Security features on blockchain are also important. For example, PayPal is only a secure software technology for currency transfer but it does not mint or mine any currency (fiat or virtual). In the same way, blockchain uses security measures to transfer both currency and information securely. However, if hackers want to attack the blockchain then it would be nearly impossible to do without any detection because the blockchain is one giant ledger. Change one digit or letter and it shows. If an organization holds its secure information in a database or cloud based service, there is some possibility of a hack without any detection for months or even years. See recent examples of Yahoo and Marriott. One took place years ago while the other happened only a few months prior.

Blockchain can also transfer information and not every transaction has to be the "value added" type. I recently attended an AMA that explored other applications of blockchain including use of decentralized apps (or dapps) for businesses to send and receive private information. In my country, healthcare information is held to high privacy and confidentiality standards that even some SaaS cannot meet. Tokenization of said information on the blockchain could solve this problem. The startups at the AMA did not go into details. However we can store regular purchases of needed medications in the blockchain then there are some uses for people who need regular heart or diabetes medications. Sure there are payments involved for the medication from insurance companies but what about the patient's information? Blockchain can also store and transfer this information.
