But what is to stop some of those addresses from being the same?
- Randomness
- An extremely large set of potential addresses that can be created
- The fact that if the most efficient technology possible (based on our current understanding of physics) were to somehow harvest all of the energy of the sun, all of the possible Bitcoin addresses would not be generated after a thousand years
All these points are based on probability.
But I want to know how sure a repeated bitcoin address is prevented?
I knew bitcoin address can be generated in offline too.
I guess a time based and System ID or/and IP based coding must be there to prevent a repeated address.
