Where the claims sound clean but fall apart the moment you actually stress test them.

I went into $SIGN expecting to find that gap pretty quickly.
What surprised me is that the more I pulled, the less it came apart.

The dual blockchain design is not an afterthought. The private Hyperledger layer handling sensitive government operations separately from the public chain is a deliberate response to exactly the metadata problem that ZK proofs alone do not fully solve. 🔐
The deployments are more real than most. Sierra Leone did not announce a pilot. They launched live national digital ID infrastructure. UAE deployed, not announced. That distinction matters more than people realize.

The weak point I did find is the sovereignty tension. When systems share infrastructure, whoever shapes the recognition standards quietly accumulates influence no one formally granted them. That is a real question. The technology alone cannot fully resolve it.
But that is a tension built into shared infrastructure itself — not a failure of execution.
