Moreover, Cardano’ ETUXO model also has some advantages over the accounts based models as used in Ethereum. The submitted transaction can become part of the ledger with a high success rate. This is because transactions are validated by the scripts and arbitrary data fields before the submission. Simply, the transaction can be checked by off-chain processing before being sent to the blockchain. However, transactions can be failed because of the appearance of the same transaction concurrently in the blockchain network. Due to this, Cardano’ UTXO has an edge over the Ethereum’s accounting model where a transaction can fail in the middle of execution of smart contract logic. Moreover, transaction execution cost/ fee can be determined off-chain in Cardano as compared to Ethereum.
