Xandeum Protocol
Distributed Network Monitoring & Analytics PlatformXandeum is a sophisticated enterprise-grade distributed network monitoring and analytics platform specifically designed for the Xandeum Protocol ecosystem. As CTO, I've architected this platform to provide real-time visibility, performance analytics, and intelligent insights into a global network of distributed nodes (PNodes) that form the backbone of our decentralized infrastructure. This platform serves as the central nervous system for network operators, providing comprehensive observability across thousands of geographically distributed nodes while maintaining sub-second response times and 99.9% uptime SLAs.
Core Mission

Database Schema & Data Models
PNode (Primary Node Entity)
The fundamental unit of our distributed network - each PNode represents a participating node in the Xandeum network.
model PNode {
Where:
- Stake: Token commitment (0-100 scale)
- Uptime: Availability percentage (0-100)
- Latency Score: 100 - latency (normalized 0-100)
- Risk Score: Inverse risk assessment (0-100, lower is better)
}
Xandeum Node Score (XDN Score) Algorithm
Our proprietary scoring algorithm that evaluates node quality across multiple dimensions:
XDN Score = (Stake × 0.4) + (Uptime × 0.3) + (Latency Score × 0.2) + (Risk Score × 0.1)
Where:
- Stake: Token commitment (0-100 scale)
- Uptime: Availability percentage (0-100)
- Latency Score: 100 - latency (normalized 0-100)
- Risk Score: Inverse risk assessment (0-100, lower is better)
PNodeMetric (Real-time Performance Data)
Granular performance metrics collected every 30 seconds from each node.
model PNodeMetric {
cpuUsagePercent Float
memoryUsagePercent Float
networkLatency Int
bandwidthUsed BigInt
diskReadOps Int
diskWriteOps Int
}
NetworkSnapshot (Daily Network Statistics)
Aggregated network health metrics captured daily for historical analysis.
model NetworkSnapshot {
totalNodes Int
activeNodes Int

Network Health Algorithm
Formula:
Network Health = (Active Nodes Ratio × 80) + (Latency Score × 20)
Where Latency Score = max(0, 100 - Average Latency)
