Their insights have been instrumental in shaping the project’s direction. CT plays an important role in the Web PKI, enhancing the ability to monitor and research certificate issuance.

For instance, Let’s Encrypt issues over four million certificates daily, each of which must be logged in two separate CT logs. Our well-established “Oak” log currently holds over 700 million entries, reflecting the significant scale of these challenges. In this post, we’ll explore the motivation behind Sunlight and how its design aims to improve the robustness and diversity of the CT ecosystem, while also improvi
