Lattice-based signature aggregation

The 2.65s verification time is the real bottleneck for consensus integration — that’s longer than a slot. Has anyone looked at splitting this into an optimistic path where validators accept aggregated sigs immediately and
verify async, with a challenge window for invalid proofs? Similar pattern to optimistic rollups but for signature verification. You’d get the compact 74KB proof size benefit without blocking consensus on the verification
latency.
