Ledger CTO Warns of New Cryptographic Threats to Bitcoin
Ledger CTO Charles Guillemet has warned that two new cryptographic breakthroughs could pose a long-term threat to Bitcoin (BTC). Guillemet, in a post on X, mentioned a recent study by researchers at Ruhr University Bochum and the Max Planck Institute for Security and Privacy, which presents a subexponential algorithm that might solve the elliptic-curve discrete logarithm problem more efficiently. Guillemet emphasized that current cryptographic schemes remain secure, but the new algorithm could be more efficient for hypothetical large-size curves. The second breakthrough involves a significant reduction in the estimated quantum circuit cost for quantum computing attacks on elliptic-curve cryptography.
