Congrats to the winner. This question might be out of the blue pero may guide po ba dito para makapagconduct ng raffle? Gusto ko lang malaman hehe.
Actually, I first encounter this method of crypto lottery art by
krogothmanhattan (a reputable member here in our community). This crypto lottery art uses the height of the latest block which you can find in the bitcoin
Block Explorer to decide who will be the winner.
As of this writing, the latest block height is 613086, if all the slots have been filled, OP can now decide to roll the next
"deciding block" which is the block height of
613087. In a sense dapat natin hintayin yung block height na yun na mamina (mined) in order to know what will be the hash of the deciding block. Again, OP and krogoth uses the same method of choosing the last digit or letter in the hash to determine who will be the winner.
I hope this helps, baka meron sa inyo magpa raffle pa LOL
