Post-quantum cryptography covers cryptographic algorithms, such as ML-KEM and ML-DSA, designed to remain secure against attacks from quantum computers.
a16z crypto researchers say Aerie aggregated 32,768 Falcon signatures in 0.65 seconds on a laptop, 29 times faster than leanVM on consensus signatures. Ethereum, which targets full quantum resistance by December 2029, has not committed to adopting it.

Anthropic published two Claude Mythos cryptanalysis results on July 28, 2026, including a key-recovery attack that roughly halves HAWK's security. According to a July 29, 2026 blog post, HAWK is a proposed post-quantum signature scheme, and the companion AES result trims an old attack on a weakened cipher and leaves deployed AES as it was.

Nine crypto companies launched the Quantum Alliance, which estimates that 6.4 million bitcoin, or 30.2% of supply, have public keys already exposed. Executives quoted by coindesk.com split on a 2028 arrival date and on whether to freeze vulnerable coins.

Google Quantum AI says magic state cultivation cut errors about 40x on its Willow chip, in a result published in Science. The up-to-95% overhead figure is an older estimate, and Google says the protocol still needs a larger-scale demonstration.

Starknet opened a seven-day nonbinding vote on October 15 asking STRK holders to back research into becoming a quantum-resistant Layer 1. A yes buys developer time and further votes, so the cost lands before any design exists.

Microsoft Research says Magnetar proves Rust, Go and C programs 10 to 39 times faster on average than the prior fastest comparable systems. It also says the security rests only on standard hash functions, where it says other fast systems took on stronger assumptions.

KPMG's survey of 400 US CEOs finds 85% expect cybercrime to affect their prosperity, more than say so of inflation or geopolitics. The firm that ran it sells cyber defense work, and its chair calls the risk in decades-old systems a multi-billion dollar opportunity.

Zcash fell 11% in 24 hours to an $18.5 billion market cap, per Decrypt data, after a 460% run from its March lows. Liquidated longs came to $17.9 million, under 1% of the roughly $2.3 billion lost, so leverage alone cannot account for the fall.

Coinbase, which says it custodies roughly 5% of all bitcoin, argues a new signature algorithm will not make the network quantum-resistant. Its list adds dormant coins, block space, MPC custody and full-node validation, and it wants work to start now.
Reality
Coinbase, which says it custodies about 5% of all bitcoin, warned on October 13 that a quantum-resistant upgrade could take years. It backs BIP-360, P2TRv2 and hybrid wallets now and wants dormant and lost coins settled separately.

IonQ agreed to buy cybersecurity firm Elisity for up to $1.3 billion in stock, including up to $150 million in earn-outs. IonQ says the purchase opens enterprise and government channels for its quantum offerings.

Starknet's builders are weighing a standalone L1 aimed at a quantum-resistant network in 2027, Bankless reported. StarkWare's June 30 roadmap had no L1 option, and its third phase depends on Ethereum.

Vitalik Buterin said on X on Oct. 7 that AI progress in mathematics could weaken lattice schemes ML-DSA and Falcon within two years. He suggested raising lattice key sizes tenfold to protect encryption outside blockchains.

AWS says teams can sign binaries, container images and SBOMs with ML-DSA today, using KMS, Private CA and IAM Roles Anywhere. CNSA 2.0 mandates exclusive quantum-resistant software signatures by 2030, and AWS dates the EU CRA's full effect to December 2027.

Starknet says it is actively considering leaving Ethereum to become its own L1, with 2027 as its target for full quantum resistance. STRK rose about 20% to $0.073, Decrypt reported, so holders are already paying for an exit that is still only under discussion.

Charles Hoskinson said on Oct. 9 that Vitalik Buterin's AI warning could slow the lattice-based protections NIST standardized in 2024. Ethereum is the one project the sources show moving away from lattices, so the test is whether anyone else follows.

Starknet's STRK token gained about 322% in 30 days to October 12 on a proposal to leave Ethereum, while its DeFi total value locked rose 5% to 7%. The market cap now sits at several times that locked value.

Ethereum Foundation researcher Justin Drake says AI could break ECDSA in "months not years" and wants large holders on fresh addresses now. Custodians would bear most of the cost, and his evidence is a single AI math result.

Zakura, a Zcash full-node builder, expects opcodes for hash-based signatures on transparent payments to land in Zcash in January. No date has been confirmed for switching them on across the network, so January is when the code arrives and the protection date is still open.

The Pentagon is committing about $350 million to quantum computing aimed at military logistics, advanced materials and next-generation weapons. For vendors, the related money with a stated purpose so far pays to build quantum hardware.
