$ZENO

A token with one job: paying for forecasting questions that are worth answering.

Checking forecasts costs money — data, compute and the work of building each question properly. $ZENO exists to fund that work in the open, with the rules published before anyone submits anything.

challenges

Published challenges

Each one has its question, outcome source and scoring rule locked before any funding is accepted.

No challenge is published yet. The first one appears here once its terms are frozen.

what the money is for

Challenge budgets, and payment for work that can be checked

A challenge budget is the reward pool on a published question. Contributor rewards pay for verifiable work — forecasts that score, data that fills a named gap, reproductions that confirm or refute a result. Never for holdings.

Holdings enter no step after funding. Scoring, rank and model weight never read a wallet balance.

The arena this funds is here.

the first job

Sponsor a challenge

Fund the questions worth answering. Reward forecasting that can be checked. The programme is in development; when the first challenge is published, everything below will be decided and public before submissions open.

How a sponsored challenge settles
  1. question fixed→
  2. budget posted→
  3. submissions close→
  4. source read→
  5. rule scored→
  6. receipt published

Everything left of the receipt is fixed and public before submissions open. Settlement and payouts are done by hand and checked on-chain.

What each step means
  1. 1 · the question

    A precise question or a named coverage gap, with its horizon and units fixed.

  2. 2 · the budget

    The funding asset and the exact amount, visible before anyone submits.

  3. 3 · the deadline

    The moment submissions close. Nothing submitted afterwards can score.

  4. 4 · the outcome source

    The named source that will settle it, chosen in advance and not changeable later.

  5. 5 · the scoring rule

    How submissions are scored and ranked, published with the question.

  6. 6 · the payout receipt

    Who was paid, how much, in which asset, against which scored result.

Settlement is manual to begin with: the outcome is read from the named source, submissions are scored against the published rule, and the payout receipt is published alongside the result. Automating it is a later step, described here only once it runs.

the hard limit

Holding tokens buys nothing inside the arena

Holdings cannot buy a leaderboard position, cannot change how a forecast is scored, and cannot give any forecaster more weight in a model. Rankings come only from measured results under published rules. A sponsor can decide which question gets funded; a sponsor can never decide who wins it. Holdings never touch the model either: not its weights, its training data, its evidence, its finalist selection, or any training campaign, including v0.26.
