# Aggregator

The Aggregator collects [Operator](/architecture/1_proof_verification_layer/4_operator.md)'s BLS Signatures.

When the quorum of responses is reached, the Aggregator will submit a Task Response with the aggregated signatures back to the [Aligned Service Manager](/architecture/1_proof_verification_layer/3_service_manager_contract.md).
