An Ultimate Guide to Smart Contracts

With numerous scams happening not only in this country but also in the whole world, blockchain has successfully gained popularity. Thanks to all the conferences taking place at the global level which have made us understand the importance of blockchain, its concepts, and its features. Though Blockchains have its own issues that need to be resolved but it also has several benefits. Among many, one is the concept of Smart Contracts.

Smart Contracts

It is one of the most utilized and successful applications of blockchain technology. The concept of smart contracts was first introduced by a computer scientist and a cryptographer named Nick Szabo in 1997 long before bitcoin was even introduced. However, it was 2013, when a 19-year-old programmer Vitalik Buterin integrated super contracts with blockchain technology and called it Ethereum. Later, this gained public attention due to its sundry of advantages.

What is a Smart Contract?

These contracts can help you in exchanging money, property, or anything having a value with high speed and transparencies while avoiding all the middleman and their fees. Basically, it is a crypto contract or a type of computer program which controls the transfer of digital currencies or assets between 2 parties after a certain set of agreements or conditions. It avoids any conflict which can arise in paper currencies.

In simple words, it is a complex computer protocol that facilitates, verifies, and enforces the terms of any contract between 2 or more parties without the involvement of any third party saving time as well as money. It has a set of rules which must be agreed by all the involved parties and if these are met then these contracts execute itself to produce the result.

With Smart Contracts, you can exchange anything including, money, shares, properties, and so on. Herein, all the transactions made are immutable i.e. cannot be changed, irreversible and fully trackable. Now different platforms like Ethereum, Bitcoin and Nxt uses the concept of smart contracts.

Now, Let’s Understand it by Couple of Real-World Scenarios

Scenario 1: Buying a Car

Buying a car
Buying a car

Let’s assume that you want to buy a car. You know that there are numerous steps and processes which need to get done. If you can’t pay all the money at once then probably, you’ll go for a loan or financing option that requires several background checks, filling different forms, and identity verification, right?

This might include several processes involving middleman’s commissions and fees. All these increases the duration as well as the amount for buying the car. It can be tedious for some and hectic for many.

Now imagine another case, where instead of going to all these middlemen, long verification processes, and background checks, you directly show all your details stored in a blockchain to the lenders and they can quickly make a decision whether to credit you the amount or not. Here, a smart contract comes to play which can be created for you, your bank, and a car dealer.

Once everyone gets assurity then your bank can release the payment to the car dealer and in return, you get the car from your dealer after meeting all the terms. All the process is automatic, transparent, and immutable which can be checked or tracked any time by any party.

Scenario 2: Renting an Apartment

Assume that the agreement of your current rented apartment is about to expire and you are looking for a shift. Generally, the process would involve going to the broker, paying the commission, paying for all the paperwork, NOC requiring the verification and other procedures. These all can take a lot of your time and money.

Now imagine a situation, where you can do all these through a blockchain by digitally making a payment to your next landlord in cryptocurrency without any involvement of a broker. Herein, you pay directly to the owner, he verifies all your details and arranges all the paperwork after which he or she gives you the digital entry key. If all the terms are agreed by both the parties, you’ll receive the digital key on time and he would get the money, or else you would get your refund immediately.

This type of smart contract work on the “If & Then” principle i.e. If the owner gives you the key then anyhow, he’ll receive the money and if he doesn’t give you the key then you get your refund. Neither you nor the owner can alter the documents or amount without coordinating with the other party, making it a faultless delivery system.
