A smart contract is like a computer program that runs by itself and carries out the rules of an agreement without needing anyone else to oversee it. These contracts can do various things, like exchanging money, providing services, unlocking digital content, or even changing the owner’s name on a property document. They can also help protect your privacy by allowing you to share private information only when someone asks for it in a specific way.
Smart contracts come in different types, mainly based on what they do. There are generally four types of smart contracts.
Payment Contracts: These contracts help transfer money between parties according to set conditions. They make sure that funds are sent only when specific requirements are fulfilled. For example, you could use a payment contract to send money to a seller only after the buyer gets the products or services they paid for.
Escrow Contracts: Escrow contracts act like intermediaries in transactions, holding onto money or assets until certain conditions are met. They make transactions safer by ensuring both sides do what they promised before releasing the funds or assets.
Governance Contracts: These are used for making decisions in a decentralized way within a blockchain network or organization. People who own tokens can vote on proposals or changes to the rules of the network. This helps keep things fair and open.
Multi-signature Contracts: These require approval or signatures from multiple parties before a transaction occurs. They add extra security and are helpful when several parties must agree on something before it goes through.
Application of Smart Contracts in Various Industries
Smart contracts run on blockchain technology. Hence, we can build decentralized and transparent systems to change how we learn and certify our accomplishments.
Education Using Smart Contracts
In education, smart contracts have the potential to simplify administrative tasks, boost security, and create unchangeable records of accomplishments. Let’s look at how smart contracts can benefit education with an example called “CourseContract.” This innovative smart contract is designed to simplify course enrollment, payments, exams, and certification. CourseContract uses the Ethereum blockchain and includes features that improve the learning process.
CourseContract simplifies course enrollment for students. They can sign up for courses using the contract’s “enroll” feature, which checks if they meet the requirements and starts the payment process. This contract accepts payments in a cryptocurrency called “Coinismus,” which students can easily manage in their Coinmask wallet.
Once students are enrolled, they can access the course materials and start their studies. When they finish the course, they can take the final exam. To begin the exam, students use the contract’s “take exam” function, which marks that they’ve taken it.
CourseContract offers a chance to retake the course if a student fails to pass the exam. Students who want to retake it can use the contract’s “repeatCourse” function. This function gives them a 50% refund of the initial course fee back to their Coinmask wallet, so they can use it again to pay for the course.
Smart Contracts in Finance
Smart contracts allow financial institutions to turn physical assets like gold, diamonds, and other valuable materials into digital tokens. This means that people can invest in these assets without physically storing them. When we tokenize physical items using blockchain technology, it can lead to lower transaction fees, quicker trade processing, and safer peer-to-peer transactions.
Banks are centralized institutions that offer loans and hold money for people and businesses. Smart contracts, on the other hand, provide a decentralized way to do similar tasks. For instance, they enable peer-to-peer lending, removing the need for intermediaries. Unlike traditional paper-based processes, these transactions occur quickly, enabling flash loans to be borrowed and repaid within seconds.
Smart contracts offer cost-effective and faster payouts in the insurance industry, but they may only suit some policies. They are most effective for policies with clear, simple “if/and” conditions, such as travel insurance. For example, these automated contracts can swiftly provide a predetermined amount to policyholders if their flight is canceled or delayed.
Smart Contracts in Real Estate
A smart contract, stemming from the advancement of blockchain technology, has become a hot topic in the property tech industry. It’s now the preferred choice for real estate businesses seeking transparency and security in their agreements, benefiting everyone involved in a contract.
Real estate transactions can be costly, with closing fees sometimes reaching a significant amount due to the involvement of many intermediaries like lawyers and brokers.
Blockchain and smart contracts reduce the need for many individuals to participate in the process, which can lead to cost savings.
Investing in real estate can be challenging because buying property is often very expensive, making it unrealistic for many. Additionally, the complex and lengthy processes involved can deter people.
Blockchain technology provides alternatives. For instance, projects like Parcl empower you to customize your exposure to real estate in your preferred locations. You can achieve this through synthetic assets and smart contracts.
With this approach, you can invest in your preferred neighborhoods without owning physical real estate and have flexibility in deciding your initial investment amount.
Smart contract development happens when all parties agree to the contract’s conditions, which it activates at a specified point.
Once parties execute and use smart contracts, no one can change or tamper with them because they securely store them on the blockchain.
Thanks to the blockchain’s immutability and transparency, any data stored within it remains unaltered and secure, ensuring the reliability of smart contracts. This transparency means every transaction is visible and accessible on the blockchain, further enhancing trustworthiness.
Advantages of smart contract
Transparency
Transparency is a key feature. All parties involved have access to the same information simultaneously, reducing the chances of anyone manipulating the contract’s terms. Because smart contracts rely on blockchain, they guarantee that no one can alter the data. This enables contracts to be created without mutual trust, preventing potential breaches or errors in managing and executing contracts.
This transparency provides security and trust because all parties can access the contract’s data and information as long as the contract is active. Transactions are duplicated to create a record that all involved parties can reference.
Autonomy
Smart contracts operate without needing trusted third parties or human involvement, giving parties independence and control.
Cost Reduction
Cost reduction is linked to removing intermediaries. When parties don’t rely on a third party to validate contract terms and provide trust, they eliminate costs associated with intermediaries, including their fees.
Speed
The absence of intermediaries reduces costs and speeds up the process. Smart contracts operate automatically, reducing the time needed compared to manually executed contracts involving third parties.
Automatic Updates
Smart contracts automatically adjust and update their terms thanks to their technological and self-executing nature. This eliminates the need for intermediaries and additional processes to handle updates.
