pq-devnet-1: High Level Plan

Objectives

  1. Implement leanSig post-quantum signature signing & verification in lean consensus clients
  2. Implement naive signature aggregation (concatenating individual signatures)
  3. Establish baseline performance metrics for a consensus layer with PQ signatures

Key targets

  • Slot duration: 4 seconds
  • Consensus mechanism: Modified 3SF-mini
  • Validator count: 5 validators (1 validator per client)
  • PQ Signature prameters:
    • Hash chains: 64
    • Chain length: 8
    • Max lifetime: 2^32
    • Activation time: 2^18
  • Signature aggregation: Naive aggregation by concatenating individual signatures

Exclusions

  • Key generation: PQ keys are pre-generated
  • Dynamic validator set: Validator set is pre-determined and fixed at genesis
