How many Cardano coins are there?

The maximum supply is 45 billion ADA, and most of it is already in circulation. New ADA is released from a reserve as staking rewards, and that release slows over time.

How does Cardano staking work?

You delegate ADA to a stake pool from a wallet that supports Cardano staking. Your ADA stays in your wallet and is never locked, so you can move or spend it at any time. Rewards are paid every epoch, which lasts five days, and have typically worked out at low single-digit percentages a year.

Can you mine Cardano?

No. Cardano uses proof of stake, not proof of work, so there is no mining. Stake pool operators produce blocks instead, and ADA holders take part by delegating to them.

How fast is Cardano, and how much do transactions cost?

A new block is added about every 20 seconds. Fees depend on the size of the transaction, and a simple transfer usually costs a fraction of one ADA.

How is Cardano governed?

Since the Chang upgrade in 2024 and the Plomin upgrade in early 2025, Cardano has had full on-chain governance. ADA holders vote directly or through delegated representatives (DReps) on protocol changes and on how the network's treasury is spent, guided by a constitution adopted in 2025.

How is Cardano different from Ethereum?

Both are proof-of-stake smart contract platforms. Cardano puts peer-reviewed research and formal methods first and writes its smart contracts in languages based on Haskell, while Ethereum uses Solidity and has a much larger developer community, more apps and more value locked in DeFi.

No. The network produces blocks around the clock, it completed major upgrades in 2024 and 2025, and work continues on scaling projects such as Hydra and Leios. Its price has fallen well below its 2021 peak, though, and its DeFi ecosystem remains much smaller than those of Ethereum or Solana.

Is Cardano a good investment?

We can't tell you whether ADA is right for you. Cardano has an active community and a research-led approach, but its price is highly volatile, its app ecosystem is smaller than its main rivals' and future growth is uncertain. Only invest what you can afford to lose, and consider speaking to a licensed financial adviser.

Q: What is ADA used for?

ADA pays transaction fees on Cardano, is staked to secure the network and earn rewards, and gives holders a vote in the network's on-chain governance. It is also used for trading and as collateral in Cardano's DeFi apps.
