Prediction markets on Radix that pay the people who list them
Trade YES or NO from your own Radix wallet. Or list a question with a bond, and a share of every taker fee its traders pay is credited to you.

Tahuna runs on the Radix testnet today. Leave your email and we will tell you when it opens on mainnet.
Trade YES or NO from your own wallet
Every market has its own order book on the Radix ledger. Place a limit order at your price, or take the best price the book shows. Your wallet signs each order.
Question markets ask about events in the world, and people like you list them. Price markets ask whether an asset ends a set window up or down; Tahuna opens them on a schedule, and a signed price feed settles each one.

List a question and earn from its trading
Register your account once, then propose a question with a bond, or with none. A curator reads the wording before the market opens.
When the curator approves it, the bond goes to the Tahuna treasury and your share of the fees is fixed for the life of that market. If the curator rejects it, or you withdraw it first, you can take the bond back. The proposal also carries the reward the oracle pays to the answer that holds.
Your share is credited on every trade. Claim it whenever you like, before or after the market settles.

These are today's values. Tahuna's admin can change the largest bond and the share cap, and a market keeps the terms it opened with, while the challenge window is set in OTER, where its admin or DAO can change it (4 hours today).
How a question settles
When the question can be answered, someone proposes the answer and backs it with a bond. If nobody disputes it within the challenge window, the answer stands and the market settles.
A dispute takes a bond too, and sends the question to a sealed vote of OTER stakers, weighted by stake. The side that loses the vote is slashed. Price markets never go to a vote: the feed settles them.

- Short of that
- The vote runs again; a round with no verdict never voids the market
