Talk Title: Robust P2P Systems Without Playing Games

Talk Abst

ract:
I''ll present recent work in which we take a protocol tolerant
only of crash failures and turn it into a protocol tolerant
of Byzanti

ne failures. Different from prior work our translation
does not requi

re that the protocol is round-based and the
output protocol scales to

many nodes. Also different from
prior work we not only prevent nodes

from behaving badly
but force them to fully participate in the protoco

l or die.
This prevents behavior omission failures like freeloading. <
