StarkWare spent 10,000 satoshis from a lock built on hash-based signatures, in a Bitcoin transaction mined by MARA Pool. A flaw in the original script, which left one of two signature rounds unenforced, was fixed on October 7.
Poseidon was designed to be cheap inside zero-knowledge proofs. Justin Drake attributed the switch to faster proof systems for standard hashes. The hash-based design that used Poseidon has not been deployed on Ethereum.
The insurer's researchers put the code-breaking machine at roughly 1,250–1,450 logical qubits, against 4,700–7,500 for leading financial applications. The Google researchers they listed as a source reported fewer than 1,200 at one trade-off point.
Seventy-one percent of responding institutions had neither conducted nor planned a test of post-quantum cryptography. The HKMA framed its 2030 goal as an aim for the whole sector and listed four first steps banks can take now.
Managing Director Chia Der Jiun said MAS will issue supervisory expectations later in 2026, with progressive timelines for cryptographic inventories, migration priorities, and the capabilities to migrate. MAS published a consultation paper with proposed timelines on November 6.
EY said the machine will handle sensitive work such as fraud detection and risk management. Its chief innovation officer said the immediate value is not in replacing classical computing and named post-quantum readiness as the near-term focus.
Executive Order 14412 set December 2030 and December 2031 post-quantum deadlines for federal agencies, and NSA dates bind national security systems. Outside those systems, the measures reviewed here would date a company's duty through a FAR rule not yet proposed.
Regulators in five countries have acted or warned against products sold on the word "quantum." Generic claims about real technology get case-by-case scrutiny at most. Companies with real results face the same independent tests as everyone else.
McKinsey built the range from expert interviews and 2035 baselines for seven finance segments. It footnoted the use cases' impact levers as the impact of quantum computing and AI. McKinsey also called its value estimates approximate.
Xuhui's incubation zone launched with 26 companies, and Zhangjiang Quantum Bay with three platforms and four first tenants, state media reported. The same reports said both districts' dedicated quantum support policies were still in preparation.
