The Certificate Transparency (CT) ecosystem is a critical component of the Web Public Key Infrastructure (WebPKI), ensuring that all website certificates are publicly visible and auditable. CT was developed in response to the 2011 DigiNotar hacking incident, which highlighted the need for a more transparent and accountable certificate issuance process. The system involves public certification authorities (CAs) issuing certificates that are then logged by CT logs, which are maintained by organizations such as Cloudflare. These logs provide a publicly visible audit trail of all certificates issued, helping to protect users and website owners from mis-issued certificates. Despite its successes, the CT ecosystem faces challenges in maintaining integrity and availability, particularly with regards to scaling and performance. To address these issues, a new static CT API log design has been developed, which provides efficiency improvements and reduces the risk of integrity violations. This design is now being deployed by organizations such as Cloudflare and Let's Encrypt, and is expected to play a critical role in ensuring the security and trustworthiness of the web.
