<u>Detailed Problem:</u>
Agri-food systems are under enormous pressure. By 2050, the world's population is expected to increase to an estimated 9.7 billion.[1] Feeding the population will require increasing current food production in the context of climate change and unsustainable exploitation of natural resources.
To meet this challenge, agrifood systems must become more productive, transparent and sustainable, small farmers will have to adopt new production processes and, in turn, deal with limited access to information, financial services and formal markets.
Smallholder farmers often receive only a small fraction of the final market value of their production. Inequalities such as these manifest themselves in extreme poverty among farmers, as well as on-farm human rights abuses in the form of slavery, child labor and hazardous work environments.[2] [3]
Current agri-food systems exert undue pressures on the environment. Agri-food supply chains contribute 26% of greenhouse gasses while using 50% of habitable land and 70% of freshwater. In addition, agriculture is the largest contributor to biodiversity loss on Earth.[4]
The integrity of agri-food supply chains is often compromised by food safety incidents resulting from adulteration, dilution, tampering or counterfeiting. Food fraud results in damages of up to $40 billion annually. Worse, the source of the problem is often not easily identifiable given the opacity of supply chains.[5]
The above issues underscore the common challenge of ensuring traceability and transparency in agri-food supply chains.
What are the problems with the current solutions?
Blockchain has been adopted in the food system and traceability and brings many advantages for provenance, compliance, authenticity and quality. However most of the applications are permissioned and mostly at the benefits of a private owner or consortium. This information asymmetry is particularly damaging for smallholders that have no advantage on this system and have to adopt the retailer system. Data cannot contribute to building and sharing a common and efficient data model. This model is crucial to make the agriculture model more efficient and reduce the food system environmental impact . Data cooperation and governance can be a direct source of income and social benefits, and an impact on researchers that cannot reuse and improve food security models, study sustainability or carbon emission without relying on private companies.
Blockchain contribution to food security.
Food system creates valuable information that is essential for food security and plays a major role in the economic growth of countries. Because food growing is a complex process and that food is processed between the farmer and the consumer, food data is not yet effectively collected and used to improve the sustainability of the food system..
Blockchain is a foundational technology (FT) that can create a more secure environment to secure data with multiple participants. (Lakhani and Iansiti 2017). Blockchain have been successfully implemented in numerous agriculture domains:
The above solutions use private or consortium federated blockchain which are permissioned. The main drawback of the permissioned system is centralization thus does not allow public adoption. Moreover this system prevents researchers from evaluating this system and verifying the alignment with imminent climate challenges.
Research studies have shown that using blockchain-related systems in the food chain improves the transparency and traceability, the safety, the sustainability, the cybersecurity and resilience. Blockchain has found a way in the agrofood supply chain and data management structures in improving the consensus between participants.
Many efforts have been made to develop food traceability and safety of agriculture with permissioned systems, such as private consortium blockchain that are centrally coordinated, with access granted only to participating entities. Food buyers and public research then have to rely on centralized actors to access information making the system highly centralized and not resilient. Food data information is fragmented due to the centralization and asymmetries of the agrofood supply chain thus data is poorly distributed.
This fragmentation is also due to incompatibility issues between supply chain and blockchain (Nurgazina et al. 2021). Since large amounts of data are generated along the food value chain it is necessary to generate data that are easy to handle and compatible between all the stakeholders. For example, to analyze food life cycle researchers require to study data from farm to production so data need to keep quality and consistency among the all life cycle , (Zeb, Soininen, and Sozer 2021).
However, little research work has been made to bridge the different blockchain solutions in a food product-centered manner that integrates all the active stakeholders . These efforts are crucial to preserve food data integrity through the food life cycle and create data workflow, carbon emission and sustainability models that can be more accurate. More effort can be the deployed to incentivize and track small farmers to produce with more sustainable practice (Wilson 2018), (Sylvester and Others 2019) and participant will be able to verify the food information (Mehrabi et al. 2020) and collaborate (Hernandez, Mortimer, and Panetto 2021) to take more conscious decision.
<u>Detailed solution:</u>
We are developing a traceability platform based on Cardano's Blockchain technology. This platform has the function of digitizing the agri-food supply chain to make traceability and compliance with safety and sustainability standards and certifications an integral part of the production processes of small farmers.
The user will be able to record and share authentic information from each stage of the chain, starting with producers at the first mile, improve food safety, strengthen brand integrity, increase consumer confidence and monitor environmental impact as well as good agricultural practices and social conditions in the producing communities.
Small farmer cooperatives and organizations will be able to monitor production yields, facilitate third-party certification processes, access formal markets, and build a digital economic identity that allows them to access various financial services.
Stakeholders:
Initially, the user profile of the platform will be those who have or seek to establish supply relationships with small farmers.
The user profile of the platform is one who has an interest in :
- Reduce high transaction costs in contract farming agreements.
- Reduce operational complexity in the supply of small producers.
- Communicate practices related to sustainability and protection of human rights.
- Facilitate food safety and sustainability certification processes.
Normally processors, cooperatives and exporters meet this profile, but they can also be national and multinational corporations or startups in agricultural e-commerce.
The platform will be very useful for track products and to prevent counterfeit items.
This solution can help multiple stakeholders for several purposes:
-
The certification can reinforce the geographical indication goods and ensure the respect of “Products specifications” as provided for the EU regulation.
-
For food producers it can help avoid counterfeiting of products and be proof of sustainable production.
-
By using tokens for food labeling and traceability systems can enforce the hygiene requirement (e.g. maintenance cold chain) facilitates traceability (article 18 General Food Law*) and the recall (article 19 GFL).
Tecnology overview.
Cardano native tokens.
The solution lies in a permissionless non-fungible and fungible tokens that store verified food related information with a non hierarchical trust system. Through multiple applications including food identity and provenance. The decentralized system can help for food transparency, decentralized trust and peer to peer transactions thus reducing the monopolistic position of intermediaries.
Cardano is part of the third generation of blockchain. Via the extended unspent transaction output (EUTxO) Model, Cardano blockchain allows the implementation of minting policy at the creation of the token. Cardano also allows abstractions of transactions thus allowing to add metadata to the transactions. At the first stage of token creation, minting, the information that is stored in the token file and metadata are now saved into the blockchain with a transaction signed with a wallet.
Cardano uses PolicyID to protect the minting and modification of the token. The PolicyID is a 24 words seed phrase that creates a hash and defines the token minting policy. Cardano policy ID can be used to directly identify the token issuer since the seed phrase is really hard to recover from the hash.
Another particularity of Cardano system is the use of staking addresses and receiver/sender addresses that belong to the same wallet. This unique staking address can be retrieved from receiver and sender addresses.
Tokens bound.
Native tokens can be linked to create a more complex system of relation. A non-fungible token of a certification can be directly bound to the fungible token of a food product via a metadata bound that can attest the product quality, certification, test, origin that serve as proof.
This bound is encoded and specialised to understand the link between tokens. For example, FoodOn ontology used “certified”, “has part”, “has quality” to qualify relation between elements. The token policy ID will serve to identify the token provider efficiently thus policyID must come from a third party certification recognized by stakeholders in order to create trust on the document and on the product.
This decentralized system can integrate fungible tokens to represent food units linked to the verified non-fungible tokens. Since the non-fungible token was verified by a third party and is locked by the minting policy then fungible token will refer to verified non fungible tokens.
How will the solution work?
At the harvest time the food producers will mint a quantity of fungible token proportional to the food harvested. While trading food with a processor or retailers through the food supply flow, the asset can be sent to the next stakeholder wallet that can in turn send it to another stakeholder. Moreover, stakeholders will be able to submit metadata in the transaction such as the previous transaction or the delivery. This system can serve as an online reference to keep data integrity along all the supply chain processes.
Transaction metadata can efficiently report the operation made on a product and follow a standard for interoperability along the supply chain. Following a standard this metadata could describe product transformation (physical/ chemical changes), contain information generated by IoT about the product environment (light,temperature,humidity) or transport (vehicules,location, duration) shared between stakeholders. The transaction metadata content can also point to a private server or contain a hash of the information to maintain privacy.
At the product transformation, the process should also be stored in metadata bound and obey to a metadata standard. The burning transaction of the token refers to the policyID of the manufactured product. The manufactured product will be bound with the raw material (part/parent) token (such as “as part”) by referring to the token burning transaction. Part tokens will be burned and the manufactured token will be produced in stoichiometric quantity. These two mechanisms will protect information integrity during the product transformation.
CropTrace platform enables communication and trust over product information and offers a transparent traceability solution. Tokens will protect the product information integrity and certification in a metadata structure, preserve the distribution stoichiometry (1 token = 1 unit of food) and can be synchronized in every ecommerce and ERP database at the same time. Every end consumer will be able to check for product information saved on the blockchain.
This public information can be used by consumers to make social and environmental buying decisions. Finally tokens can help for the data interoperability and connection between food databases to liberate this information and create an immutable backbone for food traceability safer, more open and universally accessible.
Why is a traceability daap important for the Cardano ecosystem?
There are factors that drive the adoption of a traceability platform for the agri-food sector such as:
-
Consumers are increasingly aware of the importance of environmental sustainability and labor standards during the production process of agri-food products. More than 71% of consumers worldwide are willing to pay more for brands that provide transparent information.[6]
-
Adoption of third-party certification standards (e.g., Rainforest Alliance, Forest Stewardship Council, B Corporation) can demonstrate companies' commitment to responsible production.[7]
-
The legislative framework, certifications and standardizations drive the adoption of modern traceability systems due to the strict guidelines of regulatory bodies related to food safety in several developed and developing countries.[8]
Why is our solution better ?
Our solution offers a permissionless blockchain based approach that makes reliable data accessible for multiple parties thus can reliably protect the food data security system. Food information can then be reused along the food product lifecycle even after processing for public or private stakeholder.
Then hierarchical governance can be replaced by a role based structure that enables participation, scalability, and technological innovation. The decentralized blockchain structure and consensus mechanism will maintain multi version control of data in a decentralized way and available for everyone. Using a permissionless network, cryptocurrencies payment can accelerate incentive for the food product and sustainability, buyers can use cryptocurrencies to buy the food product directly, governments, NGO can also periodically reward farmers based on the certification they own on their products.
How does this solution add value to Cardano's ecosystem?
Our main output is the deployment of the platform with traceability functionality, since we plan to use native tokens, it will drastically reduce the complexity of operating and implementing the blockchain technology, so we expect an adoption by the agricultural supply chain stakeholders.
As a result, it is expected to attract new users to the ecosystem, the creation of new wallets, native token minitng and payments of agricultural assets with ada or djed.
Our solution lies in the construction of food related tokens to build a comprehensive food that can efficiently be shared between all stakeholders and be used for their applications. This token can represent material resources ( food, land, water, seed, equipment) and immaterial resources (trust, knowledge) related to the food system that are also referred to as ‘commons’ [9]. This token can also be used for food analysis and commercial usages.

Please describe how your proposed solution will address the Challenge that you have submitted it in.
<u>Use case that impacts and facilitates adoption.</u>
Given the evident need for a modern information system that provides traceability and transparency to the world's agri-food systems, it can be said with certainty that the creation of this daap is a use case that impacts not only the Cardano ecosystem but also the lives of millions of people, which translates into greater adoption thanks to the low level of complexity in the proposed implementation.
<u>Type of proposal.</u>
The proposal fits into the Transport and Logistics category.
Transport and Logistics.
Trace food products and by-products.
Traceability is the ability to record and keep history of a product from the production to consumption while answering “when, where, whom?”.
The transactions stored on the blockchain possess unique addresses. Blockchain helps to store the product trace by keeping the information on the ledger by the physical owner of the asset. This authentication brings more certainty and interoperability on the data stored about the asset, in turn that becomes more valuable.
The user will scan a tag (QR Code or NFC) applied on a product to access its traceability information stored on the blockchain. By verifying information stakeholders are involved in anti counterfeiting products, verifying the trace and preventing them from harmful fake products.
Native tokens help for products to be synchronized to one different database by querying the same blockchain. Using metadata data standards in token and transaction, tokens improve the interoperability between database and application. It removes the cost of data architecture and development making the blockchain traceability more accessible.
Tokens can be support product traceability. At the product transfer, the transaction differentiate a batch of products from another batch, thus every batch of products can be identified by a unique transaction, from the most recent transaction, a token can be traced back to the minting transaction, allowing a product auditability.
This unique latest transaction can be integrated in a QR code for any stakeholder to check the physical product traceability. All Stakeholders are identified by their wallets staking address or policyID. To help this identification a system based on users wallet should allow them to add information to clarify the role of every participant in the supply chain and enforce transparency and auditability.
Prevent counterfeit items.
By using metadata safety and quality control regulators and blockchain analysis tools will be able to observe the complete history of a token from farm to fork. This information could accelerate the search for a safety issue such as mycotoxins for example. In case of a safety issue, safety agencies can emit a warning on non fungible tokens that will be displayed if someone scans the product QR code of this batch.
Trust system encompasses food certificates, quality control and hazard alerts. This category of resource is the first requirement for consumer health protection. Food producers notably smallholders food labelling is first important for farm identity [1],[2]) and consumer trust. Token can help for human and machine food certificate verification by saving a digital certificate pointing to a digital asset of food product parcel and land certification. Third party verification will make sure about food producer specific claims about a food production parcel notably.

What are the main risks that could prevent you from delivering the project successfully and please explain how you will mitigate each risk?
<u>Challenges impeding the adoption of blockchain traceability systems.</u>
-
Digital adoption, most smallholder farmers live in rural areas of developing countries, where there is a lack of access to internet and other digital infrastructure, as well as digital illiteracy.
-
There is a lack of incentives for farmers to collect data, and one element that is currently missing is the need for a business model for data collection that includes the technology and support activities to make implementation viable, which is fundamental to ensure the sustainability of the model for small farmers.
<u>How are we going to deal with these challenges? </u>
The use of Cardano native tokens and metadata in transactions reduces much of the complexity in the implementation of blockchain traceability systems, for example it is not necessary to use smart contracts in the issuance of non-fungible tokens.
The platform is designed in a way that is friendly to new users, especially since most of the stakeholders to whom the platform is addressed are not familiar with the technology.
Despite being able to develop the platform in a robust way, it has been decided to use low code tools within the cardano ecosystem such as Joget, a solution for companies and startups that allows to create applications in cardano in a very fast, simple and cost efficient way. This will allow us to design the product focusing on the user experience.
Regarding the incentives to small producers for data collection, we and agribusinesses need to carry out an education campaign to communicate to producers the benefits they will have:
-
Third party certifications (organic, environmental, fair trade, etc).
-
Access to formal markets, this information system will facilitate the supply from small producers.
-
Increased income by being able to demonstrate sustainable practices.
-
Construction of economic identity to access financial services in the future.
