Transaction reversal is the process of undoing a completed transaction on a blockchain. In most decentralized systems, transactions are immutable once confirmed, making reversals rare and typically occurring only in specific circumstances like network reorganizations or through centralized intervention in certain platforms. This contrasts with traditional finance where chargebacks are common.

News concerning reversals often highlights instances where they were necessary due to errors, exploits, or governance decisions. Observers should monitor the conditions under which reversals are permitted and the potential impact on the immutability principle of blockchain technology.
