India’s BSNL Implements Blockchain to Reduce Spam Calls

India’s state-owned telecommunication company BSNL is utilizing blockchain to overcome the commercial calling menace. The company has developed a distributed ledger technology (DLT) portal to create a registry of commercial and business entities, who wish to communicate with its customers.

The initiative comes after the Telecom Regulatory Authority of India (TRAI) issued guidelines following 2018 legislation (TCCCPR). It aims to curb the problem of Unsolicited Commercial Communication (UCC) or spam calls and messages.

After registering on the DLT portal, telemarketers may only use designated number series and SMS services for commercial communications. For incoming calls, users can now set preferences based on product category, time, and mode of communication to receive promotions or block them altogether.
