This information can be obtained from the Geth JavaScript console by running the following command, and this command should be run on the peer to which Raspberry Pi is going to connect: > admin.nodeInfo This will show the output similar to the one shown in the following screenshot: geth nodeInfo After this step, further instructions presented in can be followed to connect Raspberry Pi to the other node on the private network.
In the example, the Raspberry Pi will be connected to the network ID 786 created in , Ethereum Development Environment.
A Complete Guide to Understanding This Blockchain Concept
The key is to use the same genesis file created previously and different port numbers.
Same genesis file will ensure that clients connect to the same network in which the genesis file originated from.
Different ports are not a strict requirement, however, if the two nodes are running under a private network and access from an environment external to the network is required then a combination of DMZ, router and port forwarding will be used.
Therefore, it is recommended to use different TCP ports to allow port forwarding to work correctly.
The –identity switch shown in the following command for first node set up, which hasn’t been introduced previously, allows for an identifying name to be specified for the node.
Why This Matters for Blockchain Technology
Understanding Static nodes configuration is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
