Problem Statement
Modern online applications and marketing relies heavily on advertising (see following figure), which has several major challenges:
User identities are managed by individual web applications. User experience is fragmented. Worst, users have little control over their web identity and footprint data in Web2 services.
User data is owned by technology giants with poor reputations for privacy protection, and brand marketing uses inferred data.
Even for tech giants, data loss and breaches occur frequently, arousing distrust in users.
Pay-per-click advertising has a low conversion rate, leading to high customer acquisition costs.
Users are increasingly requesting cookie-less web experiences, which will further impact marketers’ ability to reach target users.

Web3 identities with on-chain credentials offer a promising solution to address privacy and data breaches, but adoption is hindered by poor user experience. Other challenges include limited user control, scalability and integrability issues, security vulnerabilities, regulatory uncertainty, and high cost and complexity of NFT/token minting and trading.
