What is smart contract development? How does it work?

A smart contract is a remittance protocol, a pre-programmed circumstance or action on a blockchain. The goal of a smart contract is to automate the control, implementation, as well as documentation of events in accordance with the terms of the agreement. As a result, fewer intermediaries and arbitrageurs are required, and fraudulent schemes are greatly diminished. The creation of dApps requires the use of smart contracts. They also contribute significantly to the development of a decentralised network. 

Nick Szabo first put forth the idea of smart contracts in 1994. Szabo, a cryptographer and legal expert, is credited with creating the foundation for digital currency. Because there was no online platform as well as distributed ledger system that could enable smart contracts back then, there was very little interest in or activity surrounding them. The distributed ledger blockchain technology that underpins the bitcoin cryptocurrency was created in 2008 and uses it to track financial transactions. The creation of smart contract code, which is used to add the contract's terms to the blockchain, was made possible by this technology.

What is a smart contract?

One of the core components of decentralised finance is a smart contract. Long before Web 3.0 was fully implemented, cryptographer Nick Szabo first used the term "smart contract" in 1994 to describe "a bundle of commitments in a digital format." A smart contract cannot be compared to an online legal contract, even though it is a digital contract rather than a paper one. Of course, there are several kinds of these contracts, but that is not the topic at hand. A decentralised programme known as a smart contract runs business logic in response to events. Executing a smart contract can lead to an exchange of funds, the provision of services, the release of digitally locked content, or other sorts of data manipulation, such as changing the name on a land title. Additionally, smart contracts can be used to enforce privacy protection by, for instance, enabling the selective release of data that is privacy-protected in order to comply with a particular request.

The programmes that support smart contracts can be created, distributed, managed, and updated using a number of architectures. They can be included in different payment methods and digital exchanges, including those that accept bitcoin and other cryptocurrencies, and stored as a component of a blockchain or other distributed ledger technology. Smart contracts, despite their name, are not enforceable contracts. Their primary duty is to programmatically carry out business logic, which has been encoded into them to carry out certain tasks, processes, or transactions in response to a specific set of criteria. To connect this execution to legally enforceable agreements between parties, legal action must be done.

How do Smart Contracts work? 

Smart contracts operate on the tried-and-true "if/when...then" condition. Once the condition is satisfied, the blockchain is updated, making it impossible to change the transaction and limiting access to the results to parties who have been granted permission. Participants must decide how transactions as well as their data will be portrayed on the blockchain, come to an understanding on the rules that apply to those transactions, look into exceptions, and decide how disputes will be resolved before they may create conditions. Using a smart contract in the healthcare industry is one of the most natural implementations. Information security in EHR/EMR is crucial since it can affect a patient's life in the medical setting.

The decentralised medical network serves as a good illustration, issuing its tokens to enable smart contracts involving healthcare providers and patients. On the basis of Ethereum blockchain smart contracts, this solution enables users to interact and manage collaboration. Additionally, all patient contacts, performance indicators, and patients' perceptions of their interactions with healthcare professionals are tracked by the digital contracts.

Benefits of smart contracts

The use of smart contracts has a number of possible commercial benefits.

Cost effectiveness

 Smart contracts offer to automate cross-organizational business operations. This can reduce costs associated with running the business and free up resources like the staff required to keep an eye on a complicated process that responds to external factors affecting several organisations.

Processing velocity

Business operations that span numerous businesses can be processed more quickly thanks to smart contracts.


Smart contracts eliminate the need for a third party to oversee business-to-business transactions because they are carried out automatically by the network.


A verifiable record of every activity associated with the execution of complicated processes can be maintained by smart contracts using blockchain ledgers as well as other distributed ledger technologies, and this record cannot be modified after the fact. Additionally, it offers automated transactions that guarantee correctness in contract execution and do away with the possibility of human error.

Smart contracts' potential for growth

The promise of smart contracts extends beyond the straightforward transfer of assets and they are complicated. They have the ability to carry out transactions in a variety of areas, including legal proceedings, insurance premiums, crowdfunding agreements, and financial derivatives. By streamlining and automating ordinary, repetitive operations for which individuals currently pay banks and lawyers significant fees, smart contracts have the potential to eliminate middlemen from the legal and financial sectors.

As smart contracts develop skills like adjudication of conventional legal contracts or even customizable smart contract templates, the role of lawyers may also change in the future. Additionally, smart contracts' potential for real-time auditing including risk assessments, as well as their capacity to manage behaviour in addition to automating procedures, can be advantageous for compliance.

The potential of smart contracts to automate IoT as well as edge computing activities is also apparent. For instance, a utility firm might provide a system in which smart contracts operate in tandem with devices installed into power metres to respond to changes in electricity prices. For instance, a smart contract may use a properly programmed IoT controller to automatically switch off or reduce power-hungry items like air conditioners when prices exceed a specified threshold.

So, Smart contracts can currently be used on a wide range of platforms, including Ethereum, Hyperledger, Tezos, and Corda. Smart contracts are becoming more and more common as a result of the increasing use of bitcoin and indeed the assistance of blockchain technologies.
