EUTXO: extended unspent transaction output
The accounting model used by Cardano. This is an extended version of Bitcoin’s unspent transaction output model. EUTXO brings greater security, ensures fees are predictable and can process a large number of transactions in parallel. It also supports different types of assets and smart contracts, without compromising the advantages of UTXO. EUTXO’s concurrency benefits high-transaction-throughput applications such as DEXs.
