Gossip Processing

This folder holds a collection of modules to:

validate raw gossip data before
- rebroadcasting it (potentially aggregated)
- sending it to one of the consensus object pools

Validation

Gossip validation is different from consensus verification in particular for blocks.

There are multiple consumers of validated consensus objects:

a ValidationResult.Accept output triggers rebroadcasting in libp2p
- We jump into method validate(PubSub, Message) in libp2p/protocols/pubsub/pubsub.nim
- which was called by rpcHandler(GossipSub, PubSubPeer, RPCMsg)
a blockValidator message enqueues the validated object to the processing queue in block_processor
- blockQueue: AsyncQueue[BlockEntry] (shared with request_manager and sync_manager)
- This queue is then regularly processed to be made available to the consensus object pools.
a xyzValidator message adds the validated object to a pool in eth2_processor
- Attestations (unaggregated and aggregated) get collected into batches.
- Once a threshold is exceeded or after a timeout, they get validated together using BatchCrypto.

As the first line of defense in Nimbus, modules must be able to handle bursts of data that may come:
