For a couple of days in March 2021, thousands and thousands of Indians instantly couldn’t entry most of the apps and providers they relied on for on a regular basis life. Every time they request a one-time passcode (OTP) to authenticate a financial institution transaction, retrieve a forgotten social media login, or register for a vaccine appointment, they ended up ready without end for an SMS textual content that was by no means on its means.
Why? As it seems, the one-time passcodes required to run these providers have been blocked by India’s new blockchain-powered SMS “scrubbing” system designed to chop down on spam texts.
Obviously, this wasn’t the supposed results of the anti-spam system. The plan itself had noble intentions, however attributable to some anticompetitive lawsuits and bunches of forms, most firms held off on complying with the brand new telecommunication guidelines — which finally prevented their OTPs from reaching their customers. To repair the difficulty, India’s telecom authority paused the rollout of the anti-spam blockchain community, thereby permitting OTP deliveries to renew and restoring entry to everybody’s banks, social media accounts, and the whole lot else.
Looking again on the way in which issues transpired, it’s onerous to see India’s anti-spam plan as something however a failure. But even though the rollout of this expertise was so badly bungled, India’s blockchain-powered spam-blocking concept nonetheless holds huge promise. In plenty of methods, it’s a glimpse into what blockchain expertise might do past cryptocurrency — and it’s price revisiting.
The unending scourge of spam
Globally talking, spam has persistently grown by double-digit figures for the previous couple of years — endlessly.
In the United States, cell subscribers acquired a report 7.4 billion spam textual content messages in March 2021, up 37% from the month earlier than. In 2020, losses from fraudulent SMS amounted to just about $86 million, in line with the Federal Trade Commission.
And in a rustic like India, which is dwelling to 1.36 billion individuals (over 4 occasions the inhabitants of the U.S.), the issue is even worse.
Giulia Porter, vp of RoboKiller, a spam-blocking service, believes the rationale worldwide spam points have been prevalent is solely due to the complexity and variety of the telecommunications trade — the place there are not any incentives or laws to cease spam calls in a unified means.
Porter provides that developments in tech have been a double-edged sword since they’ve additionally allowed spammers to always adapt and give you new strategies to evade enforcement efforts.
So, within the face of such a big and unruly downside, India determined to check out a robust new device: Blockchains.
Inside India’s anti-spam blockchain
India’s blockchain framework, which is designed to curb “unsolicited commercial communication,” permits authorities to convey accountability and traceability into the nation’s rampant spam trade. It requires entrepreneurs, bulk senders, and cell carriers to register themselves on a digital ledger. This community additionally hosts customers’ preferences over whether or not they’d prefer to obtain unsolicited texts.
So, solely when a mass business SMS meets the system’s antifraud requirements — and the individual focused has opted into receiving the message — is it allowed to be delivered. The relaxation is scrubbed.
In a rustic the place each individual receives a number of fraudulent calls and texts per day, it was excessive time India took motion on it. No one anticipated it to show to a blockchain-based expertise.
India has practically a billion cell subscribers and greater than a billion business SMS messages are transmitted within the nation day-after-day. Relying on conventional channels to arrange these heaps of delicate information — that are being managed by dozens of cell carriers and entrepreneurs — would have meant hoarding all of it in a central location, thereby making it much less safe and extra weak to breaches (as has occurred a number of occasions previously in India). A distributed, blockchain-based method appeared like a significantly better concept.
With this sort of distributed structure in thoughts, India constructed a system wherein every telecom operator has the flexibility to ascertain a devoted node within the nation’s cell community. Every operator’s purchasers, entrepreneurs, and particular person cell subscribers exist as a department of that telecom’s node. All these sources’ inputs routinely circulation via the community in actual time and eradicate the necessity for any specific entity to keep up its separate database.
When politics and expertise collide
In principle, India’s resolution to undertake a blockchain is sound. After all, blockchain’s distributed nature is simply the form of technological spine authorities must deal with an issue as scattered and messy as spam. Since every name or textual content is verified for traces of fraud and cross-checked towards an individual’s selection, there’s little room for scammers to avoid safeguards.
India’s answer, sadly, didn’t go in line with plan because the nation mismanaged the implementation. So far, it’s been hit with a myriad of roadblocks, and essentially the most vital of them has to do with the truth that native authorities concentrated the community’s management into the fingers of a single firm known as Tanla. Complaints from different entrepreneurs and telecommunications firms argued that Tanla’s personal enterprise depends on mass SMS advertising and marketing campaigns, thereby elevating a battle of curiosity. The expertise’s rollout has been dragged via the courts and has but to show its efficacy in the true world.
Raja Jurdak, a professor of distributed methods at Australia’s Queensland University of Technology, advised Digital Trends that whereas the concept is engaging on the floor, it includes “several issues, including trust, scalability, and privacy.” Since, as an alternative of conserving the blockchain community public, India has opted for a non-public one, Jurdak says it raises privateness issues over how the information of tons of of thousands and thousands of customers is dealt with.
Jurdak provides that the focus of entry and information at a single firm goes towards blockchain’s primary design attribute, which is the decentralization of belief.
Can blockchain save us from spam as soon as and for all?

Jurdak suggests rising decentralization and offering appropriate incentives to potential blockchain validators to take part in sustaining the blockchain — much like a cryptocurrency — which might subsequently scale back the necessity to belief particular person individuals.
India isn’t alone, both. Blockchain has been quietly upending a variety of legacy providers throughout the globe and upgrading them for the brand new, virtual-first world. Some hospitals within the United Kingdom, as an illustration, are using blockchain to trace the temperature of a number of coronavirus vaccines earlier than administering them to sufferers.
Similarly, a world consortium of telecom operators and distributors is constructing a distributed ledger to crack down on “wangiri” fraud calls. The “wangiri” idea includes malicious actors leaving an abrupt missed name from a world quantity to individuals. When somebody calls again, these actors are capable of rack up the hefty worldwide connection charges. With blockchain, telecom firms are capable of share intelligence on detected “wangiri” calls with one another in actual time and incorporate the worldwide information into their algorithms to proactively put an finish to future such frauds.
A central blockchain requires everybody to position the belief in a single group that will get to “play god,” Brian Behlendorf, Linux Foundation’s normal supervisor for Blockchain, Healthcare, and Identity, advised Digital Trends
“Distributed ledger technology allows all parties to place their trust in the system,” he says. “That changes everything.”
