As a decentralized distributed ledger technology, blockchain achieves data security, transparency, and tamper-proof through technical means such as peer-to-peer transmission, consensus mechanisms, and encryption algorithms. In each block, the data record contains the hash value of the previous block, forming a continuously growing chain. This structure makes it difficult to tamper with the data in blockchain because any tampering requires simultaneous modification of all subsequent blocks.↵↵However, blockchain technology does not completely guarantee the authenticity of the original data. Although the data on the  blockchain cannot be tampered with, the source and authenticity of the original data still need to be verified."}]}],"pr":"f703e5f360798d94339800bdcfd6f98b6266a642dffca769975f4e93969de58b"}
