Solution Lies with Blockchain Technology

Blockchain Technology, which is also known as Distributed Ledger Technology (DLT), has the potential to meet several security and scalability challenges of the Internet of Things (IoT).

When combines with IoT technology, Blockchain helps make a machine to machine transactions possible and secure. All the information transactions are recorded and verified by multiple resources under the realm of Blockchain. And, further entered inside a common ledger distributed across every single node.

Furthermore, the information collected via IoT devices and effectively stored in Blockchain can be shared by a community of users. Selected members can maintain their copy of the information and validate any new transactions collectively through a consensus process.

What is Blockchain?

The term, “Blockchain”, which is commonly synonymous with Bitcoin has an extendible potential.

Blockchain is a large set of database that records a huge chunk of business information and provides easy access to respective enterprises. It is a database system that cannot be hacked or compromised, resulting in the safe storage of crucial information.

There are different databases, better known as blocks inside Blockchain that stores a wide range of information. Different blocks containing different information can be chained together to make a combination. Each transaction that is recorded in the block is bind together and kept safe under the Distributed Ledger Technology (DLT)

How Does Blockchain Help to Solve IoT Security Issues?

Here, you will get to understand how Blockchain helps IoT deals with several security issues.

In general, the Internet of Things network processes large scale information transactions across multiple set of devices and administrated by different organizations. This makes it difficult for the technology to pinpoint any kind of data leakage or even attack of cybercriminals.

It is here comes the role of Blockchain technology that can alleviate the security issues of IoT in the following few ways.
