Crash - Provably Fair

This game uses two seeds:

• Server Seed - provided by us
• Client Seed - the hash for bitcoin block #633568

We take a Server Seed and hash it (SHA256), creating a new Server Seed. Then we take that Server Seed and hash that too. We repeat this process until we have 2 million hashes -- 2 million server seeds. The very first game of crash (Game #1442359) uses the 2 millionth server seed (54924f1e6be74137bd13953c34cbc0c4543a33549d8ffbefb9d4962f19dc7db5), and each game after that works backwards down the list of server seeds. Second game uses the 1,999,999th hash and so on and so forth.

The Client Seed is 000000000000000000074ec3f344eb9e5a3304c77368a8df56a12b0319065fc9, which is the hash to bitcoin block #633568. We committed to this block before it was mined and we created all the server seed hashes before committing to this block. This ensures that we could not control the outcome of each game.

To verify games before GAME #3442359, you can input the Server Seed of your game in the THIS CODE, and you should see the server seeds and game results for the previous 100 games.

On June 24th, 2022, we generated another 10 million hashes with a new server secret key. The public seed is the hash of Bitcoin Block #742123. We announced that we are using Bitcoin Block #742123 in our Telegram channel before it was mined, so that we would not know the public seed in advance.
