Arrayán

Arrayán stands as a revolutionary web application, seamlessly integrated with the Resilient DB blockchain fabric. Designed to empower industries, Arrayán facilitates comprehensive tracking of products, by-products, and their historical journey throughout the supply chain. The platform champions transparency, aiding food organizations in effortlessly visualizing information from farm to retail. Our mission with Arrayán extends beyond mere tracking; we aim to redefine traceability for sustainability. Notably, the platform introduces a key feature allowing consumers and other industry sectors to claim food by-products - stems, peels, and seeds. This forward-thinking approach not only fosters transparency but also encourages the responsible use of by-products. This reclaimed data on generation times and methods becomes invaluable. It opens doors for scaling the utilization of these by-products, transforming them into raw materials for extracting valuable molecules for cosmetics and generating hydrogen - two prized assets in today’s dynamic economy. Arrayán is not just a tool for tracking; it’s a catalyst for sustainable innovation and resource optimization.

Problem Identified

Scientific evidence supports the potential of food by-products as valuable sources of molecules for the cosmetic industry. However, their utilization has been limited as the chemical composition and yield variability are influenced by factors such as variety, environmental conditions, and the methods of cultivation and processing. Currently, there is a lack of comprehensive traceability for most by-products, hindering the recording of crucial data. This absence of information results in a lack of standardization, contributing to uncertain yields and increased costs associated with the extraction and purification processes. A parallel challenge is observed in the use of by-products for hydrogen production and other upcycling applications.

Solution

This web application plays a pivotal role in meticulously tracing the generation of by-products at each stage. This granular information is instrumental in standardizing by-products, facilitating their upcycling on a larger scale, and pinpointing key areas where substantial amounts of by-products are produced. Our traceability-for-sustainability model not only offers a blueprint for companies to embrace circular economy models but also ensures compliance with regulations such as the Food Safety Modernization Act. The primary objective of the Food Safety Modernization Act is to enhance food safety. In the event of a foodborne incident, rapid tracking within 24 hours is mandated. The regulation emphasizes the necessity for companies to share information seamlessly across their supply chain, and blockchain emerges as a powerful tool to streamline this process. Arrayán stands as more than just a tracing tool; it is a catalyst for the food industry to not only meet regulatory requirements but also to potentially increase profitability from their by-products and reduce its environmental footprint. During the development of the application, we established a partnership with the teaching and research winery of UC Davis. To kick-start our journey, we are delivering a Proof of Concept utilizing the data generously provided by our collaborators.

Note: Arrayán also aligns with Senate Bill 1883, offering a pathway to compliance with this additional regulation.

Steps to run the system

Download NodeJS from here and ensure that it’s added to PATH.

Clone the repo of arrayan to get started:

git clone https://github.com/Amoolya-Reddy/arrayan.git

Then navigate inside the ResVault directory:

cd arrayan

Install the dependencies:

npm install

Start the project:

npm start

Build the project:

npm run build

The above code uses online instance of Resilient DB and the application is ready to be launched. For further exploration, below steps can be followed to setup and play around with local instance.

Setup Python3.10

Ensure you have Python3.10, otherwise download it and set it up as default.

Setup ResilientDB

You will need to clone the ResilientDB repo to get started:

git clone https://github.com/resilientdb/resilientdb.git

Then navigate inside the ResilientDB directory:

cd resilientdb

Install dependencies:

sh INSTALL.sh

Run ResilientDB KV Service (this may take a few minutes for the first time):

./service/tools/kv/server_tools/start_kv_service.sh

Setup Crow HTTP server, SDK, and GraphQL server

You will need to clone the ResilientDB GraphQL repo to get started:

git clone https://github.com/Amoolya-Reddy/ResilientDB-GraphQL

Then navigate inside the ResilientDBGraphQL directory:

cd ResilientDB-GraphQL

Install the Crow dependencies:

sudo apt update sudo apt install build-essential sudo apt install python3.10-dev sudo apt install apt-transport-https curl gnupg

Build Crow HTTP server (this may take a few minutes for the first time):

bazel build service/http_server:crow_service_main

Start the Crow HTTP server:

bazel-bin/service/http_server/crow_service_main service/tools/config/interface/service.config service/http_server/server_config.config

Create virtual environment for the Python SDK:

python3 -m venv venv –without-pip

Activate the virtual environment:

source venv/bin/activate

Install pip in the virtual environment for the Python dependencies:

curl https://bootstrap.pypa.io/get-pip.py | python

Install the Python dependencies:

pip install -r requirements.txt
