Quantum computing threat to Bitcoin accelerates as AI advances, Stanford cryptographer warns against rushed fixes

May 24, 2026

As AI accelerates the development of quantum computers, the threat to Bitcoin's encryption is growing. Stanford cryptographer Dan Boneh warns a rushed migration to post-quantum security could cause a "catastrophic bug" and is a greater risk than an imminent attack. The debate follows a Google paper lowering the resources needed to break Bitcoin's cryptography, intensifying discussions around proposals to protect vulnerable wallets.

Quantum computing threat to Bitcoin

▪A sufficiently powerful quantum computer could theoretically derive private keys from public keys, compromising vulnerable wallets on blockchain networks.
▪As of March 1, 2026, over 34% of all bitcoin had an exposed public key on-chain, leaving those funds theoretically vulnerable to a quantum attack.
▪A March 2026 Google Quantum AI whitepaper estimated that breaking Bitcoin's secp256k1 encryption could require as few as 1,200 logical qubits.
▪Stanford cryptographer Dan Boneh views a cryptographically relevant quantum computer as possible but unlikely before 2035 at current funding levels.

AI acceleration of quantum development

▪Machine learning systems are being used to optimize quantum error correction, one of the field's major engineering bottlenecks.
▪Illia Polosukhin, co-founder of NEAR Protocol, stated that AI is an accelerator for scientific research, leading to progress earlier than expected.
▪Researchers believe artificial intelligence may be accelerating the development timeline for quantum computing.

Harvest now, decrypt later attacks

▪The strategy of collecting encrypted data for future decryption with more powerful computers is known as “harvest now, decrypt later.”
▪Security researchers are concerned that adversaries are collecting encrypted data today to decrypt it in the future with quantum computers.

Post-quantum cryptography migration strategies

▪A lawsuit was filed in New York by a plaintiff called "Noah Doe" seeking ownership of 3.7 million BTC in dormant wallets, arguing they are abandoned property.
▪Dan Boneh stated that aggressively moving Bitcoin to a post-quantum architecture by 2029 would be a "mistake."
▪Stanford cryptographer Dan Boneh warned that a rushed transition to post-quantum cryptography is more likely to cause a "catastrophic bug" than a quantum attack.
▪A draft proposal, BIP-361, would freeze quantum-vulnerable Bitcoin addresses and phase out legacy signature types over a multi-year timeline.

AI-driven security arms race

▪AI is being used by attackers to find software vulnerabilities, while defenders use it for code auditing and formal verification.
▪Alex Pruden, CEO of Project Eleven, stated that security can no longer be treated as static infrastructure that is upgraded only once a decade.
▪Researchers argue that the combination of AI and quantum computing is creating a permanent security arms race.
