Transaction sequencing fairness is the principle that transactions submitted to a blockchain network are processed and ordered in a manner that prevents any single participant from gaining an unfair advantage. This aims to mitigate issues like front-running, where a validator or miner exploits knowledge of pending transactions. Ensuring fairness promotes equitable access and reduces opportunities for predatory trading practices. It is a critical aspect of network integrity.
