$ADA Cardano ($ADA) is a proof-of-stake (PoS) blockchain platform that aims to provide a secure, scalable, and sustainable infrastructure for decentralized applications (dApps) and smart contracts. It was founded in 2017 and is distinguished by its research-based approach and peer-reviewed development.

Key aspects of Cardano include:

- **Proof of Stake (PoS)**: Allows ADA holders to participate in network governance and validate transactions without the need for energy-intensive mining.

- **Layered architecture**: Separates the settlement layer (for ADA transfers) from the computation layer (for smart contracts), enhancing security and flexibility.

- **Scientific approach**: Its development is based on academic research and peer reviews, ensuring a solid foundation for its evolution.

- **Applications and use cases**: It has been used in digital identity projects, supply chain management, and decentralized financial solutions.
