Cardano is a great payment method. Its stated aim is “to bring about positive global change”, and that is what Mass Adoption is all about!

Launched in 2015 by a Hong Kong company named IOHK, it’s an open-source, decentralized project that uses proof-of-stake transaction validation. Compared to Bitcoin’s 7 transactions a second, Cardano can achieve 1000 per second.

Cardano and Environment: Cardano Sustainability

You cannot mine Cardano, hence the miniscule energy use. ADA can be staked instead of that. You can accept Cardano payments and keep them in a Cardano wallet, receiving a certain percentage for that. This is what “Proof of Stake” is and that is what makes Cardano sustainable.

How it works

So, like already mentioned above, Cardano uses a ‘Proof of Stake’ consensus mechanism. To join the network, participants buy tokens. Thus, an enormous amount of energy is saved. According to the founder of Cardano, the network uses only 6 GWh of power, which aims to provide a sustainable eco-system.


Cardano aims to fix a lot of challenges of the modern world, and ADA being a sustainable payment method is an inspiring opportunity for businesses and more, with a lot of use cases it got.
