With the introduction of batching and lazy attestation aggregation, it no longer makes sense to enqueue attestations between the signature check and adding them to the attestation pool - this only takes up valuable CPU without any real benefit. * add successfully validated attestations to attestion pool directly * avoid copying participant list around for single-vote attestations, pass single validator index instead * release decompressed gossip memory earlier, specially during async message validation * use cooked signatures in a few more places to avoid reloads and errors * remove some Defect-raising versions of signature-loading * release decompressed data memory before validating message
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
