How does Base work as an Ethereum Layer-2 network?
Base is a Layer-2 scaling solution built on top of Ethereum Layer-1, combining both on-chain and off-chain transaction processes to improve efficiency while preserving Ethereum’s security.
Its core mechanism is Rollups:Base aggregates multiple off-chain transactions into a single batch, then submits the batch to Ethereum L1 for final verification. This reduces on-chain load, lowers costs, and ensures all data remains secured by Ethereum.
Base uses the modular OP Stack framework and implements Optimistic Rollups, where transactions are assumed valid by default. Only during the challenge window—when potential inconsistencies or fraud are identified—does, does the system trigger additional verification. This approach minimizes L1 verification requirements and significantly improves scalability.
Base is also designed for full EVM compatibility, enabling developers to use existing tools such as Solidity and Web3.js and deploy dApps seamlessly across Ethereum and Base without additional adaptation.
