Caltech and startup Oratomic report a quantum machine running Shor’s algorithm could need only about 10,000 qubits to break today’s public‑key encryption—far fewer than prior million‑qubit estimates. That reduction tightens the timeframe for risks to Bitcoin private keys.
Google updated its estimates, saying far fewer qubits are required to break elliptic curve cryptography than previously thought, increasing pressure on crypto stakeholders to prepare for a post‑quantum future.
Google has set a firm corporate deadline to move all authentication services to quantum‑resistant cryptography by 2029, a timetable that aligns with Ethereum's previously stated eight‑year target. Bitcoin developers have not issued a public response, leaving potential risk windows for users and custodians.
Google announced it aims to finish migrating to post-quantum cryptography by 2029, framing the move as a proactive step to protect services from future quantum threats. The timeline signals a major push to harden internet and cloud security ahead of widespread quantum capability.
Oracle has released Java 26 with 10 new JEPs focused on AI integration, cryptography, and performance, and has expanded the Java Verified Portfolio to include Helidon and JavaFX support.
IBM is broadening access to its quantum processors, prompting developers to accelerate work on post‑quantum defenses as a future risk to Bitcoin's cryptography.
Veteran crypto researcher Justin Bons warned on X that quantum computers could potentially break privacy protections in Zcash and Monero. His post has reignited debate over the quantum resilience of cryptographic primitives used by leading privacy coins.
The Ethereum Foundation has made post-quantum security a strategic priority and formed a dedicated Post‑Quantum team to work on leanVM and post-quantum signatures. The effort aims to prepare ETH and the wider ecosystem for the long-term risk posed by quantum computers.
Ethereum has made post‑quantum cryptography a strategic priority with a dedicated PQ team and $1M in rewards, but hash‑based signatures are about 40x larger and could cut throughput and raise fees.
The Ethereum Foundation has committed $2 million to strengthen the network's core cryptography and is backing a new security effort; developers will hold biweekly sessions on quantum‑resistant transaction design. The move aims to prepare the protocol for future quantum risks and speed coordinated upgrades.
