Atomic Transaction

Definition ∞ An atomic transaction is a sequence of operations that either completely finishes or completely fails, leaving no partial results. This property ensures data integrity by preventing intermediate states from persisting. In blockchain contexts, it guarantees that multiple steps within a single operation execute as one indivisible unit. Such transactions are fundamental for reliable and consistent system operation.
Context ∞ Atomic transactions are central to cross-chain interoperability and the development of decentralized finance applications. Their integrity ensures that asset transfers between different blockchains occur without risk of loss or inconsistent state. Current efforts focus on scaling these operations to handle high volumes while maintaining their fundamental reliability, which remains a significant technical challenge for wider adoption.
