Cardano
Overview
Cardano is an open-source blockchain platform and cryptocurrency, launched in September 2017. It was developed primarily by IOHK (Input Output Hong Kong), founded by Charles Hoskinson, one of the co-founders of Ethereum. Cardano adopts a rigorous development approach based on academic research and peer review, aiming for security, scalability, and sustainability. Its native token, ADA, serves as the base currency of the Cardano blockchain.

History and Background
Cardano began full-scale development after IOHK was established in 2015. The mainnet was launched in September 2017, and it has since evolved through several stages of a roadmap. The roadmap consists of five main eras: Byron (foundation), Shelley (decentralization), Goguen (smart contracts), Basho (scalability), and Voltaire (governance). Each era introduces specific features and improvements.
Technical Features
Cardano uses the Ouroboros proof-of-stake (PoS) consensus algorithm. Ouroboros is the first academically validated PoS protocol, offering high energy efficiency and strong security. Additionally, Cardano adopts a two-layer architecture: the Cardano Settlement Layer (CSL), which handles payments, and the Cardano Computation Layer (CCL), which executes smart contracts and applications. This separation provides flexibility and ease of upgrades.
Smart Contracts and Decentralized Applications
In September 2021, smart contract functionality was introduced through the Alonzo hard fork, an upgrade of the Goguen era. Cardano uses a smart contract language called Plutus, which is based on Haskell and emphasizes safety and correctness. Additionally, Marlowe is a domain-specific language (DSL) for financial contracts, enabling non-developers to write smart contracts. Various decentralized applications (DApps) and DeFi (decentralized finance) projects are currently being developed on Cardano.
Governance and Sustainability
The Voltaire era aims to introduce Cardano's decentralized governance system. ADA holders can vote on network upgrades and fund allocation. Additionally, Cardano funds network development through a Treasury system, ensuring long-term sustainability.
Ecosystem and Partnerships
Cardano is building real-world use cases, particularly in Africa, such as providing blockchain solutions in education and agriculture in Ethiopia. Numerous DeFi projects, NFT marketplaces, and games are also active within the Cardano ecosystem. Key partnerships include a digital identity system project with the Ethiopian government and research collaborations with several universities.
Latest Trends
Throughout 2024 and 2025, Cardano has achieved significant developments. In 2024, Hydra, a major upgrade of the Basho era, matured further, greatly enhancing network scalability. Hydra is a layer-2 scaling solution with the potential to process millions of transactions per second. Additionally, at the end of 2024, an on-chain governance system based on CIP-1694 (Cardano Improvement Proposal), the first phase of the Voltaire era, was introduced, allowing ADA holders to directly participate in network decision-making. In early 2025, the Mithril protocol was updated, increasing synchronization speed and security for light clients. Furthermore, the Cardano ecosystem has seen an increase in total value locked (TVL) in the DeFi sector, with several new DApps being launched. Notably, the digital identity system project in Ethiopia has expanded to cover over 5 million students. On the regulatory front, Cardano has remained relatively free from legal issues with the U.S. Securities and Exchange Commission (SEC), which serves as a positive signal for investors. However, stricter cryptocurrency regulations in some countries could affect Cardano's global adoption.
