What is Cardano (ADA)?
Cardano is a third generation blockchain platform designed for decentralised applications and secure transfer of digital assets. It uses a multi layer architecture and a research driven approach to balance security, scalability and sustainability, with ADA as the native cryptocurrency that powers transactions, staking and governance on the network.
A purpose-driven platform
Cardano was created to address limitations seen in earlier blockchains, such as high energy consumption, limited throughput and difficulty upgrading. Its goal is to offer a more scalable, secure and sustainable platform for global financial applications. By using proof of stake and modular design, it aims to support real world use without sacrificing decentralisation.
Key components of Cardano
Cardano revolves around three main elements. ADA is the native cryptocurrency used for fees, staking and governance. The settlement layer records ADA transactions securely and efficiently. On top of this sits the smart contract layer, which runs decentralised applications and more complex logic while keeping core value transfers stable and reliable.
Smarter, greener Blockchain security
Cardano’s consensus mechanism, Ouroboros, selects block producers based on the amount of ADA they control and delegate, rather than raw computing power. This approach drastically reduces energy consumption compared with proof of work systems. It also enables staking, where you can delegate ADA to pools and earn rewards as they help validate transactions and secure the network.
You can do more with Cardano
On Cardano, you can transfer ADA and other native assets, deploy smart contracts and build decentralised applications across finance, identity and more. As an ADA holder, you can also participate in governance by voting on proposals that shape future upgrades. This broad functionality means buying Cardano lets you interact with a full featured blockchain ecosystem.
