Is it an insane idea to incorporate the blockchain technology into the current PKI system so that every time a CA signs a key it must insert a new transaction into the blockchain which links it to the certificate? We could have a full, transparent and cryptographically secure certificate log.

In my country, receipts systems are actually required to implement hash chaining to allow the authorities to detect "missing" receipts (for tax-avoidance control purposes).
