These include:

  • Lattice-based cryptography (e.g., NTRU, LWE)
  • Code-based schemes (e.g., McEliece)
  • Hash-based signatures
  • Multivariate polynomial problems

PQC Integration in Blockchain Networks

PQC can be embedded in blockchain frameworks in several ways:

  • Utilizing post-quantum signature schemes for transaction verification
  • Implementing quantum-resistant hashing for data integrity
  • Leveraging sidechains to trial PQC without risking main chain operations

BMIC advocates for these strategies, leveraging AI-driven optimization and robust governance to guide organizations through quantum-safe transitions. By integrating PQC in sidechains, blockchain networks benefit from flexible and iterative security enhancement.
