I am very new to Ethereum. I have setup two machines, a Windows 10 machine and a Ubuntu 17 Server in the Cloud. Both of these nodes are synced to the testnet.

But when I start mining on these to machines using miner.start(2), I am not getting any ethers on the Ubuntu machine.

Below is the log from the Ubuntu machine;

Please advise on what am I missing here.

  • Which testnet are you on? (Kovan, Ropsten, or Rinkeby) Jun 29, 2017 at 11:03
  • @TjadenHess Log says ChainID: 3, so I am on Ropsten?

  • Could just be that you don't have enough hash power to get ETH. What's your hashrate? Jun 29, 2017 at 12:08
  • @TjadenHess it is 28932

  • How long have you been mining? My calculation says it should take about 7 hours on average for you to find a block Jun 29, 2017 at 12:32

The issue is simply that despite being a testnet, there is about .05GH/s of hashing power currently on Ropsten which can make it impractical for small computers to mine their own ETH.

You can get around this issue in a couple ways:

  1. Use a faucet. A few can be found on google, and will give you a few ETH for free.
  2. Use the Kovan testnet. This requires you to use the parity client, but it does not use proof of work and instead has a semi-centralized system for distributing test ETH.
