Your rating in Uber or Upwork is an illusion of ownership. Try transferring your "5 stars" to another platform. Spoiler: you can't. You'll get banned — and you are nobody. You do not own what you have earned.
I tested the SIGN mechanism at the activity certification level and see how they really aggregate between services. This is a different league. Each of your successful deals or professional skills is recorded as an on-chain certification.
What this means in practice:
Your reputation is no longer tied to a specific platform.
You transfer your "social capital" between any dApps.
It starts to really work for your wallet.
For example, you show a DeFi protocol your reliability certification and receive a lower % on an unsecured loan. Most people do not even realize that their reputation does not belong to them, and here it becomes your asset. If your reputation does not bring you money — you are still in the digital matrix.
