Alby Hub powers a lot of our own operations - we really do a lot of dog fooding and build products we actually need and use! Read Part 1 and Part 2 to learn what Alby Hub is capable of for bitcoin-based businesses. View quoted note →

Sovereign Brain is a simple blueprint for a local AI second brain that runs on your machine. It holds your projects, TODOs, goals, thoughts, and learnings. It pushes back on your ideas, helps you see things from new angles, and keeps you working on what matters. 2026 is the year of sovereign AI. Local AI is now fast and smart enough to run on a laptop. It won't beat the cloud. But it's the only AI you'll share your personal thoughts with. All local and open source: LLM + Pi Agent + Markdown. For me this is a huge unlock: I wasn't comfortable to share this with Claude or ChatGPT. So I thought, maybe other bitcoiners are also interested and surprised that it actually works.

My first game built entirely with a local LLM: 🐍⏪ Rewind Snake

Qwen 3.6 35B A3B: the first time for me that a local model has felt both smart AND fast enough to actually be usable.  **Win sats!** * 10,000 sats to the highest score on Normal Mode * 10,000 sats to the highest score on Enhanced Mode Play it here: [https://rolznz.github.io/rewind-snake/](https://rolznz.github.io/rewind-snake/) *To be eligible, enter your lightning address in the high score entry. Winner announced Wednesday morning US.* I one-shotted a snake game to see if it could... then kept pushing to see how far it'd go. * 🔥 Wall Breaker mode * ⏪ a "rewind time" mechanic — pay to undo your death * 🏆 online high scores + replays * 📱 mobile support + PWA Making a game was just a test. What I really have been after is self-sovereign AI - building on a mid-tier laptop is now possible. **My setup:** Qwen3.6-35B-A3B-UD-IQ3\_XXS on a single NVIDIA RTX 4060 mobile — 8GB VRAM (A mid-tier laptop graphics card) Using llama.cpp, built from source: ./build/bin/llama-server -m Qwen3.6-35B-A3B-UD-IQ3\_XXS.gguf -ngl 99 -np 1 -fa on -ctk q8\_0 -ctv q8\_0 -c 131072 --host 0.0.0.0 --port 8088 -ncmoe 38 --no-mmap (Any ideas how I can optimize it more? MTP was not successful for me - 15% faster but much higher memory usage) I built the app with PI agent. It's great for local-LLM dev because it doesn't waste context. I also connected PI agent to Alby's builder and payments skills. Now I can build payment apps, and my agent can have budgeted, private access to my wallet. I also built a simple "second brain" — a place to brainstorm and dump ideas without being spied on. Looking forward to more self-sovereign AI experiments!
