What is Cardano?

Cardano is a prominent blockchain platform that has established itself as a significant player in the cryptocurrency ecosystem since its launch in 2017. This article provides a comprehensive overview of Cardano, its underlying technology, unique features, and the native ADA cryptocurrency, while exploring its relationship to Ethereum and what distinguishes it in the blockchain space.

What is Cardano?

Cardano is a decentralized cryptocurrency network designed to offer users a faster and more scalable alternative to the Ethereum protocol. Understanding what is Ethereum Cardano requires recognizing that while Ethereum pioneered smart contract functionality, Cardano was built to address Ethereum's limitations through a more scientific approach. The platform enables third-party developers to create decentralized applications (dApps) across various sectors, including decentralized finance (DeFi), play-to-earn gaming, and non-fungible token (NFT) marketplaces. Often categorized as an "Ethereum competitor," Cardano shares this classification with other blockchain platforms such as Solana, Avalanche, and Polkadot.

The blockchain was founded by Charles Hoskinson and Jeremy Wood, both of whom were previously lead developers on the Ethereum blockchain. In 2015, they departed from the Ethereum team to address critical scalability challenges, particularly slow transaction speeds and high network fees. Prior to its public launch, Cardano raised over $62 million through premarket sales of its ADA coin. The platform's ongoing development is managed by software companies Input-Output Hong Kong (IOHK) and Emurgo, while the nonprofit Cardano Foundation handles funding organization.

How Does Cardano Work?

Cardano operates using a distinctive proof-of-stake (PoS) consensus mechanism called "Ouroboros" to verify cryptocurrency transactions on its network. This differs from Ethereum's original proof-of-work model, though Ethereum has since transitioned to proof-of-stake as well. In this system, computers (nodes) on the Cardano blockchain lock the native ADA cryptocurrency to gain opportunities to confirm and record crypto transfers on a public payment ledger. The platform utilizes Verifiable Random Functions (VRFs) to assign different validators for each data block, with nodes staking higher amounts of ADA having better odds of posting multiple transactions and receiving crypto rewards.

A unique feature of Cardano's PoS system is its organization of transaction data into two distinct time sets: epochs and slots. In the Ouroboros model, an "epoch" represents five days of transaction data grouped into one-second "slots." The Cardano Foundation estimates that the blockchain's algorithm assigns a new "slot leader" approximately every 20 seconds to post ADA transfers. This flexible epoch/slot model allows Cardano to process an average of 250 transactions per second (TPS), naturally adjusting for network demand and contributing to its scalability, fast confirmation times, and low transaction fees.

Beyond its PoS design, Cardano provides developers with access to smart contracts—blockchain-based protocols that execute commands based on precoded instructions. Similar to Ethereum's smart contract functionality, when someone initiates a crypto transfer on a Cardano-based decentralized platform like SundaeSwap, the smart contract automatically recognizes the transaction data and sends the requested cryptocurrency to the user's wallet. These smart contracts enable dApps on the Cardano blockchain to offer secure peer-to-peer features without relying on centralized entities such as banks or governments.

What Makes Cardano Special?

When comparing what is Ethereum Cardano, Cardano distinguishes itself through its deliberately systematic and scientific approach to blockchain development. The development team commits to conducting multiple trials and publishing peer-reviewed research papers for community review before implementing any new changes. This rigorous methodology has earned Cardano recognition as one of the most "scientific" cryptocurrency projects in the industry. Several prestigious academic institutions, including the University of Edinburgh and the University of Zurich, collaborate closely with the Cardano Foundation, IOHK, and Emurgo on software upgrades. While this emphasis on scientific rigor may slow development progress compared to Ethereum's faster iteration approach, it significantly enhances Cardano's reputation as a credible cryptocurrency project and minimizes the risk of bugs or unforeseen errors.

Another distinctive feature of Cardano is its dual-blockchain system, divided between the Settlement Layer and Computation Layer. The Cardano Settlement Layer serves as the main PoS network that verifies and records ADA transfers on the blockchain, while the Computation Layer enables developers to build dApps with smart contracts on Cardano's Plutus Platform. This separation aims to optimize the core blockchain's security and efficiency while providing programmers with greater flexibility for building decentralized projects—a different architectural approach from Ethereum's single-layer design.

What is the ADA Coin?

ADA, named after pioneering computer scientist Ada Lovelace, is Cardano's native cryptocurrency. Validator nodes lock ADA in "stake pools" on the blockchain to secure the protocol and broadcast new transaction data on Cardano's payment ledger. The probability of a stake pool being selected by Cardano's algorithm to confirm transactions and receive crypto rewards increases with the amount of ADA locked in it. Additionally, validators can use their ADA as "votes" on proposed upgrades from the developer community through on-chain governance proposals.

Cardano charges network fees (also known as gas fees) for every transaction on its blockchain to compensate the ADA staking community. These fees are distributed either to stake pools or Cardano's Treasury. While gas fees fluctuate based on network demand and protocol changes, the average transaction cost typically remains below $0.50, generally lower than Ethereum's gas fees.

Beyond staking and governance, ADA serves multiple purposes within the ecosystem. Users utilize ADA to access services on Cardano-based dApps, such as decentralized trading platforms, and to purchase digital collectibles like Cardano NFTs. Due to Cardano's popularity, ADA has also become an actively traded crypto asset on various cryptocurrency exchanges.

Where to Buy Cardano's ADA Coin

ADA is widely available across numerous cryptocurrency trading platforms. Major centralized exchanges such as Coinbase and Gemini offer ADA trading services, and even some stock trading platforms like Robinhood provide access to ADA coins. To find a comprehensive list of platforms selling ADA, traders can visit crypto price aggregator websites such as CoinMarketCap or CoinGecko and search for "Cardano." On the aggregator's Cardano price page, clicking the "Markets" tab reveals all trading platforms currently selling the ADA cryptocurrency, allowing users to compare options and choose the most suitable platform for their needs.

How to Stake Cardano

For ADA holders interested in earning passive income, Cardano offers the option to "delegate" ADA to a stake pool in exchange for a percentage of the node's crypto rewards. The staking process begins with downloading a Cardano-compatible wallet such as Daedalus Wallet, Nami, or Yoroi. After setting up the wallet, users must transfer ADA into their new account using the wallet's public blockchain address.

For example, transferring ADA from a centralized exchange to a Nami wallet involves the following steps: logging into the exchange account, selecting "Cardano," clicking "Withdraw," entering the amount of ADA to send, copying the ADA public address from the Nami wallet, pasting this address on the exchange platform, and finally confirming the transfer.

Most Cardano-specific wallets feature dedicated staking portals where users can browse and select from various stake pools. It is important to review each stake pool's reputation and minimum ADA requirements before delegating funds. Once the ADA transfer to a stake pool is confirmed, users can monitor their ADA rewards through the wallet's staking dashboard, providing transparent visibility into their passive income generation.
