Do you use the term "self-sovereign"—for identity, for keys, for your wallet? If you do, it was ten years ago today I chose this term, using it to describe an inalienable right to control your own digital life. We've learned much in the last decade, so I'm offering an update.🧵…

I'm always seeking out the right words for what digital systems do to people. "Privacy" means something different in every room, and has become so overloaded it has become meaningless. "Censorship resistance" sounds like it's only about speech or money. Neither names the mechanism. 🧵…

👍 The new Utah #SEDI draft SB0275 has the essence of my first #SSI principle that I wrote 10 years ago: "(1) An individual possesses an individual identity innate to the individual's existence and independent of the state, which identity is fundamental and inalienable." le.utah.gov/~2026/bills/...

As a co-author & editor of TLS 1.0, I’m quite disappointed that the IETF editors & SEC Area Director have declared “rough consensus” exists to standardize PQ-only cyphersuites (rather than double encryption EC/PQ). Feels like IETF has been captured. See: blog.cr.yp.to/20251004-wea...

I just saw “The Majestic” on the big screen last night. When it came out it was 2001 and just felt like a nostalgic feel-good movie. But in 2025 its portrayal of resistance to government “red scare” tactics had the audience gasping with connection to Kimmel. More relevant today!

Building networks on cooperation & equal participation demands authentic ecosystem leadership & aligned incentives focused on real-world impact, not personal gain. But true ecosystem leadership is rare. Many network leaders today advocate for extreme collaboration but use it to push their agendas.

I actually am a strong disagree on "trustless" and "zero trust" There is no such thing as trustlessness or zero trust Instead there is such thing as *building trust* and *consent* in a hostile world We can't live without being able to cooperate and bulid trust. I believe in "secure cooperation".
