What You Will Learn

Six structured modules covering the full spectrum of quantum threats to blockchain and the practical steps to build resilience. No prior quantum physics knowledge required.

1

Blockchain Fundamentals and Quantum Vulnerability

  • How blockchain consensus mechanisms work and where quantum attacks apply
  • Digital signatures at risk: ECDSA, EdDSA, and Schnorr under quantum threat
  • Why "quantum-proof" claims from blockchain projects often miss the mark
2

Quantum Computing and Cryptanalysis

  • Shor's algorithm and its direct threat to public-key cryptography in blockchains
  • Grover's algorithm and its implications for hash functions and mining
  • Realistic timelines: when quantum computers will reach cryptographic relevance
3

Post-Quantum Solutions for Blockchain

  • Lattice-based and hash-based signature schemes for blockchain
  • NIST PQC standards and their applicability to distributed ledger systems
  • Migration strategies: upgrading live blockchain networks without breaking consensus
4

Quantum Random Number Generation for Blockchain

  • Why pseudorandom number generation is a weakness in smart contracts and DeFi
  • How QRNG improves security for key generation, consensus, and randomness oracles
  • Practical integration of QRNG hardware with blockchain infrastructure
5

Cryptocurrency and DeFi Security

  • Quantum threats to Bitcoin, Ethereum, and major cryptocurrency protocols
  • Smart contract vulnerabilities in a post-quantum world
  • Protecting wallets, exchanges, and staking infrastructure against quantum attacks
6

Building a Quantum Resilient Blockchain Strategy

  • Assessing quantum risk for your blockchain platform or portfolio
  • Governance frameworks for quantum readiness in decentralised systems
  • Timeline-based roadmap: what to do now, next quarter, and next year

Who Should Take This Course

Blockchain Developers

Understand the specific quantum vulnerabilities in consensus mechanisms, signature schemes, and smart contracts. Learn which PQC alternatives apply to your platform.

Security Teams

Assess quantum risk to your organisation's blockchain infrastructure, custody solutions, and DeFi positions. Build a practical timeline for quantum resilience.

Investors and Fund Managers

Evaluate quantum risk across your cryptocurrency and blockchain portfolio. Understand which protocols are preparing for the quantum transition and which are not.

Policy and Compliance

Regulatory implications of quantum threats to blockchain, digital assets, and CBDCs. Build governance frameworks for quantum readiness in decentralised systems.
