Solana ID as a new attempt at identity recognition infrastructure shows a lot of potential in the field of advertising targeting. This system allows users to establish verifiable identity profiles on-chain while maintaining certain privacy controls — an interesting improvement direction for the digital advertising ecosystem.

Compared to traditional centralized ad tracking, blockchain-based identity systems give users greater control over their data. Advertisers can target more precisely, and users can have more transparency about how their data is used. This balance could reshape marketing patterns in the Web3 era. The Solana ecosystem's exploration in this type of infrastructure is attracting more attention.
