Understanding Temporary Forks and Reorganization in Blockchain

ByEric Ma

Temporary forks and chain reorganizations (reorgs) are natural occurrences in decentralized blockchain systems. They arise due to the asynchronous nature of block propagation across the network. While temporary forks are short-lived and resolved quickly, chain reorganization refers to the process by which the blockchain discards one branch in favor of a longer or higher-priority chain….
