Peggy's unique approach with the digital fingerprint means artworks can be verified and traded by anyone (not just galleries or auction houses). This is a game changer if I want artworks to be resold, while also receiving a royalty. No other site does this. The app itself is elegant and has lots of social features which make artist and artwork discovery fun and natural for the collector. When new artworks are added, collectors who "follow" get notified without any extra work. And when works sell, the auction timer lets other interested collectors jump in and place an offer too, sometimes resulting in organic bidding wars and higher prices.
