Yes, we've noticed the alarming info regarding this project such as:

— Some of the partnerships, memberships and media have no confirmation or reference from the stated institutions.
— The websites for ArcBlock and for Krypital media (where two ArcBlock advisors are from) were registered on the same date.
— There is no access to the code at the moment and ArcBlock is not an open source project (Open Chain Access Protocol is promised by founder after the RC1 milestone).
— Some info on social media about team members and community admins is diverting from what is stated on the website.
— A lot of concerns about the project being a scam on social media.
— There is no official statement yet regarding the rumors from the founder except the answer on Reddit.
