This project involves a software ‘platform of platforms,’ distinguished here as the Open Climate Platform, the development of climate communication protocols, and a shared user interface as portal to the system. The Platform acts as a common integrator that can reconcile climate records and functions from both legacy and DLT-based climate platforms in the pursuit of helping maintain a decentralized ‘ledger of ledgers’. With climate actors and their associated records mapped in a shared network— ranging from countries, to companies to individuals— DLT and other cryptographic tools are primarily used to:
