What is the difference between a miner and a node in Monero?

A miner does the work needed to compete to add new blocks to Monero’s transaction history. A node checks transactions and blocks against Monero’s rules and shares valid information with other nodes. You can run a node without mining, and you can mine without running your own node.

A miner competes to create blocks

A block is a batch of transactions added to the blockchain, Monero’s shared record of payments. As a miner, your computer repeatedly tries calculations until it finds a result that meets the network’s current target.

This process is called proof of work. It makes creating blocks costly in computing power and electricity, which helps protect the transaction history from being rewritten.

Monero uses RandomX, a mining method designed to favor CPUs—the general-purpose processors inside computers. Blocks arrive about every two minutes on average. The mining difficulty, which controls how hard it is to find a qualifying result, adjusts every block.

When a miner finds a valid block that the network accepts, its reward includes:

• The block’s newly created XMR, Monero’s currency.
• The transaction fees included in that block.

Monero’s ongoing base reward is 0.6 XMR per block. That is a network-level reward, not an amount you should expect your computer to earn.

A node checks rather than competes

A full node is software that independently checks Monero’s blockchain against its rules. It downloads and verifies blocks and communicates with other nodes.

Among other things, your node checks that:

• Transactions have valid cryptographic proofs—mathematical evidence that they follow the rules.
• Coins are not being spent twice.
• A block meets the required proof-of-work target.
• The miner has not claimed more reward than allowed.

This is the key distinction: miners propose blocks; nodes decide whether those blocks follow the rules. Finding a mining solution does not give a miner permission to create extra coins or include invalid transactions. Other nodes reject an invalid block.

Running a node does not earn you a mining reward by itself. It generally uses storage, internet data, and processing power, rather than continuously performing the competitive calculations that mining requires.

How miners and nodes work together

If you mine independently, called solo mining, mining software typically works with your own node. The node provides the information needed to build a candidate block. The miner searches for a qualifying result, and the node can broadcast the completed block.

If you join a mining pool, you combine your work with other miners and receive payouts under the pool’s rules. With a conventional pool, the pool usually runs the node infrastructure, so you do not need your own node just to contribute mining work.

One computer can perform both roles. They are different jobs, not necessarily different machines.

What this means for browser mining

If a website uses your browser for mining calculations, your browser is acting as a mining worker—not automatically as a full Monero node.

A browser interface alone does not prove what is being mined or how payouts work. Before participating, check what software runs, who supplies the mining work, what fees apply, and how you can withdraw. Only use devices you own or have explicit permission to use.

The bottom line

You mine to compete for block rewards. You run a node to verify Monero for yourself and help share valid network information. You can do either or both, but simply running a node does not generate XMR.
