Quantum Computing and Cryptocurrency Security: Post-Quantum Signature Schemes, Network Migration Timelines, and Investor Risk Management
Why Quantum Computing Matters for Crypto Security
For more than a decade, cryptocurrencies have relied on classical public-key cryptography such as ECDSA and EdDSA. These algorithms are considered secure against traditional computers but can be broken in polynomial time by a sufficiently large quantum computer running Shor’s algorithm. Although
