SocialBlock is a next-generation blockchain protocol that reimagines consensus by shifting power from token-based staking to AI-evaluated reputation. Designed as “The Reputation Chain,” it blends decentralized infrastructure with intelligent agent systems to score user credibility, track participation, and reward meaningful actions across the ecosystem. At its core is ARP (AI Reputation Proof), a hybrid consensus model that combines zero-knowledge identity (zkID), community validation, and AI-driven scoring to determine on-chain influence. Rather than relying solely on wealth or stake, SocialBlock empowers validators and users through verifiable social activity, contributions, and contextual trust. Built for the emerging world of AI agents, DAOs, and tokenized identity, SocialBlock includes a browser extension, real-time Explorer, live chatrooms, and modular developer tools to support a full SocialFi experience — where reputation becomes the ultimate form of capital.
