How to Set Up a Private Ethereum Blockchain in 20 Minutes
Every year, ArcTouch brings together its employees for a three-day hackathon, where groups set out to prototype an idea using new and emerging technologies. This year, we had many blockchain hackathon projects — and we think this speaks to both the growing interest in blockchain by our staff and the potential for companies to benefit from it. My group chose to implement an identity verification system built on the blockchain. The idea was to store someone’s proof of age, which a bartender or sales clerk could reference in lieu of a physical ID such as a driver’s license. Since we planned to leverage smart contracts, we opted for an Ethereum blockchain.

Instead, we looked at a several options for quickly spinning up a private blockchain. By far, the easiest approach is to use a cloud service such as Azure to host a private blockchain...
