i just saw an announcement about an updated website with  'a proper roadmap and time lines' on discord,so i assume it's a new roadmap for cognito.
the question is,why did you put your whitepaper on Q3~Q4 2019 ? why do not put it on Q1 2019 or Q4 2018 ?
and personally i am a little bit dissapointed with your roadmap because it's not in detail or i should say it's created in a rush.
