I have been watching Ethereum for a couple years, have had that Mist thing installed, I lost $40 in The DAO. The time has come around again for me to pay attention and I want to do a testnet.

I have OSX on my desktop, a Linux system sitting in the corner. I can load random stuff from Git and I do a little programming in Python.

I want to get some sort of testnet going on the Linux box, and a client/wallet on OSX, then maybe on Android if it's not too much of a nuisance.

I want to be able to run this testnet stuff as a service, worst case shell in and run it under tmux. I really want a command line client, preferably Python. This installed without complaint:


And this is where I get confused. I see there are three testnets, I see tutorials on configuring them for other clients, but I don't find a current pyethereum HowTo anywhere.


Is pyethereum the right way to go about this? Or do I really have to suck it up and get familiar with the Go client? I tried that thing a while ago and I forget exactly how it made me mad, but it did.

If you use the geth client then you should use ropsten testnet, if you use parity then you should use kovan testnet (but you can switch to ropsten with a flag).

I'd recommend to start with a framework like populus, which makes easier to deploy and test contracts.

  • Why would you recommend the Ropsten network? As for my knowledge, the Ropsten is still under attack and often completely unresponsive. Has something changed? Jun 19, 2017 at 9:15
  • I didn't recommend any testnet. With geth you can access ropsten, with parity kovan. There is rinkevy, but I have not used it, so I can't say anything about it. We work with ropsten and ropsten.etherscan.io is up to date, and it seems to work okish.
