Several regulatory bodies in India are implementing blockchain technology to regulate spam calling in the Indian headset market, the second largest in the world, as reported by Economic Times.

The Securities and Exchange Board of India, Reserve Bank of India and Telecom Regulatory Authority of India have introduced new legislation to utilize blockchain to safeguard customers against unsolicited calls and messages. 

Tanla was one of the first companies to adhere to the regulation, creating a blockchain system called Trubloq which allows users to set and manage their communication preferences.
