ok fine, since you asked
1. cash = self-authenticating ✅, trust travels with banknote, no need to check with government to re-spend. trillions in value stored and transferred because of this special property 💝
2. ID card = not self-authenticating ❌, must check with official state/country DB to see if it’s actually real. fake IDs = multi-billion dollar problem
3. ID card, sealed w/ blockring = self-authenticating ✅, trust travels with payload, no backing network required, immutable, tamper-proof, quantum-ready. identity fraud solved 💝
(blockring sealing works with any type of data, ID example is just the easiest for ppl to understand)
