This article will give you a detailed overview of the Cardano development process and tips on hiring the best Cardano developers for your project.
What Are Cardano and ADA?
Cardano is often hailed as the third generation of cryptocurrency, after Bitcoin and Ethereum. It was founded in 2015 by Charles Hoskinson, who is also one of the co-founders of Ethereum.
Cardano is built on the Haskell programming language and uses Ouroboros's unique Proof-of-Stake (PoS) consensus algorithm.
The Cardano network aims to solve some of the significant problems facing Bitcoin and Ethereum, such as scalability, sustainability, and interoperability. While these are the basics, it's imperative to learn more about Cardano development before using the blockchain for smart contracts.
More About Cardano Development: How Does the Blockchain Work?
Cardano has multiple chains running in parallel. The primary chain is called the Cardano Settlement Layer (CSL) and is used for transactions and value transfers. The CSL is similar to Bitcoin in this regard.
The second layer of the Cardano blockchain is known as the Cardano Computation Layer (CCL). This layer enables smart contracts and decentralized applications (DApps) to be built on the Cardano blockchain.
The Ouroboros consensus algorithm validates transactions and produces new blocks on the CSL. The algorithm does not require miners or stakers, making it more energy-efficient than the Proof-of-Work (PoW) consensus algorithm used by Bitcoin.
Cardano Settlement Layer (CSL)
The Cardano Settlement Layer is the first layer of the Cardano blockchain and is responsible for accounting and transaction settlement. In addition, this layer is a value ledger for ADA, the native cryptocurrency of the Cardano blockchain.
The CSL is based on the PoS consensus protocol called Ouroboros, which allows users to stake their ADA to validate transactions and earn rewards.
Cardano Computation Layer (CCL)
The Cardano Computation Layer is the second layer of the Cardano blockchain and is responsible for running smart contracts. The layer is Turing complete, meaning that it can run any program.
A Turing-complete programming language called Plutus is used to write smart contracts on the CCL. Plutus is based on the functional programming language Haskell.
Why Use Cardano for Blockchain Development?
Cardano has been designed to be a more general-purpose blockchain platform than Ethereum, focusing on scalability and improved security features. In addition, the blockchain is being developed in a scientific manner by InputOutput Global (IOG), with its development process informed by peer-reviewed research publications written by IOG scientists and engineers.
The vision for Cardano is to create a blockchain platform that is capable of handling more complex applications than any protocol previously developed and that meets the needs of a global user base with a wide range of varying requirements.
Since it's a multilayer blockchain, Cardano gives the network flexibility regarding future upgrades. For example, the CSL will allow fiat currency to be transferred on the blockchain, while the CCL will be used for voting and stakeholder management.
The Cardano team is constantly working on developing new features and improving the platform. Here are some benefits of using Cardano for blockchain development.
Unlike many other blockchains merely supported by a white paper, Cardano is based on peer-reviewed research. The development team publishes their research papers in well-respected journals such as Nature Climate Change, IEEE Security & Privacy, and the Internet Protocol Journal.
This ensures that the Cardano platform is constantly being improved upon and that new features are rigorously tested before being implemented. Furthermore, computer scientists from all over the world have verified Cardano's features, supporting its role as the Internet of blockchains.
Cardano has a unique architecture that allows the network to be easily upgraded. For example, if a new consensus algorithm is needed, it can be implemented on the Settlement Layer without affecting the Computation Layer. In addition, users can continue to use the platform while upgrades are being made.
The modular approach also makes it easier for developers to create innovative applications on Cardano. They can pick and choose which features they need without using the entire platform.
Cardano uses the Proof-of-Stake consensus algorithm called Ouroboros, which is more secure than the Proof-of-Work algorithm used by Bitcoin. With Ouroboros, users can stake their ADA coins to help secure the network and earn rewards.
Since Ouroboros doesn't require mining, it's more energy-efficient than Proof-of-Work. It also means that there's no risk of a 51% attack, which is when a group of miners control more than half of a network's hash power and can double-spend coins or prevent other transactions from being confirmed.
Cardano uses a data structure called a Recursive Internetwork Architecture (RINA) to improve scalability. RINA allows for an unlimited number of users to interact with the network without each user needing their own copy of the blockchain.
It also uses a technique called "Sharding" to improve scalability. Sharding is a process of dividing the network into smaller pieces, which allows each piece to be processed independently. Thus, the Cardano network can theoretically scale infinitely and be able to handle billions of transactions per second.
Support for Foundational Changes
Cardano is robust enough to handle significant changes, such as a "hard fork." A hard fork is when a cryptocurrency splits into two separate coins, usually due to disagreements among the developers or community.
For example, when Ethereum forked into Ethereum and Ethereum Classic, both coins functioned independently. Cardano is designed to allow for a similar event to occur without disrupting the entire network.
Cardano Developer Skills: Top Skills Needed for ADA Development
Developers can create smart contracts on the Cardano blockchain. Cardano development is a little different from developing for other blockchains. To be a good Cardano developer, developers need some specific skills.
Familiarity with Ouroboros
The Ouroboros PoS consensus mechanism is different from the mechanisms used by Ethereum and Bitcoin because it is less energy-intensive. When you hire Cardano developers, they need to understand how Ouroboros works.
As per Cardano's website, there are different Ouroboros implementations that developers should know about. In addition, developers should understand the technical specifications of the following:
- Genesis: Genesis is the very first block in the Cardano blockchain. The protocol was first proposed in the white paper "Ouroboros: The Blockchain Protocol."
- Byzantine Fault Tolerance: This is a type of consensus that can be achieved even when some network participants are not functioning correctly.
- Ouroboros Praos: Praos is an improved version of the Ouroboros protocol that offers security against corruption in a semi-synchronous network.
Developers should also be familiar with the Cardano wallet Daedalus. Daedalus is a cryptocurrency wallet that supports ADA, the native token of Cardano. The wallet is available for Windows, macOS, and Linux.
Programming is among the most essential Cardano developer skills since developers will be writing code for smart contracts. Therefore, they should be familiar with at least one programming language. The two most popular languages for Cardano development are Haskell and Plutus.
Haskell is a statically typed, purely functional programming language with type inference and lazy evaluation. On the other hand, Plutus is a smart contract language based on Haskell.
Other essential skills for Cardano developers include an understanding of formal verification and security-focused programming.
Formal verification is a mathematically rigorous method of ensuring that a system meets its specifications. It is used to verify the correctness of software and hardware systems.
Meanwhile, security-focused programming is a type of programming that takes security concerns into account from the start. It involves writing code that is secure by design.
Experience Using Truffle
A Cardano developer should also have experience using Truffle, a popular development environment for Ethereum. Truffle allows for automated testing, debugging, and deployment of smart contracts.
It also comes with an interactive console that makes it easy to develop Solidity smart contracts.
Familiarity with Integrated Development Environments
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development.
For instance, the Eclipse IDE is a popular choice for developing smart contracts on Ethereum. This is because it has excellent support for Solidity and allows for the creation, compiling, testing, and deploying of smart contracts.
The Atom IDE is also a good choice for developing Solidity smart contracts. It has syntax highlighting and code completion for Solidity.

Understanding of Command Line Interface
The command-line interface (CLI) is a text-based interface used to view, run, and debug smart contracts. The CLI is a vital tool for a Cardano developer because it allows for executing commands on a blockchain. It also allows for the creation of new accounts, the sending of transactions, and the viewing of account balances.
Proficiency in Higher-Level Programming Languages
Moreover, developers can use two other programming languages for Cardano development. These are:
- Marlowe: Marlowe is a domain-specific language used for developing financial contracts.
- Glow lang: Developers should also know how to use Glow lang, especially if you want them to create dApps for your organization. This language is specifically used for creating decentralized applications.
