Une discussion sur les réseaux sociaux a émergé concernant les conséquences potentielles d'une attaque quantique contre le portefeuille de Satoshi Nakamoto, qui contient 1 million de BTC. Le YouTuber Josh Otten a imaginé un scénario où ces bitcoins seraient vendus, provoquant un effondrement du prix jusqu'à 3 dollars. Willy Woo, un investisseur de longue date, estime que les anciens de Bitcoin (OGs) achèteraient cette chute brutale et que le réseau survivrait. Environ 4 millions de BTC, dont ceux de Satoshi, sont détenus dans des adresses "pay-to-public-key" (P2PK) qui exposent la clé publique sur la blockchain lors d'une transaction, les rendant vulnérables. Les adresses plus récentes, qui ne divulguent pas la clé publique, sont bien moins à risque. La communauté reste divisée sur la menace quantique. Adam Back, co-fondateur de Blockstream, estime que cette menace est à 20-40 ans, laissant amplement le temps d'adopter des standards cryptographiques post-quantiques. L'analyste James Check ajoute que la plus grande menace est pour le prix du marché, car la communauté ne gèlerait pas les coins de Satoshi avant une attaque.

Un débat a éclaté sur les réseaux sociaux samedi concernant les effets potentiels d'un ordinateur quantique piratant le trésor de Bitcoin (BTC) de Satoshi Nakamoto et déversant ensuite ces coins sur le marché.

Le débat a commencé lorsque le YouTuber Josh Otten a partagé un graphique de prix du BTC s'effondrant à 3,00 $, affirmant que cela pourrait se produire si un ordinateur quantique suffisamment puissant émergeait et volait le million de BTC du créateur pseudonyme de Bitcoin, Satoshi Nakamoto, pour les vendre.

« De nombreux vétérans (OGs) achèteraient lors du krach éclair. Le réseau Bitcoin survivrait ; la plupart des coins ne sont pas immédiatement vulnérables », a déclaré Willy Woo, détenteur de Bitcoin de longue date.

Cependant, il y a environ 4 millions de BTC détenus dans des adresses de type « pay-to-public-key » (P2PK), y compris les coins de Satoshi, qui affichent la clé publique complète sur la blockchain lorsque les coins sont dépensés, les rendant vulnérables aux attaques quantiques, a ajouté Woo.

Exposer la clé publique complète d'un portefeuille Bitcoin sur la blockchain expose ces portefeuilles à des attaques quantiques à l'avenir, car un ordinateur quantique suffisamment puissant pourrait théoriquement dériver la clé privée de la clé publique.

Les types d'adresses de portefeuille BTC plus récents ne sont pas aussi vulnérables aux attaques quantiques car ils n'affichent pas les clés publiques complètes sur la blockchain, et si la clé publique n'est pas connue, un ordinateur quantique ne peut pas générer la clé privée associée à partir de ces données.

Les communautés Bitcoin et crypto continuent de débattre des effets potentiels de l'informatique quantique sur Bitcoin et la technologie de chiffrement qui sous-tend les cryptomonnaies, certains affirmant que l'informatique quantique signera la mort de l'industrie.

Adam Back, vétéran du Bitcoin, affirme que la menace des ordinateurs quantiques est à des décennies

Adam Back, détenteur précoce de Bitcoin, cypherpunk et co-fondateur de la société de technologie Bitcoin Blockstream, a déclaré que le BTC ne fera pas face à une menace quantique dans les 20 à 40 prochaines années.

Back a soutenu qu'il y avait amplement de temps pour adopter des normes cryptographiques post-quantiques, qui existent déjà, avant qu'un ordinateur quantique suffisamment puissant pour craquer le chiffrement moderne et les normes de cybersécurité ne soit construit.

L'analyste de marché James Check a déclaré que l'informatique quantique ne menace pas la technologie de Bitcoin car les utilisateurs migreront vers des adresses résistantes au quantique au moment où un ordinateur quantique viable émergera.

La menace quantique représente davantage une menace pour le prix de marché du Bitcoin car il n'y a « aucune chance » que la communauté Bitcoin accepte de geler les coins de Satoshi avant qu'un ordinateur quantique ne pirate ses portefeuilles et ne remette les coins en circulation, a déclaré Check.

U.S. Private Sector Job Growth Misses Expectations! July ADP Employment Rises by Only 44,000, Lowest This Year, Friday's Non-Farm Payrolls Data Becomes Key

US Private Payrolls in July rose by only 44,000, falling short of expectations and marking the slowest growth so far this year, according to the ADP National Employment Report. The figure was significantly below the 65,000 forecast by economists and sharply lower than the revised 95,000 jobs added in June. The report indicates a potential cooling in the labor market's momentum. However, wage growth for job-changers accelerated to its strongest pace in nearly a year, showing continued resilience in pay pressures. ADP Chief Economist Nela Richardson noted a shift in hiring patterns, with employers adjusting to a changing macroeconomic backdrop. The much-anticipated official US nonfarm payrolls report due on Friday will be key in confirming this trend. Should the data align, the current employment conditions would support the Federal Reserve's continued focus on combating persistently high inflation.

Bitwise CIO: What Happens to the Crypto Market if the CLARITY Act Fails This Week?

Title: What Happens to Crypto Markets if the CLARITY Act Fails This Week? – Insights from Bitwise CIO If the CLARITY Act fails to pass the U.S. Senate before its August recess, it will enter a "zombie state," lingering with low passage odds and prolonging institutional investor uncertainty. However, the crypto industry will continue advancing regardless. SEC Chair Paul Atkins has indicated the SEC is prepared to issue rules addressing the same issues as the CLARITY Act, potentially offering a more innovation-friendly path in the short term. The industry's momentum is now irreversible: major financial institutions are adopting crypto and blockchain technology, global jurisdictions are passing supportive laws, and financial activity is rapidly moving on-chain. While congressional delay is frustrating, history shows that such policy lags (like with the 1990s telecom bills) do not halt technological progress. Crypto has already become an integral part of the global financial infrastructure and will continue reshaping finance for decades, irrespective of Washington's immediate legislative outcomes.

Robinhood's Bigger Basket

"Robinhood's Bigger Basket" A few weeks ago, the author described Robinhood as a financial supermarket, bundling services from stocks to crypto. After watching the Q2 2026 earnings call, this view was seen as an understatement. The real power is not just attracting new customers, but making existing users engage more deeply. Key performance highlights: * Revenue surpassed $5B annualized, faster than legacy brokers like Charles Schwab. * Paying users grew 7% YoY to 28.4M, but Average Revenue Per User (ARPU) surged 24% to $187. * User activity intensified: per-user stock notional volume rose 56% and options contracts rose 43%, while the number of users trading these assets grew much slower (13% and 3% respectively). The Robinhood Gold subscription is a critical engine. Nearly half of new users sign up for Gold, which then acts as a gateway. Gold users hold 4.2x more assets and are 3.1x more likely to use retirement products than regular users. This creates a powerful cross-sell flywheel where using one product (e.g., prediction markets) increases adoption of others (e.g., IRAs). The future catalysts are Robinhood Chain and the upcoming Robinhood Social feed. * **Robinhood Chain** integrates services (tokenized stocks, lending, perpetuals) into a single, composable platform, reducing friction for cross-product usage. * **Robinhood Social** will internalize the trading idea generation process. Verified portfolios within the app could build trust and move the entire "idea-to-execution" loop inside Robinhood. Together, these act as neutral layers that drive engagement and value accumulation across Robinhood's ecosystem, similar to how Costco's store layout drives membership sales. Despite cyclical concerns in areas like crypto trading, Robinhood's diversified portfolio of 13 business lines each with over $100M in Annual Recurring Revenue (ARR) creates stability. Different product cycles offset each other within a single user's account. The company's unique advantage is transforming a single customer relationship into a compounding, self-diversifying revenue node spanning traditional and crypto finance, amplified by its native blockchain.

Crypto whales accumulate as bear market nears late stage: CryptoQuant

According to CryptoQuant, large cryptocurrency holders, or "whales," are accumulating Bitcoin and Ethereum as valuations suggest the market is entering the final stage of a bear market. The analytics firm reports that Bitcoin whale holdings, excluding exchanges and mining pools, increased from 2.87 million to 3.06 million BTC between December 2025 and June, with accumulation accelerating after Bitcoin's price fell below $60,000. Similarly, large Ethereum wallets have reached record holdings. The report points to on-chain metrics like realized price—Bitcoin is currently above it, while Ethereum is below—as potential indicators the market is approaching a bottom. The pattern of whales accumulating during price weakness has historically preceded market recoveries, though further downside risk remains. This analysis aligns with other research suggesting possible bottoming signals for Bitcoin.

Germany's Decades-Long Lead Lost as China's Machine Tools Quietly Rise to Global No.1

For decades, Germany held the top spot in global machine tool exports, but in 2025, China officially surpassed it for the first time, with its export value reaching 21% of the global market share. This article explores how China transformed from a heavily import-dependent nation to an export leader in this foundational industry for modern manufacturing. It begins by explaining the immense technical challenges in building high-end machine tools. Precision machining faces persistent physical obstacles like thermal expansion, vibration, and component wear, demanding top-tier core components like spindles, ball screws, and CNC systems. Historically, China relied on imports for over 90% of these critical components, and domestic machine tools suffered from short lifespans between failures (MTBF), making them unreliable for industrial use. The article credits the state-backed "04 Special Project" (2009-2020) for laying a crucial foundation. It boosted the market share of domestic high-end CNC systems from below 1% to nearly 32% and significantly improved overall machine reliability. However, the primary driver for China's rise was the massive and fast-evolving domestic market, particularly in the new-energy vehicle (NEV) sector. This created unique, high-demand applications like machining large integrated die-castings and complex battery housings. Domestic manufacturers, being close to the world's largest NEV market, rapidly iterated products to meet these new needs, gaining an edge over foreign competitors in certain emerging segments. Despite reaching the top spot in export value, the article stresses this is just a beginning. The current exports are often in specific categories like special-purpose processing machines (e.g., laser, EDM), with key markets in Asia and emerging economies. Furthermore, part of the "Chinese" export volume comes from foreign-owned factories within China. The true test for China's machine tool industry will be building the global trust and service infrastructure required for long-term, reliable operation overseas. The journey from being a buyer restricted by others' export controls to becoming a seller who must manage sensitive equipment exports and build a global support network has just entered a new, more demanding phase.
