    1. Introduction

    In the rapidly evolving landscape of blockchain technology, smart contracts have emerged as a transformative force, revolutionizing industries and reshaping the global market. These self-executing contracts with predefined rules have disrupted traditional business processes, offering unprecedented levels of automation, transparency, and security.

    The impact of smart contracts on the global market has been nothing short of remarkable. According to a recent report by Fortune Business Insights, the global smart contracts market size was valued at $1.71 billion in 2023 and is projected to reach a whopping $12.77 billion by 2032, growing at a CAGR of 24.7% from 2024 to 2032. This explosive growth underscores the increasing adoption of smart contracts across various sectors, including finance, healthcare, real estate, and supply chain management.

    However, the foundation of these groundbreaking smart contracts lies in the smart contract programming languages used to create them. Without powerful, secure, and versatile smart contract languages, the potential of smart contracts would remain untapped. These smart contract programming languages serve as the building blocks for developing complex, autonomous agreements that can execute transactions, manage assets, and enforce contractual obligations without intermediaries.
