# Port Chain Optimization: Blockchain Node 8082 → 8008

## 🎯 Update Summary

**Action**: Moved Blockchain Node from port 8082 to port 8008 to close the gap in the 8000+ port chain

**Date**: March 4, 2026

**Reason**: Create a complete, sequential port chain from 8000-8009 for better organization and consistency
