~22 hours until signaling BIP110 becomes mandatory for Bitcoin miners. Mining blocks without signaling will then forfeit all block rewards!

“Signaling” cannot be mandatory

Why would attackers wait the address to transact instead of directly stealing utxos?

The attack began as 6-7 figure sweeps, then moved down to 5-6 figure sweeps; my assumption is they are prioritizing big bags first for max extraction. 🤷‍♂️ If you order the attack solely by whale → shrimp UTXOs, then all the small fries have time to scurry while you're spending compute t...

If NVK knew of the vulnerability how would coldkite go about fixing it without exposing to the public the flaw. It’s possible their hope was over time people would migrate their funds to new wallet...

Migration to new wallets doesn’t guarantee people will create new seeds, unfortunately

Yes, that's one. It is possible to produce an incomplete list of ways to screw up dice rolls, but it is impossible to produce a complete list of why humans screw up dice rolls.

H 1785850824

How logical it is not to start a list at all because you can’t make a full list of something

mike · 5d

That's an impossible question to answer, because you don't know how long the list you didn't write would have been 😂

Agreed, what would you suggest to be a better label for it? coldcard fuckup? https://blossom.primal.net/1b183464433bf0b666dae7c22a6ea828aa735d29406834fe37bd19eb7ab69b3e.png

I remember the episonde of rhr. This was about only using dice rolls. Not about adding dice rolls. They recommended the adding of dice rolls. They warned about only using dice rolls because most peopl...

Adding dice rolls to a seed or using only dice rolls to create a seed is not that different in terms of difficulty. It simply requires more dice rolls than the mixed option.

256 bit entropy is a marketing gimmick in a long enough timeline all bitcoin narratives are scams

H 1785666441

So how much entropy do you recommend

more atoms than the universe

H 1785588009

I’m kind of reluctant to flash the new firmware immediately. I think ~160 dice rolls would be sufficient to create a new secure seed (Ian Coleman’s website calculates one dice roll = average of1.67 bits of entropy).

Perhaps. We know that dice rolls are fine. Do those and add a passphrase and you'll be fine.

Theo Hague · 1w

Is 100 dice rolls + Mk3 affected?
