Today, I am releasing my first formal research paper: Credible Exit and The Law of Conservation of Blockspace. It shows the limit on users that Bitcoin layers can support in a "trust-minimized" way, and proves layers cannot actually scale Bitcoin. Blockspace.science

My favorite features of Pubky are the ones we are about to ship: 1. Collections - We redefined the concepts of bookmarks, blogs, channels, albums, pin boards, podcasts and all types of sets or series by elegantly combined them into one primitive concept for the network: collections. Coming VERY soon. 2. Locks - "Unlock" any content using any mutual payment method. This brings both ecommerce and a new level of payment coordination to the free web. 3. Graph Views - If you think social graphs or web-of-trust is cool, wait til you see our customizable graph visualizer and start filtering the web, and your peers, with it. These are not merely cool new features for Pubky App. These are some of the most powerful primitives the open web has ever seen, and the features we demonstrate only scratch the surface of what's possible. ...And these are just a portion of the projects we are working on in our effort to provide the Atomic Economy to humanity. We know what to do, and we'll keep building it out until it is crystal-clear why you should join the next web.

The Bitcoin scene is dead, but it will be reborn better than before.

Very appreciative of the @FoundationHQ team and their independent effort to support Pubky technology. Thank you so much. We are working hard to bring new freedom tools that will eventually unlock a new economy for everyone.

I guess we need a new list for the 2026 bear market... Clearly something needs to change with paper bitcoin. My guess is, somewhere near the bottom-price, the government will add some sort of friction to paper bitcoin products, causing one final panic. We need Bitcoin securities to be boring.

Game theory means absolutely nothing in Bitcoin. All sides of all issues claim it. Not one of them offers a proof or even a valid model. Muh game theory, that's why.

Bitcoin is only special in that it is the most censorship-resistant and secure scoring method. If people aren't using it for its security, and thus, black-market-money capability, they are just speculating that other people will value that security and censorship resistance. "Credit" is interesting in its own way, but Bitcoin doesn't affect the credit layer of the economy, it just offers one more collateral option, among many other acceptable settlement options. Bitcoin being the "one true blockchain" or "scarce" is not enough to make it valuable. People have to actually need that security and censorship-resistance. Otherwise, any blockchain or asset, or even pure credit, would be good enough.

Interested in how Pubky app actually works under the hood? The Pubky App specs define the data models and validation rules for compatible clients, from users and posts to tags, bookmarks, follows, and feeds. Build with the same rules: github.com/pubky/pubky-ap…

This is admitting the model leaks capital into reserves, yield payments, and financial engineering, so Strategy is building an official valve to bleed real bitcoin when the paper obligations get expensive. The same company that spent years pushing the “never sell Bitcoin” story is now codifying the conditions under which they will sell it. Classic paper: the underlying asset ends up subsidizing the claims written on top of it. Stop falling for this bullshit.

💡Pubky Mint is another community-built project to "browse the Pubky ecosystem in a refreshing way". It gives you a clean, RSS-like view of the people you follow, so you can explore their activity without getting pulled into the usual attention traps. Check it out: github.com/ok300/pubky-mi…

Try to have an angle on it if you do. Interviewing the most famous bitcoiners and their friends has been done so much already. Personally, I just want to see people being real and sharing their experiences and challenges. I am tired of hearing the ignorant opinions and predictions of scammers and influencers. It is always the same topics, same questions, same investor cope...

i could do a bitcoin podcast. something i keep coming back to. i'm confident i could do it very well and eventually fit into your regular listening. but... just coz i can, doesn't mean i should. should i?

If you are still interested in Bitcoin Knots and BIP-110 please respond to this post.
