What Is the Advantage of UTXO’s Inherent Parallelism for Transaction Processing?
The UTXO model allows for a high degree of transaction parallelism because the validity of a new transaction depends only on the availability of its specific input UTXOs. Transactions that spend different, unrelated UTXOs can be processed and validated simultaneously without concern for race conditions or conflicting state changes.
This is a significant advantage over the Account/Balance model, which requires more complex sequential processing to manage a single, global state.
