Title: Strongman Game Seeding Event - nitro.bet
Post by: nitrobet on January 18, 2021, 09:42:12 AM

Welcome to our seeding event for Strongman launching next week.

We have generated a chain of 10 million SHA256 hashes, starting with a server secret that has been repeatedly fed the output of SHA256 back into itself 10 million times. The SHA256 of the final hash in the chain is: d0d99b3450ab0631ac2ef485f694829182bf410bf59377262db496fbcdb4da81, by publicising it here we are preventing any ability to pick an alternate SHA256 chain.

Strongman game will play through that chain of hashes, in reverse order, and use the hashes to determine the game outcome in a probably fair manner.

Code:

const nBits = 52; // number of most significant bits to use

        // 1. HMAC_SHA256(key=salt, message=seed)
        const hmac = crypto.createHmac("sha256", salt);
        hmac.update(seed);
        seed = hmac.digest("hex");

        // 2. r = 52 most significant bits
        seed = seed.slice(0, nBits/4);
        const r = parseInt(seed, 16);

        // 3. X = r / 2^52
        let X = r / Math.pow(2, nBits); // uniformly distributed in [0; 1)

        // 4. X = 99 / (1-X)
        X = X*100 + 1;

        // 5. return max(trunc(X), 100)
        const result = Math.floor(X);
       return Math.max(1, Math.min(100, result));

Before being used to calculate the corresponding result, each game hash is salted with the lowercase, hexadecimal string representation of the hash of bitcoin block 667000. This block has not been mined yet, proving that we have not deliberately picked a chain that is unfavourable for players.

Excited to show you the Strongman game very soon!

Quoting. And saved to archive.is: https://archive.is/gTffQ

Also confirming that the current best bitcoin block is: 666592 and thus 667000 has not yet been mined.

What is the guarantee of quoted the OP using the same newbie account here from bitcointalk?

I'm also quoting below. But in any case, the topic can also be verified by ninjastic.space here (https://ninjastic.space/post/56124792).
The current block of the Bitcoin blockchain is 666623

Wow, I see this casino or game to be very sophisticated, as it works like solving complex Mathematical problem of the btc mining process.

What I want to know is, what's the chance of one winning in this kind of complex game.?
