Sure there is-- block 0 contains coins 0-49, block 1 coins 50-99, etc.
If you get sent 500 bitcoins, they can all be traced back to generation transactions, so you "own" a bunch of little pieces of land in bitcoin-world.
It will be really nice if one day I can say:
"Here is my 500 BTC, it represents all the land north of Dover, in the state of Delaware. It's easily verifiable that no one else owns this piece of land" (in bitcoin-world of course).
That will make me feel REALLY rich
I think it's technically
possible to trace every bit-dust back to its origin, just like every gold atom
should be able to be traced back to the location where it was mined. If such information is recorded.
