Somebody could try to build own crawler and feed them with 260MM domain names dataset from https://domains-index.com

Is there more like this? Afaik SSL certificates are required to be committed to an open ledger but I can't find anywhere to obtain the ledger..

Maybe you're referring to Certificate Transparency Logs ? There's background info at http://www.certificate-transparency.org/what-is-ct

You could implement your own log monitor or use services like crt.sh or certstream to build a candidate list of domains that have registered SSL certs.
