Smart Contracts: A Quick Beginner’s Guide on What to Know

Smart contracts are an innovative technology that has the potential to revolutionise the way we do business. Smart contracts are self-executing digital contracts that are written into computer code and stored on a blockchain. They help to automate the execution of an agreement between two or more parties without the need for a third-party intermediary.

What Is a Smart Contract?

Smart contracts are self-executing contracts that are written in computer code and stored on a blockchain. They are designed to automate a variety of processes, such as payments, transfers, and other exchanges of value. Smart contracts are immutable, meaning they cannot be changed or deleted once they are published on a blockchain network. This makes them a secure and reliable way to transact business.

Smart contracts are programmed to execute a set of instructions when certain conditions are met. These conditions are defined in the contract code and the code itself is written in a programming language that is compatible with the blockchain platform. Once the conditions are met, the contract automatically executes the instructions written in the code. This makes it possible to execute a wide variety of transactions without the need for manual intervention or expensive intermediaries.

Quick History of Smart Contracts

The concept of a “smart contract” was first introduced by Nick Szabo in 1994. Szabo, a computer scientist and legal scholar, proposed the idea of a digital contract that would be self-executing, meaning that it would automatically execute its terms without the need for manual intervention.

The idea of a smart contract was further developed by the Ethereum project, which was launched in 2014. Ethereum is a blockchain-based platform that enables the development of decentralised applications and smart contracts. Ethereum has made it possible for developers to create and deploy smart contracts on the blockchain, allowing for secure, transparent, and immutable contracts that cannot be tampered with.

Today, smart contracts are being used in a wide range of applications, from real estate to finance to healthcare. Smart contracts are being used to automate a variety of processes, from loan agreements to insurance claims to supply chain management. They also have the potential to revolutionise the way we do business by eliminating the need for manual paperwork and allowing for faster and more secure transactions.

How Does a Smart Contract Work?

Smart contracts are used to automate tasks and transactions on a blockchain network. A smart contract contains a set of rules that are written in code and stored on the blockchain network. When the conditions of the contract are met, the code is automatically executed and the contract is enforced.

Smart contracts allow parties to enter into an agreement without the need for a third party, such as a lawyer or a bank. The code is self-executing and can be used to transfer assets, store data, and create new digital assets. Smart contracts can also be used to create and manage digital assets, such as tokens, which can represent different assets, such as stocks and bonds.

In order to create a smart contract, the parties must first define the terms and conditions of the contract. The code is then written, tested, and stored on the blockchain network. Once the code is stored, the contract is ready to be used.

When a party wants to use the smart contract, they must send a transaction to the blockchain network. The transaction contains information about the conditions of the contract and the code that is used to enforce the contract.

Once the transaction is sent, the code is executed and the contract is enforced. The transaction is then recorded on the blockchain as a record of the contract and the transaction.


Smart contracts are computer programs that are used to facilitate and execute the performance of contracts online. They can be used to automate the transfer of money, property, shares, or anything of value in a transparent, conflict-free way while avoiding the services of a middleman. Smart contracts are self-executing and are enforced with cryptographic code, meaning that they are virtually impossible to tamper with or manipulate. Smart contract technology has the potential to revolutionise the way that we do business and is an incredibly powerful tool in the world of digital transactions.
