While cryptocurrencies are the most known application of the technology known as blockchain, it is by no means the only one. Blockchain is being used in many other product solutions across the world, like in banking products and in shipping monitoring projects. This time is none other than Microsoft, the software giant, that will leverage the power of blockchain to fight a great problem in India: the growing hassle of spam calls.
According to a report from Truecaller, a company that runs an app that deals with call classification, an average cell phone user in India receives more than 20 spam calls in a month, a problem that is aggravated by each passing year. The people that is most responsible for this behavior are advertising companies and carriers that sell their info to other companies.
But Tech Mahindra, a Hindi company that is associated with Microsoft plans to fight this problem with the use of a blockchain based system. Rajesh Dhuddu, Global Practice Leader of Blockchain at the startup declared:
Blockchain as a technology is a powerful tool to combat the issue of spam calls and fraud risks, to protect user information, as well as the integrity of the telecom sector
The tool that they will use will let them coordinate the actions to stop spam across multiple computers of different service providers that have different pieces of information about spam numbers. Then with blockchain, they would be able to share this info without having a centralized hub that could be modified by possible attackers.
Microsoft Azure, a programming platform will serve as the backbone to this solution that many providers will use to comply with the new regulations of the TRAI (Telecom Regulatory Authority of India) that dictate that anyone can opt out of these annoying calls in any moment. Another new interesting application for blockchain technology to be put to test in the near future.
