A Stacker News thread linking a YouTube video (youtu.be/oj_W3xOlt6U) said to show the BTCRecover maintainer warning about COLDCARD entropy two years before the incident, and claiming NVK had blocked him on X. The prior-warning claim and the block claim are the thread author's; neither is verified here, and the video itself is not captured by this archive.

Captured through the site's public GraphQL API: the browser route crashes the capture tab on stacker.news pages, and the API answers POST from this host while the rendered page is challenge-gated. The query fixes the captured surface to the item's title, text and two levels of comments, each with author and absolute timestamp.

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 15 Aug 2026, 12:26 UTC.

capture correction difference between 4 Aug 2026, 00:16 UTC and 4 Aug 2026, 00:35 UTC Current capture correction +44 -20

The capture route moved from the crashing browser tab to the stacker.news GraphQL API. The preceding snapshot (20260804T001640Z), written by a scheduled poll that overlapped maintenance with the old configuration, held the MARA Slipstream portal text read from a stale tab after the stacker.news tab crashed, not the thread. This capture is the thread's first real content, and a tab-identity check now refuses to file a page whose host does not match the source.

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.
