Start Mining

This document describes a quick guide for mining on the WorldLand network.

WARNING

GPU mining is not supported yet. WorldLand currently uses CPU-based ECCPoW mining.

Generating Account

Skip this section if you have a pre-created account in an external wallet.

Generate a new account in the WorldLand console:

> personal.newAccount("YOUR_PASSWORD")

Returns data that looks like:

INFO  Your new key was generated    address=0xb8C941069cC2B71B1a00dB15E6E00A200d387039
WARN  Please backup your key file!  path=/home/user/keystore/UTC--...
WARN  Please remember your password!
"0xb8c941069cc2b71b1a00db15e6e00a200d387039"

DANGER

Be careful not to forget your password! There is no way to recover it.

You can check the list of currently added wallet addresses via the eth.accounts command:

> eth.accounts
["0xb8c941069cc2b71b1a00db15e6e00a200d387039"]

Mining

Check Balance Before Mining

Before mining, check your current balance to calculate the amount of $WL mined:

> eth.getBalance("YOUR_ADDRESS")

Or use:

> eth.getBalance(eth.accounts[0])

Mining Commands

Command	Description
miner.setEtherbase(address)	Sets the miner's address. Mining rewards will be sent to this account.
miner.start(threads)	Start mining with the specified number of threads.
miner.stop()	Stop mining.

Set Miner Address

> miner.setEtherbase(eth.accounts[0])

Start Mining

> miner.start(1)

TIP

If your CPU has enough cores, you can use a higher number of threads for faster mining.

Stop Mining

> miner.stop()

Check Mined Balance

After mining, check the amount of mined $WL:

> eth.getBalance(eth.accounts[0])

INFO

The result is in wei (the smallest unit of $WL), where 10^18 wei = 1 $WL. To display the balance in $WL:

> web3.fromWei(eth.getBalance(eth.accounts[0]), "ether")

Check Mined Block in Explorer

You can check the contents of mined blocks in the Block Explorer. Search by block number or by your wallet address.
