EUTXO
Also known as: Extended UTXO
Extended UTXO model combining UTXO structure with smart contract capabilities.
EUTXO (Extended UTXO) enhances Bitcoin’s UTXO accounting model by adding support for complex smart contracts, deterministic execution, and script validation. It enables improved scalability, parallelization of transactions, and predictable fee estimation. Pioneered by Cardano, EUTXO supports features like time-locks, multi-asset tokens, and decentralized governance, offering a robust balance between privacy, performance, and programmability.
