What is a "paynym"?

[Kruw]

I like the idea behind PayNyms but for some reason they never got very popular with Bitcoin community.

BIP47 Paynyms aren't popular because of the notification transactions/trusted third parties involved, undermining the attempt to accept donations privately.  Silent Payments (BIP352) is the proper standard for stealth addresses that doesn't have these downsides: https://github.com/bitcoin/bips/pull/1458

Does anyone know which wallets have Silent Payments/BIP-352 already implemented in their UI, or which wallets have it in development?

I believe it could be such a useful tool for groups of people that require more privacy and anonymity just like the Truckers' Protest, to avoid govenment sanctions. Bitcoin would have been the best use case for what they needed because the banks/donations sites disallowed them service.

Although some people considered it a failure, it would have been a success if Silent Payments + layering that with Lightning, and CoinJoin were used?

Silent Payments support is being developed for Bitcoin Core, it's on the wishlist: https://github.com/bitcoin/bitcoin/issues/28599

Here is the tracking issue: https://github.com/bitcoin/bitcoin/issues/28536

And as you can expect, that made Samourai extremely pissed since people will actually gain full privacy from their stealth addresses with BIP352 Silent Payments instead of having users' donation info stored and tracked by their BIP47 Paynym server: https://twitter.com/SamouraiWallet/status/1666404283208572933

Hopefully the Core Developers hurry it up and have it merged as soon as possible.

I have a hypothetical question for you. If BIP-352/Silent Payments was implemented, and the Trucker's Protest used it to receive donations, then decided to send those outputs to Wasabi CoinJoin for further anonymity, would the blockchain analysis companies working with Wasabi have the ability to detect them, or would BIP-352 actually be good enough to protect users' privacy?

If a a blockchain analysis company was previously targeting a static donation address, a BIP352 silent payment address would stop them from being able to determine which coinjoin inputs were donations. This does not guarantee donations are not sourced from already blacklisted entities.

There are none.

Absolutely. But BIP47 or hosting a payment server that generated a new address for each deposit would have achieved the same result.

If BIP-352/Silent Payments was implemented, and the Trucker's Protest used it to receive donations, then decided to send those outputs to Wasabi CoinJoin for further anonymity, would the blockchain analysis companies working with Wasabi have the ability to detect them, or would BIP-352 actually be good enough to protect users' privacy?

No one knows. Wasabi will block whatever their government buddies tell them to block, and they won't give any reason for doing so. No point in risking it when you can just use JoinMarket or Whirlpool instead.

OK guys, I know silent payments and BIP352 are nice and all, but this question (and also the one asked a few days ago) have already been answered, so I'm locking this thread before it turns into another Wasabi and Samourai battleground. You can start another topic to continue the discussion if you guys want to. Thanks!
