## Blockchain Reorganization

A blockchain reorganization occurs when a node in a network accepts a longer or more authoritative chain than the one it previously considered to be the longest. This can result in transactions that were previously confirmed being discarded or reverted.

In the context of derivatives, this poses a severe risk to settlement finality, as it could undo trades that were thought to be settled. Protocols must implement safeguards, such as waiting for a certain number of block confirmations, to mitigate this risk.

Understanding the probability and impact of reorganizations is essential for developers building financial infrastructure on top of blockchains. It is a fundamental challenge in distributed systems design.
