Master Thesis

Project Name: hypenergy

This repositpry containts the code for my Master's thesis: the implementation of a decentralised application called hypenergy, a peer-to-peer marketplace for community-based local electricity markets.

• The full thesis can be downloaded here.
• The chaincode describing the transaction logic can be found in: packages/energymarket-cc/src.
• Test scripts and unit tests can be found in: packages/energymarket-cc/tests

Prerequisites

• Node 8.15.0 (support for node 10.x.x was announced and could also work now)
• Docker 18.09.2 (make sure installation contains docker-compose)
• npm 6.4.1
• nvm can be used to install and switch between different node versions

Start

• Install dependencies (from the root of the project)
  npm i
• Create a new development blockchain network and install the chaincode on all peers (from the root of your project)
  npm start
• Create a market by invoking the createMarket transaction (if timeout, try again)
  hurl invoke energymarket energymarket_createMarket "{\"id\":\"MKT\",\"auctionTime\":900000,\"gridBuyPrice\":25,\"gridSellPrice\":5}" -o org1 -u user1
• Run tests
  npm run test

Play Around

• Check out the ledger: http://localhost:5084
• A debugger can be connected at http://localhost:8888
