Added DLC support for Musig2 on development branch.
Now you can tweak the group nonce with an adapter key, then later tweak the group signature with the secret.

This DLC scheme should also work with FROST.

Had the pleasure of being a "whale" this year at BTC24.
The wine and dine experience was nice, and there was a bunch of celebrities plus high net worth folks walking around.
We had a live feed of the main stage, so you could watch speakers from the comfort of the deep.
The room was packed when RFK was speaking on the main stage, with clapping and cheering at certain points in his speech.
When RFK made the point that Bitcoin is about more than just "number go up", the room was dead silent.
Just thought that was interesting.

I appreciate Elon reversing the globo-homo trend to censor everything on twitter.
But the content feeds are no longer the same. I don't feel in control of my own feed.
I think AI is dead-end for curating content. I *want* a dumb algorithm that I can wrap my head around. I don't want a black-box neural network that I can only make polite suggestions to.
Humans like game loops, you don't have to hide them. Just give us the controls and let us run the loops the way that we want.
Game companies know this. They give users what they want. Yet social media companies are taking these controls away?
Maybe because on social media, you are a product, not a user.
Nostr is in a great place where the users have control over their own loops. And developers are free to design new loops for us to try out and better control our content feeds.
Legacy social media is for the bots and the birds.

I agree with this on cash deposits but I don't understand how you would run a real credit system with anonymous transactions and accounts.
How would you measure credit risk? How are charge-backs supposed to work?
There are reasons that credit card holders would prefer transparency and buyer protection over privacy.

In a few days, I'll be making the case that the nostr relay network is a distributed consensus system for the delivery and receipt of cryptographic messages.
I believe this consensus system may be far more valuable than the social-media use case.
It solves a few important problems in cryptography protocols, and is far more efficient than publishing data to the blockchain.

Yo @nprofile…w0my how do I pump my trust score up? I gotta get rid of these rookie numbers.

I may have inadvertently created an anonymous e2e encrypted coin mixing protocol that runs over nostr.
