To build an effective, scalable, nostr, we need to go back to first principles. Brain dump:
- The web is based on the URI, HTTP and HTML
- It is the URI that ties the whole web together aka The Hyperlink
- Adding hyperlinks to a document or data allows it to be web scale
- The web enabled a syntax to allow hyperlinks to be added to docs
- The web enabled a syntax to allow hyperlinks to be added to data
- Data and documents are different things
- Data is real data, meta data and headers are for documents
- Hyperlinks are global variables aka super keys
- Typed links are also part of the web
- The order of hyperlinks is generally not recorded in a document
- All hyperlinks in a document form a Set
- Nostr is a subset of HTTP, using the websockets protocol
- Nostr transmits notes from one user to another, using relays
- Adding hyperlinks to nostr allows it to be web scale
- Data should be separate from transport
- Nostr has unique users which are also a pubkey
- A user can have a list of things as an array
- An array of things can have a user
From these simple principles a web scale flavour of nostr can be delivered

Agentic Nostr is close to achieving AGI. The next phase will be to add payments to agents, and then, everything.

Agentic #nostr is the big idea. OpenAI may get 25% of revenue for agents charging $2000, $10000, $20000 per month. But it will be on their own rails. Nostr is public infrastructure for an agentic future.

Sorry to hear that. If you mean MaxCoin that was not "his" coin. It was in honour of him. They state this somewhere. Not even sure that was premined, but it did have a big reorg. I think they have some novel mining algo. I actually think MaxCoin is OK. But he probably didnt want to debate about it being "his" coin, for the Nth time. I met Max and Stacy at the first bitcoin conf. that we organized. I helped them recover their lost coins, after hd failure -- they didnt even know it was possible. Sounds like a misunderstanding. They are very good fun if you meet them.

Max and Stacy have an orange pill podcast telegram channel, so you could ask them! IMF doesnt really want to see a bitcoin standard. They make too much money from the current fiat / national debt based system. Even when bitcoin was legal tender in ES the chain was not full, before inscriptions came along. P2P electronic cash can be done on side chains, liquid, or with merge-mining scale to billions, while having more security than the incumbent financial system.
As it happens, I just went on their channel and the most recent meme is below 🤣

#bitcoin doesnt need a soft fork. Bitcoin has quite a lot of privacy built in. Much more than its fiat competitors. Privacy solutions can be explored without a soft fork. For example, with merge mining. Or privacy can be done at the nostr layer. But there is not much appetite for this, so far.

2025-03-04 23:11:11 GMT

#bitcoin doesnt need a soft fork. The current feature set is barely used. Especially when combined with nostr. The bigger danger of a contentious fork, which some are pushing for, incluing some "celbrities", is another civil war, which leads to a chan split. Even the perception of a civil war will be bad for bitcoin.

All Trump has to do, to solve the national debt problem, is to instruct the treasury to pay the interest on the debt, instead of the tax payer. This would be a slow mend, over 30 years. And there would be little to no inflation because the money supply has already been inflated at the time of debt creation.

Bitcoin is just the beginning. So much more can be done. I have been fighting for over a decade to add a social aspect to bitcoin. Nostr, while not perfect, is the first try at that. Now consider how much more can be done. Ask yourself why bitcoin is special. It is special because it is not rigged. A non-rigged ledger is just the first use case. What comes next is a non-rigged market (ie an actually free market). We've only realized a fraction of the utlity of bitcoin, and that provides lots of opportunities!

2025-03-03 08:17:48 GMT

Once a country has a bitcoin reserve, it can effectively sunset it's fiat debt, by issuing the exact amount to pay it off, as it comes due. The country then transitions from net liabilities to net assets, leading to a new economic prosperity. Trump actually gets this, where most mainstream economists, do not. I guess he has lived in the world of debt his whole carreer. I have to say well done, on this point.

2025-03-03 07:27:24 GMT

By the way I think techniques like this will become invaluable for projects like bitcoin. Especially if we can learn to subtract biases introduced by the group think. If bitcoin development could return to its roots of logical arguments to optimize the system, rather than, advocacy and politics. We could pave a cow-path towards ossification, while mitigating major risks, such as a chain-split.

Frostr is the first project that really takes advanteage of the fact the Nostr uses Bitcoin taproot for identity. While taproot identity is 100x smaller other key eco systems out there, it does have the small advantage of bitcoin identity being adjacent. Frostr is the first project that has finally noticed this, and is starting to explore what can be done. I wish them success!

Yes, that's a very good point. There are essentially two ways to do it, one is with HD keys, and one is open ended. Each has trade-offs on complexity, utility and security.

"In the early stages of the XRP Ledger's development, some data was not permanently retained because the ledger was undergoing testing and refinement"
Is this statement in any way believable? We're talking about the full chain of custody of the first 100 billion XRP. Does any of the github issues at the time match this explanation. Go check. (Hint: not they dont).
Now for the brightest of red flags. Would any software *ever* delete records? Would any coder ever do this? What does "readily available" mean? But dont take my word for it. Put your analytical cap on and see if you think the explanation holds up.
This is the story they foist on people to cover their tracks. But it has as many holes as swiss cheese. Verify, dont trust.

Dont forget that XRP destroyed the first 32,000 blocks enron style, so that they could never be audited. It then became impossible to verify the chain. Ever.

Bluesky growing fast. I hope that nostr can capture and retain some of these users, in future.

Not too sure about that. How to verify? Tor is heavily monitored, both internally and via exit nodes. Though I agree in principle that the more honest nodes that use it, the better in theory, it should get.

Its been talked about for years, but never got through the NIPs. Put latest block hash in the event and prove a message came after a certain time. You can also timestamp an event to prove it existed before a certain hash. If you do both you get an interval. It turns out that is enough to create a smart contracting system. No client does it, yet.

> My point has always been there is no reason to do this contextual lookups when we could have the no-context lookups.
Bingo! That is what makes the web work. Few know this but the "U" in URL orginally stood for "Universal". You can of course use URLs without DNS, and DNS is just one option with a large network effect.

Smart, but easy to game. There's other ways for the user to mark the correct edit. Edit is actually the killer feature for nostr, if done right. Opens the door for whole new branches of innovation.

Correct. We could have key rotation, but no one seems to want to implement it.
