Advertisements have always been a fundamentally weak proposition. They are intrusive, tangential, privacy invasive, and distract from the cleanliness of a website.
Making matters worse, creative content publishers are suffering due to the advent of ad blockers and a general disregard to what advertisements have to offer.
Website visitors contribute a small portion of their CPU and GPU power to enable users' files to be stored on a decentralized and anonymous ledger.
In return, the website owners get paid indirectly by the storage users and website visitors can enjoy an ad-free browsing experience.
