Confidential, Decentralized Location-Based Data Services (Short Paper) Adams, Benjamin spatial data privacy smart contract differential privacy There are many privacy risks when location data is collected and aggregated. We introduce the notion of using confidential smart contracts for building location-based decentralized applications that are privacy preserving. We describe a spatial library for smart contracts that run on Secret Network, a blockchain network that runs smart contracts in secure enclaves running in trusted execution environments. The library supports not only basic geometric operations but also cloaking and differential privacy mechanisms applied to spatial data stored in the contract.
