Pippellia

Pip (Pippellia) is the co-founder of Vertex, a Web of Trust service for Nostr developers. He builds the infrastructure layer that helps decentralized apps solve their hardest problem: figuring out who to trust when there's no central authority. Vertex uses PageRank-style algorithms to compute reputation scores, enabling spam filtering, personalized recommendations, and impersonation protection. He received an OpenSats grant in 2025 and made Vertex free to drive adoption, prioritizing network growth over immediate revenue.
