Sorry you lost me on blockain. Also IF any blockchain were to be used to persist stuff like this it's the biggest, most decentralized.

Corda is a special blockchain,it's based on need-to-know basis system. It means you can host your own node, and share your data only to the peers you want.

What happens if your node catches on fire before you share anything?
