Informational only. This is an open source collection of what others have published about the incident, together with an explanation of it. It is not financial, security or legal advice, and not a substitute for professional advice about your own situation. It is not affiliated with, endorsed by, or speaking for Coinkite. Material is attributed and quoted as published; where sources disagree their scenarios are kept separate with their assumptions rather than reconciled into one answer. Everything is meant to be checked against the linked evidence rather than taken on trust. Act on your own judgement about a particular situation. Editorial standards and corrections.

Do not disclose recovery material to a website, form, message or support account. This site never asks for it, and contributions containing recovery words or private keys are not accepted.

Community proposal (Silexperience210, 3 Aug 2026) arguing the 31 July hotfix leaves the STM32 RNG latched after a single seed/clock error, so every later call faults forever; proposed a recovery path. Closed unmerged. Related to the post-hotfix bricking reports.

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 .

1 presentation-noise difference. Sidebar, ticker and other page chrome churn that our review classified as not being a change to what the source says.
  • +5 -3 Only GitHub header chrome changed. The 'Sign in' and 'Appearance settings' labels split onto separate lines, and the search prompt changed from 'Type / to search' to 'Search/'.
How to check this yourself

The excerpts and plain unified diffs above show the text this project held and how it changed. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.

Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
