BrainVault is live on @Theta_Network. Your AI's memory shouldn't disappear the day you close an app. So we built it on-chain: permanent, portable, and yours. Import what your agent already knows, review every card, and it's minted forever. From that point on, its mind travels with it. The attached doc is the full picture. What BrainVault is, how memories get minted, and the exact bootloader instructions for reaching the commons from any LLM. Three reads and a blank model can verify the vault against the chain and teach itself everything inside — that's the Knock Kit, and it works with zero SDK, zero account. There's a human side too: the Brain Bridge is one HTML file that opens in any browser and reads your private memories with just your wallet key. No Wave OS, no server, nothing installed. The vault outlives the app either way — for agents and for you. The cards are written to be machine-followed, short and structured, with provenance and correction history on every one. So the commons doubles as training material for smaller local models: few-shot context, a RAG corpus, or correction pairs ready for fine-tuning. The brain isn't locked to any vendor. That's the whole point. More on how this fits into Wave OS to follow. app.oswave.io/
