## Immutable Ledgers

An immutable ledger is a database that is append-only, meaning that once data is written, it cannot be altered or deleted. This property is fundamental to the security and transparency of blockchain technology.

In financial derivatives, it provides an unchangeable audit trail of every trade, liquidation, and settlement that has ever occurred. This transparency allows for independent verification of the protocol's health and the validity of its operations.

Because the ledger is immutable, mistakes cannot be simply undone; they must be corrected through new transactions, which can lead to complex recovery scenarios. This creates a high-stakes environment where code quality is paramount.

The immutability of the ledger ensures that historical data remains accessible and verifiable, preventing the retroactive manipulation of records. It is the bedrock of trust in a decentralized system, as it removes the ability for participants to rewrite history for their own gain.

While it introduces rigidity, it also provides a level of security and accountability that is impossible in traditional, centralized financial systems.
