ENS_data_analysis
ELK stack project for data analysis on name registration and events on the Ethereum Name Service. Requires a more robust distributed event aggregation service -
eth-lightShow-uottahack
Art project from hackathon. 3D printed IoT device featuring arduino, LED lights, live multi-user interaction, nodeJs backend and ethereum integration for firing and storing events which affect the device. Requires a more IoT centric plasma sidechain or private chain. Article -
ethwaterloo-bit
Basic identity on the blockchain PoC. Allows easy login to dapps using current standard social networks like FB and creation of a federated onchain identity and migration of social networks and data while allowing account recovery in private key loss scenarios. Hopefully will act as a substrate layer for future onchain social networks. -

pet-shop-tut
Truffle petshop tutorial. TODO: Create similiar one using MIT licensed ethersjs -
static_example
Example of a static ethereum backed site for beginners workshops
This is a demonstration of how ethereum can be used to run serverless dapps in the simplest form with the least amount of code, tooling or setup.
In this example we'll be publishing a pre-written greeter contract which responds with the greeting phrase it is bootstrapped with. Then we'll attempt to call the greeting contracts greet function from our front-end js and render it.
Quick learning assignment: Implement front-end js+html to change the greeting phrase in the greeter contract.
- Chrome browser + meta-mask plugin
- Nodejs
Run:
cd static_example
npm install && npm start
Switch to the rinkeby testnet using metamask and go to the browser address and you should see "Data: Hello world from rinkeby!"
npm install -g truffle ethereumjs-testrpc
Run testrpc server: testrpc
Truffle commands:
truffle compile
truffle migrate
