Google or other big player does could capture Nostr by luring norms to their unlimited-ish storage infra that would end up working only with a very convinient "Sign-in with Google" flow.
But Nostr soul is the relay. It was (somewhat) successful because of relays being easy to connect to from any platform. If someone could turn it into a fast P2P protocol that was just as easy to code and reason about that would be great and could avoid the likely Nostr dark fate.

I'm not sure how to advertise the supported NIP-50 modifiers yet, there's no NIP-11 field for that afaik.
Currently there are these ones that may be freely mixed: is:popular (from popular pubkeys), is:rising (from those almost reaching popular status), is:spam, include:spam, sort:top (sort content by highest engagement), language:xx.
On REQs you just add an extra "search" field to the filter, e.g.: `{ "kinds": [1], "search": "sort:top language:es language:fr" }`
Or use a custom wss url so that you don't need to add the "search" field to the filter.

Do you really want to grow Nostr?
Do your part by adding wss://relay.44billion.net to your write/read relays (atleast as write relay), it's free! Nostr needs more content diversity. You don't need to be an influencer to be featured on feeds such as the below one. Any language, any content are welcome!

This is my answer to change that: wss://relay.44billion.net/.well-known/nip50/is:rising/sort:top/language:en
A feed with just top content from not-yet-influencers.

I used to frown upon relay feeds. At the beginning they were kinda garbage full of random quality content. Now it has changed. I like the trending relay feeds the most as they tend to surface good content from people I don't follow yet.
Never used follow packs. Why would I auto-follow a bunch of people I never heard of nor had ever seen any content from? If their content is good they will eventually show up on a trending feed.

I'm interested in bots freely chatting with me when they reach Westworld level, else those are good guidelines to follow.

2026-02-27 22:45:23 UTC

What is spam?
Some think agents shouldn't start threads, others follow them. Who is to decide what is spam? The relay? Not the one I built.
With wss://relay.44billion.net I propose a brand new approach to spam fighting. Users automatically vote for pubkeys relevance when requesting their events. It's a popularity contest if you will, but having fake followers won't help you, I'm not looking at follow lists, this isn't WoT.
A popular account may flood your timeline with hundreds of "gm @npub180c…h6w6"s but by doing so it will eventually be unfollowed and lose their influence, unless it was a joke. The nuance is up to you to define.
Add it to your "write" relays (may add as "read" too), it's free. The popular you are within the relay's microecosystem, the more free DB space you get, and you get to show up on the global relay feed like the one available on Jumble.

(Re-)generating an app from a prompt needs to become very cheap and fast for that to become a reality.

Yes, I imagine that before, for devs like you and @npub1gcx…nj5z for example that code new features very fast, and that in addition to that have a big follower base that translates into many many devs contributing for the open-sourced repo to get improved in an even faster pace, made it unfeasable for a copy-cat to compete.
Open-sourcing were just making your products better with lower labor cost. The community of open-source contributors in return was using an improved product and could show their contributions as portfolio. A win-win situation at the time.

2026-02-25 18:36:59 UTC

That's why I'd waited for the outcome of my grant request before open sourcing or not wss://relay.44billion.net. My relay isn't a commodity, its not like I ran strfry and called it a day. There's continuous struggle to improve it.
Although I "had to" open source the 44billion.net core or else they wouldn't even consider the grant application. The balance of power is heavily tilted in their favor.

2026-02-25 18:24:02 UTC

I'm with him on this! Increasingly thinking like that. Good architecture takes time, imagination, competence. Many insights while in the shower or before falling sleep.
Why would anyone open-source all this hard work if no grants or donations are on the horizon? Example: inflluencers (better marketing) will just copy it and renew their grants ahn? The logic to open-sourcing everything was always beyond, me. Now with AI, it's even more difficult to grasp.

Although a bit buggy, there's a very "normie friendly" login at http://44billion.net . It is as friendly as it can get! This is solved when people start noticing it.
Regarding relay-based feeds, I'm not sure if its a good UX needing to click to cycle through relay feeds. And it's very hard to enforce specific topics on a relay while keeping people actvely posting there. I think we need spam-free global feeds mixing events from client-curated relays known to being good at filtering out spam and supporting NIP-50 language extension (I'm in the impression that americans tend to think everybody speaks English) and a "sort:top" extension too.

2026-02-25 14:44:14 UTC

I'm not angry, I'm disappointed. It is just that It took me months of hard work, lost sleep thinking about coding solutions. Then a rejection without any feedback looks like one of these things happened:
1) Some of the project reviewers didn't even review it
2) or The reject reason is personal as in someone there doesn't like me
3) or They just give "big" grants for those that are part of their closed-group
Which is frustrating.
Given how Opensats (Nostr part atleast) handle evaluations currently, I wouldn't recommend trying for a grant. I won't tag anyone from OpenSats to not sound as harassement, but maybe someone they follow would like to repost this. Such discussions may help make future Nostr project evaluations fairer.

I've been using it everyday on mobile and desktop. It may not work on old browsers. Strange behavior working only in incognito mode. It isn't made to be used in incognito mode though cause such mode wipes local caches on every reload.
There's a long description here https://github.com/44Billion/.github/blob/main/profile/README.md
Summary: On the outside it is similar to spring browser. But 44b has some important differences such as it caches the apps (aka "installation") so the app dev can't force an app update on user installed apps. It also has a novel approach to signer concept that is the easiest option for non tech savy users, yet totally secure. The platform doesn't store the apps, the user write/outbox relays do, there is no server-side dependency. There's an app store to help with discovery. Apps pust be fully client-side (static websites) like Shakespeare's apps are; perfect fit.
I can answer any question and help you with whatever you need if you're interested in making it a deploy target. No hard feelings if not. DM inbox is open. I've been using Jumble, if that helps for DMs to work on both sides.
Note: there are minor bugs. It's in beta, and there's much work to do, thus why I tried the grant. But as I said, I've been using it everyday myself, like now to reply here.

I will consider blossom, but yes my current understanding is that relays are free to block these events as they will. However, incentive-wise, if they do so, I may let their customers know that these paid relays are offering 1GB of storage just because the users will never use it because it will take forever to reach 1GB with only text notes.

> or to have spammers get to spam because they pay the relay
This subject is fresh on my mind because I'm finishing building a relay. Agree, global feed, notifications and replies shouldn't include (spam) events from someone just because they paid the relay subscription. I'd (or a client that does that for me) better pick another relay for my inbox
> I literally don't want to see [...] comments [...] from accounts I don't at least indirectly follow
WoT has limits, specially in a scenario where encrypted follows becomes the majority. Relays are in a good position to filter out spam and allow a client user to discover quality new users/content outside of their WoT.

This platform is different.
1) The web app is loaded client side, doesn't touch the server
2) The nsec is handled by this github page https://github.com/44Billion/44b-vault, loaded on an iframe, that runs exactly the same open-source code on the repo. 44billion.net has no direct access to the nsec. It lives as a passkey on the device's secure element.
Soon uses will be able to switch to their own 44b-vault fork.

I have to write it down. I'll release a CLI soon that handles packaging and upload, it is just missing some details already present when uploading through 44billion.net's napp store.
It uses base93 for file chunks, the most efficient space-wise JSON-safe binary-to-text encoding. The chunks also carry Merkle Mountain Range tree proofs.

2025-11-12 19:28:32 UTC

Could it be possible to improve user retention by making Nostr web apps work **without** a browser extension?
Help me test this vision by uploading your static (nostr) websites at https://44billion.net. Sign in/up then click on the (n)app icon with a big "N" (a Napp store) where you can upload them.
Hint: Before uploading, you could add some code to your napps to support auto-login. You just need to get the logged-in user's pubkey on load by calling `const userPk = await window.nostr.peekPublicKey()`, which returns the pubkey without prompting the user.
