NIP-34: send patches and issues to repos not yet on Nostr #2050
Vitor Pamplona propose deprecates NIP-31 alts. The main reason is that relying on the writing client to create a text that will look good on all types of receiving clients is the wrong solution. It's impossible to do a good job given the variety of clients today.Other Reasons is Nobody is displaying this; Current alts are generally not descriptive enough and don't really help the user; Clients still need to allow users to easily open the event in a separate client (or njump) to see what it is about; Alts have exposed private information (mostly metadata) before; It leads devs towards unsatisfactory levels of interoperability.
NIP-PO: podcast episodes #2061
feat: add metadata to NIP-47 make_invoice and payment commands #2063
Roland is proposing a NIP which allows storing metadata to give more context for sent/received payments, for example to display zaps, payment or recipient data. This is implemented in Alby Go,Alby Hub,Damus,Rizful,CoinOS (TBC)
