As a seasoned technology enthusiast and a professional who has witnessed the evolution of digital platforms over the years, I am truly captivated by the potential that smart contracts hold for our future. Having worked with various blockchain projects and observed their transformative impact, I can confidently say that they are set to redefine industries far beyond finance and legal sectors.
As technology in information systems (IT) continues to evolve and blockchain networks become more prevalent, a novel form of agreement has come into existence – self-executing contracts, commonly known as smart contracts.
In this article, we’ll explore smart contracts and how they’re being used today.

What are smart contracts. Smart contracts explained
A smart contract can be thought of as an autonomous digital accord, where the rules and conditions are embedded within the program’s code itself. This contract is self-executing and self-enforcing, living on a blockchain network. Once the predefined conditions are fulfilled, the contract automatically carries out its terms without human intervention.
In essence, smart contracts within cryptocurrencies simplify and fortify transactions by eliminating the necessity for intermediaries such as lawyers or banks. This is due to the fact that the rules governing these contracts are clear and cannot be altered once implemented. Smart contracts facilitate faster, more effective, and less dependent transactions on external oversight.
Historical background
The concept of smart contracts dates back to the mid-1990s when computer scientist and cryptographer Nick Szabo first proposed the idea.
He envisioned a digital protocol that could automatically execute the terms of a contract when predefined conditions were met, similar to a vending machine dispensing a snack when the correct amount of money is inserted.
It was only after the advent of blockchain technology, notably with Ethereum‘s launch in 2015, that smart contracts gained traction. With Ethereum’s blockchain, developers were equipped to construct and execute self-executing code capable of managing intricate agreements autonomously. This innovation sparked a surge of new decentralized applications, disrupting the status quo by automating transactions and thereby eliminating the need for intermediaries.
How do smart contracts work
Smart contracts function utilizing clear “if-this-then-that” directives embedded within a blockchain network. They autonomously manage tasks such as dispensing funds, recording assets, or issuing alerts when predefined conditions are fulfilled. The inherent durability of the blockchain ensures that transactions remain accessible exclusively to authorized entities.
Smart contracts can become quite intricate, requiring consensus on numerous conditions. This implies determining the method of transaction recording, managing unexpected occurrences, and finding solutions for potential disagreements.
Each node within the network maintains a replica of every smart contract together with the blockchain and transaction details. Whenever a contract acquires funds, all nodes run the contract’s code in unison to reach a consensus about the outcome. This ensures seamless operation without the need for a central governing body.
It’s beneficial to understand which blockchains support automated contracts and which don’t, because not all of them can do so. For instance, Ethereum, Arbitrum, Avalanche, Base, and BNB Chain are among those that can, while Bitcoin‘s base chain is not. The key distinction lies in the ability to handle and store complex logic. Once a smart contract is established on these platforms, it typically remains unchanged, regardless of who created it. This stability offers protection against censorship and makes it harder for such contracts to be easily taken down.
Types of smart contracts
Smart contracts in blockchain generally fall into three types:
Smart Legal Contracts
Intelligent Legal Contracts mimic traditional legal agreements in a digital format, implying that all participating parties bear legal responsibility for adhering to the contract’s conditions. They cover a wide spectrum of uses, including transactions involving cryptocurrency-to-fiat exchanges and property registrations related to real estate.
A significant number of currently used smart contracts have a legal basis, serving as the foundation for several digital services such as cryptocurrency trading platforms, Decentralized Finance (DeFi) initiatives, gaming platforms on the blockchain (GameFi), and online markets for Non-Fungible Tokens (NFTs) and real estate tokenization.
Decentralized Autonomous Organizations
In simpler terms, Decentralized Autonomous Organizations (DAOs) are groups of people who follow rules written in computer code, or smart contracts. These rules determine how the organization operates, offering protection, enforcing decisions, and imposing consequences for rule-breaking. To put it another way, these smart contracts serve as the DAO‘s laws and digital administrative system.
In the projects such as Decentraland, Uniswap, Polkadot, and MakerDAO, decision-making processes (or governance) are handled by individuals who own the native tokens. These token holders can propose modifications like tweaking fee structures, editing blockchain code, or even deciding on the addition/removal of certain components (like parachains in Polkadot). Smart contracts called DAO (Decentralized Autonomous Organizations) manage and tally these votes.
Application Logic Contracts
Automated Logic Controllers (ALCs) function under a guiding software and are mainly responsible for overseeing communication between this software and the blockchain. For example, ALCs could help in connecting Internet of Things (IoT) devices to the blockchain.
Benefits of smart contracts
The advantages of using blockchain are impressive for individuals, businesses, and governments.
One major advantage is the aspect of openness. Each transaction on a blockchain is accessible to all and verifiable, so once information is inputted, it remains unaltered. This ensures that smart contracts are secure and haven’t been manipulated, providing reassurance whether they’re used for personal or business purposes.
Economical Effectiveness of Smart Contracts: Smart contracts significantly simplify the process of establishing and overseeing agreements by executing many tasks automatically. By eliminating the need for intermediaries such as lawyers, financial institutions, or brokers, they not only reduce costs but also enhance efficiency in processes.
Establishing Confidence: Since smart contracts operate automatically, they minimize the potential for human mistakes, thereby fostering confidence among involved parties.
Safe Data Preservation and Recovery: The loss of data can pose a significant threat to any organization. Although backups are crucial, they’re not always infallible. However, blockchain technology, by distributing data across multiple nodes, significantly reduces the chances of data loss or manipulation, as long as the blockchain network remains active.
Safety Aspect: Smart contracts boast an impressive level of safety due to robust encryption techniques and stringent security measures. They serve as highly secure instruments for managing transactions, providing significant resistance against cyber attacks and manipulation, much like cryptocurrencies.
Use cases
In the realm of cryptocurrencies, smart contracts (or token contracts) serve as templates for creating, controlling, and designating ownership of unique digital assets across blockchain platforms. These contracts essentially define the capabilities of the tokens they generate, thus assigning diverse functions to them.
These could empower tokens to function as utility tokens for apps (providing features or perks within an app), governance tokens that grant holders decision-making authority within a system, security tokens reflecting shares in a corporation, or NFTs symbolizing ownership of exclusive physical or virtual possessions.
Smart contracts examples
Examples of smart contracts in action:
Ethereum serves as a platform where developers can create decentralized applications (dapps) and is the foundation for numerous DeFi projects. The smart contracts on Ethereum are incredibly versatile, managing tasks ranging from converting real-world assets into digital tokens to automating transactions. Essentially, it’s a bustling center for innovative blockchain activity.
Additionally, there’s the highly acclaimed Binance Smart Chain. Known for its swiftness and effectiveness, it shares compatibility with Ethereum but boasts lower transaction fees and superior performance. This makes it an excellent option for numerous projects. It has gained popularity among DeFi projects and tokenization initiatives thanks to these benefits.
Polkadot serves as a platform for linking multiple blockchain networks together. By enabling the creation of parallel chains, it facilitates interaction between these networks and offers support for smart contracts across various use cases, thereby improving the interconnectivity of blockchains.
Chainlink serves as a link between smart contracts and the real world, supplying them with outside data. By means of its decentralized oracles, these contracts are able to retrieve current data, thereby enhancing their flexibility and responsiveness.
Future of smart contracts
The prospect for smart contracts shines with great promise as technology advances, making them increasingly intelligent, secure, and streamlined. This progress is largely due to continuous advancements in blockchain technology and the development of superior coding tools.
It’s quite probable that smart contracts will significantly transform numerous sectors past finance and law, impacting regions such as supply chain management and administrative operations of governments. In essence, smart contracts are positioning themselves to play a pivotal role in determining the shape of our digital future.
