Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

Certificate Transparency (CT) is an Internet security standard for monitoring and auditing the issuance of digital certificates.[1] The standard creates a system of public logs that seek to eventually record all certificates issued by publicly trusted certificate authorities, allowing efficient identification of mistakenly or maliciously issued certificates.[2] Version 2.0 of the Certificate Transparency mechanism, the latest, is described in the experimental RFC 9162, which obsoletes the earlier version 1.0 described in RFC 6962.
