A couple of years ago I got interested in Ethereum. My favourite programming language at the time was Elixir (by the way, Elixir is still my favourite language). My first contribution to the Ethereum community was Ethereumex - Elixir JSON-RPC client for the Ethereum.

In this post, I’ll describe its evolution. I won’t go into too much detail about the technical details of Ethereumex as I want this post to be about the open source, not about technology that it implements.
