A friend put his coldcard bitcoin on @strike . This is a smart move until you put together and test your new cold storage system.

Has anyone other than me thought of reverse compiling cohnkite's bootloader and reverse engineering it with AI to see if there are any more backdoors built into this thing? IIRC, the bootloader was closed source. I assume it's not fused out of allowing someone to read it out of ROM? View quoted note →

This is deeper than you think. When you're doing it right, demons will animate hateful people from blocks away to attack you. They don't hate you, they hate Christ in you. View quoted note →

Bits_of_entropy * log(2) / log(6) = dice_rolls

If you have more than 0.1 BTC, I strongly recommend generating new keys with a large amount of entropy and move to multisig stamped in steel and geographically distributed seed phrases. Why 0.1 BTC? Because if you have that much in self-custody, chances are that you are serious and need a good, secure and inconvenient place to stash your HODL stack. My only warning is to be sure to keep a cleartext and QR code copy of the wallet descriptor and ALL of the corresponding xpubs AT EACH of the geographically distributed locations in addition to whatever properly secured machine you use to monitor your wallet and perform transactions. If you do not have access to ONE of the keys, you cannot perform a transaction without the wallet descriptor and a copy of all of the xpubs for the multisig wallet.
