Bit555 has used the Bitcoin transaction hash generated at block height 729650 as the salt of crash to test the provably fair.

Our Crash is ready. We have completed more than 10 million hash calculations, determine the initial server hash,  and will use the 10 millionth hash as the hash of the first round of Crash. 10 million hashes are released from back to front to ensure that the server-side hash has not been tampered with in future Crash games.

Bit555 will use the 730111 block high hash on the BTC transaction blockchain that has not been mined as the Salt of Crash to strengthen the unpredictability and randomness of the game results.

Finally, the HMACSHA256 encryption algorithm is used to calculate the results of the server-side hash and Salt, and the result is used to deduce the final result of the Crash game.

For more detail verification steps, please check in the game!

Bit555 will use the Bitcoin transaction hash "00000000000000000004aa43bb3f52af890f23a564a85b77a849c991f5a9702a" generated at block height 729650 as our salt to verify the fairness of all original games.

Bit555 has decided to use the transaction hash generated when the Bitcoin block height reaches 729650 as our salt to verify all original game’s fairness. At the time of selection the block had not been minted yet, hence, it proves that we have not chosen that block on purpose to benefit us in any way. This was done to ensure the integrity and fairness of the games as hash is completely unpredictable and cannot be manipulated or tampered.
