Topic: I want firstbits key pair for 1gig - page 2. (Read 8568 times)

OK so differentiating between "valid" and "usable" is a bit pedantic IMHO but let's go ahead and change the language we're using anyway. Whether or not they're valid, they're not USABLE. Let's see what happens if we try to send coins to 3DLCRW4v2zcMoWfk8HH95JvMtQgCKhgKYt with some various clients/services:

Blockchain.info wallet:


MtGox withdrawal:


BitcoinSpinner Android Client:


Bitcoin Wallet for Android by Andreas Schildbach:


I haven't had a chance to test with the Satoshi client yet since this is a work PC and I don't (can't) have Bitcoin installed on it, will update when I get home. At the very least I can say at this moment that none of the web-based or Android-based clients support this Bitcoin address version yet, which makes it largely unusable. I suspect that the 0.6.3 Satoshi client doesn't support them without special configuration either. Even if it does, none of the exchanges, eWallets or other services will send to such an address so it would only be usable in the one direction.

I suspect that all the 3* addresses in the blockchain folks are linking to as "proof" are live tests of OP_EVAL using experimental forks.

oh, but there is a way! just: it's going to take too long. so "an impossibility" is correct for all practical purposes.

He could send a binary message via satoshis and include his email address or something in it.

Or the owner responds and gives you the private key. I doubt he even knows he has it in his wallet, presuming its not lost.

unclemantis if you obtain the privkey for that address we all might as well give up and go home because it would imply that bitcoin is fundamentally broken

No, there's not. This has been proven many many times over. If "where there's a will, there's a way" were true, those hippies in the 60s would have successfully levitated the pentagon. There is no way for you to 1) get the privkey for that address without contacting its rightful owner or 2a) get another key to match those firstbits without 2b) changing the algorithm behind firstbits, which you also can't do.

Just give up on the 1gig firstbits man, it is literally an impossibility.

What site/service is that?  Capitals shouldn't be recognized - it introduces way too much confusion when relaying firstbits.

How about variations like 1gig 1Gig 1gIG and the like? I remember there are both ways to find firstbit addresses, and at least one site/service/script does indeed honour capitals..

Mantis, I am very sure you won't reach your goal on the route you are now. Tell us what you have in mind, maybe there are other solutions..

Ente

Please let us know.... I would like to get at pirates wallet.

3 addresses ARE valid, but they cannot be created in the same way as a 1 address.

I'm not understanding how the 3 addresses aren't valid...their relation to op_eval, multisig, hashes of scripts, etc....but by this link it appears to me that a 3 address can both store Bitcoins and transfer them to a 1 address: https://blockchain.info/address/3DLCRW4v2zcMoWfk8HH95JvMtQgCKhgKYt

Now, please, I don't want to be responsible for killing anyone...if you feel you might rupture an intracranial aneurysm, please stop reading and go see an interventional neuroradiologist or neurosurgeon.

 

Where there is a will there is a way and what ever the way is I will find it!

What, exactly, are you going to ask him? If he can change the algorithm that assigns firstbits because you're so super special? It's not a big database that he can just overwrite or something, it's an algorithm that finds the first address in the blockchain matching 1gig* - it's published, widely used and there's a fair chance that even IF firstbits.com would change their copy of the algo just for you, the community would abandon it for another site that adhered to the publicly published standard.

firstbits 1gig is in use, you're not going to change the algorithm, you're not going to brute force the privkey, just choose a different target and move on with life. It's gone man, it's gone.

PM sent. Thanks!

What is this guy's username on here?

Bitcoin addresses are a 160-bit hash of the ECDSA public key. Given the way Bitcoin's address mechanism works, you don't need to find the exact private key someone else generated, just one that hashes to their address - which is still CRAZY hard but less hard than finding the exact 256 bit private key. How hard?

On a Radeon 5xxx series (the kind a lot of us miners have) you can generate about 23.5 million keys per second. 160 bits of address gives us ~1.46*10^48 possible addresses. At 23.5 million keys per second, it would take you ~6.2*10^40 seconds, a bit under 2*10^33 (that's a 2 followed by 33 zeroes) years to search the entire key space. Realistically you'd probably find your key well before finishing the entire key space, but given that the sun will experience a red giant/white dwarf conversion phenomena in a few billion years and envelop the Earth, but assuming you can become immortal, get to another planet, keep your constituent atoms from decaying along with the rest of the atoms in the universe, and avoid all the black holes everything is collapsing into, you've got about 10^100 years (depending on how accurate our guesses at certain cosmological constants are) to finish calculating all those keys, which is more than enough - assuming you can avoid the heat death of the universe, Bitcoin isn't future proof!

Realistically some breakthrough in tech will invalidate Bitcoin's current encryption schema long before then resulting in a shift to new encryption methods, which isn't that hard to do (as evidenced by the sCrypt() variants out there).

TL;DR: you're entirely unlikely to ever find the privkey of that address with any hardware under any circumstances, ever.

Well .... That is impressive .. Why I did hear about a quantum computer? How the light can solve this? As I understand it , just change the mediator (the light instead of electrons) - the rest remains the same ..
