Nodes in telecommunications and software engineering usually refer to components of larger, interconnected networks. However, in the realm of cryptocurrency, nodes are one of the components responsible for running blockchain algorithms to verify and authenticate each transaction.
This article will discuss in more depth what nodes are and how they work in blockchain. Let's take a look!
Understanding what a node is
A blockchain essentially acts as a digital distributed ledger that records all transactions involving cryptocurrency. Each blockchain consists of blocks that are connected to each other, forming a continuous chain.
Nodes, which are generally computer systems, make up each blockchain. They store a copy of the blockchain's main protocol and maintain the entire transaction history.
Thanks to decentralization, anyone around the world can run a node, as long as it is connected to a decentralized blockchain network and has the necessary resources.

Types of Blockchain Nodes
Here are the three main types of blockchain nodes:
Full nodes (Full nodes)
This node stores the entire blockchain, with every block stored within it. The individuals behind full nodes usually have a deep understanding of the blockchain, making them ideal validators for transactions.
Storing an entire blockchain requires substantial storage space, but pruning – a process of removing unnecessary data – can shrink blockchain nodes, saving storage space for future transactions and faster network speeds.
Light node (light node)
Light nodes do not store the complete history of the blockchain but store a partial set of data to ensure accurate transactions.
Many function as crypto wallets, connecting to full nodes and acting as a bridge between the wallet and the blockchain. It provides an easy way to buy, sell, and exchange cryptocurrencies on crypto exchanges via blockchain.
Masternodes
Similar to full nodes, masternodes are only used to validate and store transactions and cannot contribute to the creation of new blocks in the blockchain.
Masternode owners receive incentives for their validation efforts in the form of the blockchain's native cryptocurrency.
Why does node size matter?
Some centralized blockchains require you to go through a registration process if you want to set up a node, which some argue can lead to centralizing only approved nodes.
Depending on the blockchain, nodes have different technical requirements. It is important for decentralization that these requirements are not too burdensome, allowing everyday individuals to run a node.
Criticism of Solana's node requirements as too large raises concerns about the protocol's potential centralization.
