Every Fintech Firm Will Run Its Own Blockchain `in Next Five Years:' Optimism

It’s only a matter of time until every cryptocurrency exchange and fintech firm is running its own blockchain, according to OP Labs, builder of Ethereum overlay protocol Optimism.The logic is straightforward and simple, says OP Labs head of product, Sam McIngvale, pointing to the runaway success of Coinbase’s layer-2 (L2) network Base since its debut in 2023.For a start, Base has accrued an incredible ecosystem of users and developers to back the exchange, McIngvale said. But the biggest no-brainer is how a system like Base, combined with Coinbase’s bitcoin-backed loans, allows dormant crypto assets sitting in custody to be monetized by lending them out, he added source: https://www.coindesk.com/business/2025/06/18/every-fintech-firm-will-run-its-own-blockchain-in-next-five-years-optimism
