To streamline user interactions, gas fees can be paid by the system account if a periodic allowance is granted to the user. Each of these transactions triggers real-time sorting of recommended posts, trending topics, categories, and communities, enabling dynamic content updates, with content quality measured by accumulated reputation scores. Inevitably, it introduces challenges including on-chain storage, token onboarding, Sybil resistance, indexing and sorting, and content moderation, which will be discussed in detail. TLOCK meets these challenges with a hybrid approach: a censorship-resistant on-chain core, plus an optional service layer—AI translation, auto-hashtags, human checks etc. —that improves UX without compromising the decentralized core. ### Quick Links Official Site: [https://tlock.org](https://tlock.org/) GitHub: X.com(Twitter): Telegram: Documentation: --- # Agent Instructions This documentation is published with GitBook.
