Ark is cool, but the biggest concern for me is the capital requirement.
To put it into perspective, to achieve Visa scale, the ASP has to anticipate 1 month of payment volume, which is roughly $1T.
In the case the state is weak, Ark can work, but fedimints work even better: scale much better, are more private, and high competition keeps everything in checks.
In the case the state is oppressive and strong, Ark is fucked because only a few companies can have that much money, which means the state can go knock on their doors.
very noob nostr "dev" question here #asknostr
I am using the python nostr-sdk, and the documentation is seriously lacking (or I couldn't find it after some hours which would be bad).
How can I turn a PubKey() object into an npub?
with to_hex() I get the hex version, but I want the npub...

- Money wants to be one, so a multi coin world is very unlikely
- exchanges from BTC to XMR are single points of failures
- Lightning gives you privacy and plausible deniability, unlike Montero
- Trying to be ASIC resistant is a big bet, that might blow up catastrophically, and requires centralization of protocol development
- with the same level of txs of Bitcpin, running a Monero node is way more costly

> but i think we are long past the point where there is an economic value in offering an aggregation service
Maybe, idk. I think there is value in providing that kind of infra and service. But the customers I see are clients, not users.
> maybe cache.nostr.wine or whatever it's called, cellar?
Will try that! thanks, and thanks a lot the reply 😉
Yeah, this thing is wild, everything is shit and amazing at the same time
focus your energy, prioritize what's essential, remove the non essential and work.
You work, you stack. Over time this is the winning strategy
As predicted, eventually someone with laser focus (not laser eyes) will enter the Bitcoin market, and make the process of controlling and using Bitcoin as easy as WhatsApp, without compromise or the need for any education.
Bitkey is the first global scale company to achieve the hardest part of this. The focus - very sharp, the user experience - extreme simplicity.
By removing all "thought barriers" from its operation, people using this device and service can just get on with using Bitcoin. That's more important than anything. It is a beautiful mix of safe storage and everyday use.
The vast majority of users on Earth will never read about Bitcoin just as they have never read about SSL or POP3, but everyone is using the web and email.
This has to happen in Bitcoin for it to reach and touch everyone, and it has to reach and touch everyone for it to do the work it was designed to do.
This development, like Bitcoin itself, starts off quietly, then all of a sudden, it's everywhere, with the side effect of forcing everyone to rise to its high standards.
As it was with the iPhone, before it, all phones had mechanical push button keyboards. Then, seemingly all of a sudden they were all relegated to the dustbin, and the expectation was "keyboardless".
You're seeing the beginning of something like that here with Bitkey. This single event could be the beginning of the very much needed sea change in the thinking behind delivering Bitcoin services to the public.
Well done that Bitkey team!
I disagree.
2 of the 3 keys are controlled by Block (1 in the App, 1 in the server).
That means that block can rug people, if pressured by the government.
Furthermore, all transactions are announced to their server, which means bad bad privacy.
They have optimized a signing device which is supposed to be for savings, for spending.
It's like putting a fridge in a sport car.
A fridge is useful, a sport car is cool, you combine then and you get something ridiculous
Hey nostr:npub14q8uffuxxnhzd24u4j23kn8a0dt2ux96h5eutt7u76lddhyqa0gs97ct2x, Iis it this geyser page yours?
https://geyser.fund/project/pleblol
If so, it's probably a good idea if you log in with your nostr profile, so people can check that it is indeed legit.
(I work for Geyser 😁)
I am totally ignorant in this matter. Why so much milk?
how about using @geyser ?
lmao nooo ahahahha.
It was a disagreement about the distribution induced by an hash function is continuous or uniform
I mostly get what you are saying, just hard to follow the details because I haven't studied PID in a rigorous way.
Anyway, it's interesting to wonder how many times the bell curve meme is right 🤣
One think about the simple solution first (satoshi's difficulty adjustment), then he learns that there are more sophisticated mechanisms, then after a deep dive he recognise that the first solution is good enough as the more sophisticated mechanisms give you some benefits but nothing essential.
Interesting!
Yeah, thermostats can be very stupid and still work, and so does Bitcoin.
overshooting and undershooting a bit is not such a big deal.
What's important is to have a mechanism that eventually will reach the target.
Sometimes I think about concensus parameters, and wonder that one can change them but not by much.
10 min blocktime could have been 5 min, or 20 min, but not much more different.
1 MB is now up to 4 MB.
The thing that cannot be changed is the difficulty adjusted Proof of Work. To me that's like a new primitive, a new concept, like the circle. One cannot improve on the circle, you can only discover it.
Again, I wouldn't say "validating transactions".
Nodes validate transactions.
Mining:
1. offer an anti-spam protection service
2. creates a way to choose which one is the block to be considered valid without relying on any third party.
I watched the whole video on yt
That animation was amazing!
Also, the one with complex numbers is really good
But, for every block, the difficulty is set, so what the miners do is playing the roulette.
The roulette changes, the game is always the same, and it's not complex.
