The following is the ABI of the contract: “constant”: false, “inputs”: [ “name”: “x”, “type”: “uint8” ], “name”: “getRent”, “outputs”: [ “name”: “”, “type”: “bool” ], “payable”: false, “stateMutability”: “nonpayable”, “type”: “function” }, “anonymous”: false, “inputs”: [ “indexed”: false, “name”: “returnValue”, “type”: “bool” ], “name”: “roomRented”, “type”: “event” There are two methods by which the Raspberry Pi node can connect to the private blockchain via the web3 interface.
The first is where the Raspberry Pi device is running its own geth client locally and maintains its ledger, but with resource-constrained devices, it is not possible to run a full geth node or even a light node in a few circumstances.

In that case, the second method, which uses web3 provider can be used to connect to the appropriate RPC channel.
This will be shown later in the client JavaScript Node.js program.
A comparison of both of these approaches is 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.
Key Points to Remember
- The first is where the Raspberry Pi device is running its own geth client locally and maintains its ledger, but with resource-constrained devices, it is not possible to run a full geth node or even a light node in a few circumstances.
- In that case, the second method, which uses web3 provider can be used to connect to the appropriate RPC channel.
- This will be shown later in the client JavaScript Node.js program.
- A comparison of both of these approaches is 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.
