I do have one thought where someone can sting you (ish) with this (if I understood it right):
(Let's assume I'm a jackass government mr.joe)
- I can send 0.12345678 BTC to a silent address
- Look up the same amount sent to get a public address that the receiver controls
- At this point, I can harass the receiver about that exact money.
- I could also wait and see if the receiver may combine all of their coins from all of their addresses into one and start questioning/harassing them about it, which may lead to confirming all of what they have received from the silent address. (The receiver may not do this, and if they do they can play dumb and say "I didn't want my money so I picked a random address and sent them money there").
- I'm not saying SP is bad, in fact, I think it's a great layer and I'd want to use it. I'm just sharing my thoughts/concerns.

quotingBitcoin silent payments have been maturing, and there are already wallets that support it, such as https://app.silentium.dev.

Silent payments are a type of payment that can be made to a unique on-chain address for every payment, even though the receiver has provided the spender with a reusable (off-chain) address. This improves privacy.
Keychat's continual update of receiving addresses is somewhat similar to silent payments, with the goal of avoiding address reuse to enhance privacy protection. Both use ECDH, but the difference is that Keychat's update of receiving addresses is interactive, while silent payment is non-interactive; the recipient needs to scan all transactions to find those that belong to them. Interactive updates are more suitable for chat scenarios, while non-interactive updates are more suitable for transfer scenarios.
