Can a bitcoin address can be recovered from public key???

[lightenx]

Crackning a private key.... against the Universe, Satoshi and Bitcoin. Whichever tools you find, they will be all fake.

[sana9821]

i really doubt that it is possible at least not with the computers that we have nowadays if we would be able to do that wouldnt bitcoins be not safe?

[LFC_Bitcoin]

Its not impossible, its just very very low probability

^^

This.

One of the reasons bitcoin is such a pioneering invention/discovery is because of it's unique security features. Bitcoin would be pointless if you could easily crack a wallets contents by using the public key.

[Omikifuse]

In theory no, because the odds of collision would be the same as an meteor destroy earth in the next seconds.

But if your random number generator is broken, maybe

Holy hell, will people please read replies before adding to the mess?

Short answer: Yes, of course a bitcoin address can be recovered from a public key. 

Longer answer: See replies by pjsonowal.

No it is not. A public key can not be reverse engineered back to its privkey and you cannot actually recover a privkey using bruteforce. It is a mess but if you put information like that, you will just cause confusion, and thus, a mess.

[jonald_fyookball]

Most bitcoin users never need to worry about publickey. 

[CIYAM]

No it is not.

Yes it is - do you understand that the question does not mention "private key" but instead "public key" or did you simply not read it?

It is a mess but if you put information like that, you will just cause confusion, and thus, a mess.

Unfortunately it is you (and most other posters in this topic) that are causing the mess and confusion by not even bothering to read the OP.

To the @OP - unfortunately this is why this forum is no longer very useful for any sort of technical advice.

Yes, it can be. Try reading some posts before you and the question in OP.

As for Evil-Knievel, I've seen him plenty of times here in this forum conducting bounties for certain projects related to bitcoin's cryptography. On the linked thread, he attacked the weak addresses present on the curve, but I'll doubt that he would continue on doing that and actually break the code.

[TastyChillySauce00]

thats impossible ,as i read on blockchain TOS (CMIIW) , if you lose your address and forgot to backup , than you lose your money

[Djisamsoe]

no wa,public key as i know just can move some bitcoin from other wallet.

[shorena]

Can we rename the thread wall of shame please?

No it is not.

Looks like you are the only one to actually read the question indeed.

I think people just automatically assume private key whenever someone starts talking about recovering something from an address.

[ranochigo]

The only way you could do such a thing is if you know the public key originated from a brain wallet and you are able to figure out the words used on the wallet by possibly being very close to that person.

So thats why brainwallet is closed permanently for these security issues...

Nope, brainwallet is known not only for their possible lapse in human mind but also the insecure algorithm used to generate them. There was recently a hacking tool that was revealed and it could potentially cause people to lose money.

Can a bitcoin address can be recovered from public key... If not so how is it related to bitcoin address???

Only he can.

[FanEagle]

Only Chuck Norris can, and I tell you, he just need to blink once to find the private key!
But returning on the natural world: Only if you can win 3 max prize lotteries in a row you can find it.

Talking about chances:

Finding the same bitcoin address (with private key) = 1 in 2^160

Compare to: [BAD THINGS]
1. Being killed by a vending machine. (1 in 112 million)
2. Being killed in a terrorist attack on an airline. (1 in 25 million)
3. Dying from a bee, hornet or wasp sting. (1 in 6.1 million)
4. Dying from being left-handed and using a right-handed product incorrectly. (1 in 4.4 million)
5. Dying in a plane crash. (1 in 1 million)
6. Being killed by flesh-eating bacteria. (1 in 1 million)
7. Getting Struck by Lightning. (1 in 1 million)
8. Drowning (1 in 2,000,000)
9. Drowning specifically in a bathtub. (1 in 840,000)
10. Dying in an on-the-job accident. (1 in 48,000)
11. Being murdered…just in general. (1 in 18,000)

Compare to: [GOOD THINGS]
1. Having identical quadruplets. (1 in 15 million)
2. Becoming US president. (1 in 10 million)
3. Becoming a Movie Star. (1 in 1,505,000)
4. Becoming an astronaut. (1 in 12,100,000)
5. Getting a royal flush in a first hand of poker. (1 in 649,740)
6. Winning an Olympic gold medal. (1 in 662,000)
7. Becoming a pro athlete. (1 in 22,000)
8. Winning an academy award. (1 in 11,500)
8. Finding out your child is a genius. (1 to 250)
9. Dating a millionaire. (1 to 215)

HOWEVER, the chance of finding the same bitcoin address (with private key) is still higher than the chance that YOU exist:



So, there is still a chance!!!

Guys the things are now messing up here...

i asked only the question that CAN A BITCOIN ADDRESS CAN BE RECOVERED FROM PUBLIC KEY??

and i got the answer - "NO"

reason:-https://www.comodo.com/resources/small-business/digital-certificates2.php

there is only two-three points that can recover your address:-
1) private key
2) mnemonic
3) email address and phone no. that was linked to the address(if you had made via blockchain)

[pjsonowal]

and talking about evil-kennevel guy, i think it was his own address and he made it seem like other account.

IF NOT I CHALLENGE HIM TO CRACK MY ADDY.

Your question is misleading. Normally the public key is the address. And for full access, to spend the funds, you need the private key.

Now, you forgot about "vanity generator" which in theory can give you the private key of a bitcoin address you want (or at least based on a pattern).
But you will not live long enough for that to come out from vanity gen.

As somebody said, only Chuck Norris can help, since he already counted to infinite and back, twice
