Flashing screen with “verify” than blank screen with red light
So I wanted to deep dive on the old NONCE attack on hardware wallets, specifically whether the COLDCARD Mk4 leverages each of it's True Random Number Generators (TRNG) on both secure elements to generate random numbers and combine them using XOR.
Checking out this blog post... and HOLY SHIT, my respect for COLDCARD's security just skyrocketed. They don’t just use both secure elements but they also throw in the Microprocessor’s TRNG and XOR them together, with all of them chatting over a few millimeters of copper via encrypted comms. And that’s just scratching the surface!
No wonder nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 loses his mind when people use Raspberry Pis as hardware wallets.
This is the blog post:

It's worth a read if you want a wow moment 🙂
Can anyone help me troubleshoot a Coldcard?
Elon has gone down the rabbit hole. He’s now posting Milton Friedman.
#Bitcoin was designed for every human to take personal responsibility for preserving the value of their economizing time spent. The more humans that take personal responsibility, the more decentralized and the more secure the network becomes. Your Node, Your Miner, Your Wallet, Your Keys.

As the potential for war escalated, could the rising price of #bitcoin put a halt on war?
About Monday night. Were we in the presents of Satoshi 🧐. Always something hashing nostr:npub1key55ax33gkl50uqemvl4khrtqrhzm7wzpc7fhseutt5ddkcwcrqgxlt3h

Using Bitcoin as a medium of exchange only increases the value and imposes a free market economy.
80k, not a bad way to start the day. 😊 GM plebs.
Bitcoin eliminates the need for trust. Bitcoin will be blamed for enforcing verification.
Oh boy it’s going to be an exciting Brooklyn Bitcoin Meetup Tonight! Can’t wait! Where do we start.
Either #bitcoin is the answer or we don’t have one.

It's still crazy to me that today I used my nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 linked to my nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm Hub on my nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll to buy gas with a nostr:npub1m7r9aayrqjtt2q0whkyrwlys75s5d828c5uewvqwyfd2kxefkfjqgeny2w gift card from accumulated zaps.

Sound living
His last interview with Saifedean was a truth teller.
We need more plebs running full nodes and simple solo miners like #bitaxe. This will improve security and it’s just a matter of time before we get to a place where everyone has a wallet, a node, and a miner!!
Staying humble while stacking
