What Is a Smart Contract?

Smart contracts are quickly gaining popularity due to many people’s need to ensure that other parties comply with certain agreements. Each contract is made with a specific set of data that can’t be replicated, which also makes it very safe.

People started using smart contracts over 20 years ago. However, they have become famous due to the popularity of the Bitcoin industry. Now that so many businesses are interested in knowing more about it, they also want to find out about the contracts and other specific features.

Since contracts involve specific data within a network, they can be complicated to understand. They often include coding and processes related to programming. That’s strange for someone without development knowledge. Therefore, you might want to know more. Read on and find out everything you need to know.

What Is a Smart Contract?

A smart contract is a computer program. It executes, documents, or controls terms according to a contract or agreement.

The use of smart contracts is based on the idea of reducing intermediaries. Thus, transaction costs and different risks are also decreased.

Smart contracts are an essential element of different platforms and applications. It’s mainly used in distributed ledger and blockchain technology.

How Does It Work?

A smart contract is a specific term used to describe a computer code. The code has the responsibility to execute all terms of an agreement.

Smart contracts work similarly to a vending machine. The metaphor was first described by Nick Szabo, who mentioned that just like vending machines eliminate the need for a vendor, a contract can replace many industries’ intermediaries. They’re a more effective way to ensure that people comply with all the terms of an agreement.

Each smart contract uses logic parameters to function. Following the vending machine example, the item would work with a code that dispensed snacks each time a person inputs money and their snack choice. Similarly, smart contracts require specific parameters to complete their purpose.

It sounds straightforward, but developers are working to make contracts more complex. A smart contract also has to be completely objective at all times. In other words, each time “x” occurs, then “y” follows.

Consequently, code follows strict logic when a contract uses it. Smart contracts can, for example, move specific assets from one account to another when they both follow a series of parameters.

Considering that smart contracts are so effective, nowadays, more people use them to ensure each party is content with the agreement. The code can never execute the steps if the preliminary requirements of the transaction haven’t been met, which is why the contract execution solely depends on everyone complying with the terms and conditions.

Programming languages are used in those types of contracts. Smart contracts, then, differ from the traditional way to ensure that every party complies because it doesn’t rely on attorneys or similar processes. Additionally, smart contracts function without the need for many processes, which makes them very effective.

What Is the Smart Contract Code?

Each smart contract uses written code to secure that each party complies with the terms. In other words, the digital process happens due to a computer program code.

A smart contract cannot execute the desired results unless the program automatically detects that it’s meeting the conditions. Thus, using smart contracts allows all parties to enjoy transactions protected by various agreements they must follow.

Developers who work with smart contracts often address different issues so that they work. For example, they must create rules so that the automated program functions. If it doesn’t comply automatically once all parties do what they’re supposed to, it loses the essence of being a smart contract.

Besides being self-executing, a smart contract also requires a transaction payment. Although the payment is not very expensive, the chain needs it. That way, the contract is executed.

If the smart contract is complex, the payment is higher. That happens especially regarding the Ethereum blockchain, where payments are known as “gas.” Consequently, gas also works as a security measure to ensure that contracts are not overly complicated.

In the real world, people need more effective strategies and tools each day. Although traditional contracts could be convenient for many business people, smart contracts ensure a secure future since they cannot occur until people follow the rules.

Can You Enforce a Smart Contract?

Although smart contracts are known to be very secure, you technically can’t enforce them. A smart contract is not legally binding, which is why you can’t force someone to comply.

However, there are technical parameters that developers could add to the program’s specifications. If the code is well-written, then using the contract should allow you to get a precise amount of Ether when the rules dictate so. Even so, there are exceptions to that rule.

Suppose you encode a contract. The purpose is that it gives you a certain amount of digital assets on a regular basis. If the account owner does not have enough assets to pay you, the contract is rendered useless. Thus, two parties can agree on the contracts’ terms. Smart contracts, nonetheless, cannot oblige the other party to comply if they don’t have the technical ways of doing so.

What Is a Smart Contract in Blockchain?

Smart contracts are on the Ethereum blockchain. That means that each contract is at a specific address. In other words, it’s a type of Ethereum account.

Many people choose blockchain technology because it’s effective and reliable, often more than legal contracts. Besides, the blockchain network is a decentralized and automated platform. That’s why it’s very trustworthy. Any events can occur, but the program can still automatically process the transactions.

Business people are learning more about blockchain. Smart contracts are just a part of it. Additionally, keep in mind that a smart contract doesn’t necessarily have to be stored in Ethereum. Smart contracts can be in any blockchain, but Ethereum is the most common since it offers unlimited capabilities.

Since the contracts are in a decentralized platform, all payments must occur using cryptocurrency instead of money. Bitcoin is the most well-known example of cryptocurrency. However, in the case of a smart contract, another token used is called Ether.

Blockchain-based technology allows a higher level of security in all transactions as it eliminates the need for third parties and safely stores all sensitive data. Therefore, using blockchain (specifically Ethereum) works similarly to a virtual machine since it lets people make transactions, interchange a specific token, and rely on the technology to have insurance of the terms and conditions of an agreement.

Smart Contract Example

You can find many smart contracts online, even if you scroll through sites such as Ethereum. Smart contracts often involve a specific amount of digital assets. They are transferred to someone else once the parties meet the initial conditions.

A common model includes that the program first checks if the sender has enough assets. Then, it determines overflows and allowance. Finally, it subtracts Bitcoin from the sender and sends it to the other person. That way, all parties are content.

Are Smart Contracts Legal?

A smart contract does not constitute a legal agreement. Smart contracts are not regulated by the law but by blockchain technology, and their insurance bases on the security measures that the coding offers.

Although smart contracts aren’t legal, they only allow a specific set of outcomes. Therefore, the asset exchange that occurs could not happen if the blockchain doesn’t confirm that the first events occur.

Other people believe that the execution of smart contracts could lead to people complying with the terms of the agreement. In other words, the smart contract only allows the exchange of assets when the events follow the rules, which is why business people would want to comply with the terms to get the desired results.


The world is quickly changing. People and businesses want to adapt fast so they can take advantage of everything that technology offers. However, to seize each opportunity, you must know all you can on the subject, especially if it’s something you know nothing about.

Although smart contracts originated more than 20 years ago, they are very popular now. That makes them very convenient as you can use them to help your business. Nonetheless, you should know what they involve. That way, you can understand their perks and disadvantages.

For instance, you might not get what you want if you’re looking for a legally binding accord, as they’re not regulated by the law.

Smart contracts are stored in the Ethereum blockchain and they ensure that all parties agree with the execution of the terms of the agreement. Since the contracts are safely stored in an address, no one else but the people involved can access the network, which is why they’re also very convenient for business people.

A smart contract is certainly a way to not only store data in the blockchain, but also to rely on technology rather than intermediaries. Thus, people don’t need to worry about losing their data or assets since the contract doesn’t comply unless everyone is content.
