How to Add External Quorum Nodes to Enterprise Ethereum Quorum Networks

Introduction to External Quorum Node Integration

Enterprise Ethereum Quorum networks can incorporate nodes hosted outside their primary blockchain service provider. This guide explains how to integrate external Quorum nodes into an existing network while maintaining security and functionality.

Step-by-Step: Adding External Nodes to Your Quorum Network

Follow this structured process to connect third-party Quorum nodes to your enterprise network:

1. Network Preparation

Navigate to My Ethereum in your blockchain dashboard
Select the target Quorum network and click Add Node
Create a new Ethereum network if none exists (creation guide)

2. Node Configuration

Complete the node creation form with:
- Descriptive node name
- External Node checkbox selected
Access the new node's Configuration Page from My Nodes

3. Technical Requirements for External Nodes

Prepare these critical connection parameters from your external node:

Parameter	Description
IP	Public IP for Quorum node and tx-manager
TMPort	Transaction manager service port
P2pPort	P2P communication port
TMPub	Transaction manager public key
NodePub	Quorum node public key
WSPort	(Optional) Websocket service port
RpcPort	(Optional) RPC service port

4. Node Registration

Click Edit on the Configuration Page
Enter all collected node parameters
Submit for network validation

5. Consensus Participation (Optional)

For nodes to participate in block creation:

Contact existing consensus node administrators
Manually add node via RPC interface calls

Important Maintenance Considerations

Configuration Synchronization Alert:
When network changes occur:

Configuration Pages auto-update
External nodes require manual configuration synchronization
Use the update command: ./bootstrap.sh update

Temporary Test Node Setup (Non-Production)

For development environments only:

Installation Requirements

Docker environment setup:

sudo apt update && sudo apt install docker.io
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod 755 /usr/local/bin/docker-compose

Quorum node initialization:

wget https://baas-sdk.oss-cn-hangzhou.aliyuncs.com/bootstrap-1.0.0.sh -O bootstrap.sh && chmod 755 bootstrap.sh && ./bootstrap.sh

Node Management Commands

Command	Function
`./bootstrap.sh info`	View node status
`./bootstrap.sh update`	Refresh node configuration
`./bootstrap.sh up`	Start node services
`./bootstrap.sh down`	Stop node services

Frequently Asked Questions

Q: Can external nodes participate in consensus immediately?
A: No, existing consensus nodes must manually approve new participants via RPC calls.

Q: How often should external node configurations be updated?
A: After any network topology changes, or at least quarterly for security updates.

Q: Are test environment nodes suitable for production?
A: Absolutely not. Production nodes require proper security hardening and monitoring.

Q: What's the typical latency for external node integration?
A: Configuration typically takes 15-30 minutes after all parameters are verified.
