`eth2_network` forgets to descore peers when opening connection times out. It only descores when opening the connection succeeds and then there is a subsequent error. The caller cannot distinguish the cases, so ensure that the descore is also applied if the request fails during its initial portion. |

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
