A » Rollups, both Optimistic and ZK, enhance blockchain scalability by processing transactions off-chain, but they face limitations like reliance on complex cryptography, increased latency due to fraud proof periods (Optimistic), and computational intensity (ZK). Additionally, they depend on robust off-chain data availability, require trust in rollup operators, and may encounter interoperability challenges with different layer-1 blockchains, impacting their broader adoption and usability.

A »Rollups, including Optimistic and ZK, have limitations such as data availability issues, potential security risks, and complexity in implementation. They also rely on the underlying blockchain's security and may face scalability limits due to data compression and verification requirements, restricting their capacity to process high transaction volumes.
