Just because you can solve your problems with a blockchain, doesn't mean you should - Zulfikar Ramzan.

L33tdawg: Sounds like essentially what Amber Baldet said in her closing keynote at #HITB2018AMS

While the world rushes to slap a blockchain onto a growing number of applications to generate hype and excitement, RSA CTO Zulfikar Ramzan has told ZDNet that he is not convinced that many use cases of blockchain couldn't be addressed by more traditional mechanisms, such as a database.

"For example, we talk about like supply chain management, people tout that as a very classic blockchain use case," he said. "But to me, that seems like that's a shared database use case -- and you know, it's funny because people who don't understand the security nuances don't understand why a database is not worse than a blockchain, in fact I think in many cases it is better."

Ramzan said that in many cases, blockchain is a "heavy duty model" designed to address problems with a lack of trust, but often the solution has a number of trust assumptions built in. For instance, in the case of tracking an object, the process for assigning identifiers and adding the identifers to the blockchain need to be trusted.
