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. Iron Fish is still at the testnet stage.

We are currently running an incentivized testnet where you can earn points by mining blocks and contributing to the network. To participate, visit our testnet website to learn more.

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 accounts:create newAccount

And then set it up as default:

ironfish accounts: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:

ironfish accounts:address

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:

ironfish miners:start --datadir=~/.ironfish2/

The trees aren't the same size as the chain

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