On Raspberry Pi, the following command is required to be run to start geth and to sync it with other nodes (in this case only one node).
The following is the command: $ ./geth –networkid 786 –maxpeers 5 –rpc –rpcapi web3,eth,debug,personal,net –rpccorsdomain “*” –port 30302 –identity “raspberry” This should produce the output similar to the one shown in the following screenshot.

When the output contains the row displaying Block synchronisation started it means that the node has connected successfully to its peer.
This can be further verified by running commands in the geth console on both nodes. screenshot.
The geth client can be attached by simply running the following command on the Raspberry Pi: $ geth attach This will open the JavaScript geth console for interacting with the geth node.
We can use admin.peers command to see the connected peers: geth console admin peers command running on Raspberry Pi Similarly, we can attach to the geth instance by running the following command on the first node: $ geth attach ipc:.ethereum/privatenet/geth.ipc Once the console is available admin.peers can be run to reveal the details about other connected nodes. screenshot:
Why This Matters for Blockchain Technology
Understanding Raspberry Pi node setup 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.

Conclusion
Raspberry Pi node setup represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
