Blockchain technology does not require a license, and the stored data cannot be modified. In addition, it is fast, simple and quite secure. No one has the foresight to desist from seeing the importance of this technology. All these economic sectors are looking for a safe haven and are incorporating blockchain technology into their operations.
It is interesting and useful:

• It helps in tracing drugs
• It helps in keeping patient document (data) safe
• It provides electronic health record and better clinical trials.

I agree with you
