If you’ve heard about ways that Bitcoin nodes can track you or theoretical attacks against Bitcoin nodes, we’ve got you covered in today’s episode. We’re going to dive into how network privacy works in Bitcoin, what nodes learn about you, and dive into an active attack against your node that’s been going on for the past few months.
Our conversation today is based on the excellent research published by 0xB10C here: <a href="https://b10c.me/observations/06-linkinglion/" target="_blank">LinkingLion: An entity linking Bitcoin transactions to IPs?</a>
