Grade every market caller before kickoff. Sized with real edge.
Anyone can claim a winning streak after the final whistle. Tally seals every call on Sui mainnet before the start, anchors it into Walrus Memory, and holds every voice to mathematical proof.
The scoreboard
Every caller, scored on the events that already happened.
Backing heavy favourites at 80 cents looks like an 80% win rate while bleeding money every week. Tally grades closing line value and net profit per dollar, call after call, so you see exactly who beats the price.
The kickoff edge
Markets close. The cryptographic seal doesn't.
Every prediction commits a SHA-256 digest to Sui mainnet before the market locks. Tatum gRPC confirms the block checkpoint before kickoff, locking the time and price in stone.
When the market settles, Tally pulls the kickoff line. Callers who consistently beat the closing line print real mathematical profit. Those who don't get benched.
The size
A great call, sized for mathematical edge.
A voice with edge shouldn't bet the house, and a voice without edge shouldn't bet a cent. Tally runs half-Kelly sizing on every earned caller, capped at 2% of bankroll, so you harvest the edge without blowing up.
Size a callBuilt for verification
Ask anything. Inspect every receipt on chain.
Every call and grade archives into Walrus Memory as decentralized blobs. Anyone can query a voice's history using natural language, or verify the exact SHA-256 seal on Sui through Tatum gRPC.
Over 947 decentralized memories across 31 namespaces sit on Walrus right now. No deleted tweets, no edited spreadsheets, no post-game excuses. Just unalterable cryptographic truth.
