Project Plan - Blockchain Integration for Climate Emissions Data with Fabric and Cactus

Abstract

Use Cactus to implement integration between Fabric application such as the emissions data channel and Ethereum emissions token network:

Replace the current ethers connection to Ethereum with Cactus to perform "atomic swap" between Ethereum and Fabric. Cactus connector will call Ethereum to tokenize emissions records from Fabric, wait for the Ethereum blocks to record, then come back to Fabric to update the emissions records with the Ethereum token information.
Instead of putting private key in a config file, use Cactus to integrate with AWS Secret Manager or the open source Vault
