I'm a novice. I'm looking for instructions on how to configure geth so it sends my mined eth to coinbase.

In my head, I think the process is:

  1. Sync the blockchain geth --datadir /data/ethData --autodag --verbosity 1
  2. wait for it to finish. Get an ETH address from https://www.coinbase.com/addresses geth --etherbase '0xa4d8e9cae4d04b093aac82e6cd355b6b963fb7ff' --mine
  3. Profit!

Is that correct?

here's what I do on my private Ethereum Testnets (you don't need to create your own network though):

  1. Starting the geth node and entering the JS Console

    geth --networkid XXXX console
    
  2. Creating an account. You'll be asked to provide a passphrase.

    personal.newAccount()
    
  3. Defining your initial/primary account as coinbase:

    miner.setEtherbase(eth.accounts[0])
    
  4. Verify coinbase:

    eth.coinbase
    

After that's done you can either exit the JS Console or start the mining process by:

miner.start()

In case DAG wasn't created, it should automatically be created.

I hope this helps and answers your question!

Cheers

  • Looks like you always create a new account on each worker. Is that correct? If so, that means you move the eth generated from each account/worker to coinbase at a later time. Is that also a correct assumption? – Albert T. Wong Feb 15 '17 at 17:00

Is that correct?

Yes, that's correct. But...

...I think you're conflating two ideas here.

coinbase.com is a trading/exchange site, which relatively recently added ETH to the currencies it sells.

A coinbase account - which Ethereum also calls the etherbase - is by default the primary local account. This can, however, be set to any address you wish - it doesn't have to be an account you created on your local machine.

  • Right, totally forgot to take a coinbase.com account into my answer. Thanks for pointing this out here! – Borinho Feb 15 '17 at 12:52
  • Should you always have a local account for each worker? – Albert T. Wong Feb 15 '17 at 16:59
  • If there isn't a local etherbase account already set up, or if you haven't specified an account (local or otherwise) in the command you use to start the miner, it won't start. Have a look at the instructions at github.com/ethereum/go-ethereum/wiki/Mining – Richard Horrocks Feb 15 '17 at 17:08
  • In case it's not clear: Yes, you can create a local etherbase (coinbase) account before you start mining, or you can specify an account/address which you haven't created on your machine, like you specified in your question. – Richard Horrocks Feb 15 '17 at 17:10

If you want a constant coinbase among all nodes, you can simply set the etherbase manually as follows:

miner.setEtherbase('0xa4d8e9cae4d04b093aac82e6cd355b6b963fb7ff');

AFAIK, you don't even need to have a keystore file, i.e. the specified account does not need to be in eth.accounts, but I'm not sure about this.

Yes, that's correct. Etherbase is the "target" account for where to put the reward from mining.

It's a miner setting:

MINER OPTIONS:
  --mine                    Enable mining
  --minerthreads value      Number of CPU threads to use for mining (default: 8)
  --etherbase value         Public address for block mining rewards (default = first account created) (default: "0")
  --targetgaslimit value    Target gas limit sets the artificial target gas floor for the blocks to mine (default: 4712388)
  --gasprice "18000000000"  Minimal gas price to accept for mining a transactions
  --extradata value         Block extra data set by the miner (default = client version)

You can specify it when running Geth like this:

geth --mine --etherbase 0xa4d8e9cae4d04b093aac82e6cd355b6b963fb7ff --gasprice "1000000000"

gasprice is the minimum price for executing transactions. It's a function of the load on the network.
