It divides the data into different blocks, each of which contains a certain number of data records. Blocks are connected to each other through specific information, forming a timechain arranged in chronological order. This structure uses cryptographic means to ensure the security and immutability of the data. The core  technologies of blockchain storage include distributed data storage, decentralization, encryption algorithms, and consensus mechanisms. In a blockchain network, each node saves complete blockchain data, jointly participating in data verification and maintenance, making data storage more secure and reliable."}]}],"pr":"01d44ff4a9e7b6559aa681ca9610cb67a62cca61e9783f45249c72b5effd6ac3"}
