Cardano (ADA)

Cardano is a third-generation blockchain founded by Charles Hoskinson. It was developed by IOG, the Cardano Foundation, and Emurgo with a strong focus on scalability, security, and sustainability. Unlike Bitcoin and Ethereum, Cardano uses Ouroboros, a Proof-of-Stake (PoS) system that is more energy-efficient and designed for long-term growth. 

What makes Cardano unique is its scientific approach, with peer-reviewed research backing its development. It supports smart contracts (Plutus), aims for full decentralization, and is working toward community-driven governance through the Voltaire era. Its layered architecture enhances scalability and interoperability, making it a strong contender in the blockchain space.
