$USDC Distributed ledger: Blockchain uses distributed ledger technology, maintaining records of transactions across multiple nodes, each of which has a complete copy of the ledger. This means that all information about transactions is open to network participants, and anyone can view the transaction history, verify

their authenticity and integrity.

• Timestamp and blockchain: Records of transactions are recorded in chronological order in blocks and linked together in a chain. This structure ensures the consistency and immutability of transactions; once a transaction is recorded in the blockchain, it cannot be changed or deleted, providing a reliable chronological order and transaction history.
