The Ethereum Foundation Spent Eight Years on a Hash Its Roadmap No Longer Needs
Binary-field proof systems made standard hashes cheap enough to prove that Ethereum's exotic one lost its reason to exist. Nobody broke it. An eight-year research bet was retired in a single post.

Google Cloud Put Dates on Its PQC Migration. Signatures Trail Confidentiality by a Year.
Google Cloud has attached target years to 19 service-level roadmap entries running through 2029. Store-now-decrypt-later mitigation is due in 2027, signatures and key-management foundations in 2028.

A New Classic McEliece Distinguisher Undercuts Generic Decoding. It Is Not a Break.
No security claim has fallen and the scheme is not broken. What fell is the quantitative argument that made structural attacks easy to set aside, because one now costs less than generic decoding on every NIST parameter set.

Two QFT Records in Four Months. Neither Gets You Closer to Breaking RSA.
Two compilation teams claimed the largest quantum Fourier transform ever run, four months apart, on the same IBM chip. Their circuits and metrics are not comparable, and the gate counts explain why.

A Peer-Reviewed CRYPTO 2026 Paper Just Gave ML-KEM’s Foundation a New Quantum Target
Wen and Zheng prove Module-LWE quantum-polynomially equivalent to a structured dihedral problem and reduce it to EDCP. The result maps ML-KEM's mathematical foundation into territory three research groups are actively probing with quantum algorithms.

Daniel Simon Claims a Polynomial-Time Quantum Algorithm for Lattice Problems. And a CRYPTO 2026 Paper Connects It to ML-KEM
Daniel Simon has posted a preliminary polynomial-time algorithm for the Dihedral Coset Problem, and a peer-reviewed CRYPTO 2026 result supplies the Module-LWE link. Neither one breaks ML-KEM. Together they change the risk conversation.

Allianz Quantum Risk Report Gets the Capital Thesis Right and the Cryptanalysis Wrong
Allianz Research published a technically serious quantum risk assessment for finance. Its capital-flow analysis is unusually effective. Its cryptanalytic chart and threat model need corrections that matter for anyone using it to plan.

First External Operators Apply to Chrome’s Post-Quantum Certificate Test Program
TrustAsia filed the first known CA application for Chrome's Merkle Tree Certificate test root store. The filing implements two recently standardized mechanisms from the IETF PLANTS draft, adding concrete evidence that post-quantum web PKI infrastructure is moving from draft to deployment.

HKMA Gives Hong Kong Banks a 2.3 Out of 10 on Quantum Readiness, Targets Full Migration by 2030
HKMA's first Quantum Preparedness Index scores Hong Kong's banking sector PQC readiness at 2.3 out of 10. Most respondents remain at an early stage, while the regulator targets full sectoral readiness by 2030.

87% of Organizations Are Pursuing PQC. Only 7% Have Deployed It.
DigiCert's second annual PQC survey finds at-scale certificate deployment barely moved in a year. The barrier profile now points to execution, not awareness, and that tells us more than the headline number.

Pure ML-KEM for TLS 1.3 Reaches IETF Last Call
The IESG is taking final comments on standalone ML-KEM key establishment for TLS 1.3 until August 13, after three Working Group Last Calls, a contested consensus determination, and a chairs' refusal to release the numbers behind it.

AI Broke a NIST Candidate. Not Your Encryption
Claude Mythos Preview recovered HAWK-256 challenge keys and improved a 13-year-old reduced-round AES result. ML-KEM, ML-DSA, SLH-DSA, Falcon, and production AES are untouched. The real shift is the cost of finding flaws.

Bitcoin’s Institutions Take On the Quantum Security Bill
Nine institutions pledged $15 million over three years for Bitcoin security, with quantum readiness the first workstream. Galaxy separately announced up to $5 million in developer grants for post-quantum work.

ECC Attack Circuit Drops to 835 Logical Qubits
The same Tsinghua-Peking group whose April preprint reached 1,333 qubits for a 256-bit ECC attack has pushed to 835, the lowest yet. The circuit is narrower, but the gate count is 20 times higher than the leading alternative. Smaller machine, longer run.
