In simple words, a node is a point of intersection in communication networks. It may also receive, send, or create data on a communication channel. However, its functionality and meaning become different in a blockchain network. In a decentralized environment, a node is simply a computer connected to a cryptocurrency network.&nbsp;
It may perform different functions depending on the protocol. There’s a whole realm of <a href="https://www.thecoinrepublic.com/2020/02/25/belgium-becomes-the-latest-addition-to-the-eu-countries-setting-up-blockchain-nodes/" rel="noopener noreferrer nofollow">blockchain nodes</a> that crypto enthusiasts can explore. So, let’s dig deeper into it and see what unfolds.
<h2 class="wp-block-heading" id="strong-understanding-blockchain-nodes-strong">Understanding Blockchain Nodes</h2>
Besides the devices, nodes also represent network stakeholders who maintain the blockchain. They keep track of the distributed ledger and function as communication hubs too. Nonetheless, their primary job is to validate the legality of every block that forms the whole chain.&nbsp;
Every blockchain uses unique identifiers to differentiate between nodes. Three types of nodes are there, which include Full, Light, and Miner nodes. They perform several functions. Let’s explore them one by one for simplified learning.
<h3 class="wp-block-heading" id="strong-types-of-blockchain-nodes-strong">Types of Blockchain Nodes</h3>
The following types of nodes play different functions to maintain the optimum functionality of the blockchain.
<h4 class="wp-block-heading">Full Nodes</h4>
As the name suggests, they contain and handle the full blockchain ledger. These nodes download and store a copy of every transaction on the network. Full nodes autonomously verify all the transactions while maintaining their integrity.&nbsp;
They operate on a peer-to-peer network and don’t allow any third party to enter. Typically, blockchain developers and crypto enthusiasts manage this type of node. In the process of validation, they also remove all discrepancies like invalid signatures or double-spending.&nbsp;
<h4 class="wp-block-heading">Light Nodes</h4>
Also known as Simplified Payment Verification (SPV) nodes, they’re lighter alternatives to full nodes. They are specifically developed to work on devices with limited storage and processing power. Instead of the entire blockchain, they download a small portion of it.
For verification and validation of transactions, they rely on full nodes. Usually, they communicate with several full nodes to gather data. Since these nodes deal with a lesser amount of information, light nodes are faster. At the same time, they’re less safe as they depend on full nodes for everything.
<h4 class="wp-block-heading">Miner Nodes</h4>
Miner Nodes add new blocks to the network and verify transactions. These nodes solve complex mathematical problems and calculations to perform the job. While creating new blocks, these nodes receive high rewards too.&nbsp;
Irrespective of the type, setting up a node could be a difficult process. Things can get even trickier if one has no prior experience. However, users can now opt for Blockchain-as-a-Service (BaaS) and make it easy for them. An example of one such service is NOWNodes. It gives access to <a href="https://www.thecoinrepublic.com/2023/08/06/the-role-of-cryptocurrency-nodes-in-maintaining-a-decentralized-network/" rel="noopener noreferrer nofollow">crypto nodes</a> with a simple API key.&nbsp;
These nodes engage with mining activity and thus require specific hardware and software to perform calculations. Usually, large mining pools take part in it as they have the resources to undertake such activity. Miner nodes are essential to the PoW blockchain. They process the transactions and add new blocks that ultimately create new coins.
All the nodes play a pivotal role in maintaining the efficacy of the network. They also ensure that the blockchain can be accessed on different devices like smartphones and tablets. After knowing the types of nodes, users must know their functions too.
<h3 class="wp-block-heading" id="strong-functions-of-nodes-strong">Functions of Nodes</h3>
All functions of nodes ensure the optimum functionality of the blockchain on different fronts.
Data Processing– Nodes help in processing the data in several ways in a blockchain.
Communication– They also maintain seamless communication among different devices.
Storage Management– Nodes play a pivotal role in storing and managing the data efficiently.
Control &amp; Decision– Nodes take all the important decisions and maintain system operations.&nbsp;
Routing– They also determine the course of data in the transmission process.
Security– Nodes ensure the security of data by implementing peer-to-peer architecture.
Monitoring– Nodes monitor the overall functioning and status of the blockchain.
User Interface– They also provide an interface to make the interaction with the network easier.
<h3 class="wp-block-heading" id="strong-benefits-of-running-a-node-strong">Benefits of Running a Node</h3>
A blockchain network gets various benefits by running nodes and some of them are:
Enhanced Security– With a full-fledged system of validation and verification, it boosts the security of blockchain immeasurably.
Decentralization– With a peer-to-peer system, nodes establish a fully decentralized system that can’t be compromised so easily.&nbsp;
Optimum Control– By ousting any third-party entities, nodes deliver total control of blocks and coins to the users.&nbsp;
Transparency– With immutable records and easy access to the network, nodes make the network highly transparent.
Incentives– Nodes receive incentives in various forms like transaction fees, governance rights, and new token rewards.&nbsp;
<h3 class="wp-block-heading" id="strong-conclusion-strong">Conclusion&nbsp;</h3>
Nodes are indispensable for any PoW blockchain network. They also make the whole network more reward-centric and secure. Understanding them is the first step towards becoming a part of this sophisticated system. Thankfully, this process has become more adaptable with the help of certain services.
Today, crypto enthusiasts can join a network as a node without gaining technical expertise. Still, keeping knowledge about it will always favor the network members.
