    header = 4 байта Little-endian ver + prev_block в хексе в обратном порядке + mkrl_root в хексе в обратном порядке + (все  Little-endian) 4 байта time_, bits, nonce

    итого длина буфера под header = 4 + длина prev_block + длина mkrl_root + 12

    Это процедура конкатенации.

    У меня нет времени самостоятельно в ней разбираться.

    Предлагаю 200 гр. если перепишите процедуру на С.

    Возможно, что hashlib.sha256(header).digest() принимает аргумент в текстовом

    формате. 

    Моя программа SHA256 принимает 16 слов 32-битовых  типа usigned int.

    Поэтому мне нужен аналогичный код на С в котором  header должен быть в HEX формате.

    Я уже выбрал исполнителя.

    Надеюсь на сотрудничество в будущем.

    С уважением,

    Виктор
