Chain Reorganizations

Chain reorganizations occur when a network temporarily splits into two paths, and the consensus mechanism eventually discards one path in favor of the other. This results in transactions that were previously considered confirmed being reverted, which poses a severe risk to financial derivative protocols.

If a protocol relies on a reorged transaction for liquidation or collateral adjustment, it can lead to massive losses or systemic instability. To mitigate this, many platforms require multiple block confirmations before treating a transaction as final.

Understanding the probability and depth of reorgs is essential for risk management in any system dealing with programmable money and derivative contracts.
