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.

A history of impossible, made possible

Use Cases
Benefits

Cardano restores trust to global systems – creating, through science, a more secure, transparent, and sustainable foundation for individuals to transact and exchange, systems to govern, and enterprises to grow.

Cardano brings a new standard in technology – open and inclusive – to challenge the old and activate a new age of sustainable, globally-distributed innovation.

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 the Cardano network’s decentralization, and allows it to sustainably scale to global requirements without, crucially, compromising security.

The protocol is the culmination of tireless effort, building on foundational research, and is propelled by a vision for more secure and transparent global payment systems, and a means to redistribute, more fairly, power and control.

Discover Cardano

Cardano is the first blockchain platform to be built through peer-reviewed research, to be secure enough to protect the data of billions, scalable enough to accommodate global systems, and robust enough to support foundational change.

We have changed science. We have changed what it means to build global systems and sustainable models of exchange and governance.

We, alongside our community and partners, are defining a new future: a decentralized future without intermediaries, in which power is returned to the individual.

Partners

A decentralized team works across three independent entities to ensure that Cardano stays true to its purpose as we advance and evolve.
