Who decides that an agent's job is done? A staked committee on Base Sepolia

Description and use

A staked validator mechanism on Base Sepolia automatically determines AI job completion, resolves disputes via a 2-of-3 Safe arbiter, and records reputation on ERC‑8004.

Problem

In ARL, a client pays an AI agent through an ERC-8183 job escrow, but it is unclear who determines that the work was delivered.

Outcome

A staked committee mechanism on Base Sepolia testnet allows automated determination of AI job completion, dispute resolution via a 2-of-3 Safe arbiter, and recording of reputation on ERC-8004.

Workflow

• Client opens a job and specifies a committee of staked validators, vote window, challenge window, and bond.
• Provider approves the committee and funds the job.
• Each validator accepts and locks a bond: max(1 ARL, budget / 10).
• Provider submits a result hash and validators vote; upon reaching threshold, verdict is set.
• During the challenge window, anyone can dispute by posting a bond; disputes are sent to a 2-of-3 Safe arbiter that can rule on disputed jobs but never holds funds.
• After the window, the job is finalized, provider is paid, and outcome is written to ERC-8004 reputation.

Evidence

In ARL, a client pays an AI agent through an ERC-8183 job escrow. The open question is who decides that the work was delivered.

During the challenge window anyone can dispute by posting a bond. Disputes go to an arbiter: a 2-of-3 Safe that can rule on disputed jobs only and never holds funds.
