I just started to use Amber instead of directly giving my private key to Amethyst... wow... its like... wow It even has offline version. I love it! Its my guardian angel. I can accept or deny whatever i want for each client. I am very impressed in Nostr and its ecosystem. I am gonna start making donations. I just need to figure out that... bitcoin wallet thing? bruh. i don't even know why bitcoin though... but anyways... as far as i can make donations its not important to me I am gonna use whatever client i want with no trust issues. Thank you everyone who made this possible! I am also gonna introduce Nostr to my turkish friends

Disclaimer: I am not cryptographer. I really don't know why Nostr's NIP-13[1] is using the leading zeroes approach for Proof-of-Work. Can't GPUs just eat this approach of PoW very easily? I thought RSA-based time-lock puzzle[2] would be the correct approach? There are also Wesolowski and Pietrzak VDFs (Verifiable Delay Functions). But we don't need them here for relays, right? Because only relays need to generate and verify PoWs? And RSA-based time-lock puzzle's implementation is much easier. Am i wrong? [1]:

NIP13 - NIP-13 - Proof of Work

There is so much going on in Nostr and i am still trying to deal with it lol ;-;
