The emergence of decentralized applications, know as dApps – a new form of applications based on blockchain technology – offers a huge opportunity to establish an entirely new decentralized, trustful market for advertising. These applications operate autonomously, openly and accessible to all. What’s more, dApps offer previously unimaginable imperviousness to any kind of central point of failure attacks. Carefully designed dApps fulfill exact requirements regarding user data privacy, availability and reliability that allow informational and monetary exchanges between users, creating an unprecedented level of security and trust available through open source code and consensus algorithms to perform critical functions. Projects like Ethereum8 and Blockstack9 have had significant success in developing the dApps ecosystem that is already rapidly evolving. In the coming years, thousands of new dApps will appear and they will require a dedicated advertising ecosystem for monetization.
