Hi Bjorn, remember this topic? You called it “brain wallet”. Sparrow took it to the next level to called “border wallet” it’s ideal for crossing dangerous borders.
As I had mentioned before, the major flaw with your original idea was the arrangement of the words on a grid. It needed to be scrambled with true entropy, but still be able to be recovered. This way, there is no need to save the pattern and risk having a computer program try to guess it.
Also, Sparrow added another layer of security by setting the pattern to be 11 or 23 words instead of the full 12 or 24. This requires you to memorize one extra word that is not part of the pattern, so cracking it with a computer would be extremely difficult.
The recovery words for the scrambled grid also functions as a decoy wallet that could be empty or have a small amount to disguise it even more.
Overall, it’s still very dangerous to rely on your memory. It’s good for emergencies…maybe have trusted family members memorize it as well and have them understand any clues to may have about your pattern.
Anyways, it’s kind of cool that something you thought of it got refined and created.
