nimbus-eth2/beacon_chain/networking

Networking

These folders hold a collection of modules to:

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

Data received is handed over 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
