# Edge Node (or Contributor Node)

Edge Nodes are specialized components within the Subnet Ecosystem:

**Roles**: A node bound to specific protocols built on the Subnet Infrastructure

**Resource Contribution:** Edge Nodes can provide various computational resources to the Subnet, enhance the overall capacity and performance of the Subnet

* RAM (Memory)
* CPU (Processing power)
* GPU (Graphics processing capabilities)
* Storage (Data retention capacity)
* Internet bandwidth

**Reward Structure:**

Edge Nodes earn reward based on their contributed **DCU** (Distributed Computational Units) both from Network layer and Protocol layer (dual tokens mining)

**Protocol Specificity:** Each Edge Node is associated with a particular protocol, allowing for specialized functions within the Subnet Ecosystem

By leveraging these Edge Nodes, the Subnet can distribute computational tasks and storage requirements across a network of contributors, potentially improving scalability, resilience, and performance of the overall system.
