And if you do sell it, does that transaction preclude a right to privacy? The many forms of privacy have been highly debated in recent years and a mix of both technological and societal aspects have formed the basis of this debate. One area that is emerging is in the technical side around a concept known as a “decentralized identifier” or DID. The question is, are DIDs inherently privacy-enhancing, and can the use of DID as a protocol add privacy value to a system?
Decentralized identifiers: What is a DID?
Centralization of digital identities and identity attributes is something that we have all grown up with, from employee directories to government national security numbering systems, and so on. Typically, these identifiers are held in a central database or similar. Then the blockchain came along and offered a decentralized different way to handle identifiers. But the blockchain was an unfettered way of managing data exchanges as no standard underpinned these exchanges. That was until the W3C came along and developed
