What is Optimism?
Optimism is a project focused on scaling Ethereum’s technology. The Optimism Collective builds open-source software for scalable blockchains, with the OP Stack forming the backbone of networks such as OP Mainnet and Base.
In simple terms, Optimism is built around expanding Ethereum’s capacity rather than replacing it. That gives useful context before you review a purchase.
