most nostr apps you can click a single button to create an account, since it just generates a keypair. no email verification, nothing. what is simpler than that? you don't even need to know how to host something on a server, the relays

I have had the experience of explaining to coworkers how bitwise operators even work more than once. I think sometimes people overestimate the average programmers knowledge when it comes to bit operations. modern programming is so detached

I will remove the novel wording just for the hacker news geniuses. I have been programming for 26 years and have never encountered this pattern, nor could I find it in any libraries, which is why I decided to wrap it up in a library. If a s

Images are not stored on relays, so they would not be targeted. The image hosts have the liability, not nostr.

There is no "zaps balance". Zaps are just receipts of lightning payments. The basic idea is that a lightning node will detect when the invoice with a nostr note inside is paid, and then send the receipt to nostr as a nostr note, w

Zaps just put a signed nostr note inside a lightning invoice so that clients can show that a specific user send some amount of money to some note or profile. clients request lightning invoices via lnurl (an http lightning specification). Yo

I guessing this is because you are used to an algorithm that is constantly showing you the most liked content. average day to day discussions between humans can be pretty shallow, nostr feels more like shooting the shit with your friends in

Correct user counts need to have a web-of-trust applied if you want an accurate count of "real followers", but I suspect that's the same on X as well. As one of the largest accounts on nostr I can say there aren't many &

I don’t think it’s important to dive into tech details on the damus homepage. Gmail doesn’t attempt to explain the email RFCs when creating an account.

Damus does not manage your lightning wallet. All it does is open lightning invoice links in an external wallet when you want to zap someone. All of this is optional and opt-in.

Its optional, you don’t need to attach a lightning address to your profile and you will receive no bitcoin for your posts.

Author of damus[1] here. We’ve seen a crazy growth in nostr in the past couple of months. Damus itself sees about 1000 to 10,000 download per week, and we’re up to about 500k to 1mil+ users (hard to get exact numbers on a decentralized netw

It's only recommended that you store json and text on relays. It's a text protocol, not a protocol for storing large binary data. Note sizes are restricted as well on most relays.

Hey, author here. This is built on the nostr[1] protocol which has many advantages over activitypub. I highly recommend reading the readme on the github for motivation on why we would need yet another decentralized social media protocol. Ha

You can do this with Trezor. It allows you to enter a 25th word to your seed when you unlock it (it looks like you're just entering your password, but you could enter any password), generating a whole new set of private keys. Although

I use a Trezor to store my PGP key. I never have access to the private key, it's generated by a seed which I backup in a cryptosteel protected by a password in my brain (to prevent physical theft). The device only provides an interface

Nix has a way of doing this as well, just needs a better UX (like most of nix).

Indeed, this quickly becomes obvious after writing Haskell for awhile. Lawless typeclasses just seem clunky and get less reuse compared to their lawyer'd up brethren. You also can get a very slight taste of this in C#, Java, etc as wel
