In the traditional peer review process, what is characteristic of a single-blind review?

In a single-blind review, the characteristic feature is that the identity of the author is revealed to the reviewer, while the author does not know who the reviewer is. This approach allows the reviewer to fully understand the context of the work and assess it without the potential biases that could arise from knowing the author's identity. The anonymity of the reviewer helps maintain an impartial evaluation of the work, as the authors are kept unaware of who is providing feedback. This process is designed to uphold the integrity of the peer review system while ensuring that authors can be evaluated based on the merit of their work without the influence of biases related to their identity.
