AI is racing to build new data centres while the GPUs we already have sit at 5% utilisation. IOChain turns that idle hardware into a trustable AI inference infrastructure, settled on Solana. Developers publish models, deployers run them, investors hold fractional shares in the models they back. Pay-per-call, on-chain, peer to peer. Ships with a CLI, Tauri desktop, web app, and TS + Python SDKs.
