How does staking ADA work?

Cardano uses a Proof-of-Stake (PoS) mechanism called Ouroboros, which allows ADA holders to delegate their tokens to a staking pool. This helps secure the network while earning passive staking rewards. You don’t need to lock or transfer your ADA because it stays in your wallet and remains fully liquid while being staked.

Is Cardano environmentally friendly?

Cardano’s PoS model is highly energy-efficient compared to Bitcoin’s Proof-of-Work (PoW). It doesn't require energy-intensive mining, making it one of the more sustainable blockchains. This design aligns with Cardano’s mission of building responsible and scalable technology for global adoption.

Does Cardano support smart contracts?

Yes, Cardano added smart contract functionality with the Alonzo upgrade in 2021. Developers can now build decentralized apps using Plutus, Cardano’s smart contract programming language. This has enabled the rise of DeFi, NFT, and gaming platforms within the Cardano ecosystem.

How many ADA tokens are there?

Cardano has a maximum supply of 45 billion ADA. As of 2025, over 35 billion tokens are already in circulation. New ADA enters the ecosystem through staking rewards and treasury funding for development and innovation.
