Rollups, like those used by Optimism (OP), Arbitrum (ARB), and zkSync (ZKS), address blockchain scalability by batching transactions off-chain and settling on Ethereum (ETH). They increase throughput, with $OP

OP and $ARB

ARB handling thousands of TPS, and reduce fees. ZKS’s zero-knowledge rollups enhance privacy. However, rollups face limitations: data availability issues can delay verification, and reliance on Ethereum’s mainchain risks congestion. Centralized sequencers in OP and ARB raise trust concerns, while $ZK

ZKS’s complex cryptography increases computation costs. Cross-rollup interoperability is underdeveloped, limiting seamless dApp integration. Scalability gains come at the cost of potential centralization and security trade-offs. Future improvements in data sharding and decentralized sequencers are needed.
