Hi all, I helped build this and will be happy to answer any questions here.<p>TL;DR: Using Svelte and our Ethereum API gateway, I built an interactive tutorial to learn and code on blockchain in real time.<p>Long time HN lurker and an equally long YC reject :) finally breaking the shackles and shipping something on HN. A bit of a personal back story first.<p>After recovering from a critical health condition due to tampered blood tests and reporting, I started hacking on Ethereum to see if I could leverage the tech to solve this for others. When building a couple of prototypes and eventually my first side project (CryptoVigil) on Ethereum, I realized how painful it was to code on blockchain even for an experienced developer like me. Why wasn't there a Stripe or Twilio for blockchain that I could use to quickly prototype my app with just a few lines of code. With that vision, my co-founder @anomit and I have been working on this since 2 years.<p>Whether you are a student, a novice in the world of web development or a seasoned fullstack developer, our vision is to make blockchain development accessible to all. The tutorial framework itself will be open sourced once we collect feedback from the community and iron out a few kinks. Anyone can then contribute their lesson plans and spin off their own version if they wish so.<p>Would love to hear first impressions from fellow developers here. Feel free to break stuff on the interface too!<p>(It is a developer tool intended for desktop usage. Experience on a mobile browser will be sub-par.)<p>If you want to dig deeper, check out the docs of the core API. We dog-fooded it to build this very experience!<p><a href="https://ethvigil.com/docs" rel="nofollow">https://ethvigil.com/docs</a>
