However nimble-footed spammers have at all times been a step or two forward of it, and undesirable messages and calls proceed to flood the telephones. In 2018, Trai launched a novel blockchain-based structure known as distributed ledger expertise (DLT), to make sure consent-based calling and messaging in addition to to create enterprise alternatives for enterprises and telcos.

It took three years for DLT to be totally carried out. Three years later, in 2024, it’s nonetheless dealing with criticism for being ineffective not solely as a result of evolving techniques of senders but additionally as a result of elementary issues that weren’t addressed whereas constructing the expertise.
ETtechWhy did this large expertise resolution fail? How does Trai plan to regulate injury?
On the coronary heart of the spam is the primal want of companies to faucet each shopper contact level to market themselves—from textual content messages and messaging apps like WhatsApp and Telegram to voice calls, emails, browser pings and in-app notifications. Enterprises need cost-effective methods to spam customers to get conversions and to upsell and cross-sell services. Nonetheless, it’s the easy SMS textual content that continues to be essentially the most used methodology throughout the globe for enterprise messaging.

This comes with perils. SMS is the most important channel of phishing in India. Over 150 million phishing messages are despatched out each month, with 60-75 million distinctive customers susceptible from assaults, as ET reported final month, quoting Sunil Bajpai, chief belief officer at Tanla Platforms. About 100,000-300,000 folks probably get scammed each month, however solely 35,000- 45,000 report it. BLOCKS IN THE CHAIN
Trai’s 2018 regulation was certainly uncommon —it was a first-of-its-kind use case of blockchain to be deployed on the planet’s largest telecom market carrying over 1.5 billion SMS messages per day. Nonetheless, it solid the burden of discovering options on telecom operators.
That they had no prototype to be taught from and this required time and funding. They needed to discover methods to implement blockchain with out dropping enterprise. For, enterprise messaging was the principle income for telcos since private messaging had shifted to platforms like WhatsApp.
Whereas telcos have been wading into uncharted territory, a number of telemarketers, aggregators and even enterprises like Paytm moved court docket, difficult a number of premises of Trai’s regulation. It was solely in 2020 that expertise instruments have been able to onboard enterprises and began parsing stay SMS site visitors by a decentralised ledger of registered enterprises (for instance, HDFC Financial institution), SMS headers (VKHDFCBK) and message templates (Hello, Your account stability is…).
ETtechThe Covid pandemic induced some hiccups and the system was lastly up and operating in early 2021. Practically 2.7 lakh enterprises have been onboarded to the brand new platform. On the outset, the brand new regime introduced a number of controls.
The outcome: subscriber complaints towards registered senders—telemarketers who’re registered with Trai to ship bulk industrial communications—fell drastically between 2021 and 2023 as clear site visitors volumes grew to new highs. “We’ve got discovered that complaints have fallen from 200,000 per thirty days to solely 30,000 now,” says a senior TRAI official, requesting anonymity.
“The DLT device additionally grew to become an important useful resource for detecting unlawful gray routes, and even for the Ministry of Residence Affairs to unearth Jamtara-type scammers,” he provides, referring to the city in Jharkhad that grew to become notorious as a hotspot of digital frauds. To dodge this, spammers began utilizing 10-digit cellular numbers. They have been now not registered with Trai. Complaints towards these unregistered senders touched 8-9 lakh per thirty days, says the official. There was one more reason for spam messages to go up. “Value wars amongst telcos led to a flooding of the system with unchecked registrations of headers and templates,” says one other telco govt.
Reliance Jio allowed free registration of headers and content material templates, and shut to five million templates have been able to be weaponised by unsolicited senders. About 20,000 templates have been registered by one financial institution. Some weren’t even used for over six months. It was the informal perspective of even reputable companies that led to the piling up of rubbish on DLT. At the moment, Rajdip Gupta, CEO of cloud communications firm Route Cellular, known as DLT a “massive failure”.
“I feel the regulator wants to know why DLT has failed. It must take a powerful stand on DLT to ensure operators are doing the suitable follow, and verifying these central (registered) IDs appropriately,” Gupta had informed ET earlier.
Trai made an effort to scrub up the mess in February 2023 when it ordered operators to take away inactive, irrelevant and rip-off headers and templates. It additionally mandated AI-based detection of rip-off and fraudulent messages. Vodafone Concept and Bharti Airtel demonstrated separate options which may detect rip-off with 99% accuracy. However, once more, it didn’t result in desired outcomes.
“These disparate AI options are working in silos, largely as a result of telcos are working in partnership with totally different expertise companions and even instantly with banks.Competitors and pricing are the important thing points right here,” says a DLT product engineer at a telecom firm, requesting anonymity DLT has a consent and preferences module, which is essentially the most essential factor for the undertaking to succeed.
This implies subscribers will be capable of specify after they wish to obtain a advertising and marketing message from a selected firm—say, between 9 am and 5 pm, on weekdays. Sadly, this by no means took off or reached subscribers.
“I imagine consent wouldn’t be helpful. It might require an overhaul of your complete DLT listing as a result of enterprises have comfortably chosen to register all the things as a service message,” says the telco govt quoted above. Service messages embody one-time passwords and banking alerts which don’t require consent. As of at this time, practically 90% templates are registered within the service class.
WHAT LIES AHEAD?
Regardless of difficulties, Trai has been attempting to erect guardrails to forestall spamming. Telecom firms have invested enormous assets over time to adjust to its instructions and properly as keep enterprise equilibrium. Nonetheless, within the race between the defender and the attacker, the latter adapts sooner and strikes a couple of steps forward.
“The regulator has issued six instructions because the anti-spam rules got here into power in 2018. Recently, the AI-based evaluation by telcos and different measures reminiscent of capping SMS volumes and discontinuing assets of spam senders have proven drastic outcomes to observe the SMS channel,” says the TRAI official quoted above.
The regulator can also be conscious that some telecom service suppliers (TSPs) will not be proactively following the codes of follow.
“Trai will name upon TSPs to determine the gaps and standardise these procedures,” says the official. If Trai succeeds, your telephone will let you already know—the variety of junk messages will fall and the pesky calls will announce themselves and fade into irrelevance.
