Odaily reports: Nine blockchain organizations announced on Thursday the formation of the Quantum Alliance, aimed at developing "quantum-ready" standards and establishing unified testing and validation methods for the quantum resilience of networks, wallets, and infrastructure.The Quantum Alliance operates by reference to the Internet Engineering Task Force (IETF), with founding participants spanning underlying protocols, privacy networks, Rollups, hardware wallets, and security auditing, including Quantus, Postquant Labs, Midnight Foundation, Keystone, Abelian, and Hacken. Its work is divided into four groups: blockchain migration, post-quantum zero-knowledge systems, wallet security, and cross-chain compatibility.The Quantum Alliance stated that elliptic curve signatures leave approximately 6.04 million BTC, about 30% of the total supply, exposed to quantum risk. If a sufficiently capable quantum computer runs Shor's algorithm, it could theoretically reverse-engineer private keys and take control of the related assets.Citing multiple forecasts, the Quantum Alliance said the relevant risk window may lie in the late 2020s, with one model marking March 2028 as an earlier window; a Google Quantum AI study lowered its estimate of the number of qubits needed to break Bitcoin's cryptography to fewer than 500,000.

Odaily reports: “AI Stock God” Leopold Aschenbrenner’s fund Situational Awareness will disclose its equity holdings as of the end of the third quarter on November 16, covering the period from July 1 to September 30. The fund is said to have achieved a 439% return in the first half of this year, mainly by betting on SanDisk (SNDK) and Micron (MU) and using about 4x leverage. However, during the AI concept stock decline in July, its portfolio is said to have fallen by about 67% at one point, after which it sold the related stocks, and Citadel is said to have bought a considerable portion of them. In addition, Situational Awareness has also bought stocks including AMD, Bloom Energy (BE), CoreWeave (CRWV), and SanDisk, involving an amount of about $315 million.

Odaily reports: Solana has gone two consecutive years without reporting a mainnet outage. A report from Fidelity's Applied Technology Center (FCAT) notes that its network health has made progress across resilience, economic security, and performance metrics.The report notes that higher staking participation and incentive mechanisms rewarding validator performance underpin Solana's economic security, while low latency, improved scalability, and low-cost transactions also support its adoption at scale.The report also states that staking concentration among a small number of validator identities and operators, as well as concentration in custody and client software, still require continued observation. Jacob Creech, VP of Technology at the Solana Foundation, said that Solana reduced slot times to 350 milliseconds on August 21; the foundation announced plans in June to further reduce this to 200 milliseconds, with three additional 50-millisecond adjustments to follow.
