Whether this suits your team

Not decoded yet

We have this problem statement but have not run it through our decode pass. The government’s own description is below, unchanged.

What they'll ask you

Generated from the brief's own wording and the competition's published rules — never from a guess about what this ministry prefers.

We have not run our decode pass over this one yet, so these are the questions asked of every team rather than questions about this problem statement. The organisers’ own description is on this page, unchanged.

Has any part of this been shown at a previous event, hackathon or college project?
The guidelines are explicit: your solution must not have appeared in any previous event or programme, of any sort. A recycled project is what a team under time pressure reaches for.
Where does your data come from — a published source, one you collect, or one you generate?
No dataset is attached to this problem statement, so sourcing it is part of the work and nobody told you that.
Why not use what already exists? Name the closest thing to this that is already running.
A team that has not named the alternative themselves is answering this for the first time in the room.

1 more— the ones a panel gets to if there is time

Which single thing will you demonstrate end to end, start to finish, with nothing skipped?

The data

What the organisers attached, and what the brief assumes you can get.

Dataset from the organisers: None attached
Does the brief need data?: Nothing in the text says it depends on a dataset we would have to find.

Same organisation, same year. Reading two of theirs tells you more about what they care about than reading one.

# Context: India's Smart India Hackathon 2026

I am on a student team entering SIH 2026. Problem statement SIH26232, set by Ministry of Food Processing Industries (MoFPI).
Its official title, word for word: "Low-Cost loT Block chain Nodes for Farm-to-Fork Traceability"
Theme: Agriculture, FoodTech & Rural Development. Category: hardware.

## The organisers' full description, verbatim

<p><strong>Background:</strong></p>

<p>

Global export markets demand strict compliance with international traceability standards to combat food fraud and track contamination outbreaks. While large enterprises can afford complex cold-chain logging systems, Small and Medium Enterprises (SMEs) are priced out. Additionally, standard data loggers often lose connectivity in remote agricultural areas, creating blind spots in the supply chain data.

</p>

<p><strong>Description:</strong></p>

<p>

There is a critical need for an affordable, rugged, tamper-proof hardware device that tracks ambient environmental data during transit. The hardware must survive harsh agricultural and industrial environments, including extreme moisture, dust, and vibrations, while continuously logging metrics like temperature, humidity, and ethylene gas.

</p>

<p><strong>Expected Solution:</strong></p>

<p>

A low-power, plug-and-play IoT sensor node equipped with local cryptographic storage to ensure data integrity during cellular dropouts. The device must feature energy-harvesting capabilities, such as solar or thermal, to extend battery life indefinitely.

</p>

<p>

Upon reconnecting to a network, it must automatically sync its encrypted data directly to a decentralized ledger via lightweight protocols such as MQTT, preventing any unauthorized manipulation of the cold-chain logs.

Background:

Global export markets demand strict compliance with international traceability standards to combat food fraud and track contamination outbreaks. While large enterprises can afford complex cold-chain logging systems, Small and Medium Enterprises (SMEs) are priced out.

The hardware must survive harsh agricultural and industrial environments, including extreme moisture, dust, and vibrations, while continuously logging metrics like temperature, humidity, and ethylene gas.

Expected Solution:

A low-power, plug-and-play IoT sensor node equipped with local cryptographic storage to ensure data integrity during cellular dropouts. The device must feature energy-harvesting capabilities, such as solar or thermal, to extend battery life indefinitely.

Upon reconnecting to a network, it must automatically sync its encrypted data directly to a decentralized ledger via lightweight protocols such as MQTT, preventing any unauthorized manipulation of the cold-chain logs.
## Constraints that are not negotiable

- The judged build is a prototype demonstrated in roughly 36 hours by students, not a product.
- A jury evaluates it against this problem statement's own wording, not against general merit.
- We submit on sih.gov.in; the problem statement number and title above must match exactly.
- Your solution must not have appeared in any previous event or programme, of any sort.
- This is a hardware problem statement, so a demo needs physical components we source ourselves.

## What I want from you

1. Who actually has this problem in India, and what they do about it today.
2. What already exists — government systems, open-source projects, published research — that we should not rebuild.
3. For each item under 'what the brief never says', what the realistic answer is likely to be and how I could verify it.
4. The two or three things about this domain that a student team would get wrong without local knowledge.
## How to answer

- Everything above between quotation marks is the organisers' own wording. Treat it as the requirement.
- Do NOT invent requirements the brief does not state. If something matters and is not stated, say so and ask me, rather than assuming.
- Where you are inferring rather than reading, mark it as your inference.
- Do not guess what this ministry wants from its name. Its wording above is the only evidence.
