Buy Cardano

Cardano (ADA) is a decentralised blockchain platform designed to run apps and smart contracts using a research-driven, energy-efficient approach. Its native cryptocurrency is called ADA.

It helps to separate two names that are sometimes confused. Cardano is the blockchain platform, while ADA is the cryptocurrency that powers it. ADA is named after Ada Lovelace, a 19th-century mathematician often regarded as the first computer programmer.

Like Ethereum, Cardano is a programmable blockchain that supports smart contracts, which are pieces of code that automatically run when certain conditions are met. Developers use it to build decentralised applications across areas such as decentralised finance (DeFi), identity and tokenised assets. Cardano is known for its focus on peer-reviewed research and a methodical, evidence-based development process.

What is Cardano used for?

Cardano is used to run decentralised applications and to transfer value across its network. ADA is the asset used to pay transaction fees and to take part in securing the network, as well as interacting with apps built on Cardano.

Cardano runs on a Proof-of-Stake system called Ouroboros. Instead of mining, holders can stake their ADA to help validate transactions and secure the network, and in return may earn staking rewards. This approach is designed to use far less energy than mining-based blockchains.

Cardano has a fixed maximum supply of 45 billion ADA. Because the supply is capped, no ADA can be created beyond that limit, although not all of it is in circulation yet. New ADA enters circulation gradually according to the network's rules.

The history of Cardano

Cardano was launched in September 2017 and was co-founded by Charles Hoskinson, who was also an early co-founder of Ethereum. It was built by a team of engineers and academics with the goal of creating a more scalable, secure and sustainable blockchain.

A defining feature of Cardano is its scientific approach. Its design is based on peer-reviewed academic research, and development is split across several organisations that maintain the protocol and support its growth. You can find out more on the official Cardano website.

Since launching, Cardano has grown into one of the largest blockchain platforms in the world, particularly associated with Proof of Stake and a careful, research-led development style. People buy ADA for many reasons, including using Cardano applications, staking, paying network fees, or gaining exposure to the Cardano ecosystem.
