How Web3 Will Change the Future of Digital Advertising

The digital advertising industry functions as the backbone of the Web2 internet, heavily influenced by major players like Google and Meta. This sector generates billions in revenue through a model that relies on surveillance. Companies provide "free" services in exchange for the ability to track user behavior, compile data profiles, and sell attention to advertisers. The rise of Web3 challenges this approach, promoting user ownership, privacy, and decentralization. This shift signals a potential transformation in digital advertising, emphasizing consent and direct value exchange.

Flaws in the Web2 Advertising Model

The current advertising framework suffers from several critical issues:

• Surveillance Capitalism: Platforms track online activities to create detailed user profiles, leading to significant privacy invasions.
• Data Ownership: Users do not own their data; it resides with the platforms, allowing a few corporations to dominate the market and suppress competition.
• Transparency Issues: The advertising supply chain lacks clarity. Advertisers often cannot trace where their funds go, and publishers are unaware of their actual earnings.
• User Exploitation: Users are not viewed as customers but products. Platforms prioritize engagement over user needs, creating misaligned interests.

Web3's User-Centric Advertising Model

Web3 introduces a new advertising framework centered around user control over data and attention.

1. Ownership of Data and Privacy-Focused Advertising

In Web3, users maintain control over their data through their crypto wallet. This change supports an advertising model that prioritizes user privacy.

• Mechanism: Advertisers pay users for permission to access their data or to display advertisements. Users dictate what data is shared and with whom.
• Example: The Brave browser exemplifies this model. It blocks conventional ads and trackers by default. Users can choose to view privacy-oriented ads and receive Basic Attention Token (BAT) rewards for their attention. This token can be used to support content creators or exchanged for other benefits.

2. Zero-Knowledge Proofs for Privacy-Respecting Targeting

Zero-Knowledge Proofs (ZKPs) enable advertisers to target users without accessing their personal data.

• Mechanism: For instance, an advertiser may wish to target users over the age of 21 living in California. In Web2, they would purchase this information from brokers. In Web3, a user can generate a ZKP with their decentralized identity, proving they meet the criteria without disclosing their actual age or location.
• Benefits: This approach allows precise ad targeting while maintaining user privacy.

3. Direct Monetization for Creators

Web3 enables creators to earn revenue directly from their audiences, minimizing reliance on traditional advertising.

• Mechanism: Through NFTs and token-gated content, creators can establish sustainable income streams from dedicated fans.
• Benefits: This builds a healthier relationship between creators and their communities, encouraging the production of high-quality content over clickbait.

Challenges Ahead

Transitioning to a Web3 advertising model poses significant challenges. Established Web2 companies will resist changes that threaten their dominance. the user experience of managing data permissions and engaging with crypto systems must improve for widespread adoption.

Nevertheless, the trend toward enhanced privacy is evident. Regulations like GDPR and Apple's App Tracking Transparency are already challenging the traditional surveillance model. Web3 offers a technological framework for a new advertising model built on user consent, respect for privacy, and equitable value distribution across the internet. For marketers, the future will focus on rewarding users for their attention rather than tracking them.
