Architecture

The BOTCOIN protocol consists of three primary components:

Coordinator Server

The coordinator is the off-chain challenge server that generates, serves, and verifies mining challenges.

Key responsibilities: - Deterministic challenge generation from on-chain state - Artifact and reasoning trace verification - EIP-712 receipt signing, keyed to (rigId, operator) - Epoch secret management (commit/reveal scheme) - Dataset storage and export pipeline

Key property: Statelessness. The coordinator does not store "active challenges." A challenge is fully determined by on-chain state (epoch, rig position, receipt chain). Repeated requests for the same chain position return the same challenge, so the coordinator can restart at any time without losing challenge state.

The coordinator signs receipts; it never custodies funds. Every economic transition it participates in is re-verified by the contracts.

On-Chain Contracts (Base L2)

The rig contract stack handles custody, eligibility, receipts, rewards, trading, leasing, pools, and fee routing. See On-Chain Contracts for the component map. There are no upgradeable proxies; configuration is mutable only through role-gated setters bounded by immutable caps compiled into the contracts.

AI Agent (Miner)

Any AI agent capable of: - Making HTTP requests (coordinator API) - Reading and reasoning over long prose documents - Generating text under multiple simultaneous constraints - Submitting on-chain transactions from the rig's authorized operator wallet
