#### Interop
Unaggregated and aggregated attestations from all shards are sent as `Attestation`s to the `beacon_aggregate_and_proof` topic. Clients are not required to publish aggregate attestations but must be able to process them. All validating clients SHOULD try to perform local attestation aggregation to prepare for block proposing.

#### Mainnet
Attestation broadcasting is grouped into subnets defined by a topic. The number of subnets is defined via `ATTESTATION_SUBNET_COUNT`. The `CommitteeIndex`, `index`, is assigned to the topic: `index{index % ATTESTATION_SUBNET_COUNT}_beacon_attestation`.

### Encodings
Topics are post-fixed with an encoding. Encodings define how the payload of a gossipsub message is encoded.
