Current Question

August 12, 2026 0

So we see alot of discussion currently around multisig, passphrases etc. what wallet is save bla.

What no one mentioned yet is shamir backup with trezor. So you could make a 2/3 situation where 1 key is online and 2 keys are on different places. A friend or family member or your bank place. And i saw that you also can add a passphares like a bitbox.

Wouldnt this be secure and save against like most szenarios?

Maybe im blind or dont get it but for me this sounds very practical and not that hard to understand. Maybe some pros can give me a answer or so 😬😬 thanks

A Question About Diceware Passphrase Entropy

August 11, 2026 0

My friend has a coldcard and is in the process of moving funds to a new seed. When they generated a passphrase for this new wallet, they used only 4 words of a diceware list, and transferred some funds to it. Only afterwards did they find out that they really should have used 6 words. Since the 4-word wallet has a transaction history, would reusing any/most of those 4 words in the new 6-word wallet reduce entropy for a brute-force attack? (i.e. since the hacking algorithm would find the 4-word wallet quickly, would it then be more likely to search for 5+ word wallets containing those original 4 words?)
