“It is a false premise for some to suggest that exceptions can be made, and that access to end-to-end encrypted data could be created just for those sworn to uphold the public good.
Any process that weakens the mathematical models that protect user data for anyone will, by extension, weaken the protections for everyone. In other words, when you build a backdoor into an encrypted device, anyone can walk through it.”

Updated Nostr Silent Payments gist at the link below.
The gist now includes two example scripts to validate a silent payment transaction and sweep a silent payment transaction. The example scripts have been implemented using the Python standard libraries only (no additional installs such as secp256k1, bech32, etc.) so you can see how everything works from the ground up - even how the public key points are created, added, etc.
Also, the threat model has been updated. Though it can be used by your primary social media npub, that is not recommended.
There are many different use cases (not related to social media) where an npub with a corresponding NIP-05 address may be required to privately receive funds.
