What is Cardano (ADA) and how does it work?

Cardano, a standout among over 10,000 cryptocurrencies, is renowned for its innovative approach in the crypto market. It was conceived by Charles Hoskinson, a co-founder of Ethereum, and operates on a decentralized public ledger that utilizes blockchain technology to meticulously record and organize every transaction.

Established in 2015 by Hoskinson, the Cardano ecosystem diverges from typical crypto narratives like Bitcoin's. It was not predefined by a white paper but instead evolved through a vision of addressing existing problems in crypto ecosystems. This vision led to the creation of three foundational entities: the Cardano Foundation, Input Output (IOHK), and Emurgo, focusing on a blockchain built on a non-custodial, delegated proof-of-stake protocol.

Cardano's native token, ADA, serves multiple purposes. It acts as a digital currency for storing value and facilitating quick, low-cost fund transfers, making it highly applicable in business and finance. The Cardano blockchain, distinct for its foundation in scientific and mathematical principles, supports smart contracts and the development of decentralized applications and protocols.

Uniquely, Cardano emphasizes compliance with global regulations, aiming to offer financial services inclusively. It addresses key blockchain industry challenges, such as utilizing mathematics for enhanced security, separating accounting and computational layers, creating a secure voting mechanism for token holders, and achieving a scalable consensus mechanism.

What does Cardano do?

Cardano stands out as a multifaceted blockchain platform, offering a range of features that extend beyond conventional cryptocurrency functions. At its core, Cardano provides a means for currency exchange through its cryptocurrency wallet, allowing users to send, receive, and trade Cardano (ADA) for goods and services. This functionality is just the tip of the iceberg.

A significant aspect of Cardano's offering is its capability for executing smart contracts. These contracts are self-executing agreements that are automatically fulfilled when predetermined conditions are met, streamlining the process of contractual obligations. In addition to this, Cardano is a key player in the decentralized finance (DeFi) sphere. It enables users to bypass traditional financial intermediaries like banks, facilitating direct and permission-less transactions between parties. This opens up a wide range of financial services within the digital space, including lending, trading, asset management, and insurance, all underpinned by the Cardano blockchain.

The technical architecture of Cardano is what sets it apart as a third-generation blockchain platform. It employs an extended unspent transaction output (UTXO) model, which is a blend of Bitcoin's transaction-based design and Ethereum’s accounting model, offering a more versatile framework. The Cardano blockchain comprises four integral layers, each contributing to its robustness and efficiency:

  • The Settlement Layer: This foundational layer underpins the blockchain's entities and governance structure, serving as a base for all other components.
  • The Consensus Layer: Utilizing the Ouroboros family of proof-of-stake (PoS) consensus protocols, this layer enhances security akin to proof-of-work systems but at a significantly reduced energy cost.
  • The Networking Layer: A sophisticated peer-to-peer networking stack provides essential infrastructure for protocol support, including features like pipelining, multiplexing, and safeguards against harmful actors.
  • The Scripting Layer (Plutus): This layer introduces smart contract functionalities to the network through its scripting language.

In summary, Cardano is more than just a digital currency; it is a comprehensive blockchain ecosystem offering advanced financial services, underpinned by a sophisticated, layered architectural model that enhances transaction security, efficiency, and flexibility.

The Role of ADA in Cardano

ADA, the native token of the Cardano blockchain, plays a pivotal role in both the network's functionality and its broader ecosystem. As the in-house token residing on the Cardano Settlement Layer, ADA's total supply is capped at 45 billion tokens, to be gradually released through a process called minting. This hard limit ensures ADA's deflationary nature over time, although the ecosystem anticipates an inflationary trend until a significant portion of the reserves is circulated, expected to start around 2030.

ADA is not just a currency; it's an integral part of Cardano's operational framework. It facilitates governance, spurs network participation, and enhances security through increased user involvement. Beyond trading, ADA is instrumental in creating tokens, decentralized applications (dApps), and smart contracts, thereby fostering ecosystem growth and enabling a wide range of financial exchanges and services.

A key feature of ADA within Cardano is staking, which offers benefits for long-term holders. By staking ADA, users contribute to network security, support decentralized applications, and may even influence the development of local government services on the Cardano blockchain. This process of staking not only secures the network but also allows ADA holders to earn rewards, thereby incentivizing participation and investment in the ecosystem.

Regarding tokenomics, ADA has a current circulating supply of approximately 35 billion out of the 45 billion cap. Projects built on the Cardano blockchain may receive federal support, reflecting their societal contributions. Additionally, state and local governments could leverage ADA's annual inflation rate, currently estimated at 1.55%, to develop secure and transparent solutions for public services.

On the user side, ADA can be exchanged for fiat currencies and stored in various wallets, including Cardano's native offerings like Daedalus and Yoroi, as well as third-party services. The token is designed for secure value exchange and operates on Ouroboros, a proof-of-stake consensus protocol. Moreover, the Cardano blockchain supports hosting other cryptocurrencies, NFTs, smart contracts, and dApps.

ADA's use cases extend to peer-to-peer (P2P) transactions, where users can transfer tokens directly to another's wallet without intermediaries. The rising popularity of ADA has led to its adoption as a payment method in businesses, with some integrating ADA payment gateways for online purchases. Cardano charges an average fee of 0.19 ADA per transaction, which is calculated based on standard fees and transaction size. The unique eUTXO design of Cardano allows a single transaction to encompass multiple inputs and outputs, including ADA, native tokens, metadata, and smart contracts.

Users also have the opportunity to earn ADA through staking, by delegating their holdings to staking pools. This process is noncustodial and fully liquid, allowing users to contribute to transaction validation and confirmation in real-time. Staking rewards vary by pool, and users are advised to research thoroughly to maximize their returns. Importantly, pool operators neither control nor have access to the delegated tokens, and rewards are distributed automatically every five days by the Ouroboros protocol, ensuring security and transparency in the staking process.

Is Сardano really better than Ethereum?

Cardano and Ethereum, two prominent players in the blockchain arena, share a common vision of becoming the leading decentralized platforms for creating innovative tools and protocols. Charles Hoskinson, co-founder of Ethereum, parted ways with the project to address what he perceived as critical limitations in Ethereum's framework. He envisioned a blockchain that was inherently scalable and secure, qualities he believed Ethereum struggled to achieve.

Ethereum, despite its pioneering status and substantial market capitalization — over ten times that of Cardano — faces challenges related to scalability. The platform is currently undergoing significant upgrades, known as Ethereum 2.0, aimed at enhancing its scalability and overall performance. This transition marks a pivotal evolution in Ethereum's infrastructure, moving from a proof-of-work (PoW) to a more scalable proof-of-stake (PoS) consensus mechanism.

In contrast, Cardano was designed from the ground up with scalability and security as its foundational principles. Leveraging a scientific and research-driven approach, Cardano has differentiated itself by implementing a layered blockchain architecture and a unique consensus protocol, Ouroboros. This protocol not only addresses scalability and security concerns but also optimizes energy efficiency, a notable challenge in traditional PoW systems like the original Ethereum.

While Ethereum enjoys a significant market lead, partly attributed to its early start and established ecosystem, Cardano has been steadily gaining traction. Its focus on rigorous academic research, formal verification, and a phased development approach positions it as a formidable contender in the long-term race for blockchain supremacy.

Both platforms are continuously evolving, with Ethereum enhancing its infrastructure for better scalability and efficiency, and Cardano progressively unfolding its roadmap. The competition between these two platforms highlights the dynamic nature of blockchain technology and its potential to revolutionize various sectors by providing more secure, transparent, and efficient systems.
