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:

noamnelke

1. Converts the recipient's public key to PKCS8

ssh-keygen -f id_rsa.pub -e -m PKCS8 > id_rsa.pkcs8.pubkey

One way to obtain a recipient's public key is from GitHub, by adding .keys to their profile url, e.g. https://github.com/noamnelke.keys

2. Encrypt a string

This pipes a secret string into openssl, encrypts it with the recipient's public key and pipes the result to openssl again to transcode it into base64 (without the last step it would be binary, which is fine for a file, but harder to paste somewhere).

eWASM Roadmap 2017-2018

UPDATE: for a clearer and up to date picture please refer to https://github.com/ewasm and https://gitter.im/ewasm/lobby

(Intro: https://github.com/ewasm)

The goal is to launch a preliminary test environment ("test net") with eWASM very early 2018 and to have a stable eWASM test ecosystem by mid-2018.

Transaction Gas:

libethcore/Transactionbase.cpp

In function baseGasRequired, print the initial g, it can be 'transaction cost' or 'create cost', and print g again before it gets returned, now it will contain the cost for the sent in the transaction.
