Impossibility of Brute-Force or Listing:

[rosebaby3892]

Here's why such a database is impossible:

Private Keys are Simply Numbers (and There Are an Astronomical Number of Them):

A Bitcoin private key is nothing more than google voice database a very large, randomly generated 256-bit number.
The total number of possible private keys is 2
256
To put this into perspective, this number is approximately 1.15×10
77

This number is far, far greater than the estimated number of atoms in the observable universe (10
80

It's also vastly larger than the number of grains of sand on all the beaches on Earth.


Because the number of possible private keys is so astronomically large, it's computationally impossible for anyone to generate, store, or "brute-force" (guess) all of them.
Even if all the computers on Earth were to endlessly generate and check private keys, it would take an unfathomably long time—billions of times the age of the universe—to even scratch the surface of the possible key space.
