A competitor to nxt ?
What's the advantage over
Nxt?
NXT (or Qora for the matter) do not support custom-blockchains on top of the main one. You can create smart properties and assets, but they all will be working under same basic NXT protocol rules.
In case of Crypti, a developer will be able to launch a new blockchain, which while connected to main chain, could contain it's unique processing rules and capabilities.
