I only have so much room in my life for social media apps. Twitter takes up most of my SM brain power.
Unlike most Nostr users, I actually like having a server and an algorithm. My entire Nostr feed is just stuff about Bitcoin and Nostr. I don’t even know if there is anything else on Nostr. Algorithms show me a wider variety of content, and I don’t want everything to be done in the client.
I am not quitting Nostr, it just doesn’t command a large amount of my attention and I haven’t maintained the same passion for it as I did early

2024-02-20 21:13:42

I renewed my Apple developer account to keep Nostore on the App Store for another year. However I am not a heavy Nostr user these days so I will likely not renew again next year.
If anyone is interested in forking it at some point, I would support that.

Yes that is what I mean. Instead of trying to squeeze group chats into the current way relays work, there would be a new relay structure focused on this use case.
In essence, a server is a meta-relay, and each channel is an individual relay (unique message stream). server.com/bitcoin, server.com/sports, etc are each technically a separate relay. Instead of amalgamating text notes from all relays into a one transparent feed, a client would segregate the feeds based on channel.
There would also be “admin” type events for channel creation, moderation, etc.
In summary, opinionated relays + a tweaked client experience to create a clean chat experience, while still allowing you to build with the Nostr ecosystem of libraries and extensions

New version of the Nomen Explorer out: 0.4.0. The biggest change is it now implements NOM-04, which means the indexer publishes its names to Nostr relays. If anyone wants to build tooling around Nomen names, there is no need to call external APIs, you can just use the same Nostr client libraries.

Hamas is not an existential threat to Israel. This campaign is about revenge, pure and simple.
What is existential to Israel is bombing the population of Gaza to oblivion, committing non-stop terror and violence against the citizens of the West Bank, and uniting the entire Muslim world against them. THAT is an existential threat to Israel, and they have brought it on themselves.

I don’t think footprint is a huge problem with this protocol. On Nomen output is 41 bytes in total. That means if every single person on earth registered one, it would only add 370 GB to the blockchain. It’s not like you need a lot of these names, or need to make frequent transactions on chain. Of course, that isn’t possible, anyway. Long before that happened, a name will be too expensive to register on chain for almost anyone, and they will move to sidechains (I talk about this at the end of the post).

2023-06-01 13:20:05

- reply

It is simpler which is a big win, but the main reason what you said wouldn’t work is because someone could claim a zillion names at no cost and never publish a nostr event to prove it. Then when someone decided to claim a name that the spammer had claimed (he could fit a million in the OTS transaction if he wanted), he could just reveal his first “claim” and rugpull the whole protocol.
In Nomen, there is a 5 byte fingerprint in the metadata. The fingerprint is the first five bytes of the HASH-160 of the name. It’s right there, in the open, on the blockchain. You can tell if anyone has claimed a name you want without publishing a Nostr event just by scanning the blockchain for your fingerprint. No chance of getting rug pulled by a sneaky squatter.

2023-06-01 11:10:27

- reply

I think I just maybe understood what you mean. Yes, I am aware of opentimestamps. What makes it a non-starter is that it is compresses infinite documents into a single hash (as I understand it). This is not desirable because then someone could claim many names at no cost. Which is probably closer to what you meant, I am guessing? If so, yes, that is why I chose the method I did

It’s not just to reduce spam, though that helps. Bitcoin provides absolute ordering. Outputs inside transactions inside blocks, all in exact sequence. This allows indexers to verify who claimed a name. POW doesn’t provide any kind of ordering guarantee

Lol weird bot

2023-06-01 00:29:34

I wanted to share a little bit about Nomen, a new protocol that establishes rules for creating globally unique, human readable identifiers, similar to domain names but without a central planner like ICANN.
- How does it work?
Nomen uses the ordering guarantees of the Bitcoin blockchain as the arbitration method for opposing claims on names. In other words: first come, first serve. Nostr acts as the data layer of the protocol. Records and other data-heavy operations happen as Nostr events on public relays. Indexers, which are the name servers of the protocol, link on-chain claims to related Nostr events in order to piece together a full picture of the Nomen name set.
For a more complete view of the protocol, check out the specification on GitHub. It’s very simple: https://github.com/ursuscamp/nomen/blob/master/docs/SPEC.md
- What’s in a name?
A name is “complete”, so to speak, when there is a claim published on chain with a corresponding Nostr event that contains the records for that name. The on-chain claim is merely an OP_RETURN output, which contains a few bytes of metadata and a 20-byte hash of the ownership information (Hash-160 of NAME + PUBLIC KEY). A corresponding Nostr record event must be published that is signed by the owner of the name, containing a tag with the name that was claimed and a record set. Using the name and the public key, the indexer can recompute the hash and validate that this event is published by the true owner of the name. The record event is a replaceable event, so every time you want to update your record set, you just publish a new record event to replace the old.
The record set is a just a set of key/values that represent the pieces of identity you want published. Some examples are “WEB” for your website, “TWITTER” for your twitter handle, “NPUB” for your Nostr pub, etc.
- The Explorer
The Nomen Explorer (https://nomenexplorer.com) is the first public indexer. Not only does it allow you to explore the existing names out there already, but it has tools to claim a name for yourself and to update your records.
Claiming a name through the Explorer is a trustless process. All you need to do is create an unsigned Bitcoin transaction paid back to yourself (or whoever you want) and copy it to your clipboard. Then click “New Name” in the Explorer, and paste your PSBT into the box. Enter your name and pub key, then submit. The Explorer will add an extra output to the PSBT which is a 0 sat OP_RETURN, and spit the new PSBT back out to you. Load that PSBT into your Bitcoin wallet. You can examine it to make sure the Explorer isn’t doing any funny business (it’s not, I promise!), then sign it and broadcast. The indexer will pick it up after 3 confirmations.
Then you click “Update Records” and publish a new record set. Sign the event with your Nostr extension (Alby, nos2x, Nostore, etc), and you’re good to go. Within a few minutes, the explorer should pick it up and display it in the list.
- Consensus
You might have noticed that, since the claim is published in an OP_RETURN, that means that the miners and validators don’t enforce consensus like they do with Bitcoin script. In Nomen, the indexers are the arbitrators of consensus. This is a looser social consensus mechanism, similar to something like you might find with Ordinal Theory. This has advantages, as you will see.
- Squashing Squatters
Any name system needs to have a way of dealing with squatters. That way may be absolute central control, or letting them run rampant, or somewhere in between. The softer consensus of Nomen provides a potential solution to this problem.
One possible protocol upgrade is a standard for something like a decentralized spam/blacklist for squatters. Indexers could choose to subscribe to streams of Nostr events from trusted parties that handle spammers and squatters. Any name claim on such a spam list would be ignored by an indexer, and the next claim taken as the correct one.
In reality, just the existence of such lists should deter most squatters, since they would need to waste real Bitcoin in mining fees just to try something easily thwarted by indexers.
- Scaling and the Future
The ability to scale these names is important. Every name requires an output on-chain. This isn’t a massive concern (yet) because most people won’t ever need but one or a few of these names. But, still, how far can we scale this?
One example of low hanging fruit is to allow name owners to create sub-names by publishing sub-name Nostr events. These could be useful for families, or for businesses to offer names to their customers. For instance, Bob Smith might register the name “smith” and create a sub-name for each of his children: alice.smith, andy.smith, etc.
Another exciting possibility is to expand the protocol to sidechains, using custom naming schemes. If “smith” is registered on the Bitcoin blockchain, someone else may claim “smith.lqd” on the Liquid sidechain.
The combination of non-sovereign sub-names and sovereign top-level names on sidechains means that this one protocol could potentially scale to the entire world with ease.

2023-05-31 20:09:48

- reply

If I understand the protocol, the ASP does an on-chain transaction for every round. So I guess 5 seconds is fast enough for a payment to be quick on mobile, but slow enough to allow “plenty” of ASPs to operate. Every bit of time you shave is less blockspace available for ASPs.

2023-05-23 12:54:30

The Nomen protocol and indexer are new software, but getting your nomen is simple and low risk.
Using your Bitcoin wallet, create an unsigned transaction paying a UTXO back to yourself. Make sure to slightly overestimate your fees, since we will be adding a bit of extra data to it.
Copy the transaction to your clipboard as a base64-encoded PSBT (this is just a menu option in Sparrow, for example).
On the Explorer, click “New Name” and paste the PSBT into the form, along with the name and public key. The public key is just an X-only schnorr key. You can even use your Nostr npub.
When you submit the form, it will return a new PSBT with the extra output for Nomen. Copy and import it back into your wallet (again, this is just a simple menu option in Sparrow).
Verify that nothing has changed except for the new 0sat output and you can see that no one is stealing your funds. Then sign it and broadcast it! That simple, really. Low risk.
You can then publish a records Nostr event #note1tx8…xsqw
