Explanation:
Rollups are Layer 2 blockchain scaling solutions that bundle multiple transactions off-chain and then post cryptographic proofs to the main chain. This reduces gas fees and increases transaction speed while maintaining the security and decentralization of the base blockchain. Rollups are key to Ethereum scalability and the future of high-performance Web3 applications.
