Types of Nodes in Blockchain
Full Node
A full node is a computer that stores the entire copy of a blockchain’s transaction history and maintains it independently. It verifies every transaction on the network, checks for errors or fraudulent activities, and adds them to the blockchain if they are valid. A full node is responsible for maintaining consensus in the network and ensuring that all nodes agree on the current state of the blockchain.
Mining Node
A mining node is a computer that performs complex mathematical calculations to validate transactions and create new blocks. It uses specialized software called miners to solve cryptographic puzzles, which requires immense computational power. When a miner solves a puzzle, it is rewarded with newly minted coins, as well as transaction fees. Mining nodes are responsible for securing the network by solving complex mathematical problems and adding new blocks to the blockchain.
Lightweight Node
A lightweight node is a computer that only stores a subset of a blockchain’s transaction history and does not participate in mining activities. It relies on other nodes in the network to verify transactions and maintain the consensus. A lightweight node is typically used by users who don’t need to run full-scale applications or perform complex mathematical calculations.
The Node that Doesn’t Exist in Blockchain
Despite the different types of nodes found in a blockchain network, there is no type of node that doesn’t exist. All three types of nodes are essential to the functioning of a blockchain network.
Full nodes ensure that all nodes agree on the current state of the blockchain and maintain consensus by verifying every transaction on the network. They also provide an immutable record of all transactions, which makes it possible to trace the origin of assets and prevent fraudulent activities.

Real-Life Examples of Node Types in Blockchain
Full Nodes
One example of a full node is the Bitcoin Core software, which allows users to run a full Bitcoin node on their computer. The software downloads and verifies every transaction on the network, as well as maintains its own copy of the blockchain’s transaction history.
Mining Node
s
One example of a mining node is ASIC miners, which are specialized hardware devices that are designed specifically for Bitcoin and other cryptocurrency mining. These miners use complex mathematical algorithms to solve puzzles and validate transactions on the network. Another example is GPUs (Graphics Processing Units), which are commonly used for mining Ethereum and other cryptocurrencies.
Lightweight Node

One example of a lightweight node is mobile wallets like MyEtherWallet, which allows users to access their Ethereum account on their smartphone without running a full-scale application. Another example is web wallets like Coinbase, which allow users to access their cryptocurrency accounts through their web browser.
FAQs
What is the difference between a full node and a lightweight node?
A full node stores the entire copy of a blockchain’s transaction history, while a lightweight node only stores a subset of the transaction history. Full nodes are responsible for maintaining consensus in the network and ensuring that all nodes agree on the current state of the blockchain, while lightweight nodes rely on other nodes in the network to verify transactions and maintain consensus.

How do I set up a full node in a blockchain network?
Setting up a full node in a blockchain network can vary depending on the network and software being used. However, in general, you will need to download the software for your chosen network, such as Bitcoin Core or Ethereum Geth, and follow the instructions provided by the developers. This may involve configuring the software to your specific needs, such as setting up a wallet or specifying which nodes to use for synchronization. Once the software is set up, you will need to wait for it to download and synchronize with the rest of the network, which can take several hours or even days depending on the size of the blockchain and your internet connection speed.
How do I set up a mining node in a blockchain network?
Setting up a mining node in a blockchain network typically involves installing specialized software, such as ASIC miners or GPUs, and configuring it to work with your chosen network. You will need to provide the necessary settings, such as the blockchain address and cryptocurrency being mined, and start the miner software. The miner software will then begin working on complex mathematical problems, which require immense computational power. When a miner solves a puzzle, it is rewarded with newly minted coins, as well as transaction fees. It’s important to note that mining can be very energy-intensive, so you may need to invest in specialized hardware or use a cloud-based
