inkan

I agree we are at the stage where I should write up a proper explanation of what I've done so far. I'll work on that.

This sounds like it could turn away tens of thousands of potential Nostr users who'd have liked to use Nostr primarily for vibe coding. I mean if they...

Question for all Ethereum enthusiasts around here: Say you have a smart contract to which users can submit transactions for which they have to pay ga...

I spent nearly ten years in Austin in total. Also three years in Annapolis. Small world.

Didn't know. I did grad school in Austin.

You don't need key signing parties to bind pubkeys to their owners. What you need are pubkeys that have an association with their owners which remains...

They could send me an email at [email protected] or just reply on this thread if they prefer. It's about turning the prototype at www.inkan.cc into som...

In principle yes if there is a very good fit.

Back when I dabbled in the philosophy of mind, I was pretty open to the idea of machines developing consciousness. The philosophical arguments for tha...

"smells like fancy llm talkbto me" That's probably because I express myself like LLMs, always have. They've been diluting my brand.

I was thinking about this just a few weeks ago. I've been trying to build on the Nostr protocol, and the primary engineering challenge has been to ma...

Inkan allows users to record the following types of declarations on Ethereum: (i) Declarations of delegation of signing authority, whereby a pubkey d...

Inkan uses ETH to enable a Nostr key rotation / replacement system. It's not gambling. As for degeneracy, the jury is still out on that one.

Sent test mail to myself. Shows up in Sent folder but not getting delivered.

Thanks. I took a look and nothing seems to be amiss at first glance. My experience with similar-looking websites has been that something ends up not w...

Huh, another thing with 300 million accounts that I had never heard of. I can see how gaining followers for your pubkey could be a powerful motivatin...

Weird yes. Fun not so much.

Late to the party, but I made a prototype of a key rotation system. See below. nostr:nevent1qvzqqqqqqypzp5dxzjv0fvwuym0shmx350573re4t7mpfdm3az6mya7sl...

It's been since the year 2000 for me. If there is a tool you use many hours each day throughout much of your life, you should pay attention to what it...

The pubkey nostr:npub10ukg94kvrvk4qqr3482zdekfsuaw2x56wa899mnpkxqwfxl6dlkqrux0x9 has never ever signed a single Nostr event. Yet that pubkey has re...

Adversaries can now, at the present time, try to discover algorithms that break "quantum resistant" encryption. They may have already discovered such ...

"They just have been battle tested for decades, which is why we trust them." Yes, but it seems that the battle-testing was not really meant to ensure...

"With quantum resistant algorithms, we are not even sure what natural processes need to be discovered ..." I was under the impression that we already...

I believe it's just math -- am I wrong? It's a life dream of mine to learn the basics of quantum computing, maybe enough to understand Shor's algorit...

I remember how weird it was to go back to Windows when I took a corporate job. It was basically just Word, Excel and Outlook but it made the work envi...

Aren't quantum resistant algorithms just math? I'd be worried if we had to "test" them to find out whether or not they work.

This looks like a great movie.

These express intensification, but in the case of "fuck all" it's total absence / nothingness. There's something zen about it.

Yeah, I didn't know it could mean "absolutely nothing." Fascinating.

Had to look that one up. Common British slang is what it says. Something new every day.

Huh, maybe that's why I'm not finding them. I might be back in Japan for a while starting later next month, so that will put me on the inside.

I dropped by at Nostrasia 2025 in Tokyo. Unfortunately I only caught the end of the event since I was busy earlier during the day. It seemed like they...

The killer feature is the method of authentication. But to want it, you have to know a bit about public key cryptography. Not very much, nothing that...

Huh. I was under the impression that I got it to work with various filters without special setup, but I may have to investigate more closely.

Oh, I just started learning strfry for the purpose of using negentropy. Not sure if I'm following the discussion, but are we saying that strfry doesn'...

Same here. There are minimum holding periods before I can move crypto I have purchased to self-custody. It's not really a problem in principle with th...

Yes, I had a terrible time trying to get ETH for testing. I actually don't have any especially good way of getting BTC either. Other people seem to ha...

Yes

Also if you'd ever like to take a closer look, please feel free to log in and poke around. I've put your pubkey on the allow list for the identity fea...

Yes, you may be thinking of OpenTimestamps. And Inkan does in fact use OpenTimestamps to timestamp individual Nostr events on Bitcoin. Inkan only work...

"I can't say I know enough of the technical stuff to know how well this can work in practice." I made the prototype to find out. I've been using it f...

That's why we need a key rotation system that allows you to replace keys that have been lost or compromised. Prototype below. nostr:nevent1qvzqqqqqqy...

Agree, I think it's using public key cryptography for authentication. That's the core of the protocol, and that's what makes it distinctive and libera...

If the above explanations aren't sufficiently helpful, please feel free to let me know. If the product gets misunderstood due to my not explaining it ...

I guess the attestation events can have whatever semantics I want them to have in the intended context of use. For example, if I intend the attestatio...

I have a feature where the client uses only timestamp / delegation info events that were signed by "trusted pubkeys." The trusted pubkeys are settable...

I wonder whether there may be a use for these attestations in connection with the 31045 timestamp events or the 31055 delegation info events that are ...

Took the night train through Transylvania. Just got off. The trees are all ready for spring here.

There is no official spec, but see below for some previous discussion and explanation of how it works. I think the best way to understand it is to lo...

I just found this in your book: "Key rotation is something that we have to figure out if Nostr is going to succeed in the long term. There have been ...

I'd be curious about the quality of the output. In my experience so far, even when programming with AI, I have to stay constantly engaged to give inst...

(... or correct the sentence in the NIP draft ...) 👾

But what is the purpose of slapping the signature onto the proof? I mean nothing further gets recorded on Bitcoin or otherwise proven by appending th...

The notes below have some initial discussion of how Inkan works. The screenshots in the first note contain useful hints indicating what exactly it is ...

I'm not completely following these two bits: -- "you just add the sign to the merkle proof, extending it 1 step" In what sense can one manually "add...

As for this: "Side not on that; when comparing times, the time of the original event might be later than the time of the block the proof for that eve...

Thanks, I think including the signature will be a crucial improvement to NIP-3. FYI, for the example 31045 event that I pasted below, here's the stri...

FYI, here is an example of an OTS event that I think has a genuinely useful shape: {"kind":31045,"id":"7093fe9f8c41bbb8164400b02602692bd231779683ae...

If NIP-3 is going to change, the most important thing to incorporate into the updated specification is that the item that gets timestamped must includ...

In other words, I disagree with the following sentence in your NIP draft: "In decentralized systems such as Nostr, there is no [...] mechanism that c...

Another script is now up on the Inkan website. This one lets users check a given Ethereum block directly to see which Inkan declarations were actually...

FYI, there already exists a key revocation and replacement mechanism for Nostr. It is fully implemented at Inkan. It's a prototype and has rough edg...

I’ve added a Python script to the Inkan website that parses the signed Ethereum transactions produced by the Inkan Management Utility. The script sho...

I would have offered Inkan, but it's not fun. It is however unique.

This is useful for detecting compromised keys. If you've created an identity with Inkan, you can then revoke the compromised key and replace it with a...

Key rotation is already a reality. At least in the form of a prototype I've been using for the last two months. See below. nostr:nevent1qvzqqqqqqypzp...

とても懐かしい。また日本へ行きたくなった。来月行ける可能性がある。

Fair enough - I think I need the signatures for my purposes, but there may be other uses of timestamping where they are not needed.

If both event_id and signature are encoded in a Bitcoin block, you have information about the time at which the signing of the event took place. The a...

I think including the signature records an important additional piece of information. Take an event containing Odell's pubkey that says "Good Morning...

Thanks, I put your pubkey on the allow list. Here's a quick initial tour: 1. Log in with NIP-7 (e.g. nos2x etc.). 2. Do a quick check that you are c...

I think there's something missing here. Another illustration: Suppose it's the gym’s policy that the only persons authorized to use the gym on a give...

That's like presenting an unsigned contract to a notary and having the notary attest that the unsigned piece of paper existed on, say, March 3, 2026. ...

If I'm not mistaken, including the signature gives you evidence that the target event was *signed* by its pubkey at the time at which it was recorded ...

No, your existing keys won't become rotatable. Creating a rotatable identity involves a bit of ceremony. You'd have to use the "Inkan Management Util...

I changed the event kind used by Inkan to disseminate Bitcoin timestamps from 1045 to 31045. These should be addressable events. I posted updated scre...

Inkan enables you to revoke and replace key pairs when your private key has been lost or stolen. You can also perform periodic key rotations preemptiv...

I think we should timestamp "event_id + sig" That's what I've been doing for Inkan.

This uses NIP-3, which I believe only timestamps the event id. If so, I think that's not ideal.

That's why I made Inkan - it allows you to revoke and replace a compromised key pair and keep your followers.

Sounds good.

Well, feel free to point me to a thing you'd like me to look at any time. Of course you may not like the feedback either for any number of reasons, bu...

Same. I started running one inside a VM. Not sure what to do with it. I end up chatting with it, which is sort of besides the point.

If that's the evening you are in a slightly mysterious location. Not quite Tokyo.
