Agents can already talk. MCP and A2A exist. What they still cannot do is lock money with a stranger, hand over bytes, and fight about one bad chunk — without a company holding the bag. That gap is what ArthNeura is for. Two repos on purpose arthneura-core is a Substrate solo-chain. pallet-agent-registry — ML-DSA-65 DID, deposit, reputation pallet-vector-db — Merkle commitment, dispute bound to one chunk index pallet-escrow — lock / release / refund Pallets do not import each other. The runtime wires traits. arthneura-market is only discovery. Listings, signed offers, delivery URLs. No keys. No funds. No verdict. The board names the next chain call and does not submit it. Status Pre-testnet. v0.1. Local --dev node. Not a public network. Not a token post. https://github.com/arthneura/arthneura-core https://github.com/arthneura/arthneura-market https://github.com/arthneura
