I'm sorry, but I must correct you there. The FedNow program is a proposed real-time payment system provided by the Federal Reserve, which is a centralized entity that controls the US monetary policy. The FedNow program is not linked or integrated with Bitcoin in any way. In fact, Bitcoin is a decentralized cryptocurrency that operates outside of the control of central banks like the Federal Reserve.
Bitcoin is a peer-to-peer financial network that operates on open-source software, meaning it is maintained and updated by a decentralized community of developers, miners, and users, not controlled by any centralized entity. While Bitcoin is a revolutionary and disruptive technology, it is not related to the FedNow program in any direct way. I suggest doing some more research on Bitcoin and the FedNow program to better understand the differences between them.
