Essentially, the biases I measured would result in a much lower loss of entropy than I initially thought because they are obviously non-deterministic, which means everything is more secure than I initially thought.<br/><br/>That being said, coins/dices can have significantly higher biases than you assume &amp; I invite you to verify this by yourself (since ultimately, you can always default to doubting whatever I will say on Nostr). Try to compare good nice heavy coins with light ones or various shuffling method &amp; you&#39;ll definitely find out that the theory is not meeting the practice.<br/><br/>On the other hand, the wash shuffle is an excellent randomizer is used in casinos all around the world. So when it comes to ranking our options, I am pretty sure tiles would come first in any proper study. 2026-08-26T03:40:54Z https://nostr.now/nevent1qqs8hashq86zle66qfarmnqknvjldhw97h9gfqwds3j273lupeanusczyqm7l00d00weaj87jl84xfxkewgr4jup6we6kjnz07t9ddhhvvgwxtyjywe In reply to <a href='/nevent1qqszf8qr4pxkkacr2f6c869scwdvpm8jr2gd449wshn59zwrql40wtqygkhtl'>nevent1q…khtl</a><br/>_________________________<br/><br/>I call bias the net loss of entropy, which is what we care about, and not the deviation from the mean. In that sense, 51/49 is already a 2% bias, out of a big fat coin that&#39;s nothing like what you have in your pocket.<br/><br/>And no, it doesn&#39;t diminishes over turns: it&#39;s a whole 2% entropy loss on your final entropy: so you&#39;d get 125,44 bits of entropy instead of 128.<br/><br/>Now, to be clear, even a 20% bias would lead you to an unbreakable seed phrase -- so in that sense, maybe it can appear negligible. In any case, my goal with Penlock was to create a fail-proof process, and while my number are rough estimate I stand by paper tiles having the both a better safety and entropy profile. 2026-08-25T19:02:22Z https://nostr.now/nevent1qqsqqqz640rla9f5fq0v332kpemh497wtz3z35u3zftd0d8wqqh835qzyqm7l00d00weaj87jl84xfxkewgr4jup6we6kjnz07t9ddhhvvgwx2zzgmc <video controls width="100%" class="max-h-[90vh] bg-neutral-300 dark:bg-zinc-700"><source src="https://v.nostr.build/VTanqptzSEWw9ySxU0rIGo.mp4"></video><br/><br/>🔐 Learn how to create a seed phrase by hand in under 10 minutes!
