Silent Payments (BIP352): a way to share a static Bitcoin address without destroying your privacy

Most of us have been in this situation: you want to share a Bitcoin address on your website, your Nostr profile, or your email signature — but you know that a static address is a privacy nightmare. Anyone can see every payment you've ever received.

Silent Payments solve this elegantly. One static address (sp1q...), every payment lands on a different on-chain address, completely unlinkable. No centralized servers, no notification transactions, no coordination with the sender. Just cryptography.

I wrote a full technical breakdown covering how the ECDH derivation works, current wallet support (Cake Wallet, Dana, BlindBit, Sparrow), the scanning tradeoff, and how it compares to BIP47/PayNym.
