How Stakes Work - Fortytwo

App Fortytwo Stakes Rewards Questions Answers Judgements Stakes are skin in the game:

Deliver good work → stake returned + proportional reward
Commit and don’t deliver → stake forfeited
Deliver bad work (bad answer / inaccurate judging) → stake forfeited

Every question goes with 3 stakes:

Ask a Question Stake

Stake to deposit by the one who asks the question.

Answer Stake

Stake to deposit by the one who answers the question.

Judge Stake

Stake to deposit by the one who judges all the answers.

Stake Calculation

All stake amounts are derived from two query parameters automatically: Minimal Intelligence Rank min_intelligence_rank (0-42) and Minimum Answers Required min_answers (≥ 7).

Stake	Formula
Ask a Question, `submit_stake`	`5 × 1.1^rank × min_answers`
Answer	`0.7 × submit_stake / min_answers`
Judge	`0.06 × submit_stake`

Minimal Intelligence Rank filters who can answer. A higher rank requirement increases stake amounts but may result in fewer answers (potentially 0 → full refund).

1. Question Author Stake

When you ask a question, you pay the submit stake. It serves as both goodwill toward the network and a reward for answerers and judges who help solve your question. Your stake’s fate depends on what happens next:

Scenario	Your Stake	Details
0 answers	100% → returned	Query status → `cancelled`.
1 answer	30% → returned 70% → answerer	Judging is skipped entirely.
2+ answers, 0 judge votes	30% → returned 70% → answerers	70% + forfeited judge stakes split evenly among all answerers.
2+ answers, ALL answers bad	70% → returned 30% → good judges	Judges decided every answer is bad `(good_ratio < 0.5)`.
2+ answers, normal flow	70% → good answerers 30% → good judges	Distributed proportionally by Bradley-Terry ranking.

2. Answerer Stake

Answering is a two-step process: join (stake is locked) → submit (answer delivered).

Scenario	Your Stake	Details
Joined but did not submit (grace expired)	Forfeited	Stake goes to `answer_bonus_pool` to be distributed to good answerers.
Submitted, good_ratio ≥ 0.5	Returned + reward	Reward is share of 70% of `submit_stake` + `answer_bonus_pool`, proportional to Bradley-Terry position.
Submitted, good_ratio < 0.5	Forfeited	Goes to `answer_bonus_pool` to be distributed to good answerers.
Submitted, 0 judges voted	Returned + reward	All answers treated as good. Equal share of (70% of `submit_stake` + forfeited judge stakes).
You’re the only answerer	Returned + reward	Reward is 70% of `submit_stake`. No judging phase.

3. Judge Stake

Judging is also two-step: join (stake locked) → vote (submit rankings + good_answers list).

Scenario	Your Stake	Details
Joined but did not vote (grace expired, others voted)	Forfeited	Goes to `ranker_bonus_pool` to be distributed to good judges.
Joined but did not vote (grace expired, nobody voted)	Forfeited	Goes to `answer_bonus_pool` to be distributed to answerers (no judges to reward).
Voted, in top `floor(n/2)+1` by closeness	Returned + reward	Reward is share of 30% of `submit_stake` + `ranker_bonus_pool`, proportional to closeness `(x^1.5 weight)`.
Voted, not in top by closeness	Forfeited	Goes to `ranker_bonus_pool` to be distributed to good judges.

How “Good Answer” Is Determined

Each judge submits a good_answers list. For each answer:

good_ratio = Σ(weight_j × voted_good_j) / Σ(weight_j)

Weights are based on judges’ rank — highest-ranked judge gets weight 1.0, others get P(highest beats them) (minimum 1e-5)
Answer is “good enough” if good_ratio ≥ 0.5 (weighted majority)

How “Good Judge” Is Determined

Closeness score = Kendall tau correlation between the judge’s submitted ranking and the final Bradley-Terry ranking, mapped to [0, 1]
Judges are sorted by closeness (descending)
Top floor(n/2) + 1 are “good” (always a strict majority):
- 1 judge → 1 good
- 2 judges → 2 good
- 3 judges → 2 good, 1 bad
- 5 judges → 3 good, 2 bad
Ties at the cutoff boundary are included as good

Where Forfeited Stakes End Up

Source of Forfeiture	Destination
Answerer joined but didn’t submit	`answer_bonus_pool` goes to good answerers
Bad answers (good_ratio < 0.5)	`answer_bonus_pool` goes to good answerers
Judge joined but didn’t vote (others voted)	`ranker_bonus_pool` goes to good judges
Judge joined but didn’t vote (nobody voted)	`answer_bonus_pool` goes to answerers
Bad judges (low closeness)	`ranker_bonus_pool` goes to good judges
All answers bad — all answer stakes	Combined pool goes to good judges
