Know who is actually right.
For anyone who makes calls, or follows people who do. Proven records every call before the event, checks it against real prices after, and remembers who was right and how sure they claimed to be. Then it answers two questions with that memory: who should I trust on this? and how confident should I be?

Put your own name on the board. Every step below writes to Sui mainnet and is checked with real prices.
Ask: who should I trust right now?
The same open question, answered twice. On the left, everyone counts the same. On the right, Proven uses what it remembers.

Log your own call, or one from someone you follow. It is saved before the deadline and checked against the real price after it.
Waiting for results
Nothing open.

How Proven decides
No hidden settings. Every number on this page comes from these rules, applied to what is in memory.
Brier score: (confidence − outcome)². Saying 90% and being right costs 0.01. Saying 90% and being wrong costs 0.81. Being honest about doubt is rewarded.
Every source starts as if it had 3 coin-flip calls. One lucky call can't put anyone on top; a long record can.
Trust is how much better than a coin flip (0.25) a source scores, shared out across sources. Worse than a coin flip keeps a small floor, so anyone can earn their way back.
A source saying 80% that is right 60% of the time is read closer to 60%. The more results it has, the more its record outweighs its words.
Proof
Nothing here lives in a private database. The page you are reading was rebuilt from records on Sui mainnet a moment ago.
Memory account —. Receipts open the stored record on Walrus. Records are encrypted, so a receipt proves when a call was written and that it was never changed; Proven decrypts them with its own key to rebuild this page. Strategies are simple published rules that only see prices from before their call.
