## Immutable Ledger History

An immutable ledger history refers to the permanent and unalterable record of all transactions that have occurred on a blockchain network. This property is foundational to financial derivatives, as it provides a verifiable audit trail that is accessible to all participants without relying on a central clearinghouse.

Because the history cannot be deleted or modified, it ensures transparency in trade execution, collateral movements, and liquidation events. This record serves as the source of truth for market participants to verify their positions and the overall health of the protocol.

The inability to alter past data is essential for regulatory compliance and building trust in decentralized finance.
