International Data Corp. (IDC) predicts that, in 2025, 75% of the

55.7 billion devices will link to an IoT platform of some sort.

As per Forbes, “The Internet of Things (IoT) has become

ubiquitous, and the number of connected devices is expected to

grow to 29.3 billion by 2023.”

Obviously, for any IoT ecosystem, some of the biggest issues can be

privacy, security, and scalability. For billions of devices, we need a

super-fast ecosystem which would be availed by the 5G network. At

the same time, the underlying DLT network can handle the issues of

transparency, immutability, and trust with cryptography.

Also, it would be a great challenge for the centralized servers to

manage such huge load for authentication and access management.

Decentralized identity backed by Blockchain or DLT can be pretty

useful to assign identity to every machine, whether big or small, and

at the same time, authenticating them to any third party. This

mechanism would ensure that a device can be identified by millions

of other devices and servers leading to an efficient and secure

machine-to-machine or M2M communication.

Hyperledger Fabric has recently come up with a paper where they

have demonstrated how decentralized identity for the IoT machines

can improve security, network quality assurance, customer

experience, visibility, transparency, data access, and user content in

the IoT devices.

various BSS/OSS systems in the Telecom domain, such as order

management, CRM, billing, user and enterprise dashboards, as
