Every ecosystem needs data aggregators. By their work of collecting, processing and transmitting information, they are a founding pillar of any complex structure. Their accessibility and reliability are essential to the sustainability of the ecosystems in which they are integrated.
In the decentralized finance (DeFi) world, many data aggregators are made available to applications, but none of them meet the requirements of a decentralized environment. In fact, all of them are fully centralized, at every stage of their protocol:
- Data collection is centralized (Web2 forms)
- Data processing is centralized (opaque internal processing)
- Data transmission is centralized (Web2 APIs)
This leads to all the problems of centralization that DeFi tries to escape: vulnerability of centralized servers, uncertainty about data reliability, inaccessibility for on-chain applications... This is why the creation of a decentralized data aggregator seems necessary.
