It seems that I need to learn more about some notions of algorithms and about the ECDLP signature system.
Thank you for explaining in detail.
-snip- A sufficiently powerful quantum computer (again, decades away) could easily break the ECDLP.
If in a few decades, a powerful enough quantum computer can break ECDLP, it will be a technological advance, but on the other hand, it will be quite crucial, because it doesn't take long to break or crack the ECDLP signature system.
what makes you confident in remembering the secret place where you stored your keys?
If I forget, I'll ask my wife. And as I said above, I can at least look for a physical back up in places I am likely to store one. If you forget your seed phrase, then you are shit outta luck.
In the end, we must have a trusted person to remind us of a secret we once made.
Maybe it's like a legacy that our children and grandchildren will remember.
Like a Treasure that has some clues to find it.
But it becomes an old technology that has many mysteries to be solved, but in modern times like this the way it is done will certainly be different.
There are many secret places that can be used to store anything and they can only be accessed by the owner and the rightful heir.
Any pleasant past events or any events that are memorable will be easy to remember, but not with complicated codes or random numbers, it is very difficult for anyone when it has entered the years.
