I am starting to like my own nostr client :-)

flink — a fast nostr client

Flink — a fast, minimal Nostr web client.

I am seedsigner user and also advertise them. But now i am asking myself? What kind of entropy you really got if you just take a picture with the cam? (for randomness, no dice rolls) I didnt calculate this yet myself. But it could be its not true 256 bit entropy? I am just asking.

I wonder why the mempool is not filling up? Did so few people own a coldcard?

With all whats going on. This is a real mess. I own over one dozen hardware wallets. I got my favorites, which is air gapped. But i myself knew about the RNG problem in general. You have to use physical randomness to generate your words. Most hardware wallet sellers solved it with some kind of combination of data or even white noise sensors. Which sounds promising. But did i check the software/firmware if the process got disabled, no i did not. The only way that solves this is to roll the dice in the future. I try to figure out 8 face dices of which you only need 4 to roll one word, which you can look up in the words table. Then calculate the twelve or 24th word. So you are not dependent on a software RNG at all. I need to roll the dice too because i cant trust any software or silicon to generate a random seed.

So i also like to give my 2 sats to the conversation regarding entropy bugs. Every bitcoin onchain wallet software and all of its versions can still have a bug. The problem with random numbers is, you cant prove the entropy of a seedphrase after you generated it. Coldcard firmware was 5 years old and 1 year old AI models could have found this bug. So the real question is, was your seed phrase generation done with enough entropie? You only know for sure when you roll the dice.
