Each block contains a certain amount of data, and when a block is filled up, a new block is created and linked to the previous block, forming a chain-like structure. The core advantage of blockchain technology lies in its decentralized, secure, reliable, transparent, and traceable features, making it widely used in finance, supply chain management, IoT, and other fields. Blockchain technology was initially developed for the Bitcoin payment system but later evolved into an independent technology that is expected to change the future."}]}],"pr":"0b7e309371faa562795ce8f4ed85ea1c23e6b377451bb310dba9148d7a38d8b3"}
