Build 'BlocAI'—a decentralized, AI-driven blocking and moderation tool for social platforms. Uses federated learning to identify and block unwanted accounts based on community consensus. Includes a 'Trust Network' where users can share and validate blocking lists.

Users on decentralized social platforms struggle with unwanted interactions from controversial or government-affiliated accounts. Current blocking mechanisms are manual and inefficient, leading to poor user experiences and platform reputational risks.
