Separate groups discussion on the network anonymization protocols (Some are fictional at this point):
- [Kovri](https://github.com/monero-project/kovri) - used in Monero. Onion routing style like tor but different approach (DHT Node discovery, Uni-directional routing (closer to free route mixnets), designed for low latency networks, probably works well for P2P but may not work well for client-server architecture).
- If used in Blockchain networks, it can't be used for miner nodes, as the high latency might lead to network forks and higher rate for orphaned blocks.
- Some discussion on possible attacks such as [eclipse attack](https://www.usenix.org/node/190891), [sybil attack](https://en.wikipedia.org/wiki/Sybil_attack), 51% attack.
