@Herofire на самом деле я работаю на себя решение этой избыточности, используя набор примирения алгоритмы, чтобы найти различия между известными инвс, а не просто вещание их всех. Спасибо. Все эти разговоры о "аренда ближайший квартира на Уолл-Стрит из-за 10мс" заставило меня задуматься о производительности. И я пошел ждать на бизнес-день для сделки, чтобы пройти через я сделал это в пятницу вечером... Мне кажется, я нашел корень проблемы. ОП отредактированы. @PieterWuille мне действительно пришлось doublespend сделки несколько дней назад (БТД ядра был установлен с низкими сборами)... Спасибо за Ваш быстрый ответ. Да я имел в виду доказательство-Кола. Наилучшие Пожелания, Деклан ОП ищет услуги, которые поддерживают отправку биткоинов на HTTP(Ы) URL вместо того, чтобы войти в биткойн-адрес напрямую, так, ваш ответ, скорее, бесполезно. Нестандартные для узла segwit или segwit узел? Если узлы segwit рассмотреть такой сделки нестандартных, где это указано в документации?

Хэш-это 256 бит, так что есть 2^256 возможных хэшей в хэш-пространстве. Но если вы утверждаете, что хэш должен начинаться с 0, что уменьшает количество хэшей, которые разрешены (и, следовательно, удваивает среднее количество хэшей вам нужно проверить), и если вы говорите, что он должен начинаться с 0, Вот сейчас только четверть хэш-пространства, что является допустимым. Трудность нахождения валидного хэша, таким образом, растет экспоненциально с числом 0 вас требуется на старте.

Но как вы сказали, потому что хэш-коды распределены равномерно, то в этом нет ничего уникального, требующего хэш начать с X числа 0 в. Требуя хэш, чтобы начать с X числа 1, будут такими же, как и любой конкретной последовательности 1 и 0 быть. 0-это просто хороший выбор и понять на практике, потому что как вы сказали, вы после вычисления хэш-менее определенного количества.

Просто отметить терминологии разница кстати, это не какой-то конкретной хэш, они нацелены на определенный поднабор возможных хешей. Чтобы найти конкретный хэш будет означать ша-256 сломан, потому что вы в основном отмены операции хэширования.
