Definition ∞ An eUTXO smart contract is a programmable transaction model built upon the Extended Unspent Transaction Output architecture, notably used by Cardano. Unlike account-based models, eUTXO contracts maintain a clearer separation of transaction components, enabling greater parallelism and predictability in execution. This design permits more secure and auditable smart contract logic by preventing certain types of concurrency issues found in other models. It offers a distinct approach to decentralized application development.
Context ∞ The discussion around eUTXO smart contracts frequently highlights their potential for enhanced security and scalability compared to account-based systems. Challenges involve the steeper learning curve for developers accustomed to other models and the need for new programming paradigms. A key future development will be the increasing adoption and tooling support for eUTXO-based platforms, demonstrating their practical advantages in building robust decentralized applications.
