## Chain Re-Org Risks

Chain re-org risks occur when a blockchain network experiences a temporary fork, leading to a situation where a previously confirmed block is discarded in favor of a new, longer chain. This can cause significant issues for financial protocols, as transactions that were thought to be settled might suddenly disappear or be replaced.

In the context of derivatives, a re-org could lead to incorrect margin calls, double-spending of collateral, or the execution of trades based on stale price data. Protocols mitigate this risk by requiring a certain number of confirmations before considering a transaction final, effectively creating a buffer against short-term chain instability.

However, this introduces latency, which is a tradeoff for reliability. Assessing re-org risk is a critical part of building secure financial infrastructure on top of public blockchains, as the cost of a failure is often the loss of user capital.
