Blockchain Reorganization Risk

Blockchain reorganization risk, or reorg risk, is the possibility that a portion of the blockchain is discarded and replaced by a new, longer chain, effectively reversing previously confirmed transactions. This happens when two miners or validators produce blocks simultaneously, creating a temporary fork.

In financial terms, this risk is particularly dangerous for exchanges, as it can lead to the reversal of deposits or trades, potentially causing significant financial loss. Managing this risk involves setting appropriate confirmation thresholds and monitoring the network for signs of instability.

It is a critical aspect of risk management for any platform that settles trades on a public blockchain. Understanding the factors that influence reorg probability is essential for secure operations.
