Already deployed and available on Arbitrum, Celo, Base, and Ethereum Sepolia — a Typescript SDK is in development.\n\nVerifiable Geocomputation: Systems that implement geospatial algorithms in smart contracts or cryptographic protocols, ensuring computations were done correctly.\n\nP2P Geospatial Data Infrastructure: Peer-to-peer protocols for storing, managing, and efficiently accessing geospatial data (sensor readings, drone scans, satellite imagery) on decentralized storage systems like IPFS and Arweave.\n\nWhy It Matters\nOur tools, standards and research unlocks new kinds of trustworthy, verifiable location-aware decentralized apps, including:\n\nEnvironmental monitoring and climate action (digital MRV, sustainability-linked finance)\n\nTransparent mobility and transportation systems (congestion zones, smart parking)\n\nGovernance and compliance tools (local DAOs, digital jurisdictions, fraud detection)\n\nInteractive experiences (location-based gaming, metaverse applications, geotagged social posts)\n\nHumanitarian and human rights applications (secure reporting, accountability)\n\nProgress & Milestones\nRecently completed:\n\nPublished our first peer-reviewed paper with the University of Maryland Geographical Sciences Department\n\nBuilt and deployed the Astral API, a unified gateway to the decentralized geospatial web\n\nDeployed Location Proof Protocol on Arbitrum, Celo, Base, Ethereum Sepolia\n\nReleased Astral Logbook, consumer-facing location proof app\n\nIntegrated the Location Proof Protocol with TOUCHGRASS.CLUB, an accountability app to help people get outside\n\nIntegrated Location Proof Protocol with IPFS\n\nSponsored Funding the Commons x Earth Commons Hackathon — over ten builder submissions\n\nLaunched comprehensive developer resources (docs.astral.global)\n\nMerged with EASIER Data Initiative to form the Decentralized Geospatial Collaborative to aligned decentralized GIS research and co-maintain open source repos\n\nCo-chairing the Decentralized Geospatial Web Working Group\n\nNext:\n\nPublish the Astral SDK as an npm package, giving Typescript developers an easy way to create, publish, fetch and verify location proofs\n\nDesign and build a block scanner-style UI — including map visualizations — to explore location proofs\n\nSupport pilot ecosystem developers (could this be you? Reach out!)\n\nPresent our first peer-reviewed paper at GISRUK 2025 in Bristol, UK\n\nResearch the landscape of proof-of-location systems, share our findings\n\nDevelop the first Location Proof Recipe Extensions\n\nRefine the beta Location Proof Protocol into a technical specification to share with the geospatial community via the Open Geospatial Consortium\n\nSubmit for more extensive grant funding to support our open source ecosystem development\n\nR+D on a smart contract library for geometric and topological algorithms (Spatial.sol)\n\nResearch privacy-preserving location proofs, including zero knowledge- and TEE-based methods\n\nDeepening collaboration with UMD’s EASIER Data Initiative\n\nExpanding open community of builders, researchers, ecosystem contributors\n\nSelected Accomplishments\nEthereum Attestation Service Fellowship & Demo-Day Shortlist (2024)\n\nFilecoin Development Grant (decentralized satellite imagery) (2020)\n\nKERNEL Genesis Block Presenter (2020)\n\nEuropean Space Agency’s Living Planet Symposium Speaker (2022)\n\nArweave Prize Winner (Future of Blockchain 2020)\n\nPresenter, Open Geospatial Consortium (2022)\n\nCo-founded Decentralized Geospatial Web Working Group (2023)\n\nHow You Can Help\nWe invite builders, researchers, and open-source contributors passionate about decentralized spatial computing to collaborate. Your Gitcoin contributions directly fund ongoing R&D, open-source software, and community-building—accelerating decentralized geospatial innovation.", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "AstralProtocol", "projectTwitter": "AstralProtocol"}
