Sync committee members produce individual signatures on subnets (similar to the attestation subnets) via `SyncCommitteeMessage`s which are then collected by aggregators sampled from the sync subcommittees to produce a `SyncCommitteeContribution` which is gossiped to proposers.
This process occurs each slot.

##### Prepare sync committee message
If a validator is in the current sync committee (i.e. `is_assigned_to_sync_committee()` above returns `True`), then for every `slot` in the current sync committee period, the validator should prepare a `SyncCommitteeMessage` for the previous slot (`slot - 1`) according to the logic in `get_sync_committee_message` as soon as they have determined the head block of `slot - 1`.

###### Signature
Set `contribution.signature = aggregate_signature` where `aggregate_signature` is obtained by assembling the appropriate collection of `BLSSignature`s from the set of `sync_committee_messages` and using the `bls.Aggregate()` function to produce an aggregate `BLSSignature`.
Set `contribution.signature = aggregate_signature` where `aggregate_signature` is obtained by assembling the appropriate collection of `BLSSignature`s from the set of `sync_committee_messages`s and using the `bls.Aggregate()` function to produce an aggregate `BLSSignature`.
The collection of input signatures should include one signature per validator who had a bit set in the `aggregation_bits` bitfield, with repeated signatures if one validator maps to multiple indices within the subcommittee.
