A Beginner’s Guide to Smart Contracts: What They Are and Why You Should Care

If you’ve been following the Bitcoin and blockchain space for a while, you’ve probably heard a lot about smart contracts. These are computer protocols that facilitate, verify, or enforce the negotiation or performance of an agreement without third parties. In this article, we’ll introduce what smart contracts are and why they’re so important.

What are Smart Contracts?

A smart contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without third parties. These transactions are trackable and irreversible.

Initially people were concerned about should you trade forex or crypto.  But nowadays, people are more inclined towards understanding smart contracts.

Smart contracts were first proposed by Nick Szabo in 1996 as a way to create “trustless” electronic relationships. He defined a smart contract as: “a set of promises, specified in digital form, including protocols within which the parties perform on these promises.”

Since then, the idea has been taken up by many developers and programmers looking for ways to make transactions more secure, efficient, and free from fraud.

How do they work?

Smart contracts are self-executing contracts. The terms of the agreement between buyer and seller are directly written into lines of code. The code and the agreements contained therein exist across a decentralized, peer-to-peer network and are not controlled by any single entity.

When a smart contract is created, it is stored on the blockchain, which is a public ledger of all transactions that have taken place on the network. The blockchain is distributed across the entire network, meaning that each node (computer connected to the network) has a copy of the blockchain. This ensures that there is no single point of failure and that the data is immutable (cannot be changed).

When someone wants to buy or sell something using a smart contract, they send a transaction to the network. This transaction is verified by nodes on the network and, if valid, is added to the blockchain. Once a transaction has been added to the blockchain, it cannot be altered or removed.

The key advantage of smart contracts is that they automate processes that would otherwise require third-party involvement (such as lawyers or banks). This not only makes transactions faster and more efficient but also reduces costs. Additionally, because smart contracts are stored on the blockchain, they are secure and transparent.

What do they look like?

Smart contracts are computer protocols that facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts were first proposed by Nick Szabo in 1996.

A smart contract is like a traditional contract in that it defines the terms of an agreement between two or more parties. However, a smart contract is also executable by computers, which makes it possible to automatically enforce the terms of the agreement.

Smart contracts are written in code and stored on a blockchain. When someone wants to enter into a smart contract, they send a transaction to the blockchain that includes the terms of the contract. If all the conditions of the contract are met, then the transaction is executed and the parties involved receive their respective outputs.

Smart contracts can be used for a wide range of applications, such as escrow services, voting systems, financial exchanges, crowdfunding platforms, and much more.

Why should I care about smart contracts?

When it comes to our finances, we usually don’t think twice about the various contracts we enter into daily. We might not even realise we’re doing it – signing up for a gym membership, taking out a loan, or buying insurance are all examples of entering into a contract.

A contract is simply an agreement between two or more parties and can be verbal or written. In the real world, contracts are used to enforce promises made by one party to another. If you don’t hold up your end of the bargain, there can be legal repercussions.

What smart contracts are and how they work

Now imagine if there was a way to create contracts that were enforced not by law, but by code. This is what smart contracts are – self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code.

There are many potential benefits of using smart contracts. For example, they can help to reduce fraud as well as the costs and time associated with traditional contracting processes. Smart contracts also have the potential to increase transparency and accountability, as all parties involved would have access to view and verify the contract details.

So why should you care about smart contracts? Ultimately, it comes down to whether you think they can offer advantages over traditional contracting methods. If you’re interested in exploring this new technology further, then check out our beginner’s guide to smart contracts!

How can I start creating my smart contracts?

If you’re interested in creating your smart contracts, there are a few things you should know before getting started. First and foremost, smart contracts are immutable, meaning they cannot be changed or deleted once they’ve been created. This is one of the key features that makes them so secure. To create a smart contract, you’ll need to use a programming language like Solidity.

Once you’ve written your smart contract code, you’ll need to deploy it to the Ethereum blockchain. This can be done using a variety of tools and services, but we recommend using Truffle for ease of use. Finally, once your smart contract is deployed, you’ll need to interact with it to trigger its execution. This can be done using Truffle’s console or another Ethereum wallet like MetaMask.

What is an Ethereum Wallet Address and How Do I Get One?

There are various platforms to buy cryptocurrency in India. You can use any of them to create an Ethereum wallet. An Ethereum wallet address is a long string of numbers and letters that are used to send and receive Ethereum. You can get an Ethereum wallet address by creating an account on an exchange or online wallet. Once you have an account, you will be able to generate a wallet address.


Hopefully, this guide has given you a better understanding of what smart contracts are, and how they work. While they may seem complicated at first, once you get the hang of them, they can be an extremely useful tool in a variety of different situations. If you’re not sure whether or not smart contracts are right for you, it never hurts to ask someone who is more experienced for their opinion.
