High-security seed generation

Coin flips

Rule 0: tails is 0.
Rule 1: heads is 1.

With or without following these rules, you can write down binary code generated by the results of your coin flips with one or more coins.

You'll need a total of 128 coin flips for a 12-word seed, or 256 coin flips for a 24-word seed. Writing in rows 11 digits at a time will help with the next step (11 or 23 full rows, then a partly empty row of leftover digits).

The reason it takes so many coin flips is because your goal is to make it so nobody can ever get the exact same sequence of coin flips you got, even by having a computer try sequences a million times a second. Even a computer trying a million times a second takes too long to find every possible 128-answer-long sequence of "yes/no" answers. For a 256-answer-long sequence, forget about it. Nobody will ever have the same sequence as you unless they copy it from yours. This just doesn't work if the answers follow a pattern instead of being random, that's why you have to flip coins.
