Account Identification: Each  account in the blockchain network has a unique identifier, usually a pair of keys consisting of a private key and a public key. The public key is used to generate an address, which is the unique identifier for a user on the blockchain. Users can sign transactions with their private keys to prove the validity of the transactions.\\n\\n2. Account Name: Some blockchain systems also provide users with account names for easier memory and recognition. The name is usually associated with the user's public key. Users can query their account name and address in a blockchain browser."}]}],"pr":"be49357f0b503b1bd16989a847e88f930dfd88b86094444f5b6dc63f9cbc8027"}
