NostrJoin (Payjoin v2)

A nostr based Payjoin upgrade that does not require the sender or receiver to run their own server.

Abstract

This proposal suggests a new process for exchanging the PSBTs between the two parties participating in a Payjoin. The fundamental protocol stays unchanged and can be found here. Using the novel network nostr would allow participants to utilize a decentralized communication platform to coordinate their Payjoin. Utilizing nostr DMs an end-to-end-encrypted communication protocol between to parties we can create a workflow which is secure and blends into already existing DMs.

Silent Payments notifications via Nostr

This write-up has the goal to discuss the approach of sending notifications for incoming Silent Payments transactions via Nostr. The design is an extension of the discussions around "Stealth addresses using nostr" which had a Nostr-only approach.

The design allows for notifications being sent outside of Nostr so for a clearer structure there is a Silent Payments and a Nostr part. The Silent Payments outlines why the schema is suggested as it is and the Nostr part discusses the using nostr as the communication layer for the notifications.

Silent Payments

Silent Payments offer a novel way for receiving payments without interactivity.
