I just re-read Neil Chilson’s “simplified rewrite” of F. A. Hayek’s Nobel speech “The Pretence of Knowledge”. neilchilson.medium.com/a-simplified...

I had to remove "meta acquires moltbook" from my dead internet theory black mirror episode script because the other writers agreed it was a little too on the nose

Whenever you see news about Signal users being attacked, think of it as further evidence that Signal is the most secure and the most important comms app, and its users are being targeted by the most sophisticated attackers. Read this thread from the Signal twitter account: x.com/signalapp/st...

I saw this when I woke up this morning, and I thought about it all day and I posted this thread to twitter last night just before falling asleep. bsky.app/profile/zook... I think this is a strong signal. And a signal beyond just the “crypto industry”. ⤵️

Very good research. Finding and fixing important vulns in Signal (!), and also trying to learn how we as security engineers can prevent vulns like these going forward. Way to go, Truong, Terzo, and Paterson, and good on Signal for quickly fixing. eprint.iacr.org/2026/484.pdf

Happy Cypherpunk Manifesto day to those that celebrate! www.activism.net/cypherpunk/m...

Big news! The former Electric Coin Co team (now in a new company named “ZODL”) has raised $25m from a good group of investors to advance privacy as a principle and Zcash specifically! zodl.com/zodl-raises-...

So Pi AI sessions are self-contained and append-only. If we hash-address PI session data we get a personal AI with... ✓ Credible exit for model provider ✓ Credible exit for your context ✓ Decentralizable memory

Time is meaningless when you've been asked too often to put something aside for the Time Being. Everything now belongs to the Time Being.

Iroh blobs uses the exact same construction that BLAKE3/bao uses. Files hashed with iroh-blobs give you BLAKE3 hashes. We store the inner tree hashes only up to 16KiB chunks and recalculate the rest on the fly, but other than that it's identical to bao.

holy shit blake3 is fast as fuck

Are you aware of uses of the BLAKE3 secure hash function? Please contribute to this list! bfswa.substack.com/p/where-is-b... My hope is that lots of different tools all using the same secure hash function can result in “accidental” opportunity to protect and empower users.

When I was 6 years old, in 1979, my dad brought home a computer that he was building at his employer, Texas Instruments. Little 6-year-old me immediately fell in love with it. It was magic. Unlimited possibilities. It made me into a wizard. I never got over that feeling.

I love moving walkways.

principled actors can coordinate acausally, while actors that merely align based on loyalty must negotiate

Y'all got your hands on one of them shiny new Apple Silicon M5's yet? Please run this script: github.com/zooko/bench-.... It should produce output like this: github.com/zooko/bench-.... Post your results!

I can never remember where I left my reading glasses or my car keys, but someone just mentioned “To Kill a Mockingbird” to me and I somehow knew exactly where it was in my Wall of Books.

It's pretty cool that Jeff Dean independently came up with this same rough rule-of-thumb of 10X that Brian and I did. :-)

Huh! Interesting idea from @JeffDean: design your system to scale by 5–10X but not more. This reminds me that Brian Warner and I came up with the rule of thumb that once your system scales 10X then you'll hit an unknown-unknown: something will break that you hadn't thought of. x.com/olshansky/st...

Shielded Labs's position: strengthening Zcash's long-term sustainability and capture-resistance is *urgent*, because we have an opportunity to attract long-term investors *now*, and long-term investors are attracted by certainty and sustainability. forum.zcashcommunity.com/t/proposed-n...

& using same double-speak as NSA used, Trump's Pentagon would likely testify to Congress & public, under oath, that private comms of US citizens not "collected" - even if intercepted, decoded, stored, read by AI, & subset forwarded to human analysts - based on a peculiar deceptive def of "collected"

Is it weird to say that coding with agents feels more...organic? It feels more like tending a garden than building a house. You plant seeds (write specs), water them (poke it along), pull weeds (refactor messes). It's a different skillset but very informed by existing knowledge.

For some reason I hate the word "futarchy". (It means: you're going to be governed by the future!?) So I'm going to call them "Decision Markets". But anyway, this blog post does a good job of explaining the rationale and walking through an example: www.umbraresearch.xyz/writings/fut... HT Sacha

okay i have one problem with co-writing Javascript with Claude: i have a strict policy against using floating-point anywhere that it isn't absolutely necessary, and Javascript in both language and culture encourages floating-point everywhere *shakes fist at Brendan*

Thank you to everyone who participated in the NU7 sentiment polling! 🙌 The results reveal strong consensus on some proposals and real disagreement on others. Here's our perspective on where we go from here. zfnd.org/nu7-polling-...

Most Zcashers—people who use, study, hold, and love Zcash—don't have time to track technical proposals and governance processes, much less social drama. My main recommendation for them continues to be "read everything Jason posts". Here's his latest: forum.zcashcommunity.com/t/shielded-l...

As foretold, hacker/AI dyads are now creating new programming languages. campedersen.com/loon I expect this trend to accelerate indefinitely. :-)

I am not a "crypto maximalist" but I continue to watch the tech which is executed by people with actual principles, that have consistently delivered on goals, with long term interest.

Huh! Super interesting idea to create a "flatcoin" (a semi-stablish but not fiat-pegged token) as a native ("enshrined") function of Zcash: forum.zcashcommunity.com/t/zai-shield... I have thoughts. 🤔

For well over 20 years I've been taking 30 second videos of calm places & moments I've enjoyed being in. Today I figured out how to stream them 24/7 on stream.place, in a random order, in case anyone else might enjoy a moment of this little art project of mine. stream.place/byjp.me
