Market-on-Chain Built with Chainlink

A DeFi supply chain solution for a fairtrade peer-to-peer token economy using Chainlink's blockchain middleware platform and Oracles to pull product information from multiple off-chain data sources.

Comment

Inspiration

We envision a world where individuals and businesses can sell goods and services they own, make or build in a peer-to-peer token economy with Chainlink's secure blockchain middleware using Oracles that act as a bridge between smart contracts and off-chain data feeds. We want to empower underrepresented people and economies worldwide with our peer-to-peer fairtrade blockchain marketplace. We are a global team and have traveled and lived in many countries where the local communities and families will benefit from our solution. We are diverse and inclusive. We have two women on our team.

What it does

Our project is a Frontend Market-on-Chain dApp and supply chain inventory management solution using Chainlink Oracles to pull in product information from multiple off-chain data sources including:

  • GS1 US Data Hub Universal Product Code (UPC) The United States, Canada, the United Kingdom, Australia, New Zealand, and many other countries generally use barcodes known as Universal Product Codes (UPCs).

  • Global Trade Identifier (GTIN13) The GTIN is a globally unique 14-digit number used to identify trade items, products, or services. GTIN is also an umbrella term that refers to the entire family of UCC. International Article Number (EAN) & EAN13 (European Article Number an extension of UPC) Merchants in Europe and other areas around the world often use a barcode type known as an International Article Number (EAN, since it was formerly known as European Article Number).

  • International Standard Book Number (ISBN) Books often use the International Standard Book Number (ISBN) barcode format, which is compatible with EAN barcodes.

  • Amazon (ASIN) Amazon Standard Identification Number (ASIN) is a ten-digit alphanumeric code that identifies products on Amazon. It's unique for each product and is assigned when you create a new product in Amazon's catalog.

And many more.... Our solution also aims to support custom off-chain data sources to create custom QR-Codes with information for the product or good using a non-fungible-tokens (NFT) for DApps running on Chainlink.

How we built it

Frontend: React, javascript, HTML Contract: Solidity Backend: Chainlink & Testnet

Challenges we ran into

Latency with transactions on Testnet

Accomplishments that we're proud of

We are a global team that uses our time, talent, and passion to develop solutions for social impact using emerging technologies.

What we learned

We learned how to use Oracles for pulling data off-chain from multiple data sources that follow international standards for product information that enables trading with partners around the world. We also learned how to incorporate the production details into our Smart Contract using Chainlink platform features and their Testnet. We researched supply chain use cases for blockchain and developed our solution from personal experience and the desire to foster innovation, entrepreneurship, and social impact.

What's next for Market-on-Chain

We are submitting our project for Chainlink Community Social Impact Grant to continue building our solution on Chainlink to enable a peer-to-peer fairtrade blockchain marketplace for financial inclusion to empower underrepresented people and economies worldwide. We believe in diversity and inclusion. Our global and diverse team is led by a woman, who has expertise in identity and cybersecurity.
