Smart Contracts with Plutus (Cardano)

Introduction about Cardano Smart Contracts

The landscape of blockchain technology is rapidly changing, and Cardano has well positioned to be a major leader in the race for innovation and functionality. One of the key turning points in Cardano’s journey was the Alonzo Hard Fork, when smart contracts came to the Cardano mainnet. After the Alonzo completed its ledger switch, developers were able to start developing and deploy smart contracts on the Cardano blockchain with a powerful and unique programming language, Haskell. In this blog, we will look into the world of smart contracts on the Cardano blockchain, learn about the Haskell programming language and how Cardano fits into the current technological landscape.

Smart Contracts: A Primer

Smart contracts are essentially self-executing or digital contracts where intermediaries are no longer necessary to grant validity to transactions, but instead rely on trust and transparency. Relying substantially on code, these contracts automate processes, executing predefined actions between transacting parties or the transfer of assets when predefined conditions are met.

Cardano’s blockchain is a smart-contract platform or blockchain collocatively designed to run scalable and fault-tolerant distributed applications (DApps). One of the unique characteristics of Cardano’s smart contract (currently referred to as Plutus) is its dual-layer design. It has on-chain validators responsible for executing and verifying smart contracts directly on the chain, and off-chain transaction building components that enable users to construct and interact with smart contracts off-chain. This design enables us to execute and validate smart contracts in a transparent and robust way, while also efficiently constructing and optimising those contracts and their interactions prior to on-chain execution, thus boosting the scalability of the network. Enormous computational complexity comes with decentralised computation, but as optimal data structures and algorithms become available, we expect numerous DApps and decentralised applications to emerge on the Cardano blockchain, utilising its unique dual-layer design. This dual-layer nature of Cardano embodies Cardano’s design philosophy for high and transparent security ensuring robust operations.

Programming Languages for Cardano Smart Contracts

Cardano offers developers three distinct languages for smart contract development:

• Marlowe: a domain-specific language (DSL) for expressing blockchain applications to deal with financial transactions. It provides enhanced guarantees to proved security, also providing finite certainty as well as golden guarantees of termination. Marlowe could be used to construct financial smart contracts and could enforce rules such as: deals closing have a finite lifetime. Deals must have some fixed number of time units during which they are effective. Nothing persists when a deal closes.
• Plutus: Plutus is the primary smart contract platform of Cardano, which executes smart contracts written in Haskell, the preeminent language for formal, fully predictable programming. Plutus allows developers to write smart contracts with immense power. With Plutus, many applications can be developed, such as token issuance, exchange, and trading, without having to go through full-fledged smart contract development exercises. You get an instant app, improved security, and speed in a box.Write your code, test it, and check if it passes the types. If it passes, it is being transformed into Plutus Core. What is the essence of this transformation process? Cardano’s smart contracts are potentially executable on the blockchain. Contracts are often highly complicated in nature. However, the Cardano blockchain can only accept one type of code to be executed – cannot ‘understand’ every single higher-level human language. During the development process, you write your contracts in Plutus, a higher-level human-sounding language. Once it is type-checked, it is then transformed into Plutus Core, a lower-level language the Cardano blockchain can accept and execute. Plutus Core is machine-ready code that the blockchain can easily accept and execute. This transformation acts as a bridge to execute high-level contract logic in a secure and timely manner, without invalidating the security and integrity of the Cardano blockchain. The image below depicts a well-defined, yet simple, description of the transformation from Plutus to Plutus Core.
• Haskell: The core language of Plutus and Marlowe, and a purely functional programming language with a reputation for high-assurance code, Haskell is chosen for strong code correctness in smart contracts on Cardano.

Creating Cardano Smart Contracts

Developing smart contracts on Cardano involves a structured process with eight distinct steps:

1. A Backgrounder: Define the Smart Contract: Begin by outlining the purpose and functionality of your smart contract. Determine what kind of assets or operations it will manage, and identify the conditions or rules it should enforce.
2. Install Development Tools: Ensure your machine is setup with the necessary tools to write and compile plutus applications.
3. Writing Plutus Code:
   • Basic Structure: Create the basic structure of your contract, from importing the necessary modules, to defining the basic data types used in the contract.
   • Logic contract: Write the logic of your smart contract in Plutus. Define functions and data structures that specify the behaviour of your smart contract, the movement of assets, and the permissions and rules that it implements.
4. Type checking: Use the development tools to check your code for type errors. Plutus has a rich type system to help you catch errors early.
5. Testing: You’ll need to write test cases to ensure that your smart contract behaves properly. You can run the contract in various scenarios.
6. Compile to Plutus Core: After you have created your Plutus code and tested it for errors, you must convert it to Plutus Core, which is the language that the Cardano blockchain understands. The conversion from Plutus to Plutus Core is usually accomplished using development tools.
7. Restore on the Cardano Network: Restore your compiled Plutus Core code to the Cardano network. This is typically done through a transaction containing the contract code, along with any starting funds or parameter it might need.
8. Engage with the Contract: users can now interact with your smart contract running on the Cardano blockchain, through transactions, invoking contract functions, and interacting with its blockchain state.

At every step of the way, it is useful to comment your code, make sure you’re following industry best practices for security and performance, and think about how your smart contract might impact the Cardano ecosystem as a whole, in terms of the network’s ability to scale and use its resources. You’ll want to stay up to date with changes and updates in the Cardano ecosystem in order to keep your smart contract humming along.

What Sets Cardano Apart?

Cardano distinguishes itself from other blockchain platforms through several key features:

• Peer-Reviewed Research: Cardano’s research is based in peer-reviewed research so that means the highest levels of engineering and security are asserted in the development of Cardano.
• Significant robustness and correctness: that is important for the first `Advanced Financial Technologies` contract engine on a blockchain: the Haskell Language. Cardano smart contracts are written in Haskell and operators can make the move instantly. This gives Cardano huge security and trust benefits.
• Rich Type System: Haskell’s static types ensure that code is mistake-free at compile-time and thus better-quality and more dependable.

Use Cases of Cardano Blockchain

Cardano’s smart contract capabilities open up a world of possibilities, including:

• NFT Marketplaces: Write an NFT marketplace on Cardano to take a share of the NFT trend.
• Cardano Architecture DeFi. Applications: Typically, DeFi applications for DEXs, Stablecoins, Lending protocols , Synthetics DeFi Development can be developed more effectively and efficiently on the Cardano’s novel architecture.
• DApps in practically every category from DeFi to gaming can run on Cardano. Cardano has many smart contract-supporting projects already supporting people to build useful and user-experience-friendly applications.

The Birth of Aiken: Simplifying Smart Contract Development

designed to simplify and improve smart contract development on Cardano while supporting an easy-to-learn syntax, integrating with others tools and languages, and offering state-of-art functionality, Aiken serves as the high-level language we need to breach the complexity gap between the programming languages of the cutting edge and truly developer-friendly platforms such as Rust and Elm. Aiken is cool. But, it could well be some time before we see the mass adoption of Aiken and also Plutus, the new ‘programming language’ for smart contracts on Cardano. While we wait, what exactly do we mean when we invoke the term ‘new programming languages’ in private blockchains?

Conclusion

Cardano’s Alonzo Hard Fork is driving smart contract development onto its blockchain, and Plutus built on Haskell is leading the charge. Cardano’s high-assurance code and its emphasis on peer-reviewed research makes it a trustworthy bastion for organisations and developers. With Aiken evolving to be part of the Cardano ecosystem, developers have an even stronger reason to choose the Cardano network for their smart-contract projects to safely bring them to life. Cardano ecosystem is developer-friendly and it’s as good as time as any to go onchain! The future of Cardano and smart contract development looks bright. With the continuous evolution of the Cardano ecosystem, it’s likely to attract many developers who seek a robust and reliable smart-contract platform for their projects.
