"geth --testnet" - Ethereum Node on Ropsten Network

This section describes how to run a 'geth' Ethereum node on the Ropsten Network.

If you are tired of waiting for your "geth" Ethereum node to be synchronized on the Ethereum main network, you can run it on the Ethereum Ropsten test network first.

There are two ways to run "geth" on the Ethereum Ropsten test network: "geth --testnet" or "geth --networkid 3".

Here is how I start my Ethereum node on the Ropsten test network:

C:\>\local\bin\geth.exe --testnet --fast console 2>> geth-test.log
Welcome to the Geth JavaScript console!

instance: Geth/v1.8.1-stable-1e67410e/windows-386/go1.9.2
coinbase: 0x536cb768f4976445c1e71f1317a0056d755568d6
at block: 0 (Wed, 31 Dec 1969 19:00:00 EST)
 datadir: C:\Users\herong\AppData\Roaming\Ethereum\testnet
 modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 
    rpc:1.0 txpool:1.0 web3:1.0
    
> eth.syncing
{
  currentBlock: 3307,
  highestBlock: 2768297,
  knownStates: 0,
  pulledStates: 0,
  startingBlock: 0
}

> ...

> eth.syncing
{
  currentBlock: 106037,
  highestBlock: 2768392,
  knownStates: 88223,
  pulledStates: 79164,
  startingBlock: 0
}

Keep it running. It will finish the synchronization in few hours.
