Optimism, Arbitrum, Polygon, Starknet, Scroll and now Base. Last week Coinbase launched its own blockchain network. Named Base, it is an Ethereum layer 2 network created using the Optimism stack.
This launch is not just significant in terms of onboarding more participants to web3 (Coinbase has over 100 million users). It also represents a playbook we may well see other large companies embrace to launch their own public blockchain networks.
