Server Side Ethereum Proof of Concept using Rails

This app demonstrates who to write server side Ethereum code. Most of the tutorials I found focus on Dapps -- I'd recommend this Dapp tutorial by ConsenSys if that's what you're looking for. However, I wanted to manipulate an Ethereum node from a backend server.

System dependencies

• cpp-ethereum - for solc, the solidity contract compiler
• ethereumjs-testrpc - A Ethereum JSON-RPC simulator. Let's you run tests really fast.
• geth - For running a real JSON-RPC node.
• PostgreSQL - in case I need a database later, though I may yank that out.

Goals

• Manipulate Ethereum wallet and execute transactions on the server side, including creating contracts and accounts.
• Create unit tests and integration tests.
• Create an automated deployment mechanism (normally I'd use Heroku, but the geth node dependency means that won't work.)
• Communicate with a separate web server.

Done So Far

• Run some unit tests against contracts.
• Use the Ethereum Ruby api.

Running test suite

1. Make sure testrpc is running
2. rake spec
