Decentralized truecaller: Identity reputation system / protocol
The problem creepz solves
The primary objective is to become the definitive platform/protocol that establishes the trust worthiness of users in the web2 & web3 public spaces. Interactions can be ajudged in anonymous ways and reputation shared in a zero-knowledge manner.
Challenges we ran into
Implementing zk-proofs and claim validation was tricky. We chose to use PolygonID finally that helped ease the intended functionality.
To solve the cold start problem as well as prevent the recommendation system from behaving in extreme ways, we employed the Laplace smoothing technique.
To prevent abuse, we had to implement a form of rate limiting with the use of bloom filters to save space and reduce gas costs.
