One of thing that I find annoying in various decentralized identities is that in 99.99% cases or more it is some awful unreadable meaningless opaque string (obviously either public key or its hash).
Humanity should create more meaningful (human-friendly) form of decentralized identies, that likely could be visualized as some "contact card", optionally with image, with name, and e. g. qr code or other representation of cryptographic material. ⬇️
