  Optimistic rollups have the advantage of being more scalable and cost-effective compared to zk rollups. However, one potential drawback is that they rely on fraud proofs, which require users to monitor the blockchain for any fraudulent activity. This can be time-consuming and may introduce delays in transaction finality. Additionally, optimistic rollups are more vulnerable to certain types of attacks, such as long-range attacks and censorship attacks. These drawbacks should be carefully considered when choosing between optimistic rollups and zk rollups for digital currency transactions.

  When it comes to digital currencies, optimistic rollups offer improved scalability and cost-efficiency compared to zk rollups. However, one potential drawback is the need for fraud proofs, which can introduce complexities and potential security risks. Users have to actively monitor the blockchain for any fraudulent activities, which can be a hassle. Moreover, optimistic rollups are more susceptible to long-range attacks and censorship attacks, which can undermine the security of the system. It's important to weigh these drawbacks against the benefits before deciding on the most suitable rollup solution for digital currency transactions.

  From a third-party perspective, it's worth noting that while optimistic rollups provide scalability and cost advantages over zk rollups, they do come with certain drawbacks. One of the main concerns is the reliance on fraud proofs, which can introduce additional complexities and potential security risks. Users need to actively monitor the blockchain for any fraudulent activities, which can be time-consuming and may impact transaction finality. Furthermore, optimistic rollups are more vulnerable to long-range attacks and censorship attacks, which can compromise the integrity of the system. These drawbacks should be carefully evaluated when considering the use of optimistic rollups in the context of digital currencies.
