$ADA
**Cardano (ADA)** is a third-generation blockchain platform founded by Charles Hoskinson, co-founder of Ethereum. It aims to solve scalability, interoperability, and sustainability issues faced by earlier blockchains like Bitcoin and Ethereum. Cardano uses a unique **proof-of-stake (PoS)** consensus mechanism called **Ouroboros**, which is energy-efficient and secure.
The platform is built on peer-reviewed research and emphasizes academic rigor. Its native cryptocurrency, **ADA**, is used for transactions, staking, and governance. Cardano’s development occurs in phases: **Byron (foundation), Shelley (decentralization), Goguen (smart contracts), Basho (scaling), and Voltaire (governance)**.
Cardano focuses on **DeFi, NFTs, and identity solutions**, particularly in emerging markets. Its scalability solutions include **Hydra**, a layer-2 protocol. ADA ranks among the top cryptocurrencies by market cap, appealing to long-term investors due to its scientific approach and sustainability.
