Stake Provably Fair Checker and Calculator

Overview

This Stake provably fair calculator recreates the same HMAC-SHA256 byte stream used by the simulator for demo bets, including server seed hash checks, client seed, nonce and translated game events.

Implementation

The message format is clientSeed:nonce:round. Each round returns 32 bytes.

Conversions

Four bytes become one float using b0/256 + b1/256^2 + b2/256^3 + b3/256^4.

Game Events

Dice-style games scale one float. Table games map floats to cumulative payout rows or shuffled deck positions.

Unhashed Server Seed

Paste the revealed server seed after rotating the seed pair. Active server seeds are intentionally not auto-filled here.
