The Polkadot Metaverse Championship 2022 was the first event in a hackathon style event series held in Budapest, Hungary between 2022. December 5-7, where KILT Protocol was featured with an invited talk, workshop, and a main challenge proposed from the KILT Team. The organizer team would like to submit a treasury grant to cover supplementary prizes for the participants of the Championship and a management fee for the organizer team.

The Invalid Identifiers team created a solution (concept, github) to the KILT related challenge to enable websites to remove consent popup screens in a GDPR compliant way that is similar to client-side certificates, but the user experience is much easier using the Sporran browser extension.

Sporran has a hierarchical deterministic wallet capable of storing multiple personas. These personas might get credentials from attesters, but they did not focus on that aspect in this solution. What they achieved is that each website gets to see a different DID from the same browser. Note that this is completely the opposite of a facebook like button that BigTech uses to correlate visits of the user on different websites.
