Blockchain in internet of things: Challenges and Solutions

Understand

The Internet of Things IoT is experiencing exponential growth in research and industry, but it still suffers from privacy and security vulnerabilities.

• Conventional security and privacy approaches tend to be inapplicable for IoT, mainly due to its decentralized topology and the resource-constraints of the majority of its devices.
• BlockChain BC that underpin the crypto-currency Bitcoin have been recently used to provide security and privacy in peer-to-peer networks with similar topologies to IoT.
• However, BCs are computationally expensive and involve high bandwidth overhead and delays, which are not suitable for IoT devices.
