Cardano (ADA) stands as a third-generation blockchain platform designed to address limitations observed in earlier networks like Ethereum and Bitcoin. It takes its name from Gerolamo Cardano, a renowned 16th-century Italian polymath. The project positions itself as a next-generation blockchain, integrating advanced technologies to create a more sustainable and secure cryptocurrency ecosystem.
Similar to other Layer 1 blockchain projects, Cardano operates using a native token known as ADA. This token honors Ada Lovelace, a 19th-century mathematician recognized as the world's first computer programmer. ADA serves a dual purpose: it functions as both a settlement currency and a core component of the platform's consensus mechanism.
How Does Cardano Work?
Cardano distinguishes itself by being one of the first major blockchains developed using the Haskell programming language, prized for its high assurance and security features. Its architecture employs a multi-layered protocol that handles complex operations efficiently. This structure consists of the Cardano Settlement Layer (CSL), which manages balances and acts as a unit of account, and the Cardano Computation Layer (CCL), which facilitates smart contracts, identity recognition, and compliance.
At the heart of Cardano’s operation is Ouroboros, an energy-efficient Proof-of-Stake (PoS) consensus mechanism. In this system, users participate in network validation by staking their ADA holdings. Validators are then rewarded with additional ADA in proportion to their staked amount. This in-house developed technology allows Cardano to consume only a fraction of the energy required by Proof-of-Work blockchains like Bitcoin and early versions of Ethereum.
Beyond its environmental benefits, Cardano effectively tackles scalability challenges that have hindered older blockchain networks—all while maintaining a strong commitment to decentralization. Currently, Cardano can process up to 250 transactions per second (TPS), a significant improvement over Ethereum's 15 TPS and Bitcoin's 4 TPS. This capacity supports the development and launch of decentralized applications (DApps), contributing to Cardano’s growing popularity.
ADA tokens are used to pay transaction fees and can be staked to earn yields denominated in ADA. Future plans include enabling ADA holders to participate in on-chain governance, giving them a direct voice in the evolution and policy decisions of the blockchain network.
Major Network Upgrades
The Alonzo Upgrade
The Alonzo upgrade, implemented in September 2021, was a milestone update that introduced smart contract functionality to the Cardano mainnet. This enhancement positioned Cardano as a direct competitor to Ethereum in the decentralized application space. With smart contracts, developers gained the ability to build a wide variety of DApps and even mint non-fungible tokens (NFTs), significantly expanding Cardano's utility in the decentralized finance (DeFi) ecosystem.
The Vasil Upgrade
Named in honor of Vasil Dabov, a late Bulgarian mathematician and Cardano contributor, the Vasil upgrade was launched in September 2022. This update brought substantial improvements to Cardano’s programming language, Plutus, enabling developers to create DApps with higher speed, better transactional capability, and more powerful scripts.
A key innovation introduced in the Vasil upgrade was diffusion pipelining, which optimized the way new blocks are shared across the network. This ensured that blocks could be propagated to participants within five seconds of creation, enhancing overall network throughput and user experience. The upgrade was executed via a hard fork and was strategically timed shortly after Ethereum’s own transition to a Proof-of-Stake consensus model.
ADA Tokenomics and Supply
ADA has a maximum supply capped at 45 billion tokens. As of September 2022, approximately 34.18 billion ADA were in circulation. The initial distribution occurred through an Initial Coin Offering (ICO) that raised around $79.2 million across five rounds of public sales, distributing 25.9 billion ADA.
An additional 5.18 billion ADA (20% of the initial supply) was allocated to the three entities overseeing Cardano’s development: Input Output Hong Kong (IOHK), the Cardano Foundation, and Emurgo. IOHK received 2.46 billion tokens, Emurgo received 2.07 billion, and the Cardano Foundation was allocated 640 million ADA.
At launch, 31.11 billion ADA were in circulation. The remaining 13.88 billion were reserved to incentivize stakers and support network security. New ADA tokens are periodically issued and distributed as staking rewards, a process that will continue until the maximum supply of 45 billion is reached. It is estimated that around 2.9 billion ADA had been distributed via staking rewards as of late 2022.
The Founders and Development Background
Cardano was officially launched in 2017 by Charles Hoskinson, who began research and development on the project in 2015. Hoskinson is a notable figure in the blockchain space, having been a co-founder of Ethereum. He departed from Ethereum due to strategic disagreements—specifically, Hoskinson favored a for-profit model with venture capital involvement, while Vitalik Buterin advocated for a non-profit approach.
Soon after leaving Ethereum, Hoskinson partnered with former colleague Jeremy Wood to establish Input Output Hong Kong (IOHK) in 2015. IOHK is an engineering firm dedicated to the development of Cardano, while also providing blockchain solutions for academic, governmental, and corporate clients. Hoskinson’s background also includes serving as the founding chairman of the Bitcoin Foundation's education committee and establishing the Cryptocurrency Research Group in 2013.
What Makes Cardano Unique?
Cardano’s development approach sets it apart from many other blockchain projects. It is built on an open-source, peer-reviewed model where every component of its infrastructure undergoes rigorous academic scrutiny using evidence-based methods. This process involves researchers and experts from around the world, ensuring that upgrades are both scientifically sound and secure.
While this methodical approach has sometimes resulted in longer development cycles, it reinforces the network’s reliability and long-term viability. Each upgrade is thoroughly tested and validated before implementation, reducing the risk of vulnerabilities and fostering trust within the community.

Frequently Asked Questions
What is the main purpose of Cardano?
Cardano aims to provide a more scalable, sustainable, and secure blockchain platform compared to earlier generations. It supports smart contracts, decentralized applications, and a robust staking mechanism, all while emphasizing peer-reviewed research and formal verification.
How is Cardano different from Ethereum?
While both support smart contracts and DApps, Cardano uses a Proof-of-Stake consensus mechanism from the outset, making it more energy-efficient. It also adopts a research-driven, academically peer-reviewed development approach, which contrasts with Ethereum’s more iterative development process.
Can I earn rewards with Cardano?
Yes, you can earn rewards by staking your ADA tokens in the network. Stakers contribute to network security and, in return, receive additional ADA as rewards distributed through the protocol’s incentive system.
What was the significance of the Vasil upgrade?
The Vasil upgrade enhanced Cardano’s scripting capabilities, improved transaction throughput, and introduced diffusion pipelining for faster block propagation. These improvements significantly boosted the network’s performance and developer experience.
Is Cardano decentralized?
Yes, Cardano is designed as a decentralized network. Its Proof-of-Stake consensus mechanism allows anyone to participate as a validator by staking ADA, and governance mechanisms are being developed to further decentralize decision-making.
Where can I learn more about staking ADA?
Staking ADA involves delegating your tokens to a stake pool or running your own pool. Detailed guides and community resources are available through official Cardano forums and educational platforms. To 👉 view real-time tools for tracking staking rewards and network metrics, many platforms offer updated analytics.
