Building an open protocol for real-world evidence on Solana. Looking for technical feedback.

Post original

I've been working on an open-source protocol called GeoProof and would love some feedback from the Solana community. The problem I'm trying to solve is fairly simple: Any application that needs to verify a real-world event—whether it's a delivery, a retail visit, a human interaction for digital advertising, or a field inspection—usually ends up building its own proprietary verification logic. GeoProof explores whether that layer can become reusable infrastructure instead. The idea is to collect multiple evidence signals (device integrity, location, motion, timestamps, network characteristics, etc.), evaluate them against configurable policies, and produce a portable attestation with a confidence score that applications can consume. I'm not trying to replace oracles or claim "trustless" real-world verification. The goal is to standardize how evidence is evaluated before an attestation is created. I'm currently building the MVP and planning a Solana SDK. I'd really appreciate feedback from builders: Does this feel like useful infrastructure, or should it live inside individual applications? Are there existing Solana projects tackling this problem that I should study? If you were integrating something like this, what would the SDK absolutely need to provide?
