Transparency logs are a powerful tool that makes it possible to bring accountability where it is unpractical to improve trust. Certificate Transparency pioneered and popularized the use of transparency logs, but also presents a model that is not very reusable due to its peculiar PKI context, and the technology has markedly improved since. In this talk we'll discuss the new designs, what properties they provide and when they are appropriate as a solution, how they are implemented, deployed, and scaled, and how they enable new transparency log applications, with plenty of real world examples.
