🔒 HASHSCORE Now Provably Fair - Thanks to 
!
TL;DR
HASHSCORE games are now provably fair using cryptographic secrets that change every minute. Players can no longer predict scores before sending transactions, and every game result can be independently verified. This upgrade was inspired by feedback from
What Changed?
The Problem
- Sign a transaction locally
- Calculate the resulting hash score using our public algorithm
- Only broadcast transactions with favorable scores
- Reject unfavorable scores and try again
This defeated the randomness of the game. Props to
The Solution: Provably Fair Gaming
We've implemented a provably fair system inspired by 
How it works:
- Server-side secrets - Our server generates a random 16-character secret every minute
- Salted hash calculation - Your score is calculated from
SHA256(transaction_hash + secret)instead of the raw transaction hash - Unpredictable - Since you don't know the secret when you send your transaction, you can't predict your score
- Transparent - After your game completes, we reveal the secret in your reward memo
- Verifiable - You can independently verify your score was calculated fairly
The Formula:
salted_hash = SHA256(your_transaction_hash + server_secret)
your_score = sum of all hex characters in salted_hash
Instant Verification
Every reward transaction now includes:
- Your secret - The exact secret used for your game
- Verification link - One-click verification at https://hashscore.fun/verify.php
Example memo:
Result: HASHSCORE Default | Win High | Your HASHSCORE: 463 |
Secret: K1jyq5sV3PHZuhSs |
Verify: https://hashscore.fun/verify.php?tx=abc123...&s=K1jyq5sV3PHZuhSs
Click the verify link and you'll see:
- ✅ Your transaction hash
- ✅ The secret used
- ✅ Recalculated score (matches your result)
- ✅ Proof the game was fair
Why This Matters
Before: Trust-Based
You had to trust that our system was fair. There was no way to verify.
After: Cryptographically Verifiable
- Transparent - The exact formula is public
- Unpredictable - Secrets change every minute
- Verifiable - You can prove every game was fair
- Fair - Neither player nor house can manipulate results
This is the same proven system used by other successful blockchain gaming platforms like
Real-Time Results
We've also upgraded the user experience:
Old way: Instant preview showing predicted score (now we know this was wrong!)
New way:
- Transaction sent → Shows "Processing..."
- Polls server every 10 seconds
- When complete → Shows real results:
- Your actual hash score (with secret)
- Win result (High/Low/Average)
- Reward amount
- Secret and verification link
- One-click to verify fairness
Technical Details (For the Nerds 🤓)
Secret Rotation:
- New secret generated every 60 seconds
- Secrets are cryptographically random (16 alphanumeric characters)
- Secret determined by transaction timestamp, not processing time
- Same transaction always uses same secret (deterministic)
Database Storage:
- Every transaction stores which secret was used
- Full audit trail for transparency
- Secrets stored in indexed table for fast verification
Verification Process:
// What you can verify:
$salted_hash = hash('sha256', $your_tx_hash . $revealed_secret);
$your_score = calculate_score($salted_hash);
// Compare with the score we gave you - they match!
