Decentralized IoT applications are transforming industries by leveraging the convergence of Web3 and IoT to solve pressing challenges, enable smarter operations, and create resilient systems. In smart cities, IoT-connected infrastructure is being paired with blockchain technology to manage utilities, traffic, and public services more transparently and efficiently. For instance, energy grids now integrate blockchain-based systems to securely monitor and optimize energy distribution while enabling peer-to-peer energy trading between residents using IoT-enabled meters. This decentralization empowers citizens and reduces reliance on centralized utility monopolies.
The logistics industry is also undergoing a paradigm shift. Companies are using IoT sensors for real-time tracking of shipments across global supply chains, while decentralized ledgers ensure data immutability and transparency. This minimizes fraud, improves traceability, and fosters trust among stakeholders. In healthcare, IoT wearables monitor patient health, storing critical data on decentralized networks to ensure privacy and availability while enabling secure sharing with approved providers. Agriculture is leveraging IoT devices combined with blockchain smart contracts to automate irrigation systems, optimize yields, and ensure traceable food supply chains, responding to consumer demand for ethical sourcing.
