What is Machine Learning? Machine learning is a subset of AI that is concerned with algorithms that can improve through experience. Experience in this case generally translates to being fed lots of data. What’s more interesting than what machine learning is though, is what it can do. Beating humans at board games, driving cars, filtering

Today, many software projects rely on some form of iterative software development lifecycle (SDLC) to incrementally deliver features to their users. A feature is identified, analyzed, designed, scoped, implemented, tested, and ultimately shipped to users – and this cycle is repeated for all features throughout a project’s lifetime. These types of methodologies are especially useful

Your team realizes that testing is valuable. Your team creates tests for already completed features. The result was encouraging and your team even found a few bugs hiding in the application. Your team returns to feature development and attempts to add new tests. Features took more time to complete because of the need to create

Your team presses on, adding features and your user base continues to grow. After a few months, cracks begin to surface. Users started

Introduction Now that we’ve demystified smart contracts and better understand what they are and how they work, let’s build our own contract on top of the Ethereum blockchain. Because smart contracts are computer programs at their core, many of the concepts that we’ll use to build a basic contract will seem familiar. Major advancements in
