Decentralization: Blockchain technology operates without a central authority or middleman, which means that transactions are processed directly between participants without the need for a third-party intermediary.↵↵2. Immutability: Once data is recorded on the blockchain, it cannot be altered or deleted. This is because the blockchain is composed of a series of interconnected blocks, each containing a certain amount of data. When a new block is added to the chain, it becomes increasingly difficult to modify or remove previous blocks.↵↵3. Transparency: The blockchain is a public ledger that records all transactions conducted within the network. This means that anyone can view the contents of the blockchain, ensuring transparency and accountability in the system.↵↵4. Security: Blockchain technology employs cryptography to secure the network and protect against unauthorized access and tampering. Each block in the blockchain contains a cryptographic hash of the","a":"The key features of blockchain technology include decentralization, data transparency, difficulty in tampering, high security, and consensus mechanisms. Decentralization means that there is no single central node, thereby reducing the risk of system failures and attacks; data transparency is manifested in the fact that all transaction records are open to all participants, improving transaction transparency; difficulty in tampering is due to each block containing the encrypted hash value of the previous block, so once the data in a block changes, it will affect the hash value of subsequent blocks; high security is attributed to cryptographic principles, ensuring secure storage and transmission of data; and consensus mechanisms are  the way that nodes in the blockchain network reach agreement, such as proof-of-work."}]}],"pr":"6a52bc04c63c0a68f059a554cb4ea1d22400ca8ca1317e122ffeeebf8a4c3a29"}
