DID stands for Decentralized Identifier, which is a digital identity framework that uses blockchain technology to create unique, verifiable identifications for individuals, entities, and things. The main idea behind DID is to provide a secure, decentralized way for people to control their digital identities without relying on central authorities, such as governments or social media companies. With DID, individuals can store their identity information in a distributed ledger that is accessible only to them and their authorized parties. These IDs can be used for a variety of applications, including financial transactions, healthcare, voting systems, and more. The DID framework is still in its early stages of development, but it has the potential to revolutionize the way people manage their online identities and data privacy.
