# What is a Full Core Node? Full Core nodes are the most advanced type of Datagram Core node and form a critical part of the Datagram Fabric Network. They handle key functions like routing, validating, and optimizing data, which keeps the network fast, secure, and reliable. By operating a Full Core node, you help build the decentralized infrastructure that allows Datagram to scale and support a wide range of services. These nodes also verify that Partner Core nodes connected to the Datagram Core Substrate are properly authorized to access the network and earn rewards, helping ensure transparency and trust across the ecosystem. Full Core nodes are the backbone of Datagram’s performance. They create strong, fault-tolerant data pathways and offer rewards to operators who contribute resources. For anyone committed to supporting and shaping the future of decentralized connectivity, running a Full Core node is the most impactful way to get involved. {% hint style="warning" %} [Learn more about Datagram's Node Network](/datagram-architecture/node-network.md) {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
