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.
