(2026-02) NIROPoK-Based Post-Quantum Sidechain Design on Ethereum
2026-02-26
This paper presents a pioneering approach to constructing sidechains on the Ethereum network with a focus on post-quantum security. Our framework integrates a novel quantum-resistant version of a non-interactive random oracle proof of knowledge (NIROPoK) scheme, alongside a quantum-resistant proof-of-stake mechanism and a post-quantum bridge based on the Dilithium digital signature scheme. By harnessing these advanced cryptographic techniques, we establish a robust defense against quantum computing threats while ensuring enhanced privacy for blockchain transactions. By conducting a thorough analysis and implementing our approach, we demonstrate the feasibility and effectiveness of creating quantum-resistant sidechains within the Ethereum ecosystem. Our proposed sidechain is also capable of securing Ethereum transactions from quantum threats using Ethereum’s current architecture and security measures.
