My two cents.....I had an unopened MK4 that I wasn't using when this all went down. I updated the firmware and I created a seed phrase with 100 dice rolls. I did a test set of rolls first to see if the CC provided the same value for the rolls as on bitcoiner.guide/seed/, it did. I then created a new seed the same way (without checking online) and added a passphrase.

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.

So you compare that the seed you got from mk4 after entering 100+ rolls is the same this script gives you after entering the same 100+ rolls in a secure environment (this is the part i'm not fully remembering yet).

edited: false body: Same. I did 50 live dice rolls when I setup my CCQ. Then a strong passphrase as well. Then I have multiple wallets both single and multisig under that also using bip-85 so I think im safe, but I still feel like I should move everything to a new seed. It’s a lot though, so I don’t really want to. + +comment: p1pwfvl +parent: t3_1vc55eb +author: thelaurelhighlander +created_utc: 1785874185 +edited: false +body: +My two cents.....I had an unopened MK4 that I wasn't using when this all went down.
