A node is essentially a computer. A Kaspa node is a vital part of the Kaspa ecosystem, contributing to its decentralization, security, and efficiency. The primary software for running a Kaspa node is called Kaspad. This is the reference full node program that allows users to participate in the Kaspa network by validating transactions and blocks.

Kaspa is open-source code running on a peer-to-peer network of computers. Like Bitcoin, there is no central point of failure. With more consistent mining rewards, Kaspa encourages more decentralization than Bitcoin.

It's actually very easy to do. The easiest way would be to watch this video that is fewer than 4 minutes long: How to run a node. If you are already familiar with running nodes and would like to delve into the specifics and deep dive into more documentation about Kaspa Nodes, including how to run Kaspa nodes using Raspberry Pi or running a Kaspa Archival Node, check out the Kaspa Wiki section dedicated to nodes here: Running Nodes on Kaspa.

It increases decentralization and security of the network. It also allows you to have access to your own wallet, increasing your own privacy. By running a node, you help secure the Kaspa network. Your node validates transactions and blocks, ensuring the integrity of the blockDAG. Every node contributes to the decentralization of the network. A more decentralized network is generally more resilient and less susceptible to attacks. Kaspa's unique BlockDAG allows for quicker transaction confirmations. By running a node, you can experience and support this enhanced speed firsthand. Operating a node connects you with the Kaspa community. You can share experiences, troubleshoot issues, and stay updated on the latest developments in the network.

Running a node provides practical insights into how the blockDAG operates (including being able to see a real time BlockDAG visualizer). It’s a great way to deepen your understanding of cryptocurrency technology. Recent developments, like Rusty Kaspa, have made it easier to run a node with lower hardware requirements, making it more accessible for users.

If you run testnet-11 (10 BPS), then it allows developers to more accurately fine tune and test upgrades for improved versions of Kaspa as they prepare for the upcoming Crescendo hard fork.
