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
