TrustBuddy
Trustpilot but for People (Telegram/Twitter/LinkedIn) to reward trust and avoid scammers.
Demo
About
- Every day, millions of people receive unsolicited DMs on Twitter, LinkedIn, and Telegram, making it nearly impossible to know whether the person reaching out is genuine or a scammer (an issue even Vitalik highlighted during his keynote). - TrustBuddy tackles this problem by offering a decentralized reputation system across Telegram/Twitter/LinkedIn where users can verify their social handles, leave honest reviews, and check others’ trustworthiness before ever responding to a message. - By combining on-chain reviews, zero-knowledge social proofs, and secure randomness for reward gamification, TrustBuddy empowers users to spot scammers, reward genuine interactions, and build a safer, more transparent online community across the platforms where trust matters most.
How it's made
- Built using Scaffold-ETH 2 for rapid dApp prototyping with a Next.js React frontend and Solidity smart contracts. - Core smart contract deployed on the Flare Coston2 testnet, taking advantage of Flare’s secure on-chain RNG to gamify TBT (Trust Buddy Token) rewards for reviews. - Integrated vlayer’s zk Web Proofs to cryptographically verify users’ Twitter handles, ensuring that only authentic social identities can be reviewed. - Each review submission triggers a Blockscout link for full transparency, allowing users to instantly verify on-chain transactions; the contract is verified and publicly accessible on Blockscout. - Implemented a dynamic reward mechanism where the amount of TBT earned per review is determined randomly via Flare’s RNG, adding an engaging and fair gamification layer.
