Qiwi

Inspiration

Traditional loyalty programs face significant challenges such as inefficiency, insecurity, and high operational costs. Many existing programs struggle with transparency, leading to a lack of trust among customers regarding the sourcing and production of rewards. Additionally, the environmental impact of these rewards is often overlooked. Inspired by the potential of blockchain technology to address these issues, we set out to create Qiwi. Our goal is to provide a secure, efficient, and transparent loyalty program that not only improves customer engagement but also promotes sustainability and ethical sourcing.

What it Does

Qiwi offers a comprehensive loyalty program where businesses can issue, transfer, and redeem points called Qiwi Qoins. The program ensures secure and tamper-proof transactions using blockchain technology, eliminating the risk of fraud and manipulation. It also tracks the ethical and sustainable sourcing of rewards, providing transparency to customers about the origins and environmental impact of the rewards they redeem. The easy-to-use web interface enhances the user experience for both businesses and customers, making it simple to manage and utilize loyalty points.

Key functionalities include:

Issuance of Qiwi Qoins: Businesses can easily issue loyalty points to customers based on their transactions and interactions.

Transfer of Qiwi Qoins: Customers can transfer points to each other, fostering a community-driven loyalty program.

Redemption of Qiwi Qoins: Customers can redeem points for a variety of rewards, with detailed information about the sustainability of each reward.

Sustainability Tracking: Each reward's sourcing and production process is tracked on the blockchain, ensuring transparency and accountability.

How We Built It

We developed Qiwi using a robust and modern technology stack that ensures both performance and security. Our approach included:

Backend: We wrote smart contracts in Solidity to handle the issuance, transfer, and redemption of Qiwi Qoins. These contracts are deployed on the Metis Layer 2 blockchain, which offers the benefits of scalability and low transaction fees.

Frontend: Our web interface is built using Next.js, providing a responsive and dynamic user experience. The interface is designed to be intuitive for both business users and customers, making it easy to interact with the loyalty program.

Blockchain Integration: We used Web3.js to connect the frontend with the blockchain, enabling seamless interaction with the smart contracts. This integration ensures that all transactions are secure and recorded on the blockchain.

Tools: We utilized Hardhat for developing, testing, and deploying our smart contracts. Hardhat's comprehensive tooling allowed us to streamline the development process and ensure our contracts were robust and secure. MetaMask is used for managing user accounts and facilitating transactions, providing a user-friendly interface for interacting with the blockchain.

Challenges We Ran Into

Developing a blockchain-based loyalty program presented several challenges. One significant challenge was ensuring seamless integration between the frontend and the blockchain. This required careful handling of asynchronous operations and managing user sessions securely. Testing the smart contracts thoroughly to ensure they were free of bugs and vulnerabilities was another critical challenge. Additionally, implementing sustainability tracking required extensive research to ensure we accurately represented the sourcing and production processes of rewards.

We also faced challenges in optimizing the performance of our solution to handle potentially high volumes of transactions without compromising security or user experience. Balancing these requirements was a complex task that required innovative solutions and rigorous testing.

Accomplishments That We're Proud Of

We are proud of several key accomplishments in developing Qiwi. First and foremost, we successfully created a fully functional blockchain-based loyalty program that integrates seamlessly with the Metis Layer 2 blockchain. Our smart contracts are robust and secure, ensuring that all transactions are tamper-proof.

We are also proud of our sustainability tracking feature, which provides transparency and accountability for the rewards offered through the program. This feature aligns with our goal of promoting ethical and sustainable consumer practices. Additionally, we developed a user-friendly web interface that makes it easy for businesses and customers to interact with the loyalty program, enhancing overall user experience.

Our solution demonstrates the potential of blockchain technology to transform traditional loyalty programs, making them more efficient, secure, and trustworthy.

What We Learned

Throughout the development of Qiwi, we gained valuable insights into blockchain technology and smart contract development. We learned how to effectively use Hardhat for testing and deploying contracts, ensuring our solution was secure and reliable. Integrating Web3.js with our frontend provided us with a deep understanding of how to connect blockchain applications with user interfaces.

We also learned the importance of thorough testing and security audits to identify and address potential vulnerabilities. Our experience with sustainability tracking taught us how to accurately represent the environmental impact of products and services on the blockchain, providing valuable transparency to consumers.

Additionally, we gained experience in optimizing the performance of blockchain applications, ensuring they can handle high volumes of transactions efficiently.

What's Next?

Our future plans for Qiwi include expanding the rewards catalog and integrating more businesses into the program. We aim to enhance the platform by adding mobile app support, allowing users to manage their loyalty points on the go. Advanced analytics features will provide businesses with valuable insights into customer behavior and program performance, enabling them to optimize their loyalty strategies.

We also plan to introduce personalized rewards, tailoring the program to individual customer preferences. Collaborating with sustainability certifiers and blockchain auditors will further improve the transparency and trustworthiness of our solution. Additionally, we will explore partnerships with other blockchain projects and platforms to expand Qiwi's reach and impact.
