Ion (IoT device with local ledger) Application architecture of room rent IoT application (IoT device without local ledger) There are obvious security concerns which arise from exposing RPC interfaces publicly; therefore, it is recommended that this option is used only on private networks and if required to be used on public networks appropriate security measures are put in place, such as allowing only the known IP addresses to connect to the geth RPC interface.
This can be achieved by a combination of disabling peer discovery mechanisms and HTTP- RPC server listening interfaces.
A Complete Guide to Understanding This Blockchain Concept
The traditional network security measures such as firewalls, Transport Layer Security (TLS) and certificates can also be used but have not been discussed in this example.
Now Truffle can be used to deploy the contract on the private network ID 786 to which at this point the Raspberry Pi is connected.
Truffle deploy can be performed simply by using the following shown command; it is assumed that truffle init and other preliminaries discussed in , Ethereum Development Environment has already been performed: $ truffle migrate It should produce the output similar to the following screenshot:
Why This Matters for Blockchain Technology
Understanding Application architecture of room rent IoT applicat 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.
