Definition ∞ Decentralized Finality refers to the irreversible confirmation of transactions within a blockchain network, achieved without reliance on a single central authority or a small, trusted group. This property ensures that once a transaction is recorded and confirmed by a distributed consensus mechanism, it cannot be altered or reverted. It is a fundamental characteristic of secure and censorship-resistant digital ledgers.
Context ∞ The pursuit of robust Decentralized Finality is a primary objective in blockchain protocol design, particularly for networks aiming for high security and resistance to attacks. Discussions often involve the trade-offs between achieving fast finality and maintaining a high degree of decentralization. Advancements in consensus algorithms continue to seek optimal solutions for this critical network property.
