Networking

This folders hold a collection of modules to:

configure the Eth2 P2P network
discover, connect, and maintain quality Eth2 peers

Data received is handed other to the ../gossip_processing modules for validation.

Security concerns

Collusion: part of the peer selection must be kept random. This avoids peers bringing all their friends and colluding against a beacon node.
Denial-of-service: The beacon node must provide ways to handle burst of data that may come:
- from malicious nodes trying to DOS us
- from long periods of non-finality, creating lots of forks, attestations, forks
