Some nodes act only as wallets, some are light clients, and few are full clients running the full blockchain.
Mining is the process by which new blocks are elected via a consensus mechanism and added to the blockchain.
A Complete Guide to Understanding This Blockchain Concept
As a result, currency (Ether) is rewarded to the nodes which perform mining operations.
Miners are paid in Ether as an incentive for them to validate and verify blocks made up of transactions.
The mining process helps secure the network by verifying computations.
At a theoretical level, a miner node performs the following functions: 1.
Listens for the transactions broadcasted on the Ethereum network and determines the transactions to be processed 2.
Determines stale blocks called uncles or ommers and includes them in the block 3.
Why This Matters for Blockchain Technology
Updates the account balance with the reward earned from successfully mining the block 4.
Finally, a valid state is computed, and the block is finalized, which defines the result of all state transitions The current method of mining is based on PoW, which is similar to that of bitcoin.
When a block is deemed valid, it has to satisfy not only the general consistency requirements, but it must also contain the PoW for a given difficulty.
The PoW algorithm is due to be replaced with the PoS algorithm with the release of Serenity.

Going Deeper: Advanced Concepts
There is no set date for the release of Serenity, as this will be the final version of Ethereum.
Considerable research work has been carried out to build the PoS algorithm which is suitable for the Ethereum network.
Nodes have been named bonded validators in Casper, whereas the act of placing the security deposit is named bonding.
Miners play a vital role in reaching a consensus about the canonical state of the blockchain.
Conclusion
Nodes and miners represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
