3. We believe the future of decentralized applications will emulate the world of centralized ap- plications we have today. We intend to learn from the way these centralized applications scale to plan for our decentralized future. Since most centralized applications at scale use far more data than could reasonably be stored in a shared ledger, Icarus is built to support applications that utilize any quantity of data at any scale. We introduce the idea of oﬀ-chain Artifacts that live in the Icarus Artifact Network (IAN ), which runs parallel to the shared ledger. Dapp developers can incorporate bulky data like media content, ”internet of things” data, or AI/machine learning data, into the logic of their smart contracts without sacriﬁcing security or scalability. Finally, and arguably most important, we introduce the Icarus Guru which enables the trustless analytical querying of data distributed across the IAN. Data researchers can pay data owners to query their data for analytics, without requiring the data owners to reveal their data.
