Please describe your proposed solution.

<u>Problem:</u>

Currently, e-commerce plays an indispensable role in people's lives, with almost everyone making purchases on e-commerce platforms. However, these platforms still face several significant issues:

• E-commerce platforms concentrate substantial power in the hands of leading organizations. They have the authority to delist products or delete buyer data if there are issues that need resolution, potentially leading to unhealthy competition and negatively impacting buyer rights.
• Sellers on e-commerce platforms may incur high shipping costs when buyers fail to pay for their purchased products.
• Buyers find it challenging to reclaim funds when they receive low-quality products from unreliable sellers.
• The absence of cryptocurrency payment options limits access to secure and decentralized payment methods.

<u>Solution:</u>

We are establishing a decentralized e-commerce platform on the Cardano blockchain. This platform aims to:

• Be the world's first decentralized e-commerce platform.
• Allow buyers to make direct payments on the platform using ADA or Cardano-based stablecoins.
• Manage buyer and seller activities through Smart Contracts on Cardano.

<u>How Smart Contracts will manage the buying process:</u>

When a buyer places an order on the e-commerce platform, they will have to lock the equivalent amount of ADA (or stablecoin) into a Smart Contract, matching the product's price. This Smart Contract will connect with an Oracle to obtain shipping data from a reputable and verified shipping company. The Oracle will continuously update the shipping information. Sellers will also have to lock the shipping cost into a Smart Contract with the shipping company. After the order reaches the buyer, the buyer will confirm receipt in the Smart Contract, and the funds will be transferred to the seller's wallet. Simultaneously, the shipping company will notify a second Smart Contract of the successful delivery, and the payment will be transferred to the shipping company's wallet.

For other cases such as buyers not receiving the product due to personal issues, buyers not receiving the product, or sellers delivering low-quality products, we will construct specific conditions in Smart Contracts to ensure the resolution of these issues.

These are some typical use cases for utilizing Smart Contracts to create a decentralized e-commerce platform without the need for centralized management. We will continue researching and developing a complete Proof-Of-Concept for this solution, detailing the system's operational flows and creating a prototype for the e-commerce platform.

Please define the positive impact your project will have on the wider Cardano community.

Our solution has the potential to bring hundreds of millions of users to Cardano, considering the massive user base of current e-commerce platforms (billions of users). This is an exceedingly crucial application for today's users. Furthermore, integrating Cardano blockchain into e-commerce can significantly boost transaction volumes on Cardano, given that e-commerce platforms typically handle substantial daily transaction volumes.

We are providing an outstanding utility for Cardano users. People can conveniently buy and sell goods using ADA. Users have complete autonomy in decision-making and personal information management, and issues in purchasing are automatically resolved through Smart Contracts.

Our solution aims to minimize risks in buying, selling, and shipping in current e-commerce, thereby enhancing the overall user experience. The complete open-sourcing of our project's code allows other projects to use and develop their related applications.

This initiative not only addresses current challenges in e-commerce but also contributes to the broader adoption and utilization of blockchain technology, particularly on the Cardano platform. It aligns with the principles of decentralization, transparency, and user empowerment. As the project progresses, it will be fascinating to see how it evolves and contributes to the growing ecosystem of blockchain-based solutions.

How does the cost of the project represent value for money for the Cardano ecosystem?

Information about developers' salaries in Vietnam ranging from $1,500 to $3,000 USD is valuable for assessing the project's costs. Paying developers within this salary range is considered reasonable and quite competitive globally, especially when compared to developer salaries in developed countries.

This project not only benefits Cardano but also has the potential to attract hundreds of millions of users with a demand for buying and selling on e-commerce platforms. This can increase the demand for the ADA coin, adding value and stability to it.

Moreover, the project contributes significantly to the increase in transaction volume on Cardano. With the substantial transaction volume from e-commerce platforms, Cardano could become a popular blockchain platform for e-commerce transactions.

For ADA holders, this project provides additional utilities and value for their ADA holdings, creating an ecosystem that the community can enjoy and contribute to the development of Cardano.
