No just straight clone.
Maybe just the address to the way bitcoin does it..... maybe just that.
Or if easy, replace also the persistence implementation.
Replace persistence after first release.
Does this mean you're going to make the code available again, the one on github that you took offline recently? I think you promised it 2-3 days ago:
No, that is old cold.
The clone will just be the refactored version, removing all legacy Nxt code from earlier blocks.
So changes are very simple.
(1) Change address mechanism
(2) Change how money is handled
(3) Change persistence
(4) Remove all old Nxt block chain code
That is all that is needed.
If I really work on it, I should be ready by the weekend.
I think I will rename this project NIX. Give it all to the community. You will need to register your own domains to promote it. I will just maintain the code.
