Topic: Blazebetbr Crash Neymar seeding event (Read 32 times)
Welcome! In preparation for the upcoming launch of our original game Crash Neymar, we're performing this seeding event to ensure fairness and immutable rolls. For this seeding event we are following the same approach as above.
As part of our fairness we generated a chain of 10,000,000 SHA256 hashes where each hash is the hash of the hexadecimal representation of the previous hash. Being the last hash in the chain: eafeab6d840c9c0a7b538eb437678e911dd82b7e74ff5845a3fa54c8ac8a2bc2
We’re gonna be using a BlockHash that hasn’t been mined at the time of this post, we’re expecting to use Bitcoin block 877,056 this to prove we have no influence over the outcome of the game.

Code:
const divisible = (hash, mod) => {
const value = parseInt(hash.slice(0, 13), 16); // Use first 13 hex chars
return value % mod === 0; // Single modulus operation at the end
};
const calculateCrashPointFromHash = function (hash) {
if (divisible(hash, 15)) return 0;
const crashPointBytes = hash.slice(13, 26); // Next 13 hex chars
const h = parseInt(crashPointBytes, 16);
const e = Math.pow(2, 52);
return (Math.floor((100 * e - h) / (e - h)) / 100).toFixed(2);
};
// these will be the 10M pre generated rolls to be used
const hashChain = ['random1', 'random2'];
const gameHash = hashChain.pop();
// It's the hash we're gonna be using of the result of a yet to be mined block on the blockchain # 877,056
const blockHash = '';
const hash = createHmac('sha256', gameHash).update(blockHash).digest('hex');
const crashPoint = calculateCrashPointFromHash(hash);
console.log({ crashPoint });
const value = parseInt(hash.slice(0, 13), 16); // Use first 13 hex chars
return value % mod === 0; // Single modulus operation at the end

const crashPoint = calculateCrashPointFromHash(hash);
console.log({ crashPoint });
