Talk about the Nym Mixnet, a "decentralized incentivised mixnet + private credential".

Overlay network (like I2P)
Onion routing (like I2P)
Based on the Loopix design
Sphinx packets
Packet re-ordering and timing obfuscation
Cover traffic
Single Use Reply Blocks (SURB)

Network directory -- set of validators running a consensus protocol (apparently a blockchain?); keeps track of all mixnodes and gateways
Mixnodes are rewarding with NYMs for mixing network traffic
NYMs can be used to acquire bandwidth credentials (coconut credentials)

"Coconut credentials" break linkability betwen identity and the right to use a service

Currently at around 500 mixnodes
