On-chain social protocols can establish trust rating systems to replace traditional social verification. By leveraging blockchain's decentralization, transparency, and immutability, these protocols create tamper-proof reputation scores based on user interactions, verified identities, and transaction histories. Smart contracts automate trust scoring, eliminating biases and intermediaries. Unlike centralized platforms prone to manipulation, on-chain systems ensure data integrity and portability, allowing users to carry reputations across platforms. Privacy-preserving techniques like zero-knowledge proofs balance transparency with confidentiality. Such systems foster secure, reliable interactions in decentralized social networks, addressing trust issues in online communities.
