Stratum V2 and mining profitability, AI Agents, and ₿uilder expands!

— Builder meetup expansion: A new monthly meetup called ₿uilder is launching in San Francisco and Miami focused on design, product, and applications rather than technical depth like BitDevs; it aims to attract Silicon Valley builders and executives curious about Bitcoin.

— Vibe coding as the frontier: Andrej Karpathy's talk framed AI as "software 3.0"; the hosts challenge the community to make open protocols (Bitcoin, Lightning, Nostr) the easiest stack to vibe code with, removing DevOps friction.

— Stratum V2 profitability gains: A new study demonstrates that Stratum V2 can improve mining profitability by 7% through better latency and security; allowing miners to select their own block templates (Job Declaration) boosts decentralization and resists censorship.

— Mining pool centralization risk: Three pools control 80–90% of hash rate; Ant Pool alone represents ~40%; Stratum V2 with job declaration distributes transaction selection to individual miners, reducing regulatory chokepoints.

— Authentication and payments as DevOps bottlenecks: Karpathy identified OAuth and payment integration as major friction points in vibe coding; open protocols like Nostr for auth and Lightning/Spark for payments could simplify app development.

— Startup economics for Stratum V2 adoption: Running a Stratum V2 pool or miner requires Bitcoin Core, a proxy (can run on Raspberry Pi), and native ASIC firmware; new pool operators face challenges in recruiting miners and managing payout mechanisms (FPPS vs. PPLNS).

— For miners: Test Stratum V2 with Demand pool or other emerging providers; even without job declaration, the wire protocol alone improves share acceptance and latency, directly boosting margins by 1–2% per profitability data.

— For builders and founders: Use the ₿uilder meetup (first session next Thursday at Presidio Bitcoin, then monthly) to showcase working demos and get feedback; prioritize vibe-coding prototypes over UX mocks to stand out; consider publishing a GitHub proposal first if seeking discussion.

— For protocol developers: Focus on reducing DevOps friction—native Stratum V2 firmware for ASICs, turnkey pool solutions, and zero-knowledge proofs for transaction privacy (StarkWare's recent demo) are high-impact; Stratum V2 adoption unlocks both efficiency gains and decentralization.
