Ethereum, the world’s second-largest cryptocurrency by market capitalization, does not have a UTXO model. Instead, it has a account-based model.
In a UTXO model, each transaction outputs can only be used as inputs in future transactions. This is similar to how physical cash works – each bill can only be used once.
The UTXO model is more straightforward and is used in Bitcoin.
In an account-based model, there are no outputs or inputs. Each account has a balance and transactions simply modify the balances of the accounts involved.
This model is more flexible and is used in Ethereum.
NOTE: Warning: Ethereum does not use the Unspent Transaction Output (UTXO) system like Bitcoin does. This means that Ethereum transactions do not have the same structure or features as Bitcoin transactions. Furthermore, it is important to note that Ethereum does not use the same type of wallet structure to store funds like Bitcoin does. Therefore, it is important to be aware of the differences between Ethereum and Bitcoin before attempting any transactions with either system.
The main advantage of the account-based model is that it’s more flexible. For example, in the UTXO model, it’s not possible to send a transaction to multiple recipients.
In the account-based model, this is possible because there are no outputs or inputs – each account has a balance and can receive any number of transactions.
The disadvantage of the account-based model is that it’s more complicated and less transparent. In the UTXO model, it’s easy to see which outputs have been spent and which have not.
In the account-based model, all transactions are stored in a single place and it’s not always clear which ones have been processed and which ones have not.
Overall, the account-based model is more flexible but less transparent than the UTXO model. Ethereum uses the account-based model because it offers more flexibility for developers.
