How Can Blockchain Influence IoT?

Blockchain is basically a digital, distributed ledger technology that enables peer-to-peer transactions. When combined with IoT, blockchain could enable machine-to-machine transactions. The effectiveness of Blockchain IoT projects depends considerably on an understanding of the value generated from the combination. 

Security is one of the formidable concerns in IoT, which has delayed large-scale deployment. In addition, IoT devices also have vulnerabilities to DDoS attacks. At the same time, existing IoT networks also experience issues of scalability. Since IoT devices are slowly becoming integral parts of the daily lives of people, it is important for enterprises to address security and scalability concerns.

Blockchain Brings a Lot of Value in IoT

The effect of blockchain on addressing security and scalability concerns in IoT showcases the ideal foundation for establishing blockchain IoT startups. IoT networks could process data transactions throughout multiple devices under the ownership and administration of different organizations. As a result, it could be difficult to identify the source of any data leakage in the event of cybercriminal attacks. Blockchain could offer an ideal solution to these issues in the following ways.

  • The distributed ledger in blockchain is immutable or tamper-proof, thereby removing the need for trust among involved parties. 
  • Blockchain offers another layer of security by ensuring the limited possibilities for overwriting existing data records.
  • Blockchain brings transparency by enabling individuals with authorization to access the network and transaction history.
  • Faster transaction processing and coordination among the different types of connected devices with blockchain can offer scalability. 
  • Blockchain could also help IoT companies by reducing costs through the elimination of processing overheads for IoT gateways. 

According to IBM, the basic foundation for establishing blockchain IoT projects refers to the benefits of using blockchain for IoT. The characteristic contributions of blockchain for IoT include the following,
