How is the Winning Number Generated?

Lottocryptos uses a "Provably Fair" system for its lotteries to achieve transparency in the generation of winning numbers.

The seed of the winning random number generation is composed of four parts:

  • A - Random number up to 128 digits. It is generated weekly when the lottery begins and is different for each cryptocurrency.
  • B - The transaction ID of the last player. The transaction ID of the last verified player of the lottery.
  • C - The total number of lottery tickets sold in the lottery.
  • D - The number of verified players in the lottery.
  • To obtain the seed for the random generation of the winning number, the following process is followed.

    Each part is encrypted with SHA512 and concatenated. Then it is encrypted again with SHA512 and its characters are converted to their corresponding ASCII value. The seed used for the generation of the random number is this value.

    In order to be able to make all the checks considered appropriate, we provide users with the source code used to obtain the random number and the tools to perform a randomness test.
