Post-Quantum Security Guides
Practical, in-depth guides on quantum threats to cryptocurrency, post-quantum cryptography standards, and quantum-safe blockchain architecture. Written for developers, researchers, and investors.
Post-Quantum Cryptography: A Complete Developer Guide for 2026
NIST PQC standards are final. This hands-on guide covers ML-DSA, SLH-DSA, ML-KEM algorithm selection, liboqs setup, hybrid migration patterns, and a full ECDSA vs ML-DSA comparison table.
Bitcoin Quantum Risk Assessment: Is Your BTC Safe?
A practical guide for Bitcoin holders to assess personal quantum exposure by address type: P2PK, P2PKH reused, unspent P2PKH, and bech32. Includes a decision matrix and the harvest-now timeline.
Implementing NIST Post-Quantum Standards: FIPS 204, 205, and 206
Advanced developer guide for implementing all three 2024 NIST PQC standards. Covers ML-DSA, SLH-DSA, ML-KEM algorithm selection, key sizes, hybrid strategies, and Python code samples using liboqs.
How to Choose a Quantum-Safe Cryptocurrency Wallet in 2026
Consumer guide for selecting a genuinely quantum-resistant crypto wallet. Explains what makes a wallet quantum-safe, why most hardware wallets remain vulnerable, and what to look for in 2026.
Harvest Now, Decrypt Later: The Blockchain Threat Already Active
A deep guide on the harvest-now-decrypt-later (HNDL) threat as it applies to blockchain. Covers what data is being collected, nation-state evidence, which assets are highest-risk, and what structural immunity means.
Building on QuanChain: A Developer Quickstart Guide
Set up a QuanChain development environment, generate ML-DSA key pairs, fund a testnet wallet, send quantum-safe transactions, and deploy your first smart contract. Covers the QuanChain SDK, Three-Channel Architecture, and SpendAndRotate key rotation.
Post-Quantum DeFi Security: Protecting Liquidity Pools and Smart Contracts
Quantum computing threatens DeFi through key theft of LP positions, oracle signer compromise, and multisig quorum attacks. This advanced guide covers the most exposed DeFi components, migration paths to quantum-safe admin keys, and how QuanChain handles DeFi natively.
Quantum Computing Threat Timeline for Blockchain: 2024 to 2035
A beginner-friendly timeline of quantum hardware milestones from IBM Eagle (2021) to current roadmaps through 2035. Covers the NISQ era, the Webber et al. 2022 resource estimates, NIST migration deadlines, and what "cryptographically relevant" actually means.
How to Evaluate Quantum-Resistant Blockchains: A Technical Checklist
A framework for evaluating whether a blockchain is genuinely quantum-resistant or just marketing. Eight criteria covering native PQC implementation, signature algorithms, key rotation, hash function security, consensus exposure, address reuse, NIST compliance, and harvest-now protection. Comparison table for Bitcoin, Ethereum, QRL, and QuanChain.
Enterprise Quantum Security for Blockchain: Migration Playbook
A step-by-step migration playbook for enterprises using blockchain in supply chain, finance, and healthcare. Covers cryptographic inventory (CBOM), risk prioritization by data sensitivity, NIST SP 800-131A timelines, hybrid deployment patterns, and vendor evaluation criteria. References NSA CNSA 2.0, NIST SP 800-208, and NIST IR 8413.
