Inflation in one picture

Euro: everything gets more expensive Bitcoin: everything gets cheaper I know what I'm choosing. submitted by /u/relaiapp [link] [comments]

There are a bunch of videos now on youtube, teaching how to generate a seed phrase using dice, but two of them were particularly interesting. I won’t post their channel names or link to their channels. But one of the guys was a bitcoin guru, offering...

Coldcard entropy even worse than feared

TL;DR: The random number generator is initialized with a 32 bit value (4B+ possibilities). But only less than 10M options are possible because of how they generate the value. The PRNG used in Coldcard MK3 is initialized with UID[31:0] XOR SysTick->...

The weirdest part of the Coldcard mess: was Peter D. Gray talking to himself through “switck”?

I’m not going to re-explain the RNG bug. That part has already been documented. What I want to know is who exactly was behind switck, and why this identity existed in the first place. Someone checked the actual Git signatures in the switck/libn...

That cold wallet with bad randomness, how did the bad actors know which addresses used it?

I'm reading about people losing their bitcoins because of a flaw with the wallet's random number generator. But how do the attackers/thieves know of all the UXTOs out there, which ones happen to have private keys that were generated with that...

Are people still DCA’ing to their hacked cold cards addresses automatically ?

I’m wondering if there are still people doing automatic weekly buys and transfers to their cold card addresses. I know places like River allow you to buy automatically and withdraw automatically at given thresholds. I haven’t seen this topic being d...

Coldcard seed flaw - flagged independently in 2024

Proof of negligence? I can’t see how it isn’t. This will definitely be included in the class action lawsuit against Coinkite. submitted by /u/Ace2021 [link] [comments]

Dust Attack

My hardware wallet does not have coin control. I now have a couple of unknown dust deposits. Do I need to be concerned and move to a wallet with coin control to isolate the dust? What can actually happen if I spend that dust. There are plenty of phis...

Were they acting in good faith?

Am i the only one who thinks that perhaps (i repeat, perhaps) the whole coldcard shitstorm happened in good faith? Could it have been "just" a huge, disastrous oversight caused by poor software development practices? I’m not here to excuse...

Coldcard CEO Rodolfo Novak confessing 2 moths ago in a podcast regarding AI audit bug reports: "Everything was like high like they said everything is like 'high high so it's like 'super dangerous"

First this part, he recognizing is lame for bitcoin products to blame AI... Interviewer: "...The BIsq announcement thread mentioned that it is likely an AI powered attack. So maybe people using you know is it some North Korean group using...

I reviewed how long Bitcoin took to recover after: 2013, 2017 and 2021.

The largest crypt heist, amounting to $3.5 billion, was caused by weak entropy 6 (!) years ago.

The infamous Lubian hack saw $3.5 billion siphoned off from a Chinese mining pool. That was just six years ago, and yet a company like ColdCard has learned nothing from the biggest heist in recent crypto history? The Technical Cause: Weak Entropy Ind...
