AdEx vs Facebook Ads: What are the differences?
What is AdEx? An open-source, transparent & fraud-proof display advertising. It is trust-minimized solution for digital advertising that reduces ad fraud, improves ad budgets and protects user privacy. It is built on the Ethereum blockchain to connect publishers and advertisers without intermediaries on a decentralized ad exchange.
What is Facebook Ads? Social network advertising. It is targeted to users based on their location, demographic, and profile information. Many of these options are only available.
AdEx and Facebook Ads can be primarily classified as "Advertising" tools.
