The initial launchable blockchain lottery model requires participants to hold tickets so that they can definitely compete for weekly prizes, and once a ticket is used for a specific week's draw, it becomes invalid for subsequent weeks.
The ticketing model was designed to meet the scalability gain, given that the blockchain lottery must have a worldwide impact and hold millions of participants over time. Therefore, the draw based only on the number of participants, would not produce ways to add relevance if a player wanted to increase his chances of being awarded, so the participant who wants to increase his relevance within the draw will be able to use more tickets to the draw and increase his probability of gains.
Non-accumulative prizes: unlike conventional lotteries, the blockchain lottery does not have cumulative prizes, all the proceeds are converted into prizes for the participants of the week.
