Private Key, Public Key, Bitcoin Address and the Blockchain | Bitcoins Pakistan
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. Thank you for your interest in this question.

What happens if your bitcoin client generates an address identical to another person's?

How many Bitcoin addresses are there? Well, it has already happened. Snap Apr 6 '16 at However, there are only two ways this can happen: Nicolai 1, 10 Your case "b" is a multi target second pre-image, not a collision. You want to match the hash of an existing message you can't influence. A collision would be Person B creating two distinct inputs with the same hash. As suggested by its name, Leo Minor is considerably smaller than Leo; the latter covers square degrees, while the former only covers square degrees.
