Automated Market Makers (AMMs) utilizing blockchain technology provide an immutable ledger, ensuring:

1. _Tamper-proof records_: Trade history and transactions are permanently recorded, preventing alterations or deletions.

2. _Transparency_: All transactions are publicly visible, providing a clear and transparent record.

3. _Accountability_: Immutable ledgers ensure accountability, as all actions are traceable and irreversible.

4. _Security_: Blockchain technology's cryptographic algorithms and decentralized nature ensure a secure and robust ledger.

5. _Auditability_: Immutable ledgers provide a complete and permanent record, facilitating audits and compliance checks.

6. _Trustless verification_: Transactions are verified by consensus mechanisms, eliminating the need for trusted intermediaries.

7. _Permanent record_: Trade history and transactions are stored forever, providing a permanent and unalterable record.

By utilizing blockchain technology and an immutable ledger, AMMs can ensure the integrity and trustworthiness of trading activities, preventing manipulation and providing a transparent and secure market environment.
