Base is a Layer 2 blockchain network built on Ethereum by Coinbase. It is designed to enhance the scalability and efficiency of Ethereum by offering faster and cheaper transactions while maintaining security through Ethereum's main chain. Base aims to provide a developer-friendly environment for building decentralized applications (dApps) by leveraging Ethereum’s robust security while addressing its limitations in terms of speed and cost.

The network utilizes optimistic rollups, a scaling solution that processes transactions off-chain and posts only the final state back to the Ethereum mainnet, reducing congestion and gas fees. Since its launch, Base has attracted attention due to its association with Coinbase and its potential to bring more users and developers into the Ethereum ecosystem.
