Decentralized applications (dApps) are becoming increasingly popular as more businesses and developers seek to leverage the benefits of decentralized networks such as blockchain. However, developing dApps can be complex and time-consuming. To simplify the process, developers can use frameworks that provide a set of tools and functionalities to test, compile, deploy and debug their applications. There are several popular frameworks for developing decentralized applications. In this article, we will explore the Cardano ecosystem and learn about the smart contract framework available to developers.

Cardano’s Plutus programming language is a high-level, functional programming language designed specifically for developing smart contracts on the Cardano blockchain. Plutus is based on the Haskell programming language, which is known for its mathematical precision and high degree of reliability.

Plutus is designed to be a secure and flexible language for developing smart contracts. It is used to write both on-chain and off-chain code that governs the behavior of smart contracts, allowing developers to create complex financial applications that can be executed on the Cardano blockchain.

Plutus offers robust support for formal verification. This unique feature allows developers to mathematically verify the correctness of smart contracts before deploying them to the blockchain. By removing vulnerabilities and bugs through formal verification, Plutus helps to enhance the security and reliability of smart contracts, reducing the risk of loss of funds or contract hacks.

There is a significant difference between Ethereum’s account model and Cardano’s eUTXO models. In the account model, all the logic is on-chain, but this has been found to
