                Кратко об алгоритмах консенсуса
              
          
    pBFT = Practical Byzantine Fault Tolerant

Требуется n = 3f + 1 узлов, чтобы противостоять сговору и злонамеренным
действиям f участников.
1999 Barbara Liskov et al.
Для достижения консенсуса участники обмениваются сообщениями в три этапа.

на двух этапах каждый участник отправляет сообщения всем остальным.
Каждое из них нужно отдельно подписать.

для консенсуса между 7 участниками нужно отправить 71 сообщение


для консенсуса между 10 участниками нужно отправить 142 сообщения
