原标题：What happens if 2 people generate the same bitcoin wallet address?
问：If person A generates a bitcoin wallet address and has say 2 bitcoins and person B generates the same address, can Person B spend Person A's bitcoins?
1.yes, but you've got more chance of being killed by a bus
2.Yes he can. There are a lot of threads though explaining that this is not something that will happen in the next million years...
3.i belive it has happend once and only once so far. im not sure if it was true or not but there where threads about it some time ago.. anyhow if you generated 1000 bitcoin addresses a second for a million years i think it works out at a 50% chance so yeh not very likely
4.This would be called a "collision" and is highly unlikely.
Keys are 256 bit in length and are hashed in a 160 bit address.(2160th power) Divide it by the world population and you have about 215,000,000,000,000,000,000,000,000,000,000,000,000 addresses per capita.(2.15 x 1038)
键长256比特，在一个160bit位的散列地址。（2160th）除以世界人口有人均约215000000000000000000000000000000000000地址。（2.15 x 10 ^ 38）
5.The odds are astronomical, something like there being more bitcoin addresses than atoms in the universe. A very large number.
