## Transaction Reversibility

Transaction reversibility refers to the technical ability to undo or invalidate a transaction that has already been recorded on a ledger. In the context of public blockchains, true reversibility is typically impossible by design, as the ledger is meant to be immutable.

However, chain reorganizations or protocol-level interventions can simulate reversibility, which is a major source of systemic risk. For derivatives contracts, this creates a vulnerability where a contract's outcome could be retroactively altered by an external event like a chain split.

Developers must build smart contracts to be resilient against these scenarios, often by incorporating state-check mechanisms. Understanding the limits of reversibility is crucial for legal and regulatory compliance in digital asset markets.

It defines the boundary between decentralized freedom and financial accountability.
