nostr

Hello, everyone! I am Cipher from JoyID. JoyID is a **decentralized**, **non-custodial** key management tool based on mobile **FIDO/Passkey technology**, integrating blockchain wallet and Nostr key management functionalities. It allows users to manage their keys without the need for passwords and mnemonic phrases. We recently added support for NIP-07 and are currently working on implementing support for related protocols like NIP-04. The product is currently in a testing environment.

The first Nostr client adopts JoyID is flycat, you can access it here: [https://flycat.club/en/login](https://flycat.club/en/login) (choose the 2nd connect option). Please give a try, and leave your comments. We would greatly appreciate your help in testing and providing your valuable feedback. 

Thank you very much! 

A new Nostr key manager for ALL, you no longer have to fear losing your keys

I'd like to implement a publishing system with Nostr protocol. However, I noticed most of the nostr clients embed pictures / video clips by external URLs instead of internal nostr uri. 

So is it possible to encode a large file into a nostr message? What's the limitation of the protocol or convention defined? Thanks, guys. 

What's the max message size allowed by NIP-01?
