Node Privacy
If you run a Bitcoin node, it's worth being curious about who it's connected to. Your peers are strangers, and any of them could be an adversary. We'll look at what a peer can learn about you. One peer sees your IP address. Several peers can start to guess which of your transactions are yours. We'll explore addrman, the address book your node uses to select its peers, and see how to look inside your own node's addrman and spot anomalies. Finally, we'll look into the current network topology and explore whether node privacy and a healthy network can coexist.
