Resumen

Шансы на победу в гонке по заработку цифровых валют определяет вычислительная мощность оборудования. Для этого параметра криптосообщество использует специальные обозначения. Терахеш ― это единица измерения, которая показывает, сколько времени требуется одному устройству для проверки транзакций в блоке. Фактор — основополагающий при определении прибыли.

Что такое терахеш

Для добычи цифровых валют нужно мощное оборудование. Его производительность измеряется в H/s. Терахеш — это триллион таких расчетов. Чем выше TH/s, тем больше комбинаций устройство генерирует за конкретный период времени. Некоторые майнеры увеличивают общую скорость хеширования, объединяясь в пул. Затем они делят награды в соответствии с вкладом TH.

Для чего нужен параметр

Вычислительная мощность ASIC измеряется в TH/s. Это главная характеристика при рассмотрении вопроса о покупке устройства и расчете прибыли. В октябре 2022 года популярные модели асиков вычисляют 110-200 TH/s, что намного превышает значения видеокарт.

Показатель также представляет вычислительную мощность сети. Например, в октябре 2022 года скорость хеширования RVN — 15,70 TH/s.

В каких единицах измеряется TH

Показатель эквивалентен 1 триллиону хешей в секунду. Помимо этого параметра, у оборудования есть значение эффективности, которое измеряется в джоулях (J/TH) или ваттах (W/TH) на терахеш.

Что влияет на уровень терахеша

При покупке ASIC в первую очередь смотрят на показатель TH/s. На его уровень влияют следующие факторы:

Количество устройств. Чем больше асиков, тем эффективнее майнинг.
Температура. Скорость работы снижается, если оборудование подвержено перегреву.
Тайминги. Это время, которое нужно устройству для выполнения команды. Асик перепрошивают, чтобы настроить показатель на максимальную эффективность.

Повышают уровень TH с помощью разгона. Например, у асика Antminer S19 Pro по умолчанию хешрейт составляет 110 TH/s. Его увеличивают до 150-180 TH/s, подключая блоки питания на 6 тыс. Вт или 8 тыс. Вт. Antminer S19 с 95 TH/s разгоняют до 125 TH/s, поменяв способ охлаждения.

Как узнать уровень TH

Чтобы определить показатель, можно посмотреть характеристики на странице производителя или загрузить ПО для майнинга и запустить тест на оборудовании. Еще один способ — воспользоваться специальными калькуляторами. Minerstat помогает узнать значение параметра и рассчитать прибыльность устройства.

При выборе оборудования значение TH и потребляемой мощности выставляются автоматически

Оптимальный TH в майнинге

Созданные хеши случайны, их невозможно предсказать. Потребуется много попыток, прежде чем блок будет добавлен в сеть. Значение TH/s в майнинге влияет на скорость обработки транзакций.

В октябре 2022 года хешрейт биткоина — 295 EH/s. Это означает, что за секунду создается 295 квинтиллионов уравнений. Чтобы узнать вероятность нахождения блока, нужно разделить собственный хешрейт на общий.

Хешрейт в криптовалюте

У каждого токена есть показатель общей вычислительной мощности, используемой для проверки транзакций в сети. Исходя из этого параметра майнеры решают, стоит ли им прилагать усилия в добыче криптовалюты. Также эта метрика важна для оценки безопасности.

Чем выше значение, тем сложнее злоумышленнику запустить атаку на блокчейн. Если хешрейт токена быстро снижается, криптоплатформы могут ограничить торговлю или исключить его из списка.

Anthropic Major Release: "The Founder's Playbook" - All 4 Stages of Entrepreneurship, Completely Reimagined with AI

**Anthropic Releases "The Founder's Playbook," Reimagining the Four Stages of Startups with AI** The logic of entrepreneurship is being fundamentally reshaped by AI. Anthropic's new handbook, "The Founder's Playbook: Building an AI-Native Startup," defines the AI-native startup as a new species: not a traditional company with AI tools, but a venture driven by AI from day one. The founder's role is transforming from a hands-on builder to a conductor or architect, orchestrating AI agents for execution while focusing on high-level judgment and strategy. Anthropic outlines a product matrix of Claude tools for different tasks: Claude Chat for interactive research, Claude Code for generating production-ready code, and Claude Cowork for automating knowledge-intensive workflows. The handbook structures the startup lifecycle into four stages, detailing core goals, pitfalls, and AI applications for each: 1. **Idea Stage**: Focuses on validating a real problem. The core challenge is avoiding confirmation bias. AI practices include using Claude as a "structured devil's advocate" to challenge assumptions and for automated market/competitor research. 2. **MVP Stage**: Aims to gather early signals of Product-Market Fit (PMF). Key risks are technical debt and scope creep due to rapid AI-assisted development. Recommended AI uses include maintaining project memory documents (e.g., CLAUDE.md), using Claude Code for structured coding, and automating user feedback analysis. 3. **Launch Stage**: Centers on establishing scalable growth, operations, and compliance. Challenges include accelerating technical debt and founders becoming bottlenecks. AI should be used to build an "operating system" for launch—automating routine tasks (scheduling, reporting, content) and code audits—freeing founders for critical decisions. 4. **Scale Stage**: Focuses on achieving sustainable business operations. The main challenge is delegating operational control. AI should be leveraged for differentiated marketing, operational optimization, and building competitive moats through data network effects. The handbook concludes that in the AI era, "Can we build it?" is no longer the primary constraint. The advantage shifts back to foundational strengths: **insight, judgment, and a deep understanding of a specific problem and audience.**

Eight Departments Launch Severe Crackdown on Cross-Border Securities Firms, How to Interpret This?

China's top financial regulators, including the CSRC and seven other ministries, have launched a sweeping crackdown on unlicensed cross-border securities operations. The core action involves a joint enforcement plan and the issuance of administrative penalties against major offshore internet brokers like Futu and Tiger Brokers for conducting unauthorized securities business in mainland China without a domestic license. The primary legal basis is China's requirement for securities businesses to operate with proper, locally issued licenses. The crackdown aims to eliminate a major regulatory gray area, plugging channels that allowed massive, unmonitored capital outflows which posed risks to financial stability, currency controls, and foreign exchange reserves. It also seeks to protect mainland investors who previously lacked legal recourse when dealing with offshore platforms and to secure sensitive financial data. The immediate impact is severe for the targeted brokers, including a complete ban on new mainland business, forced liquidation of existing mainland client positions over two years, and the confiscation of illegal profits estimated in the billions. Their U.S.-listed shares plummeted in response. Market analysts warn that the forced sell-off of an estimated 250-280 billion RMB in assets, concentrated in U.S. tech stocks, Chinese ADRs, and Hong Kong equities, could create sustained selling pressure on these markets over the next two years, potentially lowering valuations. For mainland investors, legal cross-border investment channels will become extremely constrained. The high asset threshold for the Stock Connect program and the severe shortage of QDII fund quotas—leading to chronic high premiums on popular U.S.-focused ETFs—mean retail access to overseas markets like the U.S. will be sharply limited. Conversely, some of the returning capital may flow into domestic A-share sectors like AI, semiconductors, and advanced manufacturing. However, this could further inflate valuations in these already elevated sectors. In conclusion, regulators frame this move not as closing off cross-border investment, but as a necessary step to enforce compliance, manage systemic risk, and steer investors toward regulated, protected channels like QDII and Stock Connect for the long-term health of the financial system.
