Interested in Byzantine Agreement?
     
There exists a constructive, cryptographic algorithm for reaching Byzantine
Agreement in constant expected time.
     
The algorithm requires only polynomial local computation
from each processor.
     
The algorithm does not require any pre-processing.
(At the start, the processors only know everyone's identity.)
     
The algorithm works in the most adversarial cryptographic scenario. (It
tolerates up to n/3 polynomial-time faulty processors, dynamically
chosen, capable of arbitrary
Byzantine behaviour, rushing, eavesdropping, undetected
cooperation, etc.)
