Federated identity stores are like music CDs: large troves of data to be consumed from a single source. Self-sovereign identity is like streaming: share just what you want, just when it's needed. In a recent discussion we had, Marie Wallace shared a wonderful analogy for verifiable credentials. I think it helps with understanding how credentials will be adopted. She compares traditional approaches to identity and newer, decentralized approaches to the move from music CDs to streaming. I'm old enough to remember the hubbub around file sharing. As this short video on Napster shows, the real winner in the fight against piracy was Apple and, ultimately, other streaming services:
Nice analogy!
