Bitcoin 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.
