Jameson Lopp lists earlier weak random-number-generation vulnerabilities found in wallets and libraries, including COLDCARD Mk2 through Mk5 and Q, to show the problem is not new. Held as historical context for the incident. The inventory is the poster's own compilation and is not independently verified here.
This post is registered as evidence and has a locally held capture. The original remains the canonical publication. 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.

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.
