FLP Impossibility Result

Definition ∞ The FLP Impossibility Result is a foundational theorem in distributed computing. It states that in an asynchronous network, no deterministic consensus protocol can guarantee termination if even a single process crashes. This highlights a fundamental limitation in achieving absolute agreement.
Context ∞ The FLP impossibility result profoundly influences the design of blockchain consensus mechanisms. It necessitates the adoption of probabilistic safety or alternative models to achieve agreement in decentralized systems, a core challenge for protocol developers. This theorem underscores the inherent trade-offs in distributed ledger technology.
