Check a round’s calculation

Enter the revealed round data and the hash saved before play. The calculation runs in your browser without sending these values to Blinko. It does not verify every pass, the winner or the payment.

Which kind of round?

Choose the scheme that matches the fields in your round’s proof. The two schemes use different inputs and cannot be substituted for one another.

Hash-chain roundOne client seed and a nonce; used by Practice and legacy rounds PvP duelTwo client seeds and match identifiers; TEST or USDT

Round values

serverSeed · hex, revealed after the round clientSeed nonce prevHash / commit · published before the round B · dimensionless value: heat ÷ 100, optional

serverSeed · hex, 64 characters matchId roundId generation roundNonce hostClientSeed · hex guestClientSeed · hex commit · published before the round thresholdCent · arena heat in degrees, optional initialHolder · host or guest, optional

Where to find these values

After a round, open its check from the result screen and expand the technical details. One client seed and a nonce identify the hash-chain scheme; two client seeds and match identifiers identify PvP. Practice has its own local calculation — it is not a proof of a cash duel. To check independently of this page, use the published algorithm with your own tools.
