Configuration Files Created

Besu Configuration Templates

  1. smom-dbis-138/config/config-rpc-4.toml - Ali's RPC node (2503)
  2. smom-dbis-138/config/config-rpc-luis-8a.toml - Luis's RPC node (2505)
  3. smom-dbis-138/config/config-rpc-luis-1.toml - Luis's RPC node (2506)
  4. smom-dbis-138/config/config-rpc-putu-8a.toml - Putu's RPC node (2507)
  5. smom-dbis-138/config/config-rpc-putu-1.toml - Putu's RPC node (2508)

Key Features:

  • Discovery disabled (prevents connection to Ethereum mainnet while reporting chainID 0x1 to MetaMask for wallet compatibility)
  • Standardized paths: /var/lib/besu/static-nodes.json and /var/lib/besu/permissions/permissioned-nodes.json
  • Permissioned access configuration
  • JWT authentication ready

Scripts Created/Updated

1. Main Configuration Script

File: scripts/configure-besu-chain138-nodes.sh

Purpose: Comprehensive script that:

  • Collects enodes from all Besu nodes (validators, sentries, RPC)
  • Generates static-nodes.json and permissioned-nodes.json
  • Deploys configurations to all Besu containers (including 2503-2508)
  • Configures discovery settings (disabled for RPC nodes 2503-2508)
  • Restarts Besu services

Updated VMIDs: Now includes 2503-2508 in processing loops

2. Verification Script

File: scripts/verify-chain138-config.sh

Purpose: Verifies configuration deployment:

  • Checks file existence
  • Validates discovery settings
  • Verifies peer connections

Updated VMIDs: Now includes 2503-2508 in verification

3. Quick Setup Script

File: scripts/setup-new-chain138-containers.sh

Purpose: Quick setup for new containers:

  • Runs main configuration script
  • Verifies new containers
  • Checks discovery settings

Updated VMIDs: Now includes 2503-2508 in setup


Documentation Created/Updated

1. Main Configuration Guide

File: docs/CHAIN138_BESU_CONFIGURATION.md

Status: Updated with new container allocation

2. Configuration Summary

File: docs/CHAIN138_CONFIGURATION_SUMMARY.md

Status: Updated with new container allocation

3. Access Control Model

File: docs/CHAIN138_ACCESS_CONTROL_CORRECTED.md

Status: Updated with separate containers for each identity

4. JWT Authentication Requirements

File: docs/CHAIN138_JWT_AUTH_REQUIREMENTS.md

Status: Created - Documents JWT auth requirements for all containers

5. Missing Containers List

File: docs/MISSING_CONTAINERS_LIST.md

Status: Updated with all 13 missing containers

6. Complete Implementation Summary

File: docs/CHAIN138_COMPLETE_IMPLEMENTATION.md

Status: This document


Key Features

1. Complete Isolation

  • Each operator has separate containers
  • Each identity has its own dedicated container
  • No shared infrastructure between operators
  • Complete access separation

2. JWT Authentication

  • All RPC containers require JWT authentication
  • Nginx reverse proxy configuration
  • Token-based access control
  • Identity-level permissioning

3. Discovery Control

  • Discovery disabled for all new RPC nodes (2503-2508)
  • Prevents connection to Ethereum mainnet while reporting chainID 0x1 to MetaMask (wallet compatibility feature)
  • Ensures nodes only connect via static/permissioned lists

4. Standardized Configuration

  • Consistent file paths across all nodes
  • Standardized configuration templates
  • Automated deployment scripts

Deployment Checklist

For Each New RPC Container (2503-2508)

  • Create LXC container
  • Deploy Besu configuration template
  • Configure static-nodes.json
  • Configure permissioned-nodes.json
  • Disable discovery (critical!)
  • Configure permissioned identity
  • Set up JWT authentication
  • Configure nginx reverse proxy
  • Set up firewall rules
  • Test RPC access
  • Verify peer connections

For Sentry Node (1504)

  • Create LXC container
  • Deploy Besu configuration template
  • Configure static-nodes.json
  • Configure permissioned-nodes.json
  • Enable discovery
  • Set up JWT authentication
  • Verify peer connections

For Firefly Node (6201)

  • Create LXC container
  • Deploy Firefly configuration
  • Configure ChainID 138 connection
  • Set up JWT authentication
  • Test Firefly API

Quick Start

1. Run Main Configuration

cd /home/intlc/projects/proxmox
./scripts/configure-besu-chain138-nodes.sh

This will:

  1. Collect enodes from all nodes
  2. Generate configuration files
  3. Deploy to all containers (including new ones)
  4. Configure discovery settings
  5. Restart services

2. Verify Configuration

./scripts/verify-chain138-config.sh

3. Set Up New Containers

./scripts/setup-new-chain138-containers.sh

Network Configuration

IP Address Allocation

  • 1504 (besu-sentry-5): 192.168.11.154
  • 2503 (besu-rpc-4): 192.168.11.253
  • 2504 (besu-rpc-4): 192.168.11.254
  • 2505 (besu-rpc-luis): 192.168.11.255
  • 2506 (besu-rpc-luis): 192.168.11.256
  • 2507 (besu-rpc-putu): 192.168.11.257
  • 2508 (besu-rpc-putu): 192.168.11.258
  • 6201 (firefly-2): 192.168.11.67

Port Configuration

  • P2P: 30303 (all Besu nodes)
  • RPC HTTP: 8545 (all RPC nodes)
  • RPC WebSocket: 8546 (all RPC nodes)
  • Metrics: 9545 (all Besu nodes)

Security Considerations

  1. JWT Authentication: All RPC containers require JWT tokens
  2. Access Isolation: Complete separation between operators
  3. Network Isolation: Firewall rules restrict access
  4. Identity Separation: Each identity has dedicated container
  5. Discovery Control: Disabled for RPC nodes to prevent network issues
