I led a world's-first blockchain Proof of Concept and implementation for satellite imagery. ConsenSys and The Radiant.Earth Foundation set out to create a proof of concept (PoC) to explore the art of the possible with blockchain. The minimum viable product that was built demonstrates how a production version of the PoC could leverage blockchain technology and decentralization to achieve Radiant.Earth’s goals of expanding earth observatory imagery distribution, maximizing the sharing of that imagery amongst NGOs, and maximizing donor dollars.
The PoC successfully achieved the following three objectives: restrict access to commercial satellite data, perform digital asset accounting, and improve data transparency. To achieve these objectives and ultimately prove this concept as a viable blockchain use case, ConsenSys built a system that consists of a backend Kaleido blockchain infrastructure, a robust set of metadata fields for API integrations, a series of smart contracts to enable token economics and wallets, and an intuitive graphical user interface.
In order to correctly restrict access to commercial imagery, a third-party whitelist API to validate NGO status and the accuracy of image license status was crucial. In the PoC system architecture, the metadata are provided as a roll-up through the Radiant.Earth API.
Blockchain value-add/use case
Storing metadata hashes, representing imagery license type (commercial vs. non commercial) and user type (NGO vs. non NGO) enables the blockchain ledger to serve as the single source of truth for the various stakeholders who use the system. The blockchain ledger reflects the token balances of organizations which provides an additional layer of asset access control.
