Cardano is a third-generation blockchain platform that was founded in 2017 by Charles Hoskinson. Hoskinson is a co-founder of Ethereum, and he left Ethereum in 2015 due to disagreements with the project's direction.

Cardano is designed to be more scalable, secure, and energy-efficient than previous blockchain platforms. It is based on a proof-of-stake (PoS) consensus mechanism, which is less energy-intensive than the proof-of-work (PoW) consensus mechanism used by Bitcoin and Ethereum.

The native token of the Cardano network is ADA. ADA can be used to pay for transactions on the Cardano network, and it can also be staked to earn rewards.


Charles Hoskinson is an entrepreneur and software engineer. He co-founded Ethereum in 2015, but he left the project in 2015 due to disagreements with the project's direction.

Hoskinson then founded IOHK, a research and development company that is focused on developing Cardano. IOHK is also the company that is responsible for maintaining the Cardano network.

The name "Cardano" is a reference to Gerolamo Cardano, an Italian mathematician and philosopher who lived in the 16th century. Cardano was a pioneer in the field of cryptography, and he is credited with inventing the concept of a "cryptocoin."

Purpose of ADA

The ADA token is used to pay for transactions on the Cardano network. It can also be staked to earn rewards. ADA is also used to participate in governance of the Cardano network.

Cardano's Blockchain and Ecosystem

The Cardano blockchain is based on a unique proof-of-stake (PoS) consensus mechanism called Ouroboros. Ouroboros is a more energy-efficient and scalable consensus mechanism than the proof-of-work (PoW) consensus mechanism used by Bitcoin and Ethereum.

The Cardano ecosystem is rapidly growing. There are now over 1,000 dApps running on the network, and the number is growing all the time. Cardano is also a popular choice for DeFi projects.

Cardano Roadmap and Its Upgrades

The Cardano roadmap is divided into five phases:

  • Shelley: This phase was launched in 2020, and it introduced the PoS consensus mechanism to the Cardano network.
  • Goguen: This phase is currently underway, and it will introduce smart contracts to the Cardano network.
  • Basho: This phase is scheduled to be launched in 2022, and it will focus on scalability and performance improvements.
  • Voltaire: This phase is scheduled to be launched in 2023, and it will introduce on-chain governance to the Cardano network.
  • Mary: This phase was launched in 2021, and it introduced native tokens to the Cardano network.


Cardano has been involved in a few controversies. In 2017, the project was accused of plagiarising parts of its white paper. However, the allegations were later found to be unfounded.

In 2021, Cardano was criticised for its slow development progress. However, the project has since made significant progress, and it is now one of the most active blockchain platforms in the world.


Cardano is a popular choice for dApps and DeFi projects, and it is growing rapidly. The project is now one of the most active blockchain platforms in the world, and it is likely to continue to grow in the future.
