Aggregation Performance

Analysis of post-quantum signature aggregation and verification in Lean Consensus clients.

This notebook examines:

  • Signature aggregation time
  • Total signatures aggregated
  • Aggregation verification time
  • Aggregation and verification throughput (per second and per slot)
  • Performance comparison across clients
