Governance in the Inuminati DAO will only be available to a select group of individuals.

Criteria will include the amount of token you own, but will not be the only criteria in selecting seats on the board.

There will be 13 faction leaders, and each faction will consist of 7 board members.

Once accepted, members are granted access to the Inuminati Discord group.

Collabland will verify holdings.

The “Algo AI Channel” of the discord group will only be accessible to those with a predetermined amount of $Numi.
