Base is built on Optimism's OP Stack (1). Optimism is a Ethereum Layer 2 network. As an optimistic rollup, it can allow for much cheaper transaction fees. The tradeoff is that while it inherits security from the Ethereum Layer 1 chain, it does have a bigger attack surface since it is dependent on 2 blockchains.
Coinbase will support the Base chain in their exchange, thereby giving it some utility out of the gate.
