However, these transaction data can be imported, exported, and deleted. Import and export refer to the migration of transaction data from one platform or system to another. Deletion refers to the removal of certain transaction data in specific situations, such as involving illegal activities or sensitive information. However, it should be noted that deleting transaction data may affect the decentralization and security of the blockchain. When performing these operations, relevant laws, regulations, and agreements of the blockchain platform should be followed."}]}],"pr":"2164102f9bb7afa2152f8f91353b8bae2dc7e3b7c8eeb9576b219b85c9f6f88c"}
