This article aims to answer the question, “What is a smart contract?” and explore its possibilities in today’s digital world.

Key Takeaways

• Smart contracts are computer programs that automatically execute as parties fulfill their agreements’ terms, based on blockchain technology.
• Cryptocontracts were first introduced in 1994.
• Smart contracts can be employed in multiple industries, such as DeFi, real estate, healthcare, and others.
• Smart contract adoption requires continuous research, development, and collaboration with specialized companies and legal frameworks.

Smart Contracts Explained

Smart contracts (crypto contracts) are blockchain-based self-executing computer programs that automatically run as parties fulfill their agreements’ terms. The term “smart” in smart contracts refers to executing the agreement through computer programming code rather than paper or other forms. Smart contracts have multiple parts and can be governed by terms such as timing, expiration date, and voidability circumstances.

So, what are smart contracts in simple terms? They are digital instructions that automate specific tasks, ensuring timely and accurate execution. With the advent of blockchain technology, this concept has become a practical reality, making contracts not just written and signed but programmed, automated, and self-executed. This digital upgrade has marked a significant leap in handling agreements in the digital age.

Smart contracts are crucial for blockchain-based ecosystems, particularly in application-focused blockchains like Ethereum. These trustless, autonomous, decentralized, and transparent digital contracts reduce the need for intermediaries and contract enforcement in transactions. They are irreversible and unmodifiable once deployed, making them the building blocks of decentralized applications (dApps). Thousands of dApps across various blockchain networks utilize smart contracts in various ways, including trading, investing, lending, borrowing, gaming, healthcare, real estate, and corporate structures.

A smart contract is a distributed, decentralized, and autonomous system that ensures that all nodes connected to the network have a copy of the contract’s conditions. It is determined and immutable, meaning the final outcome remains unchanged regardless of who executes it. All nodes maintain and execute the contract, removing any controlling power from any one party. It is trustless, as third parties are not required to verify the process’s integrity.

The Bitcoin network was the first to use smart contracts for value transfers, employing basic conditions like checking if the amount of value is available in the sender account. Ethereum emerged later and became more powerful due to its ability to create custom contracts in a Turing-complete language. Common smart contract platforms include Ethereum, Solana, Polkadot, and Hyperledger Fabric, with Ethereum smart contracts being the most popular.

A Brief Overlook of Smart Contracts History

The term “smart contract” was first introduced by Nick Szabo, a US-born computer scientist and cryptographer, in 1994. Szabo defined them as digital transaction mechanisms that implement a contract’s terms and claimed that digital contracts are more functional than their paper-based counterparts, as they are digitally specified and include protocols for parties to perform on these promises.

Szabo took the vending machine as a prime example of how smart contracts work, as it automatically honors the terms of an unwritten agreement after a purchaser has satisfied the conditions.

Smart contracts also have origins in Ricardian Contracts, a concept published in 1996 by Ian Grigg and Gary Howland. Ricardian Contracts are a bridge between text contracts and code, with parameters such as being easily readable, parsable, digitally signed, carrying keys and server information, and allied with a unique and secure identifier.

The emergence of cutting-edge technologies, such as Ethereum, has spurred the rise of smart contracts, making them more accessible and prevalent platforms today.

Types of Smart Contracts

Today, several types of blockchain-based smart contracts exist.

Smart Legal Contract

Smart legal contracts, based on blockchain technology, are legally guaranteed and offer greater transparency than traditional contracts. They adhere to the “if… then…” structure, with parties executing contracts with digital signatures. Autonomous execution is possible if certain prerequisites are met, but failure could result in severe legal consequences.

Application Logic Contracts (ALCs)

ALCs are application-based codes that sync with other blockchain contracts, enabling interactions between devices like IoT and blockchain integration, and not between individuals or organisations.

Decentralized Autonomous Organisations (DAOs)

DAOs are democratic groups governed by smart contracts, serving as blockchain-governed organizations with shared objectives. They lack an executive or president, and their functions and fund allocation are regulated by blockchain-based tenets. VitaDAO is an example of this type of smart contract.

How Do Smart Contracts Work?

Smart contracts are digital contracts that follow a set of “if/when…then…” statements on a blockchain. These contracts execute actions when predetermined conditions are met, such as releasing funds, registering vehicles, sending notifications, or issuing tickets.

The blockchain is updated when the transaction is completed, ensuring only authorized parties can see the results. Participants must agree on transaction representation, rules, exceptions, and dispute resolution frameworks.

The process involves three steps:

1. Agreement

The parties must agree on the terms and conditions of the arrangement, including the criteria for fulfillment of the contract and whether it will execute automatically.

2. Contract creation

The parties have multiple options for creating smart contracts, ranging from coding them themselves to working with a smart contract developer. The smart contract’s security is crucial, and it must be fully verified during this step.

3. Deployment

The contract is broadcast to the blockchain, with the smart contract’s code included in the transaction’s data field. The contract is live on the blockchain once the transaction is confirmed and cannot be revoked or changed. The blockchain network stores the completed smart contract for review at any time.

Smart contracts are autonomous, relying on predefined rules, automating trust, and ensuring every party receives what they are promised.

Areas of Smart Contracts Implementation

Smart contracts have a wide range of applications across various industries.

DeFi

DeFi apps utilize cryptocurrencies and smart contracts to provide financial services without intermediaries, enabling complex processes like borrowing, lending, and derivative transactions.
