Abstract

This research introduces a novel consensus protocol specifically designed for resistance against quantum-enabled adversaries. The authors propose a hybrid mechanism that integrates quantum-resistant signature schemes directly into the validator selection process. By utilizing a zero-knowledge proof framework alongside post-quantum cryptographic signatures, the protocol ensures both transaction privacy and ledger integrity in a hypothetical post-quantum environment. The methodology involves simulations of network performance under varying quantum adversarial conditions, comparing the proposed protocol against standard PoW and PoS implementations. The key contribution is the demonstration that quantum resistance can be achieved without catastrophic losses in decentralization or performance if the consensus layer is re-engineered to support smaller, hardware-accelerated signature verification.

Key findings

  • Hybrid consensus models provide higher resilience than single-signature approaches.
  • Zero-knowledge proofs can be leveraged to maintain anonymity while ensuring quantum safety.
  • Hardware acceleration is vital for managing the overhead of post-quantum verification.
  • Decentralization need not be sacrificed for quantum resistance.
