NFTs as Cookie Alternatives

  • First-party cookies are stored within the domain that the user is visiting. The web server sends pieces of data to the browser, and on each subsequent visit to the site, the browser sends them back to the server. So, if you are for example on the website, all cookies stored under this domain are considered first-party cookies. These cookies are usually used to identify the user when switching between pages of the site, to remember the settings selected for the site, or — on online shopping sites — to store items added to the shopping cart. It’s hard to find a website that does not use first-party cookies nowadays as 1st party cookies are now used by almost all websites.
  • You may have already guessed that a third-party cookie is a cookie created by a different domain than the one you are visiting. Let’s say and another site you’ve been visiting have agreed to serve ads to their users. Ads come from one provider whose code is hosted on both domains. When you visit a website, the provider creates a third-party tracking cookie. When you visit other sites, they recognize you by cookies and display the same ads. Essentially, they track your online behavior by building your profile for targeting purposes. No wonder, 3rd party cookies are also known as tracking cookies.
  • Second-party cookies are a questionable topic. Some people might say they don’t exist at all. In general, second-party data is some first-party data shared between partners. In this sense, second-party cookies are just part of that data related to cookies.
