This will get interesting for many CT transparency monitors which for many are already seeing scalability issues.

I am operating https://www.merklemap.com/ and the current scale is already impressive.

I don't know much about CT requirements, but can't they prune data out of their logs after some time? Since the certs only last 6 days, the growth of the logs can be capped at some point right? If not now, provisions for such operations could surely be implemented, I imagine.

PS. Neat site!

    That's what happens - logs are "expired" after a few years. But if you want to have an exhaustive monitor, you probably don't want to discard the records of expired certificates.

    Thank you!

Hmm, I wonder if it's possible to do dedicated intermediate certificates that promise to only sign short-lived certificates for a single site? That way the CT-log could be taught to only keep the intermediate?
