A reported G7 quantum warning is putting fresh pressure on Bitcoin, Ethereum, exchanges, and custodians to prepare for post-quantum cryptography. The threat is real, but the headline claim itself isn’t verified here—so no panic, just overdue planning.

Stanford cryptographer Dan Boneh says quantum computing may threaten Bitcoin and Ethereum sooner than many expect, potentially weakening the signatures that secure wallets and transactions. The chains aren’t broken today — but post-quantum upgrades may need to start now, not later.

NEAR Protocol’s 2.13 upgrade brings post-quantum signing to mainnet with NIST-approved ML-DSA, aiming to harden account security against future quantum threats. The upgrade also adds dynamic resharding, signaling a serious push toward scalable, long-term infrastructure.

Bitcoin security groups are pushing AI labs for controlled frontier access so vetted defenders can outpace attackers already using local models, phishing tools, and automated recon. The ask is narrow, but the message is blunt: give good guys better tools before the bad guys do.

Anthropic says Claude found a serious flaw in HAWK, a post-quantum signature candidate, trimming its security margin but not affecting Bitcoin or Ethereum. The bigger takeaway: AI is becoming a real cryptanalysis tool, and Bitcoin’s post-quantum migration is getting harder to ignore.

Samson Mow says Bitcoin shouldn’t rush into post-quantum signatures, warning that a premature upgrade could create more immediate vulnerabilities than quantum computers ever do. Anthropic’s new AI crypto research adds urgency — and a healthy dose of caution.

Anthropic says its AI model found new attacks on weakened cryptographic systems, highlighting how frontier AI could complicate Bitcoin’s long-term move away from ECDSA. No, Bitcoin isn’t breaking today — but post-quantum planning just got another headache.

Coinbase says quantum computing isn’t an immediate threat to Bitcoin, but it’s pushing the industry to prepare anyway. A new Bitcoin Security Consortium will coordinate post-quantum planning, from protocol research to stronger key management, before the problem stops being theoretical.

Coinbase CEO Brian Armstrong says quantum computing is a real long-term threat to Bitcoin’s cryptography, not sci-fi hype, and Coinbase is preparing for post-quantum security now. The risk isn’t an instant network collapse — but waiting until the last minute could be a clown show.

BIP-361 puts Bitcoin’s quantum dilemma on a clock, proposing a staged move to quantum-safe wallet security before today’s signature schemes become a real target. The plan aims to reduce future theft risk, but it also raises ugly questions about coordination, deadlines, and old coins.
