Designing a blockchain-based IoT infrastructure with Ethereum, Swarm and LoRa
This addresses the problem of scalable and secure IoT data management for smart city applications, but it is incremental as it combines existing technologies.
The paper tackles the challenges of deploying, managing, and securing data from IoT devices by proposing a standardized infrastructure using blockchain technology, resulting in a system that ensures high availability and minimal security risks by integrating LoRa, Swarm, and Ethereum.
Today, the number of IoT devices in all aspects of life is exponentially increasing. The cities we are living in are getting smarter and informing us about our surroundings in a contextual manner. However, there lay significant challenges of deploying, managing and collecting data from these devices, in addition to the problem of storing and mining that data for higher-quality IoT services. Blockchain technology, even in today's nascent form, contains the pillars to create a common, distributed, trustless and autonomous infrastructure system. This paper describes a standardized IoT infrastructure; where data is stored on a DDOS-resistant, fault-tolerant, distributed storage service and data access is managed by a decentralized, trustless blockchain. The illustrated system used LoRa as the emerging network technology, Swarm as the distributed data storage and Ethereum as the blockchain platform. Such a data backend will ensure high availability with minimal security risks while replacing traditional backend systems with a single "smart contract".
