Block Reorg

Block

A block reorg, within cryptocurrency contexts, represents a significant alteration to the historical record of a blockchain, specifically involving the replacement of one or more blocks with a newly discovered, longer valid chain. This event fundamentally reshapes the perceived transaction history, potentially invalidating previously confirmed transactions. The probability of a substantial reorg diminishes as the chain grows and computational resources securing it increase, though it remains a theoretical risk, particularly for smaller or less established blockchains.
