Preventing Unsolicited Commercial Communications using Blockchain 


Team Members: Satya Lokam, Nishanth Chandran, Sudheesh Singanamalla, Siddharth Prakash


Unsolicited Commercial Communications (UCC) are communications, made via voice calls or SMS, to subscribers without their consent or willingness. Apart from being a source of inconvenience, such communications also impinge on the privacy of individuals.

As we see in the figure the ecosystem comprises several entities and the earlier mechanisms of detecting, preventing, and auditing had several gaps.

Blockchains offers a revolutionary solution to fundamentally improve the regulation and delivery of commercial communications. Blockchain allows all players in the ecosystem to share customer information and transaction histories securely over a distributed data infrastructure, with the consent of the user and without compromising on the customer’s privacy or sensitive business information. The ecosystem’s participants can be certain of the digitized records being authentic and are informed in a timely manner of the progress of the scrubbing and delivery of the commercial communication. Content providers and principal entities can therefore be sure about regulatory compliances and safety of their data along the delivery chain. 

As a part of the project worked on creating several POC's to demonstrate how DLT in principle, could address the problem and scale for ~500M mobile subscribers in India.
