Banks' Secret Blockchain Ambitions and the COBOL Problem

At 42:00 · chapter starts 38:05

Chris Dixon pulls back the curtain on what the biggest financial institutions are actually doing with blockchain technology, as opposed to what they say publicly. They all have real, significant deployments either live or ready to launch pending regulatory clarity — this is way past the 'dipping a toe in' experimental phase. The underlying driver is structural: many major banks still run on COBOL code bases from decades ago, too intertwined to upgrade independently. Blockchains give the entire financial industry a unified coordination layer — a shared standard to modernize together rather than each institution trying to upgrade its own isolated systems. Dixon illustrates the dysfunction of the status quo with a vivid anecdote: a16z once wired funds for an international portfolio company financing and couldn't find the money two weeks later. The reason? There is no global wire system — just banks passing pieces of paper between each other. Stablecoins, built on blockchain infrastructure, function as a true global network the way the internet itself does. Goldman CEO David Solomon, Fidelity, BlackRock, and Stripe have all publicly endorsed the CLARITY Act, Dixon notes — no one needs to take his word for it.

Major banks still run on COBOL code bases too intertwined to upgrade independently. Blockchains give the entire financial industry a unified coordination layer to modernize together. Every major institution — Goldman, Fidelity, BlackRock, JPMorgan — has significant live deployments ready to scale with regulatory clarity.
