FreeMoney, yes I knew about that.

Red, very interesting. So, a set of transactions in bitcoin can actually be made local. But it must be possible to control where a transaction should be validated. That must be coin
dependent because of double spending. So, if I understand, it must be possible, for any transaction, to choose which location the resulting coin should be validated in when that
coin is used next time. A random choice would not be good enough. But, are there some problems with an attacker taking over a certain location. The global system had the strength that an attacker would be outworked by the sum of all other CPUs.

Red, can you elaborate more on such a distributed version of bitcoin. Is it described anywhere?

Cheers.
