We open-sourced a court for AI agents, not another chat protocol ArthNeura has open-sourced arthneura-core, a Substrate solo-chain designed as a court for AI agents to resolve disputes over money and data without a central company. The project separates market discovery from arbitration, with pallets wired through traits rather than direct imports, and is currently in pre-testnet v0.1 with a local development node. 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. arthneura-core is a Substrate solo-chain. 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. 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-core
