so pumped for silent payments
https://github.com/bitcoin/bitcoin/pull/28122
going to experiment with an onchain zap spec soon
Discussion

Can you explain? I do understand ECDH, and therefore how the two parties can agree a shared secret even if their communication is public. But I feel like I'm missing some details here
If Alice pays Bob via a silent payment, does Bob need to know that Alice specifically might be sending him an SP? Or can he easily just scan the blockchain for payments to him regardless of the source?
I guess the answer is here in this 'Scanning' section?: https://github.com/bitcoin/bips/blob/master/bip-0352.mediawiki#scanning
To answer my own question. The BIP itself is very clear: https://github.com/bitcoin/bips/blob/master/bip-0352.mediawiki#goals
It's great! Bob can just publish his SP address and can just passively wait and easily (but requiring some computation) watch for transactions that are addressed to him. And nobody but Bob (and the sender of course) knows that this is an SP payment
yeah it's awesome
The best kept secret nobody is talking about :D
Honestly I just want to be able to slap a silent payments on chain address somewhere and then be done with it. make life easy.
From a sender perspective UX is nice but to receive in a trustless way you basically need to run a full node
I may or may not be watching those PRs religiously 🙈
do it!
