Good topic.
I would like to ask how it is with assets. All my NXT is currently in form of NXT assets I own. What will happen with those when NXT 2.0 will launch?
Existing Nxt 1.0 Assets or Asset Transaction History will NOT be ported directly to the FNX Child Chain.
Since the Nxt 1.0 blockchain will continue to exist, the Core Team believes it is better to leave the choice of when and how to move to Nxt 2.0 in the hands of the Asset Issuers themselves.
This is probably best done by burning existing Assets, requiring them to be sent to the issuer account in order to issue new Nxt 2.0 Assets in exchange. Or it could be done by each asset issuer declaring a height at which they will take a snapshot of 1.0 asset balances, and then re-distributing those on 2.0.
Assets will be universal on Nxt 2.0, which means that for any Asset, regardless on which Child Chain it was originally issued, any Child Chain that will allow its trade will be able to trade it.
