Digital Identity on a Blockchain Platform

The purpose of this research paper is to examine the fundamentals of blockchain technology and how the application of blockchain could serve as a future platform for identity. An identity is used, as the name suggests, to identify who or what an entity is. Although seen as a trivial concept, defining what truly makes up an identity can become quite difficult. Is an identity the thoughts, feelings, or tendencies of a person? Are more tangible assets like a Social Security card, birth certificate, or passport a person’s identity? Can nonhuman entities like businesses or organizations possess an identity? The true definition of an identity may never be known; however, it is certain that several pieces of identifying data lay scattered across multiple databases. Often a person may not have control or even access to these third-party databases that hold their information. Moreover, what information, for how long, and in what way the data is being used may be unclear. Blockchain provides a solution to the identity problem by providing a visible, secure single source of truth. On a blockchain platform, a person would no longer have to trust the goodwill of third parties to secure their data or be uncertain about how the data is being used. Instead, a user could secure their own data and only permission those deemed necessary. The signal immutable ledger would serve to replace current tangible identities as a means to verify yourself in a digital age.
