What is Cardano?

Cardano describes itself as (see link further below):

This is the first blockchain project to be developed from a scientific philosophy, and the only one to be designed and built by a global team of leading academics and engineers. It is essential that the technology is secure, flexible and scalable for use by many millions of users. Consequently, considerable thought and care from some of the leading experts in their fields has been devoted to the project and informed design decisions. The scientific rigour applied to mission-critical systems such as aerospace and banking has been brought to the field of cryptocurrencies, with a high assurance implementation. We believe this is the first time that this has been done.

A major innovation of Cardano is that it will balance the needs of users with those of regulators, and in doing so combine privacy with regulation. The vision for Cardano is that its new style of regulated computing will bring greater financial inclusion by providing open access for all to fair financial services.
