Retroactive Transaction Intolerance

Definition

Retroactive transaction intolerance means a system cannot change past recorded transactions. This refers to a fundamental property of immutable ledgers, such as blockchains, where once a transaction is confirmed and added to the chain, it cannot be altered, reversed, or deleted. This characteristic ensures the integrity and finality of records, preventing double-spending and fostering trust in the system. It is a core tenet of blockchain security, ensuring that historical data remains unchangeable.
