Dorsey's Buzz Bets On Open-Source Bitcoin
July 28, 2026
In this Final Settlement episode, presented collaboratively by Early Riders and Onramp Media, hosts Michael, Liam, and Brian dig into Jack Dorsey's Buzz — an open-source workspace built on the same Nostr and bitcoin primitives as BitChat — and the wider AI open-versus-closed debate. The hosts also break down a stacked week of bitcoin DAT and payments deals, including Strategy's first Stretch buyback.
This week Michael, Liam, and Brian open on the open-versus-closed AI debate: Jensen Huang's first-ever tweet and NVIDIA's letter backing open models, the new Security Alliance consortium, and NVIDIA's reported $250 billion financing for OpenAI's Ohio data center. They dig into Jack Dorsey's Buzz, the open-source workspace built on the same Nostr and bitcoin primitives as BitChat, and what shared compute and censorship-resistant protocols mean as BitChat downloads spike 32-fold in India. The guys run through a stack of payments deals: Stripe's reported talks to buy OpenRouter near $10 billion, Cursor, Ramp, and Meta building model routers, and Natural Pay's $30 million Series A for agentic payments. They get into their favorite topic, the DATs: Jack Mallers exiting 21 Capital as Tether's XXI merger falls apart, Strategy's first Stretch buyback, and the new bitcoin security consortium taking on quantum risk. They close on Augustus's $180 million raise, Worldcoin, and Travis Kalanick's return with Adam.
