BLS Aggregated Signature Experiment

Question: Can we aggregate signatures that are already aggregated? (i.e., aggregate aggregated signatures)

Experiment Setup: We create a simple example that builds an aggregate signature and aggregates it with another signature.

Finding: We are able to verify each public key and its corresponding message with the final aggregate signature.

What does this mean? Open questions:

• What is the upper bound on the number of messages we can aggregate?
• Can we aggregate the entire block history with just 1 aggregated signature?
