Double-blind review is a reviewing process in academic conferences or journals for submitted papers where the ideintities of authors and reviewers should remain anonymous for each other. An alternative adopted instead of the double-blind review is single-blind review where the reviewers know the authors but the reviewers' identities remain anonymous for authors.
One of the most important thing for double-blind reiview is that, as an author, you should not reveal your identities in any manner, e.g., using "in our previous work [1]" in the Related Work or including your source code or dataset link with a URL might contain your identity information (e.g., link to your shared Drive with some of your information can be disclosed).
An interesting solution discovered recently is adding the link http://www.omitted.link/ for the reviewing process and simply replace the link later with actual link. For example, in the latex of your article:
\footnote{\url{http://www.omitted.link/}}
Specifically, the link will point to a dummy page with the following information:
