  As an expert in the field, I can say that optimistic rollups and zk rollups have a significant impact on the scalability of digital currencies. Optimistic rollups allow for faster and cheaper transactions by batching them together and submitting them as a single transaction to the main blockchain. This reduces the load on the main blockchain and improves scalability. However, there is a challenge period during which any invalid transactions can be disputed, which introduces some latency. On the other hand, zk rollups use zero-knowledge proofs to bundle multiple transactions into a single proof, which is then submitted to the main blockchain. This approach eliminates the challenge period and provides better scalability. However, zk rollups require more complex cryptographic computations, which can increase transaction costs. Overall, both optimistic rollups and zk rollups are important solutions for improving the scalability of digital currencies.
