More on collisions and their ramifications for bitcoin later, but along the way the LBC is using its computing power to try and bust open bitcoin wallets owned by other people, and potentially taking the coins inside. The basics are this: bitcoin addresses containing funds can be accessed by private keys, which are generated at the same time as the address.

Technically, a number of private keys could work with any given address, but you'd need a huge amount of computing power to brute force your way through enough possibilities to find any of them. The LBC attempts to accomplish this by recruiting the computing power of anyone who's willing to download and run their software.

Finding a private key that works with an existing wallet is a fast-and-loose version of "cracking," and gives the attacker access to all the funds inside. But when someone in the LBC pool finds a working private key, do they get to keep the coins? He would only tell me that he's a computer programmer "past his 40s," who lives in Europe. The LBC has been working for just under a year. So far, Rico claims, the project has generated over 3, trillion private keys and checked them against existing bitcoin addresses to see if they work, and has found three that do and contain bitcoin.

They've found over 30 private keys in total, some of which are for so-called "puzzle" addresses that are suspected to have been generated as easy bait for crackers. Cracking wallets may seem malicious on the surface—and if an LBC participant knowingly steals funds, it might just be—but it also has research value.

Bitcoin security researcher Ryan Castellucci has done work cracking wallets as a proof-of-concept in order to model attacker behaviour and defend against it. But cracking wallets is just one part of the LBC's mission. The other is to find a genuine cryptographic collision, which would mean it's possible to generate inputs that, when put through the bitcoin address hashing algorithm, generate an identical pair.

If it were ever to happen, bitcoin would have to use a new cryptographic algorithm for addresses. This would be similar to Google creating a collision with the once-popular SHA-1 cryptographic algorithm , which ended its usefulness for good.

Bitcoin, Altcoins and Ethereum address collision mining software for cracking private keys. Bitcoin, Altcoins and Ethereum address collision mining software. The unique feature about this software is that each generated private key is tested against millions of Bitcoin, Altcoin or Ethereum addresses.

But instead of new physics , the Large Bitcoin Collider is hunting cryptographic collisions—essentially proving that a supposedly unique and random string of numbers can be duplicated.

If it were ever to happen, bitcoin would have to use a new cryptographic algorithm for addresses. Now, the blockchain finishes synchronizing. What happens? Is this a possibilty, sans the astonishing improbability? After all, random number generation can be influenced. If this happens, then Person B will be able to spend person A's bitcoins. However, there are only two ways this can happen:. For "a" to happen, person B would need to break "secpk1".

I am no expert on this field, but from what I can find on bitcointalk. And if you're wondering how strong that is, then look for the video "Exhaustive search attacks" from Dan Boneh. So somehow breaking both or randomly generation a key which hashes is exactly the same as another bitcoin address, is highly unlikely.

There is also a chance for you computer to catch on fire, and some of the materials to melt together into a lotto coupon with winning numbers on and a valid barcode , but it just won't happen because of the chance is so unbelievably small it's the same with the " click and generate another persons bitcoin address ". EDIT Woops, one important thing: This all assumes that all bitcoin addresses are properly generated using "true random". All brain-addresses and addresses generated using a bad PRG, might be easy to find by either using a flaw in the PRG or exploit the flaws in the human brain.

This is the way I see it. The total number of bitcoins that will ever be mined is 21 million. The smallest bitcoin unit is a satoshi 0. If we place all possible satoshis into a wallet of their own, we would get the maximum number of wallets that could have any balance to them so the actual number of wallets with bitcoins is obviously less.

An incredibly small number. If B has not downloaded enough of the block chain to see A's transaction, then the situation will be as described above. When blocks are downloaded by a wallet client, the transactions therein are checked to see whether any of them send coins to addresses held in this wallet. If so, those coins are added to the wallet's balance. So B will see an extra 25 BTC appear in his wallet. As mentioned in the other answers, he'll be able to spend them as if they were his own.

So it's a race between A and B to see who spends them first - either can do it. If B has already downloaded the relevant transactions before generating the colliding address, the situation is a little different. As far as I know, most Bitcoin clients, when generating a fresh random address, will not rescan the block chain to see whether it contains any transactions sending coins to that address.

As described above, the probability of this happening is infinitesimally small, so for all practical purposes, such a scan would just be a waste of time and resources. Of course, barring RNG faults, this question is sort of like asking "If all 50 US state governors were simultaneously struck by lightning, how would the stock market be affected?

I suspect the simple answer is that Person B would be able to spend Person A's bitcoins, as he would show up in the ledger as owning them. Not dissimilar from simply giving someone your wallet. The address space of 2 is not the probability or "strength" of anything other than the probability of picking a value in the address space. The probability of 2 people having the same bitcoin address is actually a lot higher than people may suspect by faulty intuition. In fact, the likelihood of collision is related to the Birthday Problem read about it.

As the number of people and addresses generated increases, likelihood of a collision increases close to exponentially. Given a few million users each generating a new address per month, the likelihood of a collision is such that it could occur several times in a lifetime, especially as we're dealing with hashes or hashes of hashes.
