B4B.World Demo: Influencer Marketing Cross-Chain Platform

This demo addresses the challenges of creating influencer marketing campaigns, including difficulties in measuring campaign performance and payment risks. Blockchain technology can provide a solution by offering reliable influencer profile generation, transparent reputation models, and template escrow payments. However, communication and processing of payments across ecosystems remain a challenge for Web3 projects. The paper presents B4B.World, an influencer marketing platform that utilizes cross-chain smart contract calls and supports payments in multiple blockchains. The platform offers reputation-based rewards for influencers and allows advertisers to make campaigns using crypto assets or project-based NFTs. B4B.World is the winner both The Illuminate/22 Hack by Moonbeam and BNB Chain Hackathon 23 in Georgia and utilizes the Axelar platform for cross-chain interaction.
