Idena is a Proof-Of-Person protocol employing a 'one-person-one-vote' consensus algorithm for its network. Prioritizing people over tokens, Idena ensures that voting power is distributed equally among all participants, thus preventing a small group from gaining excessive control

Idena offers a puppet-resistant 'cryptoidentity' primitive, utilized for democratic voting, quadratic funding, airdrops, and decentralized governance. Idena serves as one of the Gitcoin Passport stamp providers

The Idena's Proof-Of-Personhood protocol is accessible to anyone and does not require any personal information. Users actively engage in mutual verification by challenging each other with AI-resistant, user-generated FLIP tests. This process is done in a synchronous ceremony, which ensures that individuals cannot spoof multiple accounts.

The network is protected from Sybil attacks through regular validations and Sublinear Staking. Sublinear Staking economy prevents large stake holders from dominating the network and encourages small individuals to secure their identities with stakes ensuring democratic staking rewards distribution.
