# Micro-Quest Market

**Part of:** Extropy Engine v3.1
**Status:** Adopted (governance-revisable)

## Concept

A micro-quest is a small, signed commitment with:
- a **verifiable completion condition**,
- a **reputation-staked sponsor**,
- a **scope context** (which reputation vector applies),
- an **expiry**.

## Loop

```
propose → accept → attest → settle → reputation update → next quest discovery
```

1. **Propose.** Sponsor's PAI publishes a signed quest entry to the DHT, staking reputation in the quest's context.
2. **Accept.** Solver's PAI handshakes the sponsor; capability tokens are exchanged.
3. **Attest.** One or more independent attestors verify completion and sign attestations.
4. **Settle.** XP is updated in each party's PSLL; reputation is released or slashed accordingly.
5. **Discover.** Next quests are surfaced to the solver weighted by reputation fit and context history.

## Worked example

> Alice's PAI posts: "verify source X claims Y" with 5 rep staked in `verification`. Bob's PAI accepts, returns signed evidence linking primary sources. Carol's PAI independently attests. Settlement: Bob +3 XP `verification`, Alice quest fulfilled, Carol +1 `attestor` XP.

## Anti-sybil

- Quest issuance and attestation cost reputation, not money.
- New DIDs start with low reputation; cannot post or attest meaningfully until they earn it through low-stakes participation.

## Failure modes

- **Sponsor abandonment** → stake decays to attestors after expiry.
- **Collusive attestation** → challenged via dispute quests; if upheld, colluders are slashed in the relevant context.
- **Spam quests** → visibility weighted by sponsor reputation; low-rep quests are not surfaced.
