Asi Alliance Can Rebuild Google’s Secret Quantum Circuit, Ceo Ben Goertzel Says

What Happened

That includes about 1.7 million coins from the network’s earliest years, as well as additional funds affected by address reuse and Bitcoin’s Taproot upgrade, which makes public keys visible by default.

Bitcoin currently has no coordinated upgrade roadmap to meet that deadline.

“Keeping Capabilities Secret Buys You at Most a Very Short Window”

We are confident that we could regenerate the ‘secret circuit’ Google found using our own expertise and reasonable compute, and if we can do it, the Chinese government and other well-resourced actors certainly can too. Keeping capabilities secret buys you at most a very short window.

But Google’s circuit, in his view, does not meet that bar because the knowledge to build it is already widely accessible to capable actors.

Why It Matters

Google’s March 30 whitepaper showed that two working circuits implementing Shor’s algorithm to break 256-bit elliptic curve cryptography could be built with fewer than 500,000 physical qubits. The team chose not to release the code and instead published a zero-knowledge proof. Goertzel told BeInCrypto that decision changes nothing.

The security benefits of decentralized scrutiny, he argued, outweigh the marginal risk reduction of secrecy when parallel discovery is the norm.

The Google whitepaper models what it calls an “on-spend attack.” A quantum computer could prepare part of the calculation in advance, then crack a Bitcoin (BTC) transaction in about nine minutes once the public key is exposed.

Goertzel told BeInCrypto that a 41% attack rate is not a borderline risk. It is a structural failure.

While much of the industry debated the implications, Goertzel told BeInCrypto his team saw this coming years ago.

He has previously predicted that human-level artificial general intelligence (AGI) could arrive around 2027 or 2028.

Details

Dr. Ben Goertzel, CEO of the Artificial Superintelligence (ASI) Alliance, told BeInCrypto his team can recreate the quantum attack circuits that Google Quantum AI built but refused to publish. He warned that if his organization can do it, nation-states already can too.

Google framed its decision to withhold the circuits as responsible disclosure. The blog post called it a deliberate departure from the team’s historical practice of full transparency, motivated by the potential for misuse.

The crypto industry largely debated whether this aligned with its founding principle of “don’t trust, verify.”

Goertzel did not share the concern. He told BeInCrypto the secrecy is functionally irrelevant.

He added that the ASI Alliance has not withheld any of its own code for safety reasons, though the team has discussed it internally. His default position is openness.

He did leave room for exceptions. If something posed a specific, acute, short-term danger, the team would hold it back.

The 41% Problem

Since Bitcoin’s average block confirmation takes 10 minutes, the attacker has a roughly 41% probability of finishing first.

The paper also estimates that roughly 6.9 million BTC are already held in wallets whose public keys have been exposed in some form.

Any attack success rate above single digits is deeply problematic for a store-of-value chain. Once rational actors believe there is a meaningful probability that a transaction can be reversed or an address drained during the confirmation window, the game-theoretic assurances that underpin Bitcoin’s security model collapse. At 41%, you are well past the threshold.

He noted that the hardware to execute such an attack does not yet exist. But the mathematical proof is complete, and Google has set a 2029 deadline for the industry to migrate to post-quantum cryptography (PQC).

ASI Alliance Says It Was Built for This

Google’s quantum timeline puts both breakthroughs on a collision course, and Goertzel said the ASI Alliance designed its infrastructure for exactly that convergence.
