Decentralization: Blockchain technology relies on a distributed network of computers to store and process data, which eliminates the need for a central authority or intermediary.↵↵2. Immutability: Once data is recorded on the blockchain, it cannot be altered or deleted. This is because each block in the chain contains a hash of the previous block, making it impossible to change a previous block without altering the hash of all subsequent blocks.↵↵3. Transparency: The blockchain is a public ledger that allows anyone to view the transactions recorded in it. This promotes transparency and accountability in transactions.↵↵4. Security: Blockchain uses cryptographic algorithms to secure the network and protect against unauthorized access and tampering.↵↵5. Autonomy: The self-contained nature of the blockchain allows it to operate independently of any central authority, making it a decentralized and autonomous system.","a":"The main features of blockchain include decentralization, distributed data storage, immutability, traceability, high transparency, and strong security. Decentralization means that there is no single central node controlling the entire network, reducing the risk of network  attacks; distributed data storage ensures data security and reliability by jointly maintaining data through multiple nodes; immutability guarantees the authenticity and credibility of data; traceability allows each transaction to be traced back to its source; high transparency means that all transaction records are publicly available across the entire network, increasing transaction transparency; and strong security is achieved through the application of cryptographic technology, ensuring the security of user information and assets. In addition, blockchain also has the advantage of low transaction costs."}]}],"pr":"fc5722997ad592251b1aa2b1ecbeb993a6052d008be4b011518a925c737b8129"}
