Does anyone else find it weird that the Bitcoin security expert who spotted and executed the coldcard hack reused addresses so heavily?

Check label, 50lbs. Carry it up the stairs. What the hell kind of pounds were those? Check label again. The kind of lbs that are kgs. That explains it.

It wasn't just a policy change that wasn't communicated. I checked the dates against my orders and this is definitely a lie at the time he made this post. View quoted note →

Today I'm wondering if the outcome is that AI destroys the tech industry and forces us to abandon connected devices altogether. Why would I want my new thing to be connected or even electric at all if avoidable? Around 10-15 years ago I was obsessed with the idea of connecting all the things. Now I don't want it anymore when that future finally arrived. Will it take another 10-15 years for wider society to catch up to my thinking again or will I diverge forever and just become more weird?

This weekend I saw a huge number of people dropped everything and spent days helping others. Yes bad things happened, but if you aren't inspired by that level of community caring for others you are dead inside. As long as that spirit remains Bitcoin will survive just fine.

This is a start. I won't even consider forgiving or forgetting until I see projects like seedsigner where NVK blocked funding for competitors get funded. View quoted note →

Today's adventure in chores you should have learned about in adulting class but didn't because adulting class isn't a real thing even though it should be. I cleaned out the dryer vent, all the way from the lint trap to outside the wall. I know that usually isn't far but in my house it is kinda far and involves a booster fan because my house is dumb.

Some math on how possible various coldcard attacks are. There may be shortcuts I overlooked. Mk3: 40 bits aka 1.1x10¹². This space can be precomputed on a single GPU in around 2 weeks and a complete table of xpubs + seeds is storable in under 100 TB. Using that stored table grinding 2 of 3 wallets using all mk3 seeds is computationally possible today with the same quality hardware the attacker already showed they have access to. Any single key not from a mk3 means an address out of the lookup table breaking the brute force and lookup table attack. Mk4: 72 bits aka 4.72x10²¹. Brute forcing this entire space is not computationally doable today but may become possible with better hardware. If you can't store the table of xpubs grinding multisig wallets is also not reasonable. Simple 2 of 3 multisig would require compute the entire time across a space of 216 bits aka a 10⁶⁵ scale in decimal. This is back into Landauer limit space. Perfectly efficient computation requires the entire energy of the sun for over 200 million years. True random bip39 24 words for comparison: 256 bits aka 1.16x10⁷⁷. The 2 of 3 multisig space is 768 bits aka 1.56x10²³¹

Checking my emails closer. An early order got a "your data is about to be deleted notification email, maybe true maybe not. I made a later order, but years ago and far longer than the window mentioned in the first email saying my data would be deleted. The second order never got a deletion notice. View quoted note →

I got the coinkite email. Alias email used and my last order was before the Q was released.

Anyone heard a peep from opensats? Some of us have been pointing out the conflict of interest for ages and now this. Will they boot him or kill their remaining good will in the community bu standing by NVK or pretending nothing happened?
