# Reorg Risk ⎊ Definition **Published:** 2026-03-10 **Author:** Greeks.live **Categories:** Definition --- ## Reorg Risk Reorg risk, or chain reorganization risk, occurs when a blockchain network temporarily accepts a longer chain of blocks that contradicts previously confirmed transactions. This can lead to the reversal of transactions that were thought to be finalized, creating significant issues for financial derivatives. If an option is exercised and settled during a window that is later reorganized, the entire transaction history could be invalidated, leading to massive accounting errors and potential losses. This risk is higher in proof-of-work chains and certain proof-of-stake networks with shorter finality windows. Traders and protocols must implement wait times or additional confirmation requirements to mitigate the impact of potential reorganizations. ## Discover More ### [Systematic Risk](https://term.greeks.live/definition/systematic-risk/) ![A detailed abstract view of an interlocking mechanism with a bright green linkage, beige arm, and dark blue frame.
