This question is arising in my mind after i did some research. What will happen if someone brute Force Private keys in Base58 Format ?
And he succeeds then I think he will get admin access to all the wallets and can ruin the Bitcoin. I know it's very hard to go through the database but It's not impossible either.
Tell me what you guys think about this.

I think accessing private keys of all bitcoin address is quite impossible as to access private key of even one bitcoin address will take lots of computing power and very long time may be even a lifetime period. There is some fear regarding supercomputers and quantum computers which are still a dream and yet to find actual working prototype so i don't think this is possible and will be possible even for next decades.

That will not happen from night to day, we will see it coming with years or even decades in advance, things can be changed for when such event to occur.

I didn't meant for a single Address I meant he generate all the private keys which are possible and then search them using the addresses . Isn't that correct

it would not be wrong to say that a thing is impossible if or anyone we want to do . so there is risk which can be done by stealing data to loss our money .

It has already been done here: http://directory.ioI think this basically answers OP's questions. Just look at that database and the ridiculous number of pages (904625697166532776746648320380374280100293470930272690489102837043110636675). Do you think it would be easy to search for a certain address that you want to hack in that big database? No. I think it would take years or even decades before you can even hack a Bitcoin address using that database unless you got lucky and found the address that you were looking for at the top part of that list. Maybe if someone designs a killer searching algorithm that will let you go through that much number in such short period of time, then we're all doomed.

what do you mean by brute force? if you think someone can find private key from public key then it is impossible. but if you are thinking about brute forcing an encrypted private key, then it depends on the encryption method that was used and the password used for that encryption so it can be possible or impossible depending on what I said. I meant he generate all the private keys which are possible and then search them using the addresses . Isn't that correct
it is possible but it takes until the end of time to generate a small portion of total private keys.

Tell me what you guys think about this.
Let's consider for a moment that the FBI, NSA and all powerful government agencies has a lot of computing power and are able to bruteforce passwords made of very strong encryption. No matter how much computing power these agencies have, they cannot bruteforce more than a few private keys and for this they will take maybe 20-50 years on an optimistic note. Because private keys are random combination it is very very hard to bruteforce them. So in the end I can say 100% sure that for the moment we are very safe from this point of view, who knows what happens in the future.

What if someone got lucky and went onto a page and found a public key with 100+ BTC on it ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) Then i think the owner of that address will think that Bitcoin addresses can get hacked and their trust from the system might fade away. Am i wrong ?

somehow i don't think that is possible to break someone address by brute force, its going to take very very long time to do it, and the success chances for cracking someone address is really slim, but it is not impossible, that is why we don't recommended to put many coins in a wallet

to get private key of a known public key it would take many days to get the exact match. take all 26 alphabets and all 10 numbers and you would millions of string so it's not a cup of tea for everyone.
but luckily if you could find the private key by brute force and you found 0btc so what's the use.

regardless to OP story when the one who brute force succeed and taking over all addresses on bitcoin's world,however the one who doing bruteforce would be depressed trying to take over all the addresses but none of his attempts succeed

if anyone getting profit in legit way than he will not do scam . since it is a matter of chance that no one knows the admin of main block of mining . but i will say all things in this are safe and reliable .

IIRC there are 2^160 possible addresses. So 2^160 private keys. Even with the current market, we didn't even use 0.01% of it(no research here, it's just obvious that we didn't generate that many addresses), so brute forcing would be stupid or a lucky strike.

The keyspace of the possible Bitcoin address is extremely huge and it makes it IMPOSSIBLE for anyone to even get an used Bitcoin address in their entire lifetime. This is possible if the address generation is not random and thus making the address weak.
The closest thing that you can get to have control over several addresses at once is trying to crack the xpriv keys and that is also impossible. That would grant you access to all the addresses that can be generated under that.

ok lets worse case scenario this.
lets imagine all possible private keys at binary level from 00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000-00000000- 00000000-00000000-00000000-00000000-00000000-00000000 to 11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111-11111111- 11111111-11111111-11111111-11111111-11111111-11111111
you may think that 20 bytes looks small but its not the case of changing a bit 160 times. its instead progressively more changes as you go through it.
EG lets start with 3 bits its not 000 001 011 111 done its 000 001 010 011 100 101 110 111 done
adding another bit is not just one extra change, but double 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1111 done another bit, again double
even with the 160bit limitations it is 1461501637330900000000000000000000000000000000000 combinations imagine you processed 1000 combinations a second thats only 31536000000 combinations a year. meaning you will process all combinations in 46343912903694300000000000000000000000 years
lets say you could do 1trillian combinations a second thats only 31536000000000000000 combinations a year. meaning you will process all combinations in 46343912903694300000000000000 years
remember a person only lives ~99 years and has become a grandparent (3rd generation) in that time so to get to 999 years your descendants need to hand your project down the lineage of offspring 20 times the next digit (9,999 years) is passing it down your lineage 4000 times the next digit (99,999 years) is passing it down your lineage 80000 times in short even if a caveman done 1trillian combinations a second, their modern day ancestor would not have got that far.
