Google Report Highlights Quantum Vulnerabilities for Major Cryptocurrencies
- The Google quantum report identifies vulnerabilities in Bitcoin, Ethereum, and other networks due to advancements in quantum technology.
- The XRP Ledger has implemented post-quantum ML-DSA signatures on its testnet to enhance security against these threats.
- Bitcoin faces an increased risk of an on-spend attack, potentially allowing the theft of BTC within approximately nine minutes using quantum computing techniques.
- Ethereum is less vulnerable to on-spend attacks but faces risks from at-rest attacks, particularly concerning its consensus-layer BLS signatures.
- Google estimates a success rate of up to 41% for attackers exploiting Bitcoin’s vulnerabilities under optimal conditions.
The report emphasizes the urgency for blockchain networks to transition to post-quantum cryptography (PQC) by the projected timeline of 2029, as many current systems remain susceptible to quantum threats.
With Bitcoin at risk of an on-spend attack and Ethereum facing distinct vulnerabilities, the need for proactive security measures like those seen in the XRP Ledger is crucial for safeguarding crypto assets.(Source)
