As much as I'm a proponent of vibecoding tools, they can't yet solve major problems creatively.
I lost a lot of sleep trying to work through these problems, and I wish Claude could have figured out the main ideas for me.
In this case, the problem was, how can an app show decoy watchlists/portfolios without revealing that it's a decoy, even to those who know that the app can show decoys?
I think we made significant progress.

darkfolio custodies no funds, but I wanted to build a portfolio tracker that would support rather than undermine decoy wallets. So I created Ghost Mode, a self-consistent plausible deniability system.
When activated, one PIN takes you to one space with watchlists/portfolios, and another PIN takes you to another space with different watchlists/portfolios.
Nothing in either space says "this is the real stuff" or "this is the decoy stuff." Users choose what they want to use each space for. And both have the same features, in and under the hood.
One crucial constraint, then: someone inspecting the app shouldn't be able to tell that someone is in the decoy, even if they *know* about the existence of ghost mode itself.
But I ran into an issue with Apple's purchase history.
The original set up would make Ghost Mode a paid feature and the decoy would appear, in the app, as under free tier, where Ghost Mode is locked.
Then, all free tier users would give paid users in the decoy plausible deniability. Is this person truly free tier, without ghost mode, or someone with ghost mode in use? You wouldn't be able to tell.
But I soon discovered that Apple's purchase history in iOS is permanently visible, and you can't do anything about it. So someone could quickly find the receipt and see that, although the app shows as free tier with ghost mode disabled, the user had an active subscription. Cover blown. Plausible deniability gone.
After a couple days of failing to come up with a solution, I feared that Apple had made the feature impossible. I was up late one night, trying to figure out another way. And then, at 3 AM, laying in bed, an extremely simple solution popped into my head. And it worked.
Now, even if someone knows about darkfolio, and that it enables decoys, they can't be sure the app is displaying a decoy without significant resources.

I built a verifiably private portfolio tracker.
Darkfolio is live on the App Store.

It would solve the currency problem but the problem remains one of distribution. We don’t have the time or capital to buy and store copies. And no one else wants to except the traditional venues that sell only for dollars.

Since our academic press won’t sell copies for bitcoin, we would need someone else to take on the middleman risk of buying, storing, and selling copies for Bitcoin. So it’s more a distribution problem than a Bitcoin problem.

Nostr has really grown since I last spent much time here.
Thrilled to see that some of you have hundreds of thousand of followers. 🎉

The drivechain argument that it will slay altcoins does not withstand scrutiny, imho.

I’m 80% through the episode and I thought Danny’s question about encryption being the main factor in securing data - not proof of work - was exactly the right question to ask. So far, lowery hasn’t said anything that would make me think he has a point that is both true and original.
When he says something that sounds new, it seems wholly confused, wrong. And when one of you challenge, he retreats into something true but uninteresting.
But I still have a few minutes left to listen.

Over the last 1.5 months, I’ve been with other bpi fellows on our manuscript workshop in Seattle, on a panel at Princeton University’s DeCenter, and at the BPI summit in DC.
I’m lucky to have spent so much time with bpi people recently!

I am basically fully on board with this. I do sometimes worry about existential risk - about nuclear holocaust and so on. But I do so because I want my descendants to have a good life. But I rarely worry about it. I’m very much with you otherwise. I’m hopeful about an afterlife. 🧡

2023-03-05 04:29:42 CET

How many seconds of my life have I worried about existential risk from AGI?
zero seconds.

I’m going to encourage my graduate students to download a lightning wallet so I can send them sats.
They need to “feel” how smooth lightning is, whether they think bitcoin is good or not.
Feel free to zap me some sats and I’ll forward every single sat on to them for educational purposes.

Biden was an enemy of privacy in the cryptography wars of the 1990s.
While he was VP, his administration oversaw the unconstitutional attack of dozens of fully legal kinds of business through Operation Chokepoint.
And now, his administration combines these past mistakes into a new one - a coordinated attack on businesses related to cryptographically-powered money.
Bitcoin will outlast these businesses. And then it will outlast Biden.
