Blockchains are being used increasingly because of their immutability. In April 2020, during the COVID‐19 pandemic, IBM used blockchains to help the health‐care industry.

If I am a supplier and I create a profile and include my information for onboarding as a new supplier, there's a qualification process I have to go through… It is done to determine if they are legitimate, ethical, that they comply with required laws and, in this case, with needed FDA certifications.” [Wei20].
