Hashchain-demo

This repos contains some scripts used to demo the hashchain Python package.

Raspberry Pi

This demo was meant to run on a Raspberry Pi 3 B+

Logic:

  1. Deploy a smart contract on the Ethereum Blockchain if not already existing
  2. Get temperature sensor data
  3. Hash the record using hashchain Python package
  4. Store the record in a MongoDB Database
  5. Register the hash on the Ethereum Blockchain

jsonDB

This demo is a simple example written to illustrate an article on Medium This article can be found here: link
