Bringing Bitcoin to Every Square Seller in America

Marty sits down with Miles Suter to discuss Block's eight-year journey building Bitcoin infrastructure across Cash App, Square, and BitKey. Miles explains how the company integrated Bitcoin buying and selling into Cash App in 2018, launched Lightning payments, and now brings Bitcoin acceptance to every Square seller in America. They reflect on the lonely early days of Bitcoin adoption from 2013-2019, the importance of open source development through Spiral, and Block's Bitcoin-only strategy. Miles details the philosophy behind building in public, funding projects like BTC Pay Server and LDK, and the recent BitKey security upgrade enabling chain code delegation for enhanced privacy. He shares his vision for revitalizing Cash App Bitcoin and making Bitcoin everyday money.
