Opinions in the finance industry are mainly steered by central organizations and therefore have the power to influence entire markets. For this reason, Finnoq developed an Open Source Protocol for collective opinion formation in the finance industry, drawing upon the wisdom of the Crowd. The so-called “Finnoq Core” represents the basis layer and is used for community-based reconciliation. Consequently, applications for collective ratings, regarding different fiancé products, can be developed, for instance. On top of the basis layer (Finnoq Core) there is a so-called “Service Layer”, it enables developers to integrate additionally needed modules (e.g. rating algorithms), which can be used by applications within a modularly-constructed system. Finnoq thus provides a protocol for forgery-proof opinions and sound advice from a global community. Due to the possibility of collective opinion formation, it is not necessary to rely on the perspective of single organizations or individuals.
