In the most fundamental words, blockchain technology is a distributed ledger system that tracks and secures transactions. Telecommunication industry transacts when we exchange phone credits in a voice call, text message, or data usage. Telecom industry has already been transformed a lot in the recent times.

We started from landline connections and witnessed a sea change when mobile phones came to use. And today, internet-based applications like Whatsapp, Facebook, Skype and Viber have severely transformed the industry. These applications have killed text message revenue stream, but have also maximized the use of data packs at the same time. Though, from a helicopter view, we see profit margins of network providers dwindling. And, in this competitive market, when most of the services are available for free, like calling or texting over Facebook or Whatsapp, the companies in Telecom sector will find their survival difficult in near future.
