This article will go over the basics of what a smart contract is, what they are most commonly used for, and how they work in the cryptocurrency world. Smart contracts help ensure that all parties involved have agreed to perform the terms of an agreement before anything gets executed. They are one of the main benefits that blockchain technology has brought to society because it does not require trust between parties when making transactions.
What is a Smart Contract?
A smart contract is an agreement that is created in code. This allows the terms of the contract to be executed automatically once the required conditions are met. While this technology has many potential applications, its main use in the blockchain space right now is for payments between two parties. Smart contracts are used when one party wants to pay another person without requiring trust in them or an escrow agent.
How are Smart Contracts Used?
Smart contracts are made to perform one or more actions. These actions can be simple, such as sending funds between two parties, or complex, such as creating a digital asset backed by real-world assets. For example, something like a real estate investment contract can automatically pay dividends based on the performance of the underlying asset. This transaction would be automatically executed once certain conditions were met and could not be stopped by either party.
The core idea behind smart contracts is that they execute the terms of an agreement without requiring trust between the parties involved. The execution happens when all of the necessary conditions of the agreement have been met and cannot be stopped or changed by any party involved.
Do I have to be a developer to make a smart contract?
Smart contracts are made using programming languages. They are not complicated to create, but you will need to have some expertise in the programming languages used in the smart contract creation process. If you feel that you have some knowledge of these programming languages or have had similar experience in the past, then you can likely find someone who is willing to pay for your help in creating a smart contract.
Where can I find smart contracts in the cryptocurrency space?
You will find smart contracts in all currencies that use a blockchain. These include: Ethereum, Ethereum Classic, Monero, and Litecoin. Anything that uses a blockchain and is traded on an exchange will have smart contracts in it because they are needed to complete transactions and enforce the terms of the contract. If you see a contract in the code of an altcoin or ICO token, it is likely created by someone else and not available for public use.
Ethereum was the first blockchain to mainstream the term "Smart Contract" as it became the second most popular crypto currency behind Bitcoin. Since then, the trend has been moving towards Ethereum as its platform is generally more friendly to developers. The number of contracts within Ethereum has increased every year and is showing no sign of slowing down.
However, gas fees (i.e. transaction fees) have been an issue for developers, so for this reason, a lot of them have started to code in a new language called "Solidity" that compiles into Ethereum Virtual Machine (EVM) bytecode. This language is what has made Ethereum contracts much more cost efficient and improved the speed of transactions. It will continue to grow in popularity as it can be used with any EVM compatible blockchain (i.e. Ethereum Classic, EOS).
Why is a Smart Contract Beneficial?
There are several benefits of smart contracts, but the most important is that they prevent fraud and theft. There were more than $1 billion in losses from scams on altcoin exchanges in 2017. A contract could have prevented many of these scams.
Smart contracts allow for more efficient transactions because they only execute the terms of the agreement when all parties involved agree to it.
What makes a smart contract smart?
A smart contract needs to be able to understand and execute the terms of an agreement. It also needs to be able to keep track of everything that happens during the lifetime of the contract and need to be able respond automatically when certain conditions are met. It must also contain all the common elements that are present in most contracts, such as:
● Parties involved in the terms of the agreement;
● The items being delivered; and,
● Payment amount.
Do I need a smart contract?
No. Smart contracts are not required to trade on an exchange, but they do make the process of executing transactions much simpler and faster. These transactions can be difficult to complete without smart contracts because there are many different actors involved who all must agree. You can read more about some of the issues that can arise during some types of complex transactions in this article, How the Blockchain solves trust issues in real-world business scenarios .
What are some examples of how smart contracts are used?
The most common use for smart contracts is to create a digital asset backed by real-world assets that pay dividends based on the performance of these underlying assets. By way of example, smart contracts may be used for creating legal agreements. If you need to create a contract in code where two parties must agree to the terms of the agreement before it is executed (or if there are other specific conditions that need to be met before the contract is executed), then this type of program can help ensure that these parties do not run into legal issues or other problems while completing the terms of the agreement.
For example, a smart contract could be used to create a legal agreement that says: I will pay you $___ for this asset if the value of your shares reach $___ within the next ___ days.
Conclusion
Smart contracts are a core part of blockchain technology that allows parties to complete a transaction or agreement without requiring trust between them. These programs contain the terms of the agreement and automatically execute once the correct conditions have been met. They can be used for simple transactions, such as sending funds from one person to another, or complex transactions, such as creating a digital asset backed by real-world assets.
Disclaimer:
Cryptocurrencies are highly speculative and risky investments. It is important to do your research before choosing any coins or tokens you want to invest in. Cryptocurrencies can still be a solid investment, but you should not expect huge returns in the short term.
This post is by no means meant to discourage anyone from investing in cryptocurrencies and blockchain technology. I am merely trying to convey that there are a lot of unknowns and high risks involved with this new technology. It may take years for cryptocurrencies to catch on, but there is also the possibility that they will never break into mainstream use at all.
I am not an expert in economics, trading, finances, or crypto trading and am not providing any advice.
