Open-source Blockchain Ethereum Starter App

https://github.com/Nikhil22/angular-truffle-starter-dapp

An open source starter app built with Angular 4 and Truffle. The project is a boilerplate app that allows users to compile and deploy smart contracts on the Ethereum blockchain. The app is one of the most starred Angular-Truffle integrations.

Truffle Quick Start Guide

https://www.packtpub.com/product/truffle-quick-start-guide/9781789132540

This book covers the writing of smart contracts and the building of decentralized applications with Truffle.

It starts with the basics of Truffle, briefly explaining how it integrates Solidity and Web3. Then, it goes into migration, testing, and integrating Truffle with the use of popular JavaScript frameworks. Lastly, it covers shipping your decentralized application and packaging it into a product.

The goal is for the reader to be able to write smart contracts and build decentralized applications with Truffle on Ethereum blockchains.

CryptoTrend

https://www.producthunt.com/products/cryptotrend#cryptotrend

A Vue-based, real-time Google Trends and price data for over 1,000 cryptos, trending data sortable by market cap and other variables. It was built in a weekend and made it to Product Hunt's top 10 daily products.

Python Vehicle Detection
