QuestN is a Web3 task certificate platform built for B-end users that has evolved significantly by 2025. In the same field, most mainstream task certificate platforms such as RabbitHole and Galxe only allow B-end clients of a certain scale to post tasks through platform filtering. However, since its launch, QuestN has set no threshold, allowing entities like KOLs, communities, and DAOs to post tasks. By 2025, the platform has expanded to 185 million registered accounts, 7.3 million NFTs minted, and supports 28 blockchains. QuestN now features AI-driven task recommendations, a token-gated task system, cross-chain reward distribution, and sophisticated analytics tools for business users. The platform's Soulbound Token system has evolved into a comprehensive reputation framework functioning as a portable Web3 resume. QuestN has implemented community-governed task creation mechanisms and enhanced educational components with progressive difficulty levels. Through strategic partnerships with Layer 2 solutions, digital identity providers, and educational institutions, QuestN has positioned itself as essential infrastructure in the Web3 ecosystem rather than just a marketing tool. Previously known as Quest3, the platform, along with its name change, has transformed from a simple task platform into a learning ecosystem creating valuable interactions that benefit all stakeholders.
