Cocoblock: What an NGO Learned Putting Smallholder Cocoa on the Blockchain
Here’s the case study at a glance:
Cocoblock, a blockchain traceability pilot for organic cocoa
Nitidae (French NGO), with Gaiachain (UK blockchain firm)
CTA (Technical Centre for Agricultural and Rural Cooperation), EU financing; around €80,000, as one of four winners of a 2018 call on blockchain in agriculture
Cocoa / agricultural supply chain
Mé region, Côte d’Ivoire (villages of Diasson, Mébifon, and Biéby)
Producteurs de cacao biologique de la Mé (PCBM), an organic cocoa cooperative
A blockchain traceability app (built with Gaiachain), GPS plot mapping, and on-site field data capture
Pilot ran 2019 to 2020; assessment published May 2020
161 cooperative members; 306 hectares mapped; around 500 kg of cocoa traced from harvest to port
Proved blockchain can give organic cocoa a verifiable origin at micro level, and was candid that smallholders need more digital readiness and that mobile payments could not be properly tested
Cocoa is one of Côte d’Ivoire’s most important exports, and one of its hardest products to trace. Yields are low, and the supply chain is long and fragmented. Fraud over the quality of organic cocoa is common as well, in large part because there has rarely been a reliable way to follow a bag of beans from a specific farm to the port.
In 2019, a French NGO set out to test whether blockchain could change that for a single cooperative of organic growers.
The project, Cocoblock, was led by Nitidae with the blockchain firm Gaiachain and funding from CTA. The pilot was small, tracing around 500 kg of cocoa from one cooperative, yet its published assessment is unusually honest. It reported what blockchain did well and stayed candid about what did not work and what smallholders would need before the technology could scale.
For anyone weighing field-data traceability in a developing-country supply chain, that candour is worth more than a polished success story.
Here’s a breakdown of that project, from start to finish.
The Challenge: Proving Where the Cocoa Came From
Côte d’Ivoire is the world’s largest cocoa producer, and the crop is central to its economy. The sector also carries a stubborn set of problems: on one had, low yields; on the other, fraud over the quality of organic cocoa.
Both problems are fuelled by the lack of an effective traceability system. Organic and sustainably grown beans earn a premium, but without a credible origin record, conventional cocoa can be passed off as organic, which erodes the premium and the trust behind it.
The chain itself makes this hard. It runs through many smallholders, intermediaries, cooperatives, and exporters, and much of it has been recorded on paper or not at all.
Capturing reliable data at the first mile, the farm and the cooperative, is the part that has always been missing.
Since Cocoblock ran, the stakes have risen sharply. The EU Deforestation Regulation now requires that cocoa placed on the EU market be traceable to the precise plot where it was grown, with due diligence proving the land was not deforested after the end of 2020 and that production was legal.
Those obligations apply from 30 December 2026 for large and medium operators, and from 30 June 2027 for micro and small operators, and a cooperative in a non-EU country that places products on the EU market is itself treated as an operator that must file due diligence.
For thousands of smallholders, plot-level data capture has shifted from a nice-to-have to a condition of market access, which is exactly the problem Cocoblock was an early attempt to solve.
The Solution: Mapping a Value Chain onto a Blockchain
Nitidae’s approach was to record a real cocoa value chain, from harvest to port, and write the key stages to a blockchain so the origin record could not be rewritten later.
The cooperative and the plots
The pilot worked with the Producteurs de cacao biologique de la Mé (PCBM), an organic cocoa cooperative in the Mé region. It involved 161 members across three villages, Diasson, Mébifon, and Biéby, and mapped 306 hectares of plots. Mapping the plots gave each batch of cocoa a defined origin, which is the foundation everything else builds on.
Capturing the value chain
Working with Gaiachain, Nitidae built a traceability application that recorded the key stages of the chain from harvest to port and wrote that data to a blockchain. Farmers were trained on site and ran the system under real conditions, tracing almost 500 kg of cocoa through the pilot. The goal was a record that could limit fraud, lower transaction costs, and protect the premium that organic, traceable cocoa can command.
What the blockchain added
The blockchain’s role was to make the origin record hard to alter after the fact. Once harvest, aggregation, and shipment data were entered, the chain held a tamper-resistant history a buyer could rely on, which Nitidae later described as a dependable guarantee of controlled origin. The value here was trust, in a sector where quality claims are easy to make and hard to verify.
Mobile payments
The pilot also tried to test automatic mobile payments to farmers, on the theory that a digital transaction record could make payment faster and cleaner. This part never got a fair test. Mobile-money use in the area was limited and the trial was short, so the payment feature stayed a prototype rather than a working module, a point worth holding onto for the results below.
The Results: Clear Proof-of-Concept, But With Honest Limits
Within its admittedly small scope, Cocoblock did what it set out to do. It showed that blockchain can deliver better traceability for organic cocoa at the level of individual farms and batches, with 161 farmers, 306 hectares, and around 500 kg of cocoa traced from harvest to port. Nitidae’s assessment confirmed the core point: the technology can provide a dependable record of where cocoa came from.
The assessment was just as clear about the limits, and the biggest was readiness. Nitidae concluded that smallholders will need a greater level of digital maturity before they can adopt the practices the technology depends on, and that a cooperative has to digitalise its basic information systems, the way it records purchases and sales, before a blockchain can usefully sit on top of them.
What’s worth noting is that the real difficulty was the everyday data capture; the blockchain was the straightforward part.
Additionally, the mobile-payment component did not really work in the pilot. Low mobile-money penetration in the region and the short duration of the trial meant the feature could not be properly tested, and it stayed a prototype.
The lesson is narrower than it first looks: a data-collection pilot is not a payments rollout, and attaching an unproven payment flow to a traceability trial stretched the project thin.
Scale was the third limit. The pilot proved the idea at a micro level, and Nitidae was candid that there was a long way to go before the approach could work across the wider value chain, which would mean involving wholesalers, larger agri-food buyers, and financial institutions rather than one cooperative.
The honest summary was that the cocoa sector itself remained undecided, even as the traceability case held up.
Key Takeaways
The clearest lesson is that in a smallholder supply chain, traceability succeeds or fails on the data capture. Cocoblock’s blockchain worked; what needed more time was getting reliable, structured data out of the field in the first place.
Readiness has to be built before the technology lands. Nitidae found that farmers and cooperatives needed more digital maturity, and that the cooperative’s own record-keeping had to be digitalised first.
Simply put, training and a simple, usable capture process have to come first.
Connectivity is another key factor in shaping what is possible. The payment feature stalled partly because mobile networks and mobile money were thin on the ground, a reminder that any tool meant for rural fieldwork has to assume patchy or absent connectivity rather than treat it as an edge case.
Scope discipline also matters. Cocoblock reached for traceability and payments at once, and the payment side suffered for it. Proving one workflow well is usually worth more than half-proving two.
Finally, verifiable origin is now a market-access question, not only an ethical one. What Cocoblock piloted voluntarily in 2019 is close to what the EU Deforestation Regulation now requires for cocoa entering the EU, which makes plot-level, verifiable field data something exporters and cooperatives can no longer treat as optional.
How to Build Verifiable Field Records with VerusTrust Forms
Cocoblock’s lesson points straight at the layer VerusTrust Forms is built for: capturing reliable, structured, plot-level data from smallholders in the field, often with poor connectivity, and then proving that data has not been altered.
The features below map onto the specific places Cocoblock struggled, and where a data-collection tool cannot help, this case says so plainly.
This is the most direct fit. VerusTrust Forms captures records with no connectivity and syncs when a connection returns, so field teams and farmers can record harvests and plot data in villages and fields where coverage is thin, or even completely absent. Cocoblock ran into exactly this constraint; designing for offline-first capture removes it as a blocker.
VerusTrust Forms can capture geospatial data and geotag a submission using the device’s GPS, so every plot, harvest, or inspection carries its coordinates. That is the plot mapping Cocoblock did across 306 hectares, and it is now the core of what the EU Deforestation Regulation requires: high-precision geolocation linking cocoa to the land it grew on.
VerusTrust Forms can anchor a cryptographic hash of each record to a public blockchain, giving the same tamper-evidence Cocoblock was after: proof that an origin record existed and has not changed. The data itself stays encrypted on your account, and only the fingerprint goes on-chain. That way a cooperative gets a verifiable record without publishing sensitive farmer or commercial data.
A cocoa chain involves farmers, cooperative staff, NGO coordinators, and buyers. Forms controls who can submit, edit, and approve, which keeps the chain of custody clean as records pass between parties and gives a coordinator a single view across the cooperative.
Simple capture with zero technical requirements
Cocoblock’s central finding was that smallholders needed more digital maturity. A simple, structured form lowers that barrier: Forms lets you build a short, guided form, and the AI Form Builder can draft one from a plain-language description, so a field agent or farmer records only what is needed in a few taps.
This reduces the technical hurdle, but it does not remove the need for on-the-ground training and support. Forms makes capture easier; it does not replace the capacity-building Nitidae rightly insisted on.
What VerusTrust Forms does not do
The boundary is worth stating. Forms is a field data collection platform, not a payments system. The mobile-payment problem Cocoblock hit is a financial-inclusion and connectivity issue that a data tool does not solve.
What Forms can do is supply the clean, verifiable origin and transaction records that a separate payment or finance system would need to work from.

Start Building Verifiable Blockchain Records with VerusTrust Forms
Cocoblock is a useful case precisely because it did not oversell itself. It proved that blockchain can give cocoa a dependable, verifiable origin, and it was honest that the real work sits in the field: capturing clean, plot-level data from smallholders who need simple tools and genuine support, often without a reliable signal.
Years on, that work is no longer optional for anyone exporting cocoa to Europe, because the EU Deforestation Regulation has turned verifiable, geolocated origin data into a condition of market access. The cooperatives and exporters that treat field data capture as core infrastructure, rather than a last-minute compliance scramble, will be the ones ready for it.
That capture layer is what VerusTrust Forms exists to provide, and you can start your own pilot run today.
Design a form, capture data in the field, and anchor each submission to a public blockchain so anyone can verify it later.
Blockchain verification is included on every VerusTrust Forms plan, including the affordable Starter tier.
