The problem OpinioNect solves

1. In many online platforms, unique comments often get overshadowed by spam or repetitive comments, leading to a lack of diverse perspectives being highlighted.
2. Ensuring that all voices are heard and given equal weight, especially on topics where multiple viewpoints are crucial for fostering understanding and progress.
3. Promoting social sustainability requires platforms that encourage inclusivity and respectful discourse, which can be hindered by comment sections dominated by a few voices.

Challenges we ran into

1. We faced some difficulty in connecting APIs and Wallet but overcome the situation by researching about the topics and applying the knowledge for practical results.
2. Integration of Smart Contract and React.js (Frontend) was a major hurdle but was solved through version manipulation.
