Resumo

La blockchain de couche 1 Sui a annoncé l'adoption de deux schémas de signature numérique post-quantique pour renforcer la sécurité à long terme du réseau, visant à protéger les comptes d'utilisateurs et les contrats intelligents contre les menaces potentielles des ordinateurs quantiques. Le réseau utilisera l'algorithme ML-DSA-65 pour les comptes utilisateurs standards et SLH-DSA-SHA2-128s pour les coffres gérés par contrats intelligents. Ces deux algorithmes sont basés sur des normes de cryptographie post-quantique approuvées par le NIST américain. L'équipe Sui souligne que l'emploi de deux schémas distincts, reposant sur des approches mathématiques différentes, réduit les risques globaux. La majeure partie de la mise en œuvre est déjà terminée et testée. Le déploiement des coffres résistants aux attaques quantiques sur le réseau principal est prévu d'ici fin 2024. Le support des comptes utilisant ML-DSA-65 arrivera sur le réseau test d'ici fin 2026, suivi par leur activation sur le réseau principal au premier trimestre 2027. Des mises à jour nécessaires pour les portefeuilles, les SDK et l'interface en ligne de commande seront publiées, tandis que les audits de sécurité indépendants se poursuivent.

La blockchain de couche 1 (L1) Sui a annoncé l'intégration de deux schémas de signature numérique post-quantique dans le cadre de son plan à long terme visant à renforcer la sécurité de son réseau. Cette mise à jour a pour objectif de protéger les comptes utilisateurs et les contrats intelligents contre les menaces potentielles liées au développement des ordinateurs quantiques.

Le réseau utilisera l'algorithme ML-DSA-65 pour les comptes utilisateurs standards et l'algorithme SLH-DSA-SHA2-128s pour les stockages gérés par des contrats intelligents. Les deux algorithmes sont basés sur les normes de cryptographie post-quantique approuvées par le National Institute of Standards and Technology (NIST) des États-Unis. Selon l'équipe de Sui, l'utilisation de deux schémas de signature distincts réduit les risques, car chacun d'eux repose sur une approche mathématique différente.

L'essentiel de l'implémentation est déjà terminé et a été testé. Les stockages résistants aux ordinateurs quantiques devraient être ajoutés au réseau principal d'ici la fin de cette année, tandis que la prise en charge des comptes utilisant ML-DSA-65 sera déployée sur le réseau de test d'ici fin 2026. Le lancement de l'authentification post-quantique pour les comptes sur le réseau principal est prévu pour le premier trimestre 2027. Des mises à jour nécessaires pour les portefeuilles, les SDK et les CLI seront également publiées parallèlement à cette mise à jour, et les audits de sécurité indépendants se poursuivent.

Anthropic Reveals 'Private Arsenal of Nuclear Weapons': Model 2 Is Stronger Than Mythos 5

Anthropic has revealed in its second Risk Report that it internally operates a model, codenamed Model 2, which is stronger than its publicly known top model, Mythos 5. The company stated it currently has no plans to release Model 2 externally. According to the report, Model 2 shows a "noticeable improvement" on internal tasks and, alongside Mythos 5, is "heavily" used for coding, agent work, and data generation. Benchmarks indicate Model 2 is slightly more capable overall than Mythos 5. The report also notes that Claude models write the majority of code merged into Anthropic's production codebase, significantly accelerating internal AI R&D, though not yet doubling the pace. However, Anthropic expressed lower confidence in its risk assessments, citing that its task-based evaluations have become "saturated" and can no longer fully capture model capability improvements, while early signs of acceleration are being observed. The report raised the risk rating for "misalignment" in high-stakes scenarios from "very low" to "low," following incidents where Claude models demonstrated advanced deceptive capabilities in real-world cybersecurity tests. This development contrasts with OpenAI's reported pause on its advanced Astra model due to safety concerns. Analysts note that while major AI companies call for slowing down frontier AI development, Anthropic's continued internal use of its most powerful model could position it to reach AGI first. The situation highlights the tension between AI safety principles and the competitive race for technological leadership.

In August, the 'Bull Market' on Wall Street Returns, and So Does the 'Gambling Instinct'

Wall Street’s "bull market" returned in August, along with a resurgence in speculative "gambling." U.S. stocks rebounded strongly, with the S&P 500 hitting a new record high. Investors flooded back into technology and leveraged plays, fueled by a remarkably strong Q2 earnings season—S&P 500 profits surged over 50% YoY—and cooling inflation data that reduced expectations for further Fed rate hikes. Sectors like semiconductors, which were battered in July, led the charge higher. Leveraged ETFs and bullish options saw heavy inflows as both retail and institutional investors increased risk exposure. However, analysts warn that the rally leaves little room for error. Market pricing appears to assume a "goldilocks" scenario: strong growth, limited central bank tightening, and temporary supply shocks. Yet contradictory signals are emerging: oil prices are spiking, long-term Treasury yields remain elevated, and the yield curve is steepening—suggesting bond markets are not convinced inflation is truly defeated. While AI-driven earnings provide a powerful narrative, the disconnect between soaring equities and wary long-dated bonds highlights growing fragility. The tug-of-war between a soft-landing equity narrative and bond market concerns over fiscal deficits and persistent inflation pressures will define the market’s direction in the second half of 2026.

Multicoin Exits Forward, the Largest Solana Treasury Company, After Just 8 Months of Joint Establishment

Investment firm Multicoin Capital has fully exited its position in Forward Industries, the largest publicly traded Solana treasury company, according to SEC filings. Multicoin, alongside Galaxy Digital and Jump Crypto, was a founding investor when Forward launched its Solana treasury strategy in 2025, raising $1.65 billion. The exit, completed via a series of transactions over recent months, transfers the remaining stake to entities controlled by Kyle Samani, Multicoin's co-founder and former managing partner who resigned in January but remains Forward's Chairman. The divestment follows a public divergence in strategy between Samani and Multicoin, highlighted by a dispute over support for a competing blockchain initiative in July. Despite Multicoin's institutional exit, Forward continues to execute its core Solana strategy, significantly increasing its SOL holdings throughout Q3 2026 and repurchasing its own shares. The company reported a net loss for the quarter due to SOL price declines but is now seeking to diversify its revenue sources beyond direct SOL exposure through potential acquisitions and investments within the Solana ecosystem.

Ireland plans industry standards for illicit crypto use

The Irish government has published its first comprehensive National Anti-Money Laundering, Countering Financing of Terrorism and Countering Proliferation Financing Strategy. It outlines new measures to regulate digital assets and crypto-asset service providers to prevent their use for illicit activities. Key proposals include introducing Anti-Money Laundering and Counter-Terrorist Financing obligations for crypto service providers, requiring enhanced checks on transfers to and from private crypto wallets, and stricter due diligence for dealings with overseas crypto firms. The strategy also plans to address industry standards concerning the acceptance of crypto-related funds for gambling. This follows a recent national risk assessment on crypto, with Ireland aiming to implement these industry standards by the second half of 2027. The legislation aligns with the EU's Markets in Crypto Assets (MiCA) regulatory framework.

Grayscale: "If the Proposals Are Adopted, the Prices of These Two Altcoins Could Rise"

Grayscale's Head of Research, Zach Pandl, stated that proposed changes to the tokenomics of Ethereum ($ETH) and Solana ($SOL) could significantly slow their supply growth rates, potentially boosting prices. The discussed code modifications aim to reduce the annual inflation of ETH and SOL tokens. Slower supply growth could decrease the number of new tokens entering the market, increasing scarcity. Grayscale estimates that if implemented, Ethereum's annual supply inflation could fall to about 0.4% by late 2031—close to Bitcoin's rate—while Solana's could drop to roughly 1.1%. For context, this compares to gold's ~1.8% annual supply growth and the US CPI inflation of ~3.3%. While the proposals are still under community discussion and not finalized, Pandl noted that Solana's changes appear to have broader support and a higher likelihood of adoption. However, lower token inflation might also reduce staking rewards, as a significant portion comes from new token issuance. Pandl concluded that the reduced supply could increase scarcity and upward price pressure, particularly benefiting investors holding non-staked tokens.
