A smart contract is a self-executing contract whose terms of the agreement between the contract’s counterparties are embedded into lines of code. Essentially, a smart contract is a digital version of the standard paper contract that automatically verifies fulfillment and enforces and performs the terms of the contract.The concept of smart contracts was proposed by Nick Szabo, an American computer scientist and researcher of digital currencies, in 1994.
The smart contract is executed through a blockchain network, and the code of the contract is replicated on many computers that comprise the network. This ensures a more transparent and secured facilitation and performance of the contractual terms.
Moreover, smart contracts do not require amiddleman to execute because the code of a smart contract is verified by all the participants in the blockchain network. The removal of the middleman from the contract helps to substantially reduce the costs for counterparties.
Smart Contracts and Blockchain
The concept of smart contracts is primarily based on the idea of blockchain technology.
A blockchain is a decentralized network of a growing list of records (blocks) that are linked through cryptography. A blockchain network does not include a single central point like a conventional database. The data that is stored in the blockchain is shared between all the computers that comprise the network. Therefore, the network is less exposed to possible failures or attacks.
In addition, in a blockchain, a record in one computer cannot be altered without changing the same record on other machines in the network. Transactions executed through a blockchain are grouped in blocks that are linked in a chain. A new block is created only when the previous block is completed. The blocks come in a linear chronological order, and each block contains a cryptographic hash of the previous block.
How Do Smart Contracts Work?
First, the contractual parties should determine the terms of the contract. After the contractual terms are finalized, they are translated into programming code. Basically, the code represents a number of different conditional statements that describe the possible scenarios of a future transaction.
When the code is created, it is stored in the blockchain network and is replicated among the participants in the blockchain.
Then, the code is run and executed by all computers in the network. If a term of the contract is satisfied and it is verified by all participants of the blockchain network, then the relevant transaction is executed.

Smart contracts are typically used to automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary's involvement or time loss. They can also automate a workflow, triggering the next action when predetermined conditions are met.
They simplify business and commerce between anonymous, identified parties, usually without the need for an intermediary. They also reduce the formality and costs associated with traditional methods while preserving credibility, security, and authenticity.
Creating a smart contract may seem complex, but it's surprisingly straightforward. It's all about encoding an agreement, which then executes itself. This eliminates the need for intermediaries, providing a secure, transparent, and efficient method of carrying out transactions or agreements.
The idea behind smart contracts is to automate the execution of agreements, cutting out the need for intermediaries such as lawyers, notaries, or banks. This automation is expected to reduce costs and minimise the potential for human error, making transactions more efficient and trustworthy.
Conclusion. Smart contracts have the potential to revolutionize various industries by enabling automation, trust, and efficiency. However, their development is fraught with challenges, including complexity, coding errors, security vulnerabilities, and legal uncertainties.
Ultimately, a smart contract can be legally binding, but it may not have to be if it is not intended to serve the same purpose as a traditional contract. In this regard, the “meeting of the minds” between the contracting parties will play an integral role in its interpretation.
Since smart contracts are the cornerstone of blockchain applications, when they fail, the applications built with those contracts fail, and the entire ecosystem suffers. Smart contracts are honeypots that attract hackers.
Examples of smart contract applications include financial purposes like trading, investing, lending, and borrowing. They can be used for applications in gaming, healthcare, and real estate; and they can even be used to configure entire corporate structures.
Although it's possible to find a smart contract development company ready to help you for nearly $500, the price may reach even more than $5,000. The deployment costs directly depend on the complexity of the project.
But what happens if someone breaks a smart contract? Marcushamer notes, "Because smart contracts are a type of contract, from a legal perspective if they were to be broken, all remedies that are available for traditional contracts would be applicable."
Typically, blockchain developers are the ones creating smart contracts, using their expertise in coding languages and frameworks like blockchain. However, thanks to the wealth of resources available, anyone can become a developer and enter the world of writing smart contracts.
The top 10 best smart contract platforms in 2024 are Ethereum, Binance Smart Chain (BSC), TRON, Arbitrum, Cardano, Solana, Polygon, Algorand, Avalanche, and Tezos.
It might seem complex if you have no experience or understanding of smart contracts. However, it's not hugely different conceptually from a traditional written agreement.
Crucially, a smart contract's code cannot be changed once it has been deployed. There are some ways around this, including proxy smart contracts, but once a piece of smart contract code has been added to the blockchain there's no practical way to stop or delete it. The code runs autonomously, forever.
Smart contracts eliminate intermediaries by automatically enforcing terms once conditions are met. Think of a smart contract like a vending machine. When you insert a dollar, you get a co*ke. The machine follows built-in rules, similar to if-then statements in code.
Smart contracts exist in an electronic or digital form. Smart contracts are designed to automatically execute when predetermined conditions are met. The conditions are generally expressed in the logic of “If x occurs, then y executes” – creating a binary outcome.
On blockchain, the goal of a smart contract is to simplify business and trade between both anonymous and identified parties, sometimes without the need for a middleman. A smart contract scales down on formality and costs associated with traditional methods, without compromising on authenticity and credibility.
Smart contracts are scripts that automate the actions between two parties. Smart contracts do not contain legal language, terms, or agreements—only code that executes actions when specified conditions are met. "Smart contract" is somewhat of a misnomer—these programs are neither smart nor a contract.
