What is Cardano (ADA)?

Cardano (ADA) is a public blockchain co-founded by Charles Hoskinson and Jeremy Wood and developed through peer-reviewed research. Cardano’s mainnet launched in September 2017 and has been secured by permissionless proof of stake since the Shelley upgrade in July 2020. The Ouroboros protocol validates transactions using staked ADA instead of mining, avoiding the hardware racing that makes proof-of-work networks energy-intensive. ADA is the native token, used for transaction fees, stake-pool delegation, and on-chain governance.

Cardano is maintained by several organizations and built in Haskell for formal verification. Its eUTXO ledger, staking model and on-chain governance shape how ADA is actually used. The sections below cover how the network is built and run, what ADA does day to day, and the risks worth weighing first.

How Cardano is built and governed

• Input Output Global built the core protocol, the Cardano Foundation oversees standards and adoption, and EMURGO supports commercial ventures.
• Intersect, a member-based organization formed in 2023, stewards core development and coordinates the on-chain governance and treasury process.
• Cardano’s core software is written in Haskell, a functional language chosen because it supports formal verification of critical code.
• Early designs proposed separate settlement and computation layers, but on the live network ADA transfers and Plutus smart contracts share a single ledger.

What you can do with ADA

• People use Cardano for staking, decentralized finance, issuing native tokens, and supply-chain applications.
• Cardano tracks funds as unspent transaction outputs (an extended UTXO model), so a transaction’s outcome and fee can be determined before it is submitted.
• ADA holders can delegate coins to a stake pool without giving up custody, and the delegated coins stay spendable in their own wallet.
• A first stake-pool delegation takes a refundable 2 ADA stake-key deposit plus a small fee, returned if you de-register the key.
• On-chain governance lets ADA holders influence protocol changes and treasury spending, usually by delegating voting power to a delegated representative (DRep) or registering as one.

Risks to know before you buy ADA

• Cardano’s research-first development process is deliberate, and features have often arrived later than the community expected.
• Competing smart contract platforms have attracted larger developer ecosystems than Cardano.
• ADA’s price is volatile and can fall sharply, and none of the information on this page is investment advice.
• Staking rewards are variable and never guaranteed, and delegating to a poorly run stake pool can mean smaller returns.
• Transfers cannot be reversed, so never send ADA to a stake address (stake1) or to an address from another blockchain.

How do I buy Cardano (ADA)?

You can buy Cardano on Coinmama with a credit or debit card, a bank transfer over SEPA or SWIFT, Apple Pay, or Google Pay – the options shown at checkout depend on your country. Coinmama has operated since 2013 and does not hold your coins: your ADA is sent to the Cardano wallet address you enter, and support is available 24/7 if anything looks wrong.

Coinmama lists other cryptocurrencies alongside ADA, and each coin page explains what the project actually does. Bitcoin is the original proof-of-work network, and Ethereum is the best-known smart contract platform. Chainlink feeds outside data into smart contracts, and Compound is a lending protocol built on Ethereum. Dogecoin began as an internet joke and is still a meme coin with no supply cap, so read up on any coin before you buy it.
