This is post 5 of 7 and is a recap from the DMRV Roundtable organized by ReFi DAO as part of ReFi Spring Series of Events

Holly Grimm is the project manager and developer for Astral Protocol with 25+ years in software engineering. She continues to make significant advancements in machine learning and climate mitigation.

Holly and the Astral team have been building open-source tools using spatial and location data. Their main focuses have been on verifiable spatial data (smart contract based registries of vector and spatial data assets), verifiable location claims (attestation that someone was at a particuliar place at a particular time), and Web3 Native Geospatial Data Storage Systems (stores remotely sensed data).

How does this apply to MRV?

     The registries enable MRV data collection and normalize the information for reporting across mrv providers and providing data transparency through geospatial queries and time series analysis.  Location claims verify your postiion when the data was collected and the geospatial storage data supports large files that can't be stored on chain.  

    for verification, they use hashing and anchoring to the the blockchain. An example below is from an MRV provider which gets hashed and placed on the blockchain similiar to regens data module. This allows immutable and auditable understanding of whether the data has been edited or changed.

    Holly wrapped up with a few interesting projects they've built with several groups. They are building an on-chain spatial data registry and they are doing some decectralized data storage of weather station data on orbitDB with Kolektivo Curacao Community Economy. They built a POC spatial data registry to query by area for dClimate. They are building a spatial data registry for a collective of MRV providers. Lastly, they are supporting zkMaps and their zero knowledge location proofs.

    DMRV or digital monitoring reporting and verification is an important part of the global response to climate change, enabling countries to meet international requirements around carbon credits, biodiversity, certification, and progress towards goals. This event is made up of various organizations in the space.
