The question of what is a smart contract might be lingering in your mind. Smart contracts are programs kept on a decentralized ledger that run when agreed states are met. They help execute a contract so that all parties can be sure of the result without involving third parties. By eliminating intermediaries from a transaction, you reduce the cost of doing business. Furthermore, smart contracts reduce the time of completing a transaction.

What is a smart contract in blockchain?

An experienced developer understands ‘what is a smart contract’ and can help you create a digital agreement that meets the needs of your project. Here, we explore what is a smart contract and explain the leading platforms to where to make it.

One of the prominent search phrases on the web is ‘What is a smart contract’? Smart contracts have become popular, and many people want to understand what they entail.

Smart contracts are self-executing agreements that run on the blockchain ecosystem. They are led by plain terms and conditions written on them. These digital contracts facilitate the exchange of cash, shares, content, and any valuable item. For example, the nft smart contract enables the sale of digital collectibles. Also, smart contract crypto is used to facilitate transactions during ICOs. The self-enforcing manner of these digital contracts offers a tremendous chance for application in any industry that depends on data-based settlements.

What are the advantages of using smart contracts?

Once you understand ‘what is a smart contract,’ the next step is to explore why virtual contracts are essential. The following are perks to enjoy when using smart contracts:

  • Accuracy: What is a smart contract without mentioning accuracy? Accuracy is a crucial element when conducting transactions. Smart contracts help to evade errors of manually filling out multiple forms.
  • Transparency: each party accesses the terms and conditions of the smart contract crypto, minimizing disputes once the transaction is complete.
  • High speed: smart contracts are automated. This means that transactions happen quickly.
  • Safety: the high level of encryption makes these contracts safe for different transactions.
  • Cost-effective: they eliminate the need for third parties.

Smart contract examples

Wondering what are smart contracts used for various industries? Digital contracts can transform many fields, such as healthcare, finance, elections, and insurance. That said, here are some smart contract examples:

  • Reduction of expensive mistakes in trade finance: virtual contracts can minimize costly human blunders because they automate workflows and sharpen computation.
  • Tracking property information in real estate: In the real estate industry, smart contracts are used to capture property ownership details. Furthermore, they speed up the transaction rate and eliminate the need for attorneys. With these forms of contracts, it’s easy to manage the titling process.
  • Healthcare: the smart contract in the medical field can be used to protect sensitive medical information. Lately, medical data has been a target for cybercriminals. With smart contracts, this headache will be a thing of the past.
  • Boosting the convenience and integrity of polls: What is a smart contract within the electoral system? A decentralized ledger voting system holds the future of elections. By boosting the convenience of voting and availing it through virtual means, the blockchain voting technique will broaden accessibility and enhance high voter turnout. Digital agreements would verify voters’ identities to block casting votes many times.
  • Reduction of claims forgery in the insurance field: Players in the insurance sector keep grappling with this question: ‘What is a smart contract’? Much money is lost in the insurance industry through fake claims. Smart contracts will reduce the loopholes in claim processing. The insurance industry will save vast sums of money lost through dubious claims by sealing these loopholes.

Smart contract platforms

While some businesses might want to build new blockchain platforms from scratch, using the existing smart contract platforms is advisable. The owners of these platforms value their services based on the amount of energy required to execute the digital contracts. Here are the most famous smart contract platforms:


One cannot answer ‘what is a smart contract’ without mentioning Ethereum. This is the first digital contract platform popular among developers. The venue was launched in 2015 and supported the deployment of multiple applications, such as ICOs and virtual-agreement-based insurance. Ethereum’s smart contract has numerous perks, such as high safety, uniformity, and support. Ethereum is the most popular nft smart contract platform.


Ethereum co-creator Gavin Wood conceived this platform. It’s more of a decentralized ledger where multiple outlets are linked to each other. Its central element is the Relay Chain, which is associated with platform interoperability of parachains and parathreads. Parachains are popular to many developers as they allow them to create different blockchains with unique governance frameworks and coins.

Hyperledger Fabric

What is a smart contract within the context of data protection laws? Hyperledger exists to respond to this question. Linux Foundation developed the platform in 2015. It’s a permissioned network, requiring authentication and user identity. Hyperledger Fabric is suitable for enterprises that handle sensitive information and demand compliance with information protection regulations.


It’s an open-source network that addresses the main hurdles in the way of decentralized ledger adoption for assets and apps. The platform is supported by a worldwide society of validators, creators, and researchers. One of the advantages of using Tezos is that it uses Proof of Stake (PoS) instead of Proof of Work (PoW) to attain a a consensus. So, unlike miners who apply vast amounts of power to create a new block, Tezos uses delegates. The platform’s smart contracts are safer due to its support of formal checking. Also, before deployment, each virtual contract undergoes thorough auditing. Tezo’s smart contracts are valuable for fields that require high levels of accuracy, such as aeronautics and healthcare.


This platform was founded by McCaleb in 2014. It’s applicable when creating simple smart contracts for purposes, such as ICOs and escrows. Stellar is an exceptional platform for money exchanges. The platform beats all others in terms of superior speed, cost-effectiveness, and secure transactions.

Stellar lacks its own programming language for smart contracts development. Also, it doesn’t have a virtual machine to run its code. Thus, platform’s virtual agreement can be written using different programming languages.

The platform’s virtual agreements are linked and executed via multiple constraints, such as multiple-signature and batching. Organizations that require simple and effective smart contract platforms can use Stellar.


Whether you need to build smart contract crypto or nft smart contract, Solana platform is one of the choices available. Software engineers from Intel, Dropbox, and Qualcomm developed Solana in 2017. Its key objective is to overcome scalability issues associated with different platforms. With its 65,000 transactions per second, Solana has high speed which other platforms lack. A key feature enabling the high throughput is the Proof of History (PoH) consensus mechanism. This means that transactions through the forum aren’t lumped into blocks. Instead, each settlement lives inside its own league, becoming an input for the following payment.


Now you know ‘What is a smart contract’. The contracts have become essential due to multiple advantages, leading ones being cost reduction, high transaction speed, and elimination of third-parties. Multiple smart contract platforms exist where to develop and deploy these agreements. Some of them include Solana, Ethereum, Stellar, and Hyperledger Fabric. If you’ve been wondering what are smart contracts, our explanation above has helped you.
