I think this needs to be provided by the government: an organisation that we already have to trust and already has a monopoly. Countries that get this sorted out will see their economies grow. Countries like the UK where people continue to believe that sending scans of utility bills is a good basis for a modern economy and somehow prevents money laundering will continue to go down the toilet.
There are plenty of studies and case studies that show this to be true, it's a necessity that government given identity should also exist digitally. It's rather insane it doesn't yet in the states.
