Blockchain is a solid argument given what happened to #equifax incident. The financial and healthcare world, along with anyone managing other’s PII and financial records should be required (or incentivized) to implement a distributed, decentralized, #blockhain database of information coupled with your typical industry best practice layered security model.
Imagine a world where #blockchain is implemented as a standard such as those of the OSI model. From applications, to database, to updates, to authentication. Where everything is audited by everything else on the same peer level of network or devices. Where IoTs can be secured at its peer level of devices, same with databases, storage, peer to peer, financial, healthcare, PII data, supply chains, contract reconciliations and the list goes on and on.
