Index of third-party reporting and research on the incident, each entry linked out to its source. The site is an aggregator run alongside promotion of competing open-source hardware (SeedSigner, BTClock, Passport) and takes an openly critical stance toward NVK and Coinkite, so its selection and summaries are editorial and interested; the operator is not named on the site. Tracked for what it chooses to include and when, and as a discovery feed: anything it surfaces is followed to the primary and registered there, never cited from this copy. SPA with no feed or API; every path serves the app shell, so capture goes through the browser.
Every check is recorded, including checks that found no text change. A detected edit is therefore bounded between two checks. The publisher's exact save time is not observable from this record. Last checked .
This post is held twice: here, with this project's own note on why it matters, and again as part of the conversation captured at , which is polled for changes. Both copies are the same post; neither is a separate event.
Snapshot and diff bodies for this chain monitor are held in the local evidence archive but withheld from the public site because they can contain the addresses of people who published nothing themselves. Capture times and reviewed change summaries remain available below.

(opens in a new tab) X · Zach Herbert · 3 Aug 2026 A long, densely linked rebuttal by the cofounder and CEO of Foundation Devices, one of the companies it says NVK attacked. It gathers years of quotes — each linked to the podcast, post or commit it came from — on the treatment of Passport and SeedSigner, the handling of security disclosures, and the GPL and trademark disputes. An interested party, and it says so, closing: "Do not trust NVK. Do not trust me either. Verify."
