There’s a new bitcoin cash lottery that uses the BCH blockchain as an oracle to provide true provable fairness in the game. Participants toss BCH into a pot and if the last few digits of the user’s transaction ID matches the target block’s hash they win the jackpot.
Bitcoin cash supporters have been discussing a new type of lottery system that uses the BCH chain to operate in a transparent fashion. Nakamoto Game was announced on March 6 and allows anyone to participate without registration. Basically, a user chooses to send a bet for 0.01 BCH or to place multiple bets by using the scannable QR code. The last alphanumeric digit of the transaction ID (TxID) that the user generated by sending BCH is their lucky number. The system uses a block height every three days which requires 400 blocks to find out the winner of each round.
