1) How 0x works is a combination of centralised and decentralized exchanges. It draws from the best of both worlds: it cuts out third parties through smart contracts which ensure users are in control of their funds, yet maintains the lower costs associated with running centralised exchanges through something called off-chain relays.
2) 0x tokens (ZRX) are used to pay the relayers. They can also be used to vote on 0x protocol improvements.
