The Power of Digital Identity: How Blockchain Certifications are Changing the Game

A blockchain-based digital identity is a self-sovereign identity (SSI) that you own and control. Unlike traditional systems where your personal data is stored on centralized servers (think of your social security number or driver's license stored in a government database), a blockchain identity gives you the keys to your own information. Instead of a single authority holding all your data, a decentralized identifier (DID) is created. This unique identifier is linked to a public key on the blockchain, and all of your credentials—like a college degree, a professional certification, or even a medical record—are issued and cryptographically signed by the original issuer. You, and only you, hold the private key to this information, storing it securely in a digital wallet.
