The advent of digital advertising has made the marketing of products very flexible these days. Digital advertising has created a breakthrough, expanding the boundaries of marketing. But this digital advertising can also be considered as a double-edged sword; nothing is permanent. As one bad experience can ruin the hole image of the company with celebrities like Facebook, Twitter, Instagram, etcetera. To avoid this disaster, the content should be secured and reliable. To assure that security, blockchain came into view redefining digital advertising.

With blockchain partnering with digital advertising, the content is secure as the information stored in a block can be repeated million times but never altered providing a secure share even when it travels all over the world. With its chain-like configuration and unbreakable security features, blockchain is gaining traction in digital marketing. It can block all the fake impressions. For instance, some companies use artificial learning and machine learning to multiply the number of views which can be stopped using certain complex algorithms of the blockchain. More importantly, blockchain eliminates the intervention of the third person and provides a direct contact with the website owner to sign an agreement or any official business. Since all the transactions are done in open, it assures reliability for everyone.
