Rings and trees: how to prove coin ownership
2025-06-20 , Main Stage

The current Monero protocol uses linkable ring signatures to prove coin ownership in a way that doesn't leak the specific coin. But other designs do things differently! In this talk, we'll look at different approaches to proving ownership in digital asset protocols: Monero (today and tomorrow!), Firo, and Zcash. Each offers a unique and interesting look at how we can use different cryptographic techniques toward the same goal.

Aaron Feickert is a cryptographer, mathematician, and physicist whose current research focuses on privacy-preserving signature and proof constructions.
