Your Crypto Transaction Isn't Private — Even When It Is | Corey Petty
Is a crypto transaction really private if the transaction itself is hidden — but someone can still work out who sent it, when it happened, where it came from and who processed it? Dr. Corey Petty joins Dads Gone Crypto to challenge one of the biggest assumptions about blockchain privacy. Corey is Chief Evangelist at Logos, a long-time blockchain security researcher and an early voice in the Bitcoin and Ethereum ecosystem. His argument is simple — and uncomfortable: Crypto may be protecting the transaction while exposing everything around it. Watch the full interview: https://youtu.be/ULKHR5jpnmQ In this episode, Sean and Ryan explore the difference between transaction privacy, metadata privacy and operator privacy — and why that distinction becomes increasingly important as banks and institutional finance move on-chain. We put institutional blockchains such as Canton Network under the microscope. Canton uses selective disclosure to protect sensitive financial information while maintaining the auditability and compliance institutions require. But is selective disclosure enough? Or can transaction timing, counterparties, infrastructure and network metadata still reveal information worth millions to competitors, analytics companies or governments? Corey walks us through the lifecycle of a crypto transaction — from the first message between two people to final blockchain settlement — showing where information can potentially leak before, during and after the transaction. This isn't a Logos versus Canton conversation. It's a much bigger question: What does “private” actually mean when the world's financial system starts moving on-chain?
