I’m not sure about pioneers and villagers… just drawing on insight from jobs to be done theory by Clayton Christensen
People need to have a problem before they have enough awareness to begin searching the market for alternatives and substitutes.
I agree there’s a lot to be built, but simply building stuff nobody is looking for isn’t going to create demand.
If there’s a bunch of people who get censored, or lose access to an api they built a business on, or some other side effect of centralization, it’s better to build features for that group of people that currently in need and searching for alternatives.
People didn’t join nostr in the early days because primal was feature rich and ready with a good UX. They joined because twitter failed them and they were willing to deal with rough edges if it meant they wouldn’t get burned again.
There’s a million things you could theoretically build, so why not build the things people might be looking for right here and now?

2026-06-03 02:24:40 UTC

- reply

I actually think the opposite is better. You're basically saying if you build it they will come.
I think if they come, we will have a better idea of what needs to be built.
Let demand shape supply.

to be clear, i think its only "dead" if nobody uses it.
but... i would consider anything that has organic growth to be "alive".
like nobody has to go around and http/smtp-pill people anymore. those networks have network effects and grow and sustain themselves on their own.
maybe we're just incubating?! it still feels early, unpolished, and without any sort of product market fit.

People thought they understood numbers before too. Then people discovered concept of zero which introduced negative numbers…
I don’t think we can ever say for certain that there is nothing left to discover in any domain.

I can definitely understand this from your side of the equation. I would prob trust a some stranger enough for them to hold a little of my pocket change.
But even if they are trustworthy and not a dick, i doubt its profitable to run a mint for people's pocket change. I imagine if routing fees are gonna float you, you'd need much larger reserves.

Great observation. At this stage nostr needs retention more than interoperability.

Not to sound like a dick but why would any of those people run a mint?

2026-05-25 16:00:28 UTC

If I understand it right, in the US any business that would run a mint would have to obey KYC/AML laws because they have unilateral control of funds... yet would be unable to comply due to the nature of ecash.
I think this is a non-starter for many businesses.

2026-03-08 20:11:33 UTC

Interesting. Will have to do some thinking to see how it lands here.
First impression is that L402 is “closed” as in every service provider can set their own rules, yet “permission-less” since no third party is needed between buyer and seller.
I could be wrong… dumb human here. Consult Claude for higher level thinking 😅

2026-03-08 19:46:14 UTC

- reply

Also, ai agents are indistinguishable from humans. Service providers don’t have to care who’s on the other end if they can prove they paid.

2026-03-08 19:44:44 UTC

- reply

The macaroon spec has been pretty formalized by Google since 2014, but really there hasn’t been enough adoption to uncover or establish best practices.
But, if successful, one can easily imagine interacting with all their web services as if they were cash businesses.
Pay, get access to whatever you paid for. No need for service providers to build a “user” table or collect payment info. The authorization token with each request tells the server everything it needs to know. Totally stateless.

2026-03-08 19:36:00 UTC

- reply

As far as I can tell, you’re good!
IMO the real rabbit hole for devs selling services to humans or agents via L402 is macaroon construction.
Basically in exchange for sats, what does the token grant access to and how much/how long?
It’s not rocket science, it’s just different reasoning than most devs are used to.
Kinda like bitcoin or nostr, you need to unlearn a bit before you can appreciate its design.

A bootstrapper's only job is to build their idea and test it with the free market.
Bitcoin removes nearly every point of friction.
New ideas don't need a registered business and a bank/stripe account.
Bitcoin and the internet has no boarders, you can reach customers in every country.
Savings grow instead of getting inflated away. Raising money becomes a choice, not a requirement.
Your customers will have a killer UX. One click pay/onboarding. No reason to sign up yet another account with Nostr and L402.
And with AI agents, your total market grows faster than the human population.

"Better" is different for everyone. Everyone's risk/threat profile is different.
If you don't trust Primal at all then its not better.
But generally speaking, its easier to build trust with one service provider than a constantly changing set of relays your client is auto connecting to and and doxxing your IP with.
At least nostr gives us the choice to choose our own adventure and solutions.
