Why Cardano? What Makes Cardano the Best Blockchain of Choice?


Cardano is an open-source blockchain project that was launched in 2017 to address the challenges of existing blockchains and develop a more balanced and sustainable ecosystem that better meets the needs of its users.

The Evolution of Blockchain Technology

Blockchain technology has evolved from the first generation (e.g., Bitcoin) that provided secure cryptocurrency transfer to the second generation (e.g., Ethereum) that offered enhanced solutions for smart contract execution and application development. However, second-generation blockchains often face issues in scalability.

Cardano: A Third-Generation Blockchain

Cardano is considered a third-generation blockchain that combines the features of previous generations while evolving to meet the changing needs of users. To ensure the highest security, scalability, and functionality, Cardano focuses on three core concepts: scalability, interoperability, and sustainability.


Scalability is crucial in ensuring that the Cardano network can process an increasing number of transactions as user demand grows. It provides higher bandwidth capabilities, allowing transactions to carry a significant amount of supportive data that can be easily managed within the network. Cardano uses various techniques such as data compression and is working to introduce Hydra, which will enable multiple side-chain functionality.


Interoperability ensures a multi-functional environment for financial, business, or commercial operations by enabling users to interact with multiple currencies across various blockchains. Cardano is being developed to support cross-chain transfers, multiple token types, and commonly used smart contract languages.


Sustainability is essential to ensure that the system is self-sustainable. To drive growth and maturity in a truly decentralized manner, Cardano is built to allow the community to maintain its continuous development by participating, proposing, and implementing system improvements. The treasury system is controlled by the community and is refilled constantly from potential sources such as newly-minted coins being held back as funding, a percentage of stake pool rewards, and transaction fees.

Advantages of Cardano

Cardano offers several advantages over other blockchain projects. It uses formal methods, such as mathematical specifications, property-based tests, and proofs, to achieve strong guarantees on the functional correctness of core components of the system. Cardano is written in Haskell, a secure functional programming language, and employs powerful methods for ensuring correctness of the code. The Ouroboros protocol establishes rigorous security guarantees and was delivered with several peer-reviewed papers presented in top-tier cybersecurity and cryptography conferences.

Cardano is energy-efficient as it is a proof-of-stake blockchain. In contrast to proof-of-work blockchains, Cardano requires much less energy and computational power, making it a more sustainable solution. Cardano also handles upgrades differently than traditional blockchains, using a hard-fork combinator technology that ensures a smooth transition to a new protocol without erasing the previous history.

Decentralization is also a fundamental feature of Cardano. It is maintained by almost 3,000 distributed stake pools that are operated by the community. All blocks and transactions are validated by network participants without any reliance on a centralized authority.

Finally, Cardano offers a functional environment for business use cases, providing a foundation for global decentralized finance to develop a range of DApps that can run using functional and domain-specific smart contracts, providing multi-asset tokens for any needs.

Staking in Cardano

Staking is a critical component of Proof of Stake (PoS) protocols, which allows users to earn rewards by holding and maintaining a certain amount of cryptocurrency in their wallets. In PoS, the concept of staking refers to the process of locking a certain amount of cryptocurrency as collateral to become eligible to participate in the consensus process and validate transactions. In return, stakers earn rewards proportional to their stake, providing an incentive toto maintain the network and discourage malicious behavior. The amount of reward a staker can earn depends on various factors, including the size of their stake, the length of time they've been staking, and the overall network participation rate.

In addition to earning rewards, staking offers several benefits to network participants. For one, stakers can help to increase the security and stability of the network by providing a more decentralized and distributed infrastructure. By participating in the consensus process, stakers have a direct say in the governance and decision-making of the network, making it more democratic and transparent. Furthermore, staking offers a more energy-efficient alternative to PoW protocols, as it eliminates the need for resource-intensive mining operations.


Cardano has emerged as one of the best blockchain projects due to its focus on scalability, interoperability, and sustainability. It offers several advantages over other blockchain projects, including energy efficiency, decentralization, and formal methods for ensuring correctness.

Cardano's Proof of Stake protocol provides stakers with the ability to earn rewards while maintaining the network and making it more secure and stable. With its emphasis on functional smart contracts and multi-asset tokens, Cardano is well-positioned to support a wide range of decentralized finance applications. The unique features of Cardano make it a strong contender in the evolving landscape of blockchain technology.
