The Carbon Accounting Token (CAT) contract directory.

A smart contract library and dApp for tracking emission inventories across hydrocarbon fuel supply chains.

This project is curretnly undegoing restructuring:

1. CAT network for private transfers and tracking of emission inventories by large companies (private network, e.g., Besu or Fabric)
2. CAT dapp SDK for interactng with the CAT network (currently using node.js).
3. Carbon organizational governance (COG) identity netowor for registering and managing the identities/roles of carbon management organizations / service providers. Use a public/permissionsed identity network, e.g., Indy.
4. COG contracts for auditing private emission inventories (private network), registering carbon managment assets and exposing these to public carbon token programs (public network). E.g., emission certificates and carbon offset credits.

Getting Started

Prerequisites

• Solidity - Smart contract compiler

npm install -g solc

• Truffle - Development toolkit

npm install -g truffle

Blockcahin network setup

Setup local development network

Compile any changes to contract library truffle compile

Use Ganache

npm install -g ganache-cli

./run.sh 

If Ganache app already running truffle migrate --network development

See truffle-config.js for network config

Using local Besu network e.g. Besu quorum-test-network.

This is to deploy on private/permissioned EVM using POA consensus.

npx quorum-dev-quickstart

cd quorum-test-network

Start nodes as docker containers

./run.sh

See README.md for futher instructions and node management.

To deploy local network

truffle migrate --network local

For public network using an ethereum testnet (Ropsten)

Set INFURA_ROPSTEN and correspoinding PRIVATE_KEY envrionment variables in .env from avaiable wallet

truffle migrate --network ropsten

See truffle-config.js to configure a different network

Or flatten contract

truffle-flattener contracts/CAT.sol >> flatContract.sol

and compile/deploy CAT contract using Remix Use the following MultisigWalletFactory (mswfactory) address as input (used to generate escrow contracts). 0x0A4aC8cf056b464a4c1737293bc1E52eC469F09A Latest CAT contract address is 0xFC6E33bBE510BDAe4737809Aec5C60B653D0E8bE

Run dapp

Set CAT_ADDR (CAT contract address) in dapp/.env Set NETWORK_URL .env variable to desired network (e.g., ropsten, ganache, besu)

npm install

npm start

if running a local network navigate to localhost
