AdX.so is a next generation decentralized ad exchange and ad network, built on a use-case optimized SVM. The model enables realtime (encrypted blind auction) bidding to serve targeted digital ads to a website or application's audience. The whole process is proven back to the Solana L1 for validation and settlement between advertisers and publishers. Our hackathon submission focused on the SVM and exchange model at the centre of network. The broader vision is to also develop next generation solutions for identity, attribution and targeting. Doing so in a way that is privacy preserving and enabling data self-sovereignty, and for individuals to participate in the value created. We believe audience/end-users should be able to participate in the network's value creation throug opt-in for targeting and ad serving, for example through DePIN/Grass-inspired browser plugin
