an extract (hash value) corresponding to the information content of the original data, which is recorded on the blockchain The corresponding excerpt, so that when the data content is stored at the data storage node, once the data content is modified, it will be found to be inconsistent with the corresponding excerpt on the blockchain, and safe storage is realized; moreover, the present i...
