# Mine Iron Fish

Miners are essential to the health of the Iron Fish network. Without them, blocks won't be generated and transactions won't be transmitted.

## Requirements#

Install Iron Fish by following the instructions here.

## Quick start#

Start your node by running the following command:

ironfish start

Open a new terminal window and run:

ironfish miners:start

## Changing the default account#

If you want to use a different account to store the miners fee, you can create a new account by running the following command:

ironfish wallet:create newAccount

And then set it up as default:

ironfish wallet:use newAccount

## Set block graffiti (optional)#

Iron Fish blocks contain a 32-byte publicly-visible field called graffiti that can be set by the block's miner. To set this value to a UTF-8 encoded string on the blocks you mine, update the blockGraffiti config option:

ironfish config:set blockGraffiti "<your graffiti here>"

## Join a mining pool#

You can join a mining pool in order to increase your chances of mining a block. Block rewards are typically split among miners based on their respective contributions. We also run a basic mining pool that anyone can join. To get started, retrieve the public key of the account you want to use:

And use that public key to join the mining pool:

ironfish miners:start --pool pool.ironfish.network --address <PUBLIC KEY>

Join our Discord if you're interested in creating a different pool for Iron Fish.

## Troubleshooting#

#### My miner has been running for a long time - but I haven't mined a block yet#

• Difficulty (and therefore time to mine a block) can change depending on how fast blocks are mined on the Iron Fish network.
• Make sure you are correctly connected to the Iron Fish network (you should see Connected to the Iron Fish network in your node logs).

#### Not connected to a node - waiting 5s before retrying#

Make sure that your node is currently running. If you are using a different datadir argument to start your node, make sure to use it as well when starting the miner. For example:

• Make sure your node is synced with the network before starting the miner. Run ironfish status to check if your node is still syncing.
