Introduction
The rapid expansion of the Internet of Things (IoT) has generated a massive network of connected devices, but interoperability and security remain critical challenges. Blockchain technology offers a decentralized and tamper-proof solution for data exchange, authentication, and automation. This article explores the integration of blockchain with IoT devices, challenges, solutions, and future innovations.
Understanding Blockchain and IoT Interoperability
What is Blockchain?
Blockchain is a distributed ledger technology that records transactions securely and transparently. It ensures data integrity, prevents tampering, and eliminates the need for intermediaries.
What is IoT?
IoT consists of interconnected smart devices that collect, process, and exchange data over the internet. Examples include smart home devices, industrial sensors, and healthcare wearables.
Why is Interoperability Important?
Interoperability ensures seamless communication between different IoT platforms, enabling efficient automation, data security, and cost reduction.
Challenges in Blockchain-IoT Integration
Scalability and Performance
