About ChronoLog
ChronoLog is a multi-year research effort to build a distributed shared log storage ecosystem grounded in a novel idea: using physical time as the ordering mechanism. Created and led by the Gnosis Research Center (GRC) at Illinois Institute of Technology, supported by a $4M National Science Foundation CSSI grant.
