When you had registered for the challenge and got the participation POAP, I had send you a participation number (XX#). This number corresponds to one of the numbers in one of the charts. Every day we gather data from beaconcha.in, who sponsored us an access to their API for this challenge, to see if your validator managed to have less than <2 missed attestations. If your validator manages to do it, he will move up one step to 30.
This means a S-Tier performing validator will be at 30 points in the chart at the end of November, which makes your validators eligible to get the S-Tier POAP and win the prize. If you think there is a problem with the chart, please reach out to us on our Discord or per email (email@example.com).
