Last week, Google [accelerated](https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/) its timeline for the post-quantum reality to 2029.

Today, the tech giant's quantum and artificial intelligence team released a new research paper, warning that number of quantum computation units required to break elliptic curve cryptography schemes is 20 times less than previously thought.

### What's the Scoop?
- **Accelerated Timeline:** On March 25, Google [revised](https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/) its timeline for the post-quantum reality, advising cryptographic systems to target full migration by 2029. Until now, the tech giant has been aligned with the [NIST timeline](https://www.csoonline.com/article/3604824/nist-publishes-timeline-for-quantum-resistant-cryptography-but-enterprises-must-move-faster.html), which specifies 2030 for deprecating quantum-unsafe algorithms and their full disallowance by 2035.
- **Breaking Signature Schemes:** Today, Google Quantum and AI released a new [research report](https://research.google/blog/safeguarding-cryptocurrency-by-disclosing-quantum-vulnerabilities-responsibly/), which demonstrated that future quantum computers could potentially break elliptic curve cryptography schemes (which protects crypto wallets and other systems) with twenty times fewer qubits and gates than previously realized.

### What's the Take:
Elliptic curve cryptography secures everything from Bitcoin and Ethereum wallets to digital signatures, meaning a successful quantum attack would undermine foundational blockchain security.

Now, its timeline to obsolescence is *collapsing *as the timeline for a post-quantum reality rapidly accelerates.

Satoshi suggested that Bitcoin can *gradually* adjust to a post-quantum reality more than a decade ago, but that window is closing faster than expected.

Now, some contemporary Bitcoin champions have begun [shouting](https://x.com/nic_carter/status/2036926418399965529?s=20) with newfound urgency, warning that elliptic curve cryptography is nearing obsolescence and that without a shift toward cryptographic agility, Bitcoin risks falling behind more proactive ecosystems like Ethereum.

The Ethereum Foundation recently [launched](https://www.bankless.com/read/news/ethereum-foundation-launches-website-dedicated-to-post-quantum-ambitions) a dedicated post-quantum portal, which is a comprehensive repository of post-quantum (PQ) information pertaining to Ethereum, the product of 8+ years of research from the EF's Protocol Architecture and Protocol Coordination teams.

> Google just released a warning for cryptocurrency that the number of qubits required to break ECDSA is 20x less than previously thought.They have proof.They’re (strongly?) recommending crypto upgrade to post-quantum by 2029 now.4 years!?Timelines are accelerating rapidly.
