Introduction to Smart Contracts
Smart contracts are self-executing contracts that use computer code to enforce agreements without intermediaries.
What is a smart contract?
Smart contracts were first conceptualized in the 1990s by pioneering cryptographer Nick Szabo, who described them as self-executing contracts that manage and enforce agreements between parties using computer code. Szabo’s groundbreaking vision, initially inspired by vending machines’ ability to take payment and dispense products without an intermediary, laid the foundation for smart contracts. However, it wasn’t until the advent of Ethereum, a blockchain platform introduced by Vitalik Buterin, that smart contracts became popular and well-known in the blockchain and cryptocurrency communities.
On the Ethereum platform, smart contracts are digital contracts that automatically execute predefined actions when specific conditions are met. This automation eliminates the need for intermediaries, greatly enhancing efficiency and trustworthiness in the process. Users pay for these transactions through gas fees, and the smart contracts self-execute once the predetermined criteria are met. As small computer programs stored within a blockchain, smart contracts are designed to automatically enforce their terms and conditions, bringing a new level of automation and precision to digital agreements.

How smart contracts work
Smart contracts follow an “if this, then that” structure, meaning that they execute specific actions based on predetermined conditions. For instance, they might transfer funds from one party’s wallet to another when certain conditions are met, such as inserting a cryptocurrency wallet address and network. Before a smart contract is created, all conditions for execution must be clarified, as smart contracts are not intelligent and must be programmed to respond correctly in every situation. The code for smart contracts is typically written using specific programming languages, like Ethereum’s Solidity, Vyper, or Bitcoin Script. However, several organizations using blockchain technology now offer simplified smart contract creation tools, like BlockApps Strato Mercata and the Remix Project. Once the code is ready, it is deployed on a blockchain, and the smart contract is initiated when the conditions are fulfilled. The smart contract then gets replicated through several blockchain nodes, benefiting from the security and immutability that the blockchain offers.
After deployment, smart contracts cannot be modified (except for Upgradable Smart Contracts); to update a smart contract, a new one must be created and deployed. As the transactions are irreversible and trackable, smart contracts provide enhanced transparency and security. The blockchain network’s distributed nature means that no single person can force the contract to release funds. This makes tampering with smart contracts almost impossible, creating a trustless environment for conducting transactions with anyone in the world.
Smart contracts can be applied to a wide range of industries and use cases, such as crowdfunding, where funds are held by the smart contract until a project reaches its funding goal. If the goal is met, the funds are automatically transferred to the project creator; otherwise, the funds are returned to the supporters. This eliminates the need for a third-party platform like Kickstarter and increases efficiency and trust in the process. Other applications include banking, insurance, postal services, and various decentralized platforms.
Advantages and use cases of smart contracts
There are several key benefits of smart contracts that make them a revolutionary concept in the digital world:
Elimination of middlemen: Smart contracts remove the need for intermediaries, leading to more cost-effective transactions.
Decentralization: By building smart contracts on top of blockchains, decentralized platforms can be created, reducing reliance on a single centralized entity.
Easy and affordable development: Platforms like Ethereum provide the infrastructure developers need to build transaction-based applications easily and inexpensively.
Enhanced security and transparency: As smart contracts are written in code, transactions are irreversible and trackable, ensuring greater transparency and security.
Self-enforcement: Smart contracts are self-enforcing, creating a trustless environment for conducting transactions with anyone in the world.
For example, a smart contract built on a blockchain like Ethereum could help benefit multiple parties by removing the middleman in a ride-hailing service like Uber. Instead of paying fees to a centralized entity, the smart contract would execute the transaction, and the gas fee paid to the Ethereum network would be smaller than the fee paid to Uber. This approach reduces overhead costs, as the data would be held on computers owned by individuals all over the world running the Ethereum network. Smart contracts have numerous potential applications across various industries, such as banking, insurance, and postal services. As more blockchains like Ethereum and Bitcoin support smart contracts, their use will continue to expand, paving the way for new innovations in the digital world.
