What Is Cardano (ADA)? Blockchain Overview

Cardano is a third-generation proof-of-stake blockchain platform designed to run smart contracts and decentralized applications (dApps). Founded by Charles Hoskinson — a co-founder of Ethereum — Cardano was launched in 2017 and is developed by IOHK (Input Output Hong Kong) under a research-first methodology.

The platform's native cryptocurrency, ADA, is named after 19th-century mathematician Ada Lovelace, widely regarded as the world's first computer programmer. ADA is used to pay transaction fees, participate in network governance, and earn staking rewards through the Ouroboros proof-of-stake consensus mechanism.

Cardano uses a unique two-layer architecture: the Cardano Settlement Layer (CSL) handles ADA transfers, while the Cardano Computation Layer (CCL) runs smart contracts. This separation allows each layer to be optimized independently, improving scalability and security compared to single-layer blockchains.

The blockchain stands out for its peer-reviewed academic approach — every major protocol update goes through rigorous scientific review before implementation. This process, while slower than competitors, has produced a platform with strong security guarantees and a resilient developer community. Cardano currently supports over 1.3 million staking wallets and has processed more than 110 million transactions.
