4. Future of Blockchain

Digital Identity

Today, we use passwords and authentication questions to prove who we are online. Blockchain could replace this system with a digital identity that is safe, secure, and easy to manage.

Instead of proving who you are by recalling some personal, arbitrary piece of information that could potentially be guessed or stolen, your digital identity is based on the uniquely random set of numbers assigned to each user on a blockchain network.

This means your identity can’t be hacked or changed without access to your private key, which makes it exponentially more reliable than our current solution. In fact, the National Institution for Standards and Technology (NIST) is already investigating how blockchain can help protect digital identities.
