Our World Is Changing. Together, We Can Change It For The Better.
Cardano is a proof-of-stake blockchain platform: the first to be founded on peer-reviewed research and developed through evidence-based methods. It combines pioneering technologies to provide unparalleled security and sustainability to decentralized applications, systems, and societies.
With a leading team of engineers, Cardano exists to redistribute power from unaccountable structures to the margins – to individuals – and be an enabling force for positive change and progress.

Proof-Of-Stake And Ouroboros: The Most Environmentally Sustainable Blockchain Protocol
Ouroboros is the first peer-reviewed, verifiably-secure blockchain protocol, and Cardano is the first blockchain to implement it. Ouroboros enables decentralization in the Cardano network on a sustainable scale for global requirements and most crucially, without compromising security.
The protocol is the result of tireless efforts, based on foundational research, propelled by a vision for more secure and transparent global payment systems, and provides the means to equitably redistribute power and control.
