Frequently asked questions
What is SealedSlate?
SealedSlate is a transparent sports-prediction track record. Every prediction is sealed with a SHA-256 hash before kickoff and settled from official final results, so entries cannot be edited after the fact — 904 predictions are on the public ledger.
Does SealedSlate sell picks or claim to beat the market?
No. An honest 1350-game backtest showed a -6.77% value-bet ROI, and we publish that openly. The value here is a tamper-proof, independently verifiable record — not a betting edge.
Is SealedSlate free?
Yes. During the measurement phase every prediction, the full ledger, and the methodology are public and free.
