There’s no single best approach to privacy (unfortunately).
But there’s no shortage of interesting ways to break linkability, hide addresses, and obscure tx data in the name of privacy and safety.
In Session 08 of Proof is in the Pudding, David Wong explores how different networks have approached privacy over the years.
From E-Cash and Monero to MobileCoin and Zether, David breaks down blind signatures, Pederson commitments, stealth addresses, and more.
