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.

post: 1vgw23z author: blackjackn created_utc: 1785996954 title: New Wallet After Coldcard Hack body: I was affected by the Coldcard hack. Thankfully, my Coldcard Q was only 1 key in a 2 of 3 multisig. My coins are safe. But with 1 key compromised, I decided to migrate. My new 2 of 3 multisig: \-Coldcard Q updated with the new firmware. Seed generated with 150 physical dice rolls using casino grade dice. This is one key. Yeah, I'm pissed at Coldcard too. Idk if the entropy issues are resolved through the firmware update. Thats what the community seems to say. I dont trust it. But I think seeds generated through physical dice rolls are fine especially with a strong passphrase and I like the hardware. Will never buy another Coldcard though. Not supporting that company with my money any further. \-Other two keys have the same seed as before generated using device rng (not Coldcard). All keys (including Coldcard) are now passphrased with the same 6 word passphrase formed using physical dice rolls and EFF list. -Going to have 2 separate people I trust each custody 1 key (device + seedplate), no passphrase. -Another 2 separate people I trust will keep backups of the uniform passphrase in case I forget + fire or theft (hand written on an piece of paper and sealed in an envelope). -Only I will have the output descriptor. Yes, I could have done a different passphrase for all 3 keys. Too bothersome and I thought it would be excessive. I accept this weakness. Not perfect but I figure itll be good enough. Posting as an example on how to multisig as I'm a proponent of it but by no means claiming this as the model example. Edit: Changes parts on how the keys and passphrases will custodied. Rethinking that. comment: p20chqv parent: t3_1vgw23z author: [deleted] created_utc: 1785997456 edited: false body: [deleted] comment: p20euaj parent: t3_1vgw23z author: Upstairs_Raisin created_utc: 1785998568 edited: false body: What’s the logic behind passphrase custodians when even with one key, one seed plate, and the heck-even the passphrase they still only have one signer?
