One of the most costly problems for the government is mistakenly granting subsidies to the wrong people.
It is possible for a person to receive funds twice from two different agencies because the database is not connected. And @SignOfficial resolves this through identity-linked distribution, meaning that each time the budget is disbursed, it is checked against the on-chain ID, so one cannot receive funds twice from two sources. TokenTable has implemented this mechanism for over 40 million wallets already.
Now the question is which government will trust enough to use $SIGN ?
