What Is Cardano? The Research-Driven Blockchain Explained
Cardano is a public blockchain platform known for building its protocol through academic research and peer review rather than moving fast and iterating in the open. It was co-founded by Charles Hoskinson, who had previously co-founded ethereum, and the project launched in 2017. Cardano’s native token, ADA, is used to pay transaction fees, secure the network through staking, and participate in on-chain governance.
How cardano works
Cardano is a proof-of-stake blockchain, meaning the network is secured by participants who lock up ADA rather than by miners burning electricity to solve computational puzzles. Its consensus mechanism, called Ouroboros, was developed with input from academic cryptography research and selects validators to create new blocks based on the amount of ADA staked behind them. For a broader explanation of how blockchains reach agreement on transaction history, see our blockchain guide. Smart contracts, the self-executing code that lets developers build applications on top of a blockchain, were not part of Cardano at launch. They arrived later through a platform called Plutus, introduced in an upgrade known as Alonzo, which extended the network beyond simple value transfers into programmable applications.

The research-first philosophy
What sets Cardano apart from most other blockchain projects is the way it approaches development. Rather than shipping features quickly and patching problems afterward, the team behind Cardano has leaned on academic research and formal methods, a mathematically rigorous way of specifying and verifying software before it is deployed. Papers describing core parts of the protocol have gone through peer review, the same process used in academic journals, before being implemented in code. This is the defining characteristic of Cardano as a project: proponents argue that the slower, evidence-based pace produces a more secure and predictable foundation, while critics say it has meant slower delivery of features that rival networks such as ethereum and solana rolled out much sooner.
The staged roadmap approach
Cardano’s development has historically been organized into a series of named eras, each associated with a broad set of capabilities rather than a single feature. Early phases focused on getting the base network and its currency running securely, later phases introduced decentralization of block production away from the founding entities, and subsequent phases layered in smart contracts, scaling improvements, and on-chain governance tools that let ADA holders vote on the network’s future direction. This staged, roadmap-driven structure is one of the things Cardano is best known for in the wider crypto industry, and it reflects the same research-first mindset: each stage is meant to be thoroughly tested before the next one builds on top of it.
What cardano is used for
- Staking ADA to help secure the network and earn rewards, without giving up custody of the underlying coins.
- Building and using smart contracts and decentralized applications through the Plutus platform.
- Participating in on-chain governance, where ADA holders can vote on proposed changes to the protocol.
- Piloting real-world use cases, including partnerships explored in areas like education, supply chain tracking, and identity credentials in various countries.
Staking on cardano
One of Cardano’s most accessible features is its approach to staking, the process of putting coins to work securing a proof-of-stake network in exchange for rewards. ADA holders can delegate their coins to a stake pool, an operator that runs the validating infrastructure, without transferring ownership or locking the funds away. Delegators keep control of their ADA the entire time and can move or spend it whenever they choose, which makes staking on Cardano notably non-custodial compared with systems that require funds to be locked for a fixed period. Our crypto staking guide covers how staking works across different networks in more detail.
Risks to understand
Cardano’s methodical, research-driven pace is also its most common criticism. Features that competing blockchains rolled out quickly have sometimes taken Cardano longer to deliver, and some developers and investors see that as a competitive disadvantage in a fast-moving industry. Its smart contract ecosystem, while growing, remains smaller than ethereum’s in terms of the number of applications, developers, and total value used within it. Measures of real-world adoption and on-chain activity are also debated, with supporters and skeptics often reading the same usage data differently. As with any cryptocurrency, ADA’s price can move sharply in either direction, and regulatory treatment of tokens used for staking and governance continues to evolve; our crypto regulation overview tracks how that landscape is shifting.
How to get ADA
ADA can be bought on major cryptocurrency exchanges alongside other large-cap coins. Our how to buy crypto guide walks through the general process, including comparing platforms such as those covered in our Binance review and Coinbase review. Once purchased, many holders move ADA into a wallet they control before delegating it to a stake pool, which keeps the coins in their own custody rather than leaving them on an exchange.
Frequently asked questions
What is Cardano used for? Cardano is used for staking, running smart contracts and decentralized applications, and participating in on-chain governance votes on ADA holders’ proposed changes to the network.
Who created Cardano? Cardano was co-founded by Charles Hoskinson, who also co-founded ethereum before starting Cardano with a focus on peer-reviewed research and formal methods.
Is Cardano proof of work or proof of stake? Cardano uses proof of stake through its Ouroboros protocol, meaning validators are chosen based on staked ADA rather than computational mining.
Can I stake ADA without locking it up? Yes. Delegating ADA to a stake pool does not require transferring ownership or locking the coins, so holders retain control and can move their funds at any time.
How is Cardano different from ethereum? Both were shaped by Charles Hoskinson, but they took different paths. Ethereum launched with smart contracts from the start and iterated quickly in the open, while Cardano added smart contracts later after building its base layer through peer-reviewed research.
Does Cardano have smart contracts? Yes. Smart contract functionality was added through the Plutus platform in the Alonzo upgrade, letting developers build decentralized applications on the network.
