Google Flags Sub-500,000-Qubit Crypto Risk, Faces Price-Target Cuts on Iran Conflict
Google researchers said some future quantum computers with under 500,000 qubits could break elliptic-curve cryptography, prompting exploration of draft BIP-360 proposals for gradual network upgrades. Meanwhile, major brokerages have trimmed Google’s price targets in reaction to escalating uncertainties from the Iran conflict.
1. Google Quantum Risk Findings
Researchers from Google stated that certain future quantum architectures may require fewer than 500,000 physical qubits to compromise elliptic-curve cryptography used by major blockchains. This revelation has elevated the urgency around assessing long-term exposure and cryptographic resilience.
2. Bitcoin Migration Challenge and BIP-360
In response to the potential quantum threat, developers have drafted BIP-360 to introduce output-specific upgrades that can reduce long-exposure risk. However, Tezos co-founder Arthur Breitman warned that while coding adjustments could be implemented swiftly, migrating billions of keys across a decentralized network will likely span years.
3. Price-Target Reductions Post Iran Conflict
Following heightened tensions from the Iran conflict, several brokerages have lowered Google’s price targets alongside peers Meta and Amazon. The cuts reflect concerns over potential impacts on digital advertising revenue and cloud infrastructure demand in a volatile geopolitical environment.
