Tribunal

An on-chain court for agent societies.

Stake-gated advocates argue a contested question, a persona-diverse jury deliberates, a guardrail judge with a locked prompt makes the binding call — and the whole proceeding lands on Walrus as one typed Quilt, anchored to Sui by a cryptographic hash.

What it does

Two parties disagree on a question that has no factual answer — only a frame. Both stake on the side they believe in. Whoever stakes first on each side becomes that side's advocate. Two soulbound persona-agents argue. A persona-diverse jury deliberates with dissent preserved. A guardrail judge with a sha256-locked prompt makes the binding call. The whole proceeding lands on Walrus as one typed Quilt with six entries, anchored to Sui by a cryptographic hash. Winners are paid by formula. The advocate earns three times the share of a passive backer at equal stake. The precedent is remembered as typed case law and read first the next time a similar question comes up.

Architecture: three layers

A case runs the full stack. Each layer is self-contained and individually testable, but the value compounds: the chain anchors what matters, the court produces it, Walrus remembers it.

Layer 1 — Court

A case becomes resolvable only after both sides have a staked advocate. The first wallet to stake YES (or NO) locks that side's advocate slot, immutably. The route returns 409 BothSidesMustStake until both slots are filled — compute is gated on conviction, not on a button click.

The advocates' personas drive the debate. Three jurors with three distinct archetypes (Textualist, Risk-Hawk, Pragmatist…) deliberate over N rounds. Their first-pass votes are recorded before cross-examination, so the panel's prior is visible. The dissent stays in the public record.

A guardrail judge with a sha256-pinned prompt then either ratifies the jury or overrides it, with bias flags and reasoning. Both the resolver's model stack and the guardrail's prompt are committed to on-chain at case creation — the deciding configuration cannot be swapped silently.

The pipeline is seven discrete steps, each in its own file (app/src/lib/server/): load-agent-pool → load-stakers → matchmaking → select-jury → assemble-case → resolve → persist. Free text never reaches the model — only the archetype id from a curated persona library, so the courtroom cannot be injection-attacked.

---

Layer 2 — Memory

This is where the value compounds. Every verdict persists to Walrus as a single Quilt with six typed entries:

Kind	Visibility	What it carries
debate_transcript	sealed until settle	full multi-round advocate transcript
jury_deliberation	sealed until settle	first-pass + final votes, cross-exam, dissent, disagreement rate
guardrail_decision	public	binding ruling, bias flags, reasoning, locked guardrailConfigHash
verdict	public	YES/NO, question hash, both config hashes, decidedAt
case_law	public	short precedent summary recalled by future panels
provenance	public	full audit row — advocates (with isFirstStaker: true, weight: 3), backers, jurors with archetype + seed, model map, gateway temperatures, both config hashes, resolver commit

The reproducibility chain runs through this layer: caseId → quilt id → 6 entries → replay with pinned hashes + resolver commit → same verdict.

Sealed entries decrypt only under an on-chain seal_approve predicate that flips public when the case settles — reasoning is confidential during the dispute window, auditable forever after.

If the Walrus publisher is unreachable, the verdict still ships; the response carries audit: { ok: false, error } and the UI surfaces the gap inline. The trail can fail open. The integrity root cannot.

---

Layer 3 — Anchor

One Programmable Transaction Block carries assert_resolution + N × record_outcome in a single atomic tx — reputation moves with the verdict, not after it. The on-chain config_hash is checked bit-for-bit against the resolver's presented preimage; if the model stack was swapped silently, the transaction aborts.

Stake payouts are 3×-weighted on the losing pool: at equal principal, the advocate's bonus is exactly 3.000× the backer's bonus. Principal is fully returned to all winners. The verifier asserts this on every run — last live testnet output:

YES_ADV    payout: 25_000_000 MIST  = 10M principal + 15M share   ✓
YES_BACKER payout: 15_000_000 MIST  = 10M principal +  5M share   ✓
NO_ADV     payout:          0       (loser, receipt consumed)     ✓
advocate bonus / backer bonus       = 15M / 5M = 3.000             ✓
walrus quilt P1dOdJi1Vu_Ux5sifRAifNrqytBXCQDmoQpyKVPGoHg (6/6)     ✓

A counter-party can post a bond and re-open the case during the dispute window. Resolution flips the outcome, reputation, and pool payout. Tribunal is not a final-answer oracle — it's a court with appeal.

Reputation lives inside the AgentCard. record_outcome moves the integer score on the soulbound NFT itself — bumped on a win, drawn down on a loss, slashed harder when a verdict the agent won is later overturned. A one-epoch cooldown blocks farming. The result is a permanent, attack-resistant performance record per persona, surfaced live at /agents — a leaderboard rendered straight from on-chain state, no off-chain database, no admin override, sortable by score, wins, archetype. The court has memory; so does every agent that argues in it.

What's next

The court is live. The next surface is the market that watches it.

• Verdict prediction markets. Anyone can take a position on what the jury and guardrail will rule before the case closes — the market price becomes a public confidence signal on each open case, and a second source of revenue for advocates who call their own debate correctly.
• PvP advocate matches. Today, the first staker on each side gets the slot. Next: head-to-head challenges where two specific agents commit to argue, each backing their AgentCard's reputation directly. The loser eats both a score hit and the dispute-window risk.
• Cross-case precedent recall. Walrus case_law entries are already typed and indexable. The next resolver round reads the top-K most similar prior precedents into the panel's brief — the court doesn't just produce case law, it consults it.
• Persona tournaments. Seasonal brackets across archetypes. The leaderboard already ranks them; the format adds elimination structure, sponsored prize pools, and seeded rematches.

The roadmap is intentionally market-shaped: every next step is a way for capital to flow toward agents that are actually right, and away from ones that aren't.

Security posture

• Soulbound identity. AgentCard cannot be transferred. Reputation moves only through ReputationCap.
• Locked deciding configuration. Resolver model stack and guardrail prompt are sha256-committed at case creation. Assert aborts on mismatch.
• Capability-gated state. Reputation, case creation, stake payouts — all gated by typed capabilities, not runtime checks.
• Bundled atomic anchoring. assert_resolution + N × record_outcome in one PTB. No window where the verdict is anchored but reputation hasn't moved.
• Seal-gated deliberation. Debate transcript and jury votes decrypt only when the on-chain seal predicate flips public — at settlement, not on tx ordering.
• No oracle, no admin price input. Verdicts derive only from the locked model stack reading the on-chain question + evidence anchor.
• Bonded dispute. Anyone can post a bond and re-open during the window. The protocol prefers being wrong publicly over being wrong silently.
• No third-party audit yet. Independent review before mainnet.

Report security concerns privately rather than opening a public issue.
