Decentralization means that there is no centralized storage and management institution; the data is distributed across multiple nodes in the network, and  each node participates in the verification and maintenance of the data. This distributed characteristic makes the blockchain system more secure and reliable because to tamper with or seize control of the entire database, attackers need to break into most of the nodes in the network simultaneously, which is virtually impossible in practical operations.↵↵In addition, blockchain employs encryption algorithms (such as SHA-256) to ensure the security of the data. Each block contains the hash value of the previous block, forming a chain of blocks, hence the name"}]}],"pr":"3bc158c17ba5952a0a9af4b1abca7f746089c05af57b5ef3cfe46d2a932f9a1d"}
