What is Cardano? 
Cardano is a decentralised public blockchain and cryptocurrency project and is fully open source. Cardano is developing a smart contract platform which seeks to deliver more advanced features than any protocol previously developed. It is the first blockchain platform to evolve out of a scientific philosophy and a research-first driven approach. The development team consists of a large global collective of expert engineers and researchers.
Staking
Staking is used to validate transactions on the blockchain network. The pools with the most stake get the privilege of verifying new transactions. Coin holders who stake are rewarded with a small share of the rewards. Everybody wins. You can remove your stake at any time and it costs you nothing but a few click.
