AI Reduces Quantum Attack Costs on Bitcoin by 86%

How much does it really cost today to try to break Bitcoin's encryption with a quantum computer? The answer has changed in recent weeks, and not for the better for those concerned with security. A new study shows that AI drastically reduces Bitcoin quantum attacks: a key benchmark for this type of attack has dropped by 86% in just two months, thanks to the combined efforts of over a hundred researchers and artificial intelligence agents.

Key Points

• The benchmark for a crucial step in a quantum attack on Bitcoin and Ethereum has dropped from 10.75 billion to 1.496 billion operations, an 86% reduction in two months.
• The research involved over 100 people from organizations such as Eigen Labs, Trail of Bits, StarkWare, Theta Labs, MultiVM Labs, and the Ethereum Foundation.
• The paper was published this week, although the reduction work was completed between late May and July 26.
• Bitcoin reserves on Binance have reached a two-year high of about 693,000 BTC, accounting for about 30% of the reserves of major exchanges.
• Bitcoin ETFs have recorded $283 million in net outflows, while Ethereum ETFs have lost $30 million.

How AI Reduces Quantum Attacks on Bitcoin: The Mechanism Explained

To understand why this number matters, we need to start from the technical basis. Bitcoin and Ethereum protect digital signatures with secp256k1, an elliptic curve. In theory, a sufficiently powerful quantum computer could reverse that mathematics and derive a private key from a public one. This is exactly the scenario that the research attempted to measure, not to realize.

The ECDSA.Fail Competition and the Numbers of Cryptography

The competition that produced these results is called ECDSA.Fail and is organized by Eigen Labs. The evaluation mechanism multiplies two parameters: the logical qubits required and the Toffoli gates, a particularly resource-intensive quantum operation. The lower the score, the fewer resources are needed to theoretically complete the attack. The most efficient project used 1,151 logical qubits and about 1.3 million Toffoli gates; a subsequent proposal pushed the number of gates below one million. For comparison, this score is about half of the benchmark published by Google Quantum AI in March, although the two counting methods are not directly comparable.

Who Worked on the Project and with What Method

The paper documenting the reduction is signed by researchers from Eigen Labs, Trail of Bits, StarkWare, Theta Labs, MultiVM Labs, and the Ethereum Foundation: essentially the establishment of crypto security that funds and publishes work that, in effect, makes the attack cheaper. The logic behind this choice is simple: knowing the real cost of an attack is the only way to plan a credible defense. The method used has been called Open Autoresearch, a process in which humans and AI agents iterate together on a shared measurable goal, with a verification system that checks every step.

What Changes for the Quantum Security of Bitcoin and Ethereum

This news fits into a race that has been ongoing for weeks on multiple fronts, putting pressure on deadlines that until now were considered ample. The reduction in attack costs comes as the entire sector is trying to secure its infrastructures before the threat becomes concrete.

Ethereum's 2029 Deadline and the Race for Quantum-Safe Defenses

The Ethereum Foundation has set a precise deadline: December 2029 to make transactions, validators, and storage resistant to quantum attacks. StarkWare has already brought the first quantum-safe Bitcoin transaction to the mainnet, while Ethereum developers have proposed to rebuild the validator deposit contract. Ripple is also strengthening the security of the XRP Ledger. The problem, as the research succinctly summarizes, is that the defense side is working on a fixed timeline measured in years, while the attack side has just gained 86% efficiency in two months thanks to about a hundred people focusing AI agents on the problem. This is not a prediction about the so-called Q-Day, and no funds are at risk today, but it is the first concrete evidence that research on attacks may not move at a human pace anymore.

Sector Investments in Quantum Resistance

The capital movement towards quantum resistance confirms how much this issue has become a priority. Galaxy committed up to $5 million in July, while nine companies, including BlackRock, Coinbase, and Strategy, have pledged $15 million over three years for quantum-safe blockchain technologies. Researchers also cite a draft from NIST proposing to phase out classical public-key cryptographic algorithms at the 112-bit level after 2030, and then ban them altogether after 2035. The picture that emerges is one of a sector racing to anticipate a problem that, until recently, seemed relegated to a distant future.

Crypto Market: Binance Reserves at Record Highs and ETF Outflows

While research on quantum security captures developers' attention, the market tells a parallel story of falling prices and moving capital. The two fronts are not directly connected, but coexist in the same moment of uncertainty.

Binance's Bitcoin Reserves at Two-Year Highs

Binance's Bitcoin reserves have surpassed 693,000 BTC, a two-year high representing about 30% of the total reserves of major exchanges. This data comes after about 77,000 BTC flowed onto the platform since the end of April. At the same time, Bitcoin ETFs recorded $283 million in net outflows, while Ethereum ETFs lost $30 million.

Regulation and Legal Front: Clarity Act and the Bankman-Fried Case

On the regulatory front, Republican senators have released a revised version of the Clarity Act, a 630-page document, ahead of the procedural vote on September 15. The revision introduces a registration requirement with the CFTC for protocols defined as "decentralized only in name," leaving the ethical provisions largely unchanged. Legally, Sam Bankman-Fried has filed an appeal with the U.S. Supreme Court to overturn his fraud conviction, claiming he was prevented from demonstrating that customers did not lose money and calling the confiscation of $11 billion excessive. On the technical side, Ethereum developers have tentatively set October 6 for the launch of the Glamsterdam upgrade on the Sepolia testnet, although the upgrade has not yet functioned stably on any private devnet and there are no dates set for Hoodi or the mainnet.

Frequently Asked Questions

How much have AI agents reduced the cost of a quantum attack on Bitcoin and Ethereum?

AI agents have reduced the benchmark for a quantum attack by 86%, lowering it from $10.75 billion to $1.496 billion in two months.

Who conducted the research on quantum attacks on Bitcoin and Ethereum?

The research involved over 100 individuals from organizations such as Eigen Labs, Trail of Bits, StarkWare, Theta Labs, MultiVM Labs, and the Ethereum Foundation.

What are the implications of the reduced quantum attack costs for the security of Bitcoin and Ethereum?

The reduction in attack costs makes it more urgent to develop defenses resistant to quantum computing, especially since Ethereum has set a deadline of 2029 to make transactions and storage quantum-resistant.

What market trends have emerged alongside the news of quantum research?

Bitcoin reserves on Binance have reached a two-year high of approximately 693,000 BTC, while Bitcoin and Ethereum ETFs have experienced significant outflows of $283 million and $30 million, respectively.
