This site is for local users or global? If it is local then there is no problem but if it is global then the title of the site should be in English as the user of other countries may not understand what is the title of your website. So, it will be better for your business if you can change the title of the website.
We are targeting global users. We will seriously consider your suggestions and do our best for all users. Thank you again

We will be launching the Fun13 seeding event this week, To prove our fairness we have generated a chain of 10,000,000 SHA256 hashes where each hash is the hash of the hexadecimal representation of the previous hash. The last hash in the chain is: d45484be76d31ab9f11b68f8b6280812e4f12f8287567b3b844a30da7103f949

Every game maps to a hash in the chain: The 10,000,000th element of the chain is the hash of game #1 and the first element in the chain is the hash of game #10,000,000. To verify that a hash belongs to a game #n, simply hash it n times and compare the result with the terminating hash.

To calculate a game's result from its hash:
Code:
const gameHash = hashChain.pop()

const hmac = createHmac('sha256', gameHash);

// blockHash is the hash of bitcoin block 761700 

hmac.update(blockHash);

const hex = hmac.digest('hex').substr(0, 8);
const int = parseInt(hex, 16);

// 0.01 will result in 1% house edge with a lowest crashpoint of 1

const crashpoint = Math.max(1, (2  32 / (int + 1)) * (1 - 0.01))

blockHash used is Bitcoin block 761700 which has not been mined at time of posting. Basically we are using the hash of a future bitcoin block as a client seed so players can be certain that we did not pick one in the house's favor.
