Why Is the Immutability of an Options Contract Record Crucial for Financial Derivatives?

The immutability of an options contract record is crucial because derivatives rely on the absolute certainty of the contract's terms, execution, and settlement data. If the terms (e.g. strike price, expiration date) could be retroactively altered, the entire contract would be worthless and non-enforceable.

A blockchain's immutability provides a non-repudiable record for all parties.
