Quantum Computing Threatens Blockchain Cryptography and Requires Urgent Migration
Recent research indicates a significantly accelerated timeline for quantum computers to break current blockchain cryptography, particularly Shor's algorithm which undermines elliptic curve digital signature algorithm (ECDSA) based security. This poses an existential threat to all cryptocurrencies, n…
Ethereum's Post-Quantum Upgrade: Strategic Opportunity, Hash-Based Signatures, and a 2029 Completion Target
Justin Drake (Ethereum Foundation researcher) argues that quantum computing has shifted from theoretical to material threat in 12–18 months, driven by algorithmic improvements reducing the qubit requirement to break ECDSA from tens of millions down to ~100,000 physical qubits, plus a 10x surge in qu…
Bitcoin's Quantum Threat: A Governance Crisis Disguised as a Cryptographic Problem
Two papers released in April 2026—from Google and the Oraic/Caltech group—dramatically lowered the estimated physical qubit thresholds required to break ECC-256, with the neutral-atom paper suggesting as few as 10,000–26,000 physical qubits versus prior estimates of hundreds of thousands. Critically…
