Web3 Reputation and Escrow Infrastructure for Social Influencer Campaigns on ICP

This paper introduces B4B.app, a Web3 influencer marketing protocol that leverages the Internet Computer (ICP) to solve persistent industry challenges such as fragmented data, unreliable ratings, and payment disputes. B4B.app delivers a trustless, cross-chain infrastructure combining influencer discovery, campaign management, and secure escrow payments in one seamless platform. At its core, B4B-ICP acts as a reputation and settlement layer, aggregating performance data from multiple social platforms and ensuring transparent, on-chain record keeping. This paper presents the platform’s architecture, user workflow, and implementation stack, along with key milestones and planned enhancements, including EVM interoperability and AI-driven performance prediction.
