In the current digital age, our personal identities are owned and controlled by large corporations and governments, often leading to data breaches and a loss of privacy. Decentralized identity is a new model where individuals own and manage their own digital credentials on a blockchain. This allows a person to prove their identity, their educational qualifications, or their employment history without needing a central authority to vouch for them. When you want to sign up for a service or prove your age, you can share a digital proof without revealing all of your personal data. This “self-sovereign identity” puts the power back in the hands of the individual and reduces the risk of identity theft, as there is no central database for hackers to attack. As more of our lives move online, having a secure and private way to manage our digital selves will become one of the most important applications of blockchain technology.
