Yes, Ethereum uses the UTXO model. The UTXO model is a data structure that is used to keep track of unspent transaction outputs. In the UTXO model, each transaction has a list of inputs and outputs.
The inputs are references to UTXOs that are being spent by the transaction. The outputs are new UTXOs that are created by the transaction.
NOTE: It is important to note that Ethereum does not use the UTXO (Unspent Transaction Output) model. Instead, Ethereum uses an account-based system for tracking account balances and transactions. This means that Ethereum transactions do not have the same structure as Bitcoin transactions and are not compatible with Bitcoin wallets. Therefore, attempting to use a UTXO-based wallet with Ethereum will likely result in errors or unexpected results.
The UTXO model has several advantages over other data structures, such as the account/balance model. First, the UTXO model is more efficient because it only needs to keep track of unspent outputs.
Second, the UTXO model is more flexible because it can support multiple types of transactions, such as token transfers and contract executions. Finally, the UTXO model is more secure because it is harder for attackers to create double-spending attacks.
