The first information about the upcoming start of a new crypto project called DATA appeared at the end of 2017. DATA is a blockchain-based advertising protocol and technological solution to the problem of fraudulent activities being the hardest challenge in the digital advertising industry. The DATA platform is developing advertising content optimization and strives to create a secure environment for direct interaction between advertisers, developers and consumers. Concurrently, advertisers should get a guarantee that their ads were viewed by the target audience, and users will get DTA tokens as a reward for viewing such ads. The emphasis is on creating a decentralized platform based on a reputation system and mutual trust.
