Update 2026-04-15: The previous version of this post mistakenly conflated two proposals in one of the section titles, so now there is a new anti-roadmap item, Disabling creation of QV outputs , and another anti-roadmap item was renamed from Forced migration to PQ addresses via zkPKS' to Recovery of QV coins via zkPKS' . I also added Continue reading "Responding to the quantum threat to bitcoin"
MP3: Q A session with Rusty Russell and Julian Moik, co-authors of the Great Script Restoration BIPs. The recording started a few minutes into the session so some of the beginning of the call was cut off. Audio from my mic was also not captured very well so I re-recorded my questions and spliced them in. Continue reading "Great Script Restoration Project Q A October 15, 2025"
Update 2025-10-08: This post was originally written as a response to a video published by Jimmy Song. The post has since been lightly edited to generalize it for a broader audience.

Today is the 15th Genesis Block Day, the anniversary of the creation of bitcoin s genesis block.

Every Genesis Block Day, Bitcoiners can participate in the Proof of Keys Continue reading "Not your keys, not your coins"
Update 2023-12-15: In the feature comparison chart, I replaced Can onboard directly to the protocol with Trust-minimized zero-conf onboarding , to better convey the difference between Lightning and validity rollups/validia chains that I wanted to highlight. Thanks to roasbeef for asking questions that led to this update. I also added Can send payments to an offline Continue reading "Comparing the…
RE: https://nostr.band/note12yse7ke6t6wcx79h2rzmwzqj2mmqyze3evdg0k2aa0xkkx79jtassf063z I appreciate feedback on the proposal, but there is a lot in this note that I think is just flat out not true. Given Preston s large audience I felt compelled to set the record straight. There s also more speculative or opinionated statements I disagree with and provide an alternative perspective on.

This post is based on two Twitter threads I published about sovereign rollups on bitcoin here and here. A few weeks ago Eric Wall gave a talk at StarkWare Sessions where he left the audience with an intriguing idea: what if we used the same technique that inscriptions use to embed data in bitcoin to Continue reading "Sovereign rollups on bitcoin"
Last last year I had the pleasure of attending The Atlanta Bitcoin Conference aka TABConf. While there I saw many old friends and met lots of interesting new people as well.
