Pinaivu is private, verifiable AI for healthcare and medical R&D, built on Arbitrum. Independent GPU operators compete in a real-time auction to serve each prompt, prompts are encrypted end-to-end so no one not even the operator can read patient or research data, and every response produces a cryptographically signed, on-chain-auditable receipt. Payments settle trustlessly on Arbitrum and records are archived to IPFS confidential and provable AI, delivered via a chat app and an enterprise API.
Pinaivu is a decentralised network for private, verifiable AI inference, built for healthcare and medical R&D on Arbitrum. Independent GPU operators compete in a real-time auction to serve each prompt; every response is cryptographically signed and produces an on-chain-auditable receipt; and prompts are encrypted end-to-end so neither the operator nor the network can read patient or research data. Payments settle trustlessly on Arbitrum against the signed receipt, and encrypted sessions plus the full receipt history are archived to IPFS. The result is confidential and provable AI the compliance-grade inference that centralised providers structurally cannot offer regulated healthcare buyers delivered through a ChatGPT-style app and an OpenAI-style enterprise API.
We took Pinaivu from a single-chain prototype to a full end-to-end product on Arbitrum, running the complete pipeline live: passkey (ERC-4337) sign-in → sealed-bid GPU auction over libp2p → encrypted inference on independent nodes → Ed25519 proof-of-inference → signed routing receipt → on-chain settlement on Arbitrum Sepolia → IPFS archival → public explorer. We deployed the Solidity contract suite (EnclaveRegistry, SettlementVault) with an Arbitrum Stylus Ed25519 verifier, wired a real GPU-node marketplace (multi-node auction with price/latency/reputation bidding), added IPFS-backed encrypted session memory, and shipped an OpenAI-compatible API gateway + developer dashboard for enterprise integration.
