  One of the potential scalability issues with UTXO-based cryptocurrencies is the large size of the UTXO set. As more transactions occur, the UTXO set grows, which can lead to increased storage requirements and slower transaction processing times. This can limit the scalability of the network.

  Another scalability challenge is the lack of efficient pruning mechanisms for UTXO-based cryptocurrencies. Pruning allows for the removal of spent transaction outputs from the UTXO set, reducing its size. Without efficient pruning, the UTXO set can become bloated, negatively impacting the performance of the network.

  In addition to the UTXO set size and pruning challenges, UTXO-based cryptocurrencies may also face scalability issues due to the limited parallelizability of UTXO-based transactions. Since each transaction consumes specific UTXOs, the parallel processing of transactions can be limited, potentially impacting the overall scalability of the network.
