* batch attestations * Fixes (but now need to investigate the chronos 0 .. 4095 crash similar to https://github.com/status-im/nimbus-eth2/issues/1518 * Try to remove the processing loop to no avail :/ * batch aggregates * use resultsBuffer size for triggering deadline schedule * pass attestation pool tests * Introduce async gossip validators. May fix the 4096 bug (reentrancy issue?) (similar to sync unknown blocks #1518) * Put logging at debug level, add speed info * remove unnecessary batch info when it is known to be one * downgrade some logs to trace level * better comments [skip ci] * Address most review comments * only use ref for async proc * fix exceptions in eth2_network * update async exceptions in gossip_validation * eth2_network 2nd pass * change to sleepAsync * Update beacon_chain/gossip_processing/batch_validation.nim Co-authored-by: Jacek Sieka <jacek@status.im> Co-authored-by: Jacek Sieka <jacek@status.im>
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
