More than a billion mobile phone users can expect a significant respite from pesky calls and messages, as Vodafone Idea and Reliance Jio Infocomm start to roll out blockchain-based technology through partnerships with Tanla Solutions and Tech Mahindra, respectively, to tackle spammers. Bharti Airtel, with more than 325 million users, has already made a similar deployment in a tie-up with IBM.

Analysts said the ongoing deployment could be the world's largest use case for a blockchain solution in the telecom space, with nearly a billion subscribers who would get impacted by the TRAI regulation.

The deployment is being done in line with the Telecom Regulatory Authority of India’s regulations, which will come into effect by the month end, to protect mobile phone subscribers from unsolicited commercial communication, or spam calls and messages. Vodafone Idea has some 395 million users, while Jio has about 307 million, as per TRAI data.
