TL;DR

• StaTwig is tracking over 100 million vaccine doses with blockchain, backed by UNICEF and recognized as a UN Digital Public Good.
• StaTwig, now integrates COTI’s garbled circuits to add real-time privacy protections for sensitive cold chain data.
• This partnership proves blockchain isn’t just for finance, it’s saving lives by reducing vaccine spoilage and improving global distribution.
• COTI’s encrypted computation unlocks trusted data processing without compromising user or infrastructure privacy, a leap forward for humanitarian tech.

Every year, millions of vaccine doses are lost during transport due to poor tracking and visibility. The cold chain, the network of refrigerated storage and transport systems that keep vaccines viable is notoriously difficult to monitor. A few degrees off in temperature, a delay in delivery, or simple misreporting can mean entire batches are wasted.

Enter StaTwig, a blockchain-based supply chain company whose flagship product, VaccineLedger, is already tracking over 100 million doses across countries like Bangladesh, Costa Rica, and India. StaTwig is helping UNICEF track vaccine deliveries to children. It’s backed by Gavi, a vaccine alliance working alongside the WHO. It’s even recognized as a UN Digital Public Good, a rare badge of real-world credibility. StaTwig was also featured in Forbes Blockchain 50, 2022, a list highlighting the most valuable real-world deployments of blockchain technology. StaTwig has also partnered with major organizations like LACChain and Indian IT giant Tech Mahindra, Through this partnership, Tech Mahindra and StaTwig will work towards building a global consortium of vaccine researchers, government, pharmaceutical companies, distributors & healthcare workers.

And now, StaTwig is adding something new to its infrastructure: Privacy .

Why Supply Chain Data Needs Confidentiality

Not all transparency is good transparency especially when it comes to health systems. StaTwig’s VaccineLedger collects high-frequency data from thousands of distributed cold storage points, temperature, humidity, signal loss, unauthorized access, and more. This data tells the story of how vaccines move from warehouse to arm and flags issues before they become disasters.

But here’s the thing that data is sensitive. If it falls into the wrong hands, it could expose vulnerabilities in public health systems, invite supply sabotage, or misrepresent a country’s ability to manage critical infrastructure.

So what’s the solution? Process that data privately but without compromising speed or trust.

Where COTI Comes In: Garbled Circuits for Confidential Supply Chains

This is where COTI’s Garbled Circuits technology takes the stage. As part of the partnership, COTI’s privacy layer is being integrated into StaTwig’s Cold Chain module, allowing it to process all of the above sensor data without ever decrypting it into plaintext.

Let’s break that down simply:

• Sends alerts if no data or signal is received for a set time

• Notifies when temperature stays outside the safe range for too long

• Flags unauthorized access or risks to system security

• Keeps a secure record of all alerts on the blockchain

And all of this happens on-chain, meaning it’s provable, secure, and tamper-proof but invisible to external viewers.

As StaTwig founder Sid Chakravarthy put it:

A Live Use Case with Global Impact

According to The News Minute, an estimated 50% of vaccines go to waste globally often due to poor storage, tracking failures, and logistical bottlenecks. StaTwig aims to solve that with scalable tech that secures the supply chain from end to end.

StaTwig’s platform is deployed right now, tracking vaccines for over 65 million beneficiaries every year. Each dose gets a unique digital ID, and the system manages last-mile distribution data for health, nutrition, and agriculture programs.

They’re already working with governments like the Telangana state in India, where officials reported:

And health authorities in Bangladesh said:

With COTI’s privacy integration, the platform gets stronger and more trusted.

Why This Matters Beyond Healthcare

StaTwig + COTI is proving what blockchain can really do when it steps out of the trading pit and into the real world. We’ve seen dozens of enterprise pilots over the years, but few with actual deployment at this scale. Even fewer with verifiable results and support from organizations like UNICEF and Gavi.

Now, imagine what happens when:

• Privacy protections are standard across humanitarian systems.

• Supply chain data is useful but not exposed.

• Smart contracts can act without leaking sensitive triggers or logic.

The future has arrived and COTI’s tech is helping power it.

Final Thought: Quiet Innovation Can Still Be Massive

It’s easy to get distracted by the loudest narratives in crypto like memecoins, ETFs, bull runs. But sometimes, the most meaningful innovation is happening in the background.

COTI and StaTwig are solving real problems that protect people. This partnership shows that privacy and public health don’t have to be at odds. With the right infrastructure, they can work hand in hand.
