Cardano (ADA) is a blockchain platform designed to facilitate smart contracts and decentralized applications. Developed by a team led by Charles Hoskinson, one of the co-founders of Ethereum, Cardano aims to address issues faced by earlier platforms, such as scalability, sustainability, and interoperability.At its core, Cardano operates on a proof-of-stake consensus mechanism called Ouroboros. This allows users to validate transactions and create new blocks based on the amount of ADA they hold, rather than relying on energy-intensive processes. This approach is meant to enhance efficiency and reduce environmental impact.Cardano’s development is divided into multiple phases, each focusing on different functionalities. The platform emphasizes a research-driven approach, utilizing peer-reviewed studies to guide its evolution.ADA, the native cryptocurrency of the Cardano network, can be used for various purposes, including staking, transaction fees, and governance. Holders of ADA can participate in decision-making processes regarding upgrades and changes to the platform, contributing to its decentralized nature.
