Учёный вычислил, как дорого обойдётся атака 51% на биткоин

Профессор Школы бизнеса при Университете Дьюка из США Кэмпбелл Харви подсчитал, сколько будет стоить атака 51% на сеть биткоина.

По оценкам учёного, захват как минимум 51% вычислительной мощности сети BTC и её контроль на протяжении недели потребует примерно $6,07 млрд. Он включил в список расходов следующие пункты:

$4,6 млрд на оборудование для майнинга криптовалюты;
$1,34 млрд на строительство дата-центра;
$130 млн на электроэнергию.

Текущий уровень капитализации биткоина составляет $2,25 трлн, соответственно, для проведения атаки 51% необходимы инвестиции в размере всего лишь 0,26% от стоимости выпущенных монет. Поэтому, как полагает Харви, злоумышленники могут неплохо подзаработать, напав на блокчейн цифрового актива.

Для этого им нужно будет открыть короткие позиции на рынке фьючерсов на BTC незадолго до проведения атаки, в результате которой курс монеты рухнет.

Главная опасность, подстерегающая людей, отважившихся захватить под свой контроль сеть биткоина, кроется в раскрытии их плана. На создание такой мощной майнинговой фермы уйдёт несколько лет, и это вряд ли останется незамеченным, а открытие коротких позиций на очень крупную сумму сотрудники бирж могут посчитать подозрительным и заблокировать подобные операции.

В связи с этим президент добывающей BTC компании American Bitcoin Corp Мэтт Прусак не верит в реальность проведения атаки 51% на блокчейн криптовалюты и относится к выкладкам Кэмпбелла как к сугубо теоретическим.

DeXe hits new ATH, targets $40 – THESE 2 indicators back bulls

DeXe (DEXE) surged to a new all-time high of $35.5, currently trading around $34 with a 17.9% daily gain. The rally is supported by strong market participation, with trading volume jumping 161% to $128 million. Buyers have dominated the market for eight consecutive days, showing aggressive spot accumulation. Additionally, open interest rose 18% to $160 million, indicating active new positions in derivatives. Key technical indicators like the RSI (76) and the ADX (with +DI above ADX and -DI) suggest strong buying pressure and a solid uptrend. If demand persists and the $30 support holds, DEXE could target the $40 level.

Is Ethereum Truly a "World Computer"?

Title: Is Ethereum Really a "World Computer"? Ethereum, envisioned as a "world computer" by its founder Vitalik Buterin, aims to be a decentralized platform for global applications. However, a recent analysis by Four Pillars raises questions about whether it is more accurately a "Western computer," based on the geographical distribution of its validators. Currently, the United States dominates with 38.19% of all validators, followed by Germany at 13.04%. Combined, these two countries account for over half of the network. In contrast, Asian representation is minimal, with Singapore holding only 3.15%. The concentration is partly due to affordable cloud hosting services like Hetzner and OVH in Europe and North America, as well as the prevalence of residential validators in the U.S., where individuals run nodes via home internet connections. When examining professionally operated validators, the distribution becomes more balanced. The U.S. share drops to 25.81%, while Asian countries like Singapore (7.28%), Hong Kong (6.44%), Japan (6.38%), and South Korea (4.59%) collectively approach the U.S. level. This shift reflects strategic deployments by institutions to meet regulatory requirements and reduce latency for local users. However, regions like South America, the Middle East, and Africa remain underrepresented. Ethereum's peer-to-peer network mechanisms, such as gossipsub, disadvantage areas with low node density, creating a feedback loop where delayed message propagation reduces validator performance and rewards. This imbalance challenges Ethereum's promises of censorship resistance and global accessibility. Despite these issues, opportunities exist for growth in underrepresented regions. As demand for localized staking infrastructure rises, early entrants in areas like the Middle East could establish dominant positions by offering compliant, low-latency solutions. The evolving validator landscape highlights both the structural challenges and the potential for Ethereum to move closer to its "world computer" ideal.

Bittensor's Intellectual Arbitrage Trap: Capital Only Speculates on Tokens, Quality AI Goes Unpaid

The article critiques the inherent flaws in the Bittensor network's decentralized AI incentive model. While designed to use TAO tokens to reward AI development across specialized subnets (like model training or data crawling), the system prioritizes capital flow over genuine utility. A subnet's reward allocation is primarily determined by the price of its native Alpha token, creating a self-reinforcing loop where buying pressure begets more rewards, detached from the actual quality or real-world adoption of the AI services. Critical vulnerabilities are exposed: the scoring mechanism for AI outputs can be gamed if a majority of validators collude, and "score copying" among validators is possible. The network's value is anchored to speculative trading rather than verified user demand or revenue. Despite these issues, the author acknowledges Bittensor's potential to foster open, distributed AI infrastructure, similar to how past tech bubbles built lasting assets. The pending approval of Bittensor ETFs could bring both significant capital and necessary regulatory scrutiny, potentially forcing the ecosystem to mature and align incentives with tangible value creation.

‘Walled off’ – Hyperliquid, Phantom press CFTC for 3 DeFi demands

Hyperliquid and Solana-based wallet Phantom have urged the U.S. Commodity Futures Trading Commission (CFTC) to modernize regulations for decentralized finance (DeFi). In a letter, they made three key requests: first, that non-custodial software developers not be automatically treated as brokers or exchanges; second, that existing no-action relief for self-custodial wallets be formalized into guidance; and third, that the CFTC create a framework allowing regulated entities to use blockchain for trading and settlement. They argue these changes are necessary to prevent stifling innovation and pushing activity offshore. The request responds to a CFTC inquiry on barriers to fintech partnerships. Similar exemptions are under discussion in the proposed CLARITY Act. However, granting these requests could face legal challenges from traditional market participants like the Chicago Mercantile Exchange (CME), which has previously sued the CFTC over crypto product approvals. Traditional players argue DeFi platforms should meet the same regulatory standards as conventional exchanges. With the CLARITY Act's future uncertain, any CFTC action on DeFi exemptions may lead to further litigation.

Walsh Is Quietly Reshaping the Federal Reserve Through Five Working Groups

In an effort to subtly reshape the Federal Reserve, Chair Kevin Wash has established five "Chair's Advancement of Monetary Policy" working groups. These groups, led entirely by 15 external experts and supported by Fed staff, cover the entire monetary policy "operating system": data inputs, productivity/employment/inflation models, balance sheet tools, and external communications. The initiative centralizes agenda-setting, knowledge production, data access, and public narrative control under the Chair's office, while formal decision-making power remains with the FOMC and Board. Analysts note this mirrors tactics like China's use of central working groups—bypassing bureaucratic inertia, creating parallel reporting channels, and enabling rapid "top-level design" to reset policy agendas. This suggests Wash may hold off on major policy moves until the groups conclude their studies. Key future questions are whether these groups become permanent and if their conclusions effectively become pre-determined policy for the FOMC to ratify.
