Sure!
During the experimentation rounds (71-73), we have set aside 50% of the regular GIVbacks rewards pool to be used for raffle rewards. The other 50% is still being distributed in the regular fashion as you see here in this post. At the end of each of these rounds, we randomly choose 5 winners and announce them during a live X Space. The number of raffle entries that each person receives is based on the amount donated and the GIVpower rank of the project donated to.
You can read more about it in this blog post:
Let me know if you still have questions and I can help to clarify things.
Once we have completed the experiment, we will be publishing a summary and review of how everything went and have an advice process to decide whether we will fully switch to the raffle model or if we will need to find another solution to our issues with scaling GIVbacks in its original form.
