Quantum and blockchain convergence
summary
Blockchain relies on ECDSA to protect roughly $3 trillion in crypto but that math can be broken as compute power rises from GPUs toward true quantum qubits, enabling key recovery; NIST signals migration and timelines that imply Post-Quantum Cryptography adoption by around 2030, and regulators (US bill 2019/2020) already push post‑quantum for government contracts. Practical notes: a working quantum-capable attack model, migration costs, and proposals like BIP 360 for Bitcoin are discussed along with a quantum-proof blockchain effort (Quranium).
