Komodo is separate from zcash right?
Yes they are two different coins. Komodo adds features that are not found in Zcash.
What are the features that it adds? I read that it uses the Bitcoin blockchain. There's no way for it to be traceable there right?
Features that Komodo adds by itself:
Delayed Proof of Work - submission of notarized hashes to maintain blockchain integrity of third party and self-generated chains.
Assetchains: Create your own Zcash fork from command-line
Features SuperNET tech contributes:
DEX - Decentralized Exchange
PAX - Pegged Asset Exchange - speculate on the value of crypto and fiat currencies relative to each other
Ramchains - ultra fast blockchain syncing
Iguana - Multiwallet that allows you to be a full node to multiple coins at once without draining computer resources tremendously
Basilisk - Light Client that can be run simultaenously with Iguana for coins that one does not necessarily wish to support their network.
Future contributions
Gecko - Create your own smart contract/ conditional logic based blockchain
Pangea - Decentralized Poker
Jumblr - Coin Mixer for transparent coins
and others TBA
It submits data to bitcoin blockchain it is not built on top of bitcoin like Counterparty is.
