Ideologi (pronounced the same as ideology) is a universal marketplace of ideas: an online platform for mass deliberation, consensus generation, co-creation and more. It can be used by an an unlimited number of participants to rapidly interrogate any possible subject matter, while filtering out the noise commonly associated with group collaboration (i.e. trolling, social bias, polarization and information cascades). As a peer-to-peer program that runs on Ethereum's decentralized application network, it operates without the use of any central server or web site. All of its processes (messaging, file transfers, score tabulation, commission payouts, escrow, fees, notarization, rewards, settlements, etc.) work without the direct control or manipulation of central administrators or necessary trusted parties. The financial medium of exchange among its users is a bitcoin-inspired cryptocurrency called Ion. Its code is open source (GNU Affero General Public License 3.0) and available for public examination and modification. And since there isn't an organization that owns the application, the system is controlled through consensus generated by its community of users, supporters, developers, and transaction operators (known collectively as ideologists).
