We are publishing the cryptographic commitment for our upcoming Crash game chain before any game results are generated.
Chain length: 30000000
Chain tail hash: 22ceeaa895da52c28390fa08105811145747e95eb66b1c1fcd431e6594aac035
Future block height: 965022

The game hashes form a cryptographic hash chain. Each subsequent hash is generated by applying SHA-256 to the preceding hash's 64-character lowercase hexadecimal representation encoded as UTF-8.
The hash of Bitcoin block 965022 will be used as the seed. Since this future block has not yet been mined, its hash is currently unknown and cannot be selected by us in advance.
Each game result will be calculated as follows:
Code:
Bytes        hmacBytes = HMAC_SHA256(gameHash, seed)
Integer      int = parseInt(hmacBytes[0..3] as 8 hexadecimal digits, 16)
Number       crashPoint = (2^32 / (int + 1)) * (1 - 0.01)
Result       finalResult = max(crashPoint, 1.00)

Bitcoin block 965022 has now been mined. Its block hash is used as the seed for the previously announced Crash game chain.
Code:
Chain tail hash: 22ceeaa895da52c28390fa08105811145747e95eb66b1c1fcd431e6594aac035
Block height: 965022
Seed: 00000000000000000001f885b8393e7edd786f154f759433f16ffb38223ac83c
Block verification:
https://mempool.space/block/00000000000000000001f885b8393e7edd786f154f759433f16ffb38223ac83c
Each Crash result can be independently reproduced using its revealed game hash, the Bitcoin block hash, and the previously announced formula.
