Astral provides open-source tools + infrastructure empowering developers to build user-centric, verifiable location-based apps on the decentralized web.

We create the tools, standards and protocols necessary for a decentralized geospatial web, simplifying how Web3 developers integrate spatial and location data into their apps.

Weâve developed the Location Proof Protocol, introducing a new Web3 primitive representing user locations. The Location Proof Protocol isÂ a framework for creating location proofs, which are digitally-signed claims about the timing and location of events.

Weâve already launched our beta, including the specification, reference implementation, API and SDK. The Location Proof Protocol is built on EAS â our v0.1 schema is deployed on multiple chains: Celo, Base, Arbitrum and Ethereum Sepolia.

In addition to location proofs, weâre researching verifiable geocomputation systems âÂ geospatial algorithms in smart contracts and cryptographic protocols. Weâve also been doing R+D on p2p geospatial data systems for efficiently storing, managing, and accessing diverse spatial data types, such as sensor measurements, drone imagery, and satellite data.

These tools unlock a new category of trustworthy, location-aware decentralized applications and robust geospatial workflows, enabling use cases like:

Environmental monitoring and digital MRV
Climate modeling and forecasting
Transparent transport and mobility systems
Interactive location-based games
Compliance verification and fraud detection
Secure human rights reporting

Our codebase is open source â it's co-maintained with the Decentralized Geospatial Collaborative, an open source project we co-founded with a team at the University of Marylandâs Geographical Sciences Department. We also conduct academic research, looking ahead at how Web3 design principles can enhance the capabilities of geospatial computing technologies âÂ you can read our vision paper here.
