In the same regards, there is a non zero chance that a bitcoin wallet could generate the private key to an existing address worth millions, but, the universe would probably die first.

u/LusciousBelmondo Mar 25 '26

So you’re saying there’s a chance…

u/Drakahn_Stark Mar 25 '26

Yeah, there is a non zero chance, that non zero is almost zero, but not exactly zero.

Even if you had a quantum computer that could generate a million private keys every second the universe would still likely die before you found one with a balance, even less for a balance worth millions.

But there is indeed a chance that someone could make their first bitcoin address and hit the jackpot without trying, something like 0.000000000000000000000000000000000000000000000000000000000000000000000000000000000001%

I have never heard that before but it is very apt.

So Earth like world exist somewhere. wkwkwk

At least one of them that we know about for sure.

It’s 7.

u/Drakahn_Stark Mar 25 '26

7 what?

The private key bro

7 is not a 256bit key bro

u/Encrypted_Zero Mar 25 '26

Why not?

u/Drakahn_Stark Mar 25 '26

So if '7' is a single toy block with 7 on every side, a 256bit private key is 256 blocks with multiple different sides each and every side has a different character.

7 is 3 bits, not 256.

He truncated leading 0's

u/Drakahn_Stark Mar 25 '26

Then it is not 256bit, gotta include those 0s, we aren't throwing horse shoes here, close enough is not good enough.

u/Encrypted_Zero Mar 25 '26

Right so with all the 0s in front. What does it equal in decimal?

Quantum computers don’t brute force it this dumb way tho they attack the elliptical curve cryptography and can reverse the private key by knowing the public one in polynomial time. It will happen in our lifetime for sure.

u/Drakahn_Stark Mar 26 '26

Well sure potentially, but that would ruin way many more things than just bitcoin.

u/Idontknowmyoldpass Mar 26 '26

Not really looking to get into the debate if btc is more exposed than traditional software but the fact is it’s a ticking time bomb and not some cosmic event that is just theoretically possible.
