We're building infrastructure for verifiable location claims on the decentralized web. Our current focus is proof-of-location — one of the three pillars of the decentralized geospatial web.
Key concepts:
- Location stamps — Verifiable artifacts from proof-of-location systems
- Location evidence — Composite bundles from multiple independent sources
- Evidence functions — Evaluation methods that produce credibility assessments
Work in progress
