The problem Acropolis solves

Acropolis enables Authorized Anonymous Voting through Signatures over Public Keys. The cryptographic identity of each User is treated as a Secret Input and never revealed to the public. Only the Signature issued by the Authorities for a “KYC-ed” user, alongside with the corresponding Public Key (one Public Key per election that is owned by the authority) are published for each election. An election is defined as a cycle with a fixed set of options to choose from and government issued identities.
