The problem Stackchain solves

The decentralized version of Stack Overflow solves the problem of centralized platforms controlling user data and content. By utilizing a decentralized network, the platform ensures that all user data and questions are saved forever and cannot be censored by a centralized authority. The platform also solves the issue of unreliable server uptime as it is fully decentralized, ensuring near-zero downtime. Additionally, the platform implements a skill assessment system based on popular upvotes and the difficulty of questions solved, providing an accurate representation of users' expertise. With these features, the decentralized version of Stack Overflow provides a reliable, censorship-resistant, and accurate platform for developers to seek and share knowledge. It can also act as a hiring platform as it is fully decentralized.
