Cardano
Overview
Cardano (카르다노) is an open-source blockchain platform that uses a Proof-of-Stake (PoS) consensus mechanism. It was launched in September 2017 and uses the cryptocurrency ADA as its native token. Cardano is characterized by its development based on academic research and peer review, with scalability, interoperability, and sustainability as its core goals. The platform is primarily developed by IOHK (Input Output Hong Kong), founded by Charles Hoskinson, one of the co-founders of Ethereum.

History and Background
The Cardano project began in 2015 and its mainnet was launched in 2017. Charles Hoskinson participated in the early development of Ethereum but opposed its commercial approach, leading him to establish Cardano to create a blockchain with an academic and scientific approach. The project is operated through the collaboration of three organizations: IOHK, the Cardano Foundation, and Emurgo.
Technical Features
Cardano has a two-layer architecture. The first layer is the Cardano Settlement Layer (CSL), which handles payments and transactions, and the second layer is the Cardano Computation Layer (CCL), which executes smart contracts and applications. This separation enhances flexibility and security.
As its consensus algorithm, Cardano uses a proof-of-stake method called Ouroboros (오우로보스). Ouroboros is the first PoS protocol designed based on a peer-reviewed academic paper, offering high energy efficiency and strong security. Cardano is also developed using the Haskell programming language, boasting high reliability and accuracy.
Development Phases
Cardano's development is divided into several eras: Byron (foundation), Shelley (decentralization), Goguen (smart contracts), Basho (scalability), and Voltaire (governance). Currently, the Goguen and Basho eras are underway, with improvements in smart contract functionality and scalability.
Ecosystem and Applications
Cardano is used in various fields, notably in Africa for digital identity systems, agricultural supply chain management, and educational credentialing. Additionally, decentralized finance (DeFi) applications and non-fungible token (NFT) marketplaces are actively being developed. Cardano's native token, ADA, is used for paying transaction fees, staking, and participating in governance.
Latest Trends
As of 2024 and 2025, Cardano is undergoing significant updates and changes. In September 2024, Cardano introduced its first on-chain governance system through the 'Chang' hard fork. This marks an important milestone signaling the start of the Voltaire era, allowing ADA holders to directly participate in network decision-making. Additionally, a new consensus protocol called 'Ouroboros Leios' is expected to be introduced in 2025, which is anticipated to significantly improve throughput.
Furthermore, Cardano's DeFi ecosystem has grown rapidly in recent years. As of the end of 2024, the total value locked (TVL) in Cardano-based DeFi protocols exceeded $500 million, with various stablecoins and lending protocols emerging. The NFT market has also become active, with Cardano building the third-largest NFT ecosystem after Ethereum and Solana.
Meanwhile, Cardano is actively responding to changes in the regulatory environment. In 2024, the U.S. Securities and Exchange Commission (SEC) moved to classify some cryptocurrencies as securities, but Cardano emphasizes its academic approach and transparency, continuing efforts to ensure regulatory compliance. Additionally, it is strengthening partnerships with local governments and institutions to expand adoption in emerging markets such as Africa and Southeast Asia.
