ewasm “WRC20” token contract coding challenge

This document describes a simple contract in pseudocode and gives a couple of test cases for it.

The challenge is designed to be fairly easy to implement in a language of choice, compiled to wasm and interacted with. It is loosely based on the ERC20 token standard, named "WRC20", where the W stands for WebAssembly.

External interface

The contract has two features:

# Apple hides old versions of stuff at https://developer.apple.com/download/more/
# Install the latest XCode (8.0).
#   We used to install the XCode Command Line Tools 7.3 here, but that would just upset the most recent versions of brew.
#   So we're going to install all our brew dependencies first, and then downgrade the tools. You can switch back after

Updates

This document was published on 21.09.2015 for a freelance employer. Some changes since then (14.02.2016):

1. Koa.js no longer uses co-routines, it has switched to Babel's async/await. yield and await are used almost in the same way, so I see no point to rewrite the examples.
