116. Decentralizing Pool Payouts: Inside GridPool with Agent P

In this episode, we sit down with Agent P to unpack his open-source project GridPool, a radically simple approach to decentralizing Bitcoin mining payouts. We trace his journey from early concerns about mining centralization during the China ban to reverse‑engineering Ocean’s Datum client to build a compatible, open server—enabling client-side block template construction without relying on a centralized payout custodian. Agent P walks us through GridPool’s on-deck and winners lists, how difficulty-ordered but evenly split payout slots remove the need for a latency-prone share chain, and why this design can serve both medium-size miners seeking lower variance and small “lottery” miners. We also discuss compatibility with Hydrapool, potential Stratum V2 and CKPool integrations, bootstrapping a decentralized node network, and how GridPool preserves censorship resistance by only sharing minimal data necessary for verification. We close with a fascinating detour into vibe coding: Agent P details using AI agents to port open-source firmware onto closed miners—compiling and live-loading Mujina onto an S19 XP via SSH with minimal manual intervention—illustrating how AI lowers the barrier for anyone to contribute to open-source mining tools. If you’re passionate about censorship resistance, decentralized pool payouts, and hands-on experimentation, this is a must-listen. Resources: gridpool.net • Hydropool and P2Pool v2 repos (community forks) • February Forum thread on firmware tips for Antminers • Testnet4 participation for GridPool bootstrapping
