Nic Carter Says Ethereum Is Ahead of Bitcoin in Quantum Threat Preparedness

Ethereum Takes Action While Bitcoin Lags Behind

Castle Island Ventures partner Nic Carter has issued a stark warning about the crypto industry's readiness for the quantum computing era. According to Carter, elliptic curve cryptography — the backbone of most blockchain security — will become completely obsolete within the next 3 to 10 years. He urged the industry to accept this reality and start acting immediately.

In a post on X, Carter drew a sharp contrast between the two largest crypto projects:

"best in class approach: — ethereum gets together and announces a specific, detailed PQ roadmap by 2029. sets it as top strategic priority. folds PQ into ongoing roadmap. detailed FAQ. no fear, just action. worst in class approach: — Bitcoin devs…" — Nic Carter (@nic_carter), original post

The investor stressed that the only thing that matters right now is how quickly developers realize the need for cryptographic agility — the ability to swiftly upgrade encryption algorithms as quantum threats materialize.

Why This Matters

Quantum computers pose a fundamental threat to the cryptographic foundations of all digital assets. The encryption schemes and digital signatures securing billions of dollars in cryptocurrency could become vulnerable once sufficiently powerful quantum machines come online. Proactive migration to post-quantum algorithms is not a distant concern — it is an urgent priority that will determine which networks survive the transition.

The Ethereum team has presented a concrete roadmap for quantum-proofing the network, targeting completion by 2029. Post-quantum security has been designated a top strategic priority, with new algorithms folded into the project's ongoing development plans. The team also published a detailed FAQ to address community concerns. Carter characterized Ethereum's approach as "no fear, just action."

By contrast, Carter labeled Bitcoin developers' approach as the worst in class, though he did not elaborate on the specifics of their shortcomings.

Google's Post-Quantum Transition

The urgency extends well beyond crypto. Google has revealed its own post-quantum cryptography transition plan, aiming to fully implement new encryption algorithms by 2029. The tech giant has updated its corporate threat model and is prioritizing the migration of authentication services to quantum-resistant protocols.

Key steps in Google's strategy include:

• Adding post-quantum digital signature protection (ML-DSA) to Android 17.
• Integrating similar protections into the Chrome browser.
• Upgrading cloud services with quantum-resistant encryption.

Google's assessment is that future quantum computers represent a real threat to current encryption standards and digital signatures, making preemptive upgrades essential.

Early Steps Toward Quantum-Resistant Bitcoin

On March 19, BTQ Technologies launched a Bitcoin testnet equipped with quantum-resistant protections. This experiment represents one of the first practical attempts to test post-quantum algorithms on Bitcoin's architecture.

The race for quantum resilience is accelerating across both the tech industry and the blockchain space. Major corporations and crypto projects alike recognize that the window for preparation is narrowing. The differentiating factor is how systematically and urgently each player approaches the challenge — and by Carter's assessment, Ethereum is currently setting the pace.
