Consulted in the space about 3 years ago. Regulatory powers lack tooth. Most large banks are not ready (i.e. poor security, complex backend, no scalability, etc.) and are scrambling to find solutions while begging for my time. Also, lots of discussion and jostling and fear of what might happen when it goes live. No one can truly agree on the legal framework as well so feels like much work to be done.

Was also part of the implementation phase in the UK and the regulatory powers there definitely sped things up.
