What is Ethereum: All You Need to Know Before Buying It in 2021

It’s 2021, cryptocurrencies are a rage and many people are buying them as a novel but a potentially exciting method of investment. Aside from Bitcoin, another popular name in the field is that of Ethereum. If you have come across it and are wondering “what is Ethereum, this post is just for you. This post will reveal to you all you require to think around one of the world’s most talked about digital currencies – Ethereum. Let’s get started. 

As we get started with this post about Ethereum, let’s give you a slight taster of what you will be able to read through this article. We’ll examine everything from what Ethereum is, as far as possible how to really buy it, and where to store your recently procured Ether coins. Some of the best places to buy Ether coins will incorporate Coinbase, Simplex and Binance. Capacity savvy, cold wallets are your smartest option – specifically, the Ledger Nano S and Trezor. More on that later. Let’s start with a bit of history first.

What is Ethereum: How it All Began

In 2012, a 17 year old Vitalik Buterin was acquainted with Bitcoin by his dad and turned out to be exceptionally inspired by its innovation. Vitalik started sending articles for Bitcoin Magazine and proposed enhancements to the Bitcoin stage. At the point when these upgrades weren’t made, he went ahead and decided to come up with his own cryptocurrency.

His thought was Ethereum, and it went live in 2015. Since it began, Ethereum’s cost has gone up a ton and it currently has a ‘market cap’ of $44.7bn (that is the all out estimation of all Ethereum cash on the planet today). Things being what they are, what is propelling this upward growth of Ethereum? Ethereum innovation can possibly change the world. If you are wondering about the technology that drives Ethereum, we will get to it right now.

What is Ethereum: How does it work?

It’s simpler to reply, “what is Ethereum?” when the first question is, “what is Ethereum attempting to supplant?” Let’s see a model: 

Alexandra composes instructional exercises utilizing Google Docs. She can alter her work and offer it to whoever she needs. One day Google Docs is hacked, or the public authority boycotts it, so Alexandra loses all her work. 

Presently Alexandra concludes that she will just utilize the word processor on her PC, so her work will be protected. In any case, it isn’t protected, right? Alexandra’s PC can be lost, broken, or hacked into. 

Alexandra is frantic now, so she chooses to sell her PC and purchase a pencil, a scratch pad, and a few stamps all things being equal. Task finished! 

Alexandra’s concern here is that she needs the accommodation and speed of the web, yet with the control and security of her pencil and paper. Be that as it may, what is Ethereum going to do about it? 

Ethereum offers an approach to utilize the force of the web without trusting applications like Facebook, Google, or some other online manager for the account with your own data. 

Applications like Facebook and Google gather and store the data of their huge number of clients within their massive servers. This implies that client information is kept in a few areas (this is called centralization). On the off chance that one of these areas is hacked into, we’re all in some hot water.

What is Ethereum Classic?

Ethereum Classic runs smart contracts through an open-source, decentralized, blockchain-based distributed cryptocurrency platform. Ethereum Classic was created after the network was hacked in 2016. The original Ethereum blockchain was divided into two parts: Ethereum Classic being the original and Ethereum being the newer blockchain.

Smart contracts are based on the principle of “Code is Law,” and work as self executing autonomous digital applications. Smart contracts can run based on their programming and don’t need external control. Some of the popular applications of this kind are automatic teller machines (ATM) and the Bitcoin system.

Ethereum Classic helps run smart contracts through decentralized governance. In other words, the contracts can be enforced without the requirement of a third party. Smart contracts are similar to if-then statements. What that means is that if a certain set of actions required within the contract get fulfilled, the parameters of the contract will be completed and the contract will be paid out. In case the parameters are not met, then there might be a penalty, a fee, or the contract might be voided, based on the terms that were established when the contract was written.

How Ethereum functions is by eliminating the need to confide in bunches of apps with private data. It accomplishes this by decentralizing utilizing ‘blockchain’ innovation. 

What does Blockchain mean?

Ethereum’s rendition of the web is one where a framework of systems called nodes replaces the usual servers and cloud. These hubs do the job of storing a common data set called a blockchain. 

There are a great many nodes in the organization, all putting away the whole blockchain. The more nodes there are, the more secure the organization and its information become. The data that is punched into this record needs your exclusive control. It isn’t put away on your PC, or in some kind of dedicated central server. Instead, it’s stored across the entire nodal network.

The data contained in the blockchain is checked by something known as the ‘consensus’. This implies that the greater part of the nodes should concur that data is right before it is permitted onto the blockchain. 

Hacking this sort of framework is close to being an unattainable goal, as you would have to control the greater part of the nodal network to force a consensus. Regardless of whether you controlled a large chunk of the nodal network, completing the attack will siphon off so much  money that it wouldn’t be worth it in the end.

As we discussed in Ethereum’s history, it didn’t imagine the blockchain innovation, Bitcoin did, however it is utilizing and improving it in some inconceivable manners. Now, let’s find out more about something known as the Ethereum blockchain.

What is Ethereum Blockchain (Blockchain 2.0)?

The Ethereum blockchain (or ‘Blockchain 2.0) utilizes comparable innovation to Bitcoin, yet it is further developed. It can do significantly more than the Bitcoin blockchain. It does this in two primary manners. 

Smart Contracts 

The Ethereum blockchain is planned in such a way that exchanges can possibly occur when certain conditions are met. The standards choosing these conditions are termed ‘smart contracts’. It’s a fundamental piece of the “what is Ethereum” question. 

For instance, envision a candy machine. On the off chance that a boy needs a sweet treat from a candy machine, he needs sufficient cash to pay for it. In the event that he needs more cash, he will not get his sweet treat. A brilliant agreement for this exchange may resemble this: 

Assuming the boy puts $1 in the candy machine, the candy machine will give him a sweet treat. 

When one of these contracts is composed, it can’t be changed. That is the reason they are termed ‘trustless’ transactions. You don’t have to confide in people in the organization — on the off chance that the states of the agreement aren’t met, it will not occur. 


Decentralized applications (or ‘dApps’) are just applications that don’t run on a usual central server. All things considered, they run on a blockchain — utilizing it to decentralize the server system. 

dApps are at the center of Ethereum’s structure and its convictions. The people who founded Ethereum need clients to learn Ethereum and expand on it. So another integral piece of “what is the Ethereum question” is unquestionably dApps.

Ethereum has its own coding language called Solidity. This coding language is used for constructing dApps. Since Solidity resembles JavaScript (quite possibly the most widely recognized programming language in the world), it urges designers to make new and energizing dApps. 

These dApps could before long be contending with (or supplanting) centralized applications, in enterprises like web-based media, web based business, email, and web based banking. There are unlimited opportunities for building dApps on Ethereum’s blockchain. 

How Does Ethereum Work? 

Ether is the cash of Ethereum. In some cases, the two are used interchangeably however it’s easier in the event that you attempt to recall that Ethereum is the framework and Ether is its currency. 

On the off chance that you need to complete anything on the framework, you’ll need some Ether. Ether energizes the Ethereum framework, and it’s frequently alluded to as ‘gas’ because of this. Every exchange on Ethereum needs a specific measure of ‘gas’ to take care of business. The greater the work, the more gas you need. 

The subject of what is Ethereum and how can it work is frequently joined by the Ethereum VS Bitcoin question. As individuals regularly contrast Ether with Bitcoin, so we’ll pause for a minute to clarify the principle contrasts. 

Bitcoin vs Ether


Bitcoin is a popular kind of digital money. Its blockchain permits manual distributed exchanges of computerized cash/digital money. In the event that Nancy needs to pay Ann 10BTC (Bitcoin) to paint her home, without utilizing a bank, she can utilize Bitcoin. It would appear in this manner: Nancy sends 10BTC (Bitcoin) to Ann. 

There is a cap on the total number of Bitcoin that can exist (21 million), so it could turn into a solid store of significant worth, similar to gold, silver or precious stones. 

The normal time for an affirmed Bitcoin exchange can be as brisk as 10 minutes.


Returning to what is Ethereum and its money: Ether serves as the digital fuel for the execution of the smart contracts within the Ethereum network. In the event that Nancy needs to pay Ann 10ETH to paint her home, she can utilize an Ethereum smart contract. The exchange would resemble this; IF Ann paints Nancy’s home THEN 10 ETH will be shipped off to Ann. In this way, as should be obvious, Ether can be utilized in a similar manner to Bitcoin. The lone distinction is that with Ethereum, Nancy will not compensate Ann until she has painted Nancy’s home. Ann will not get paid on the off chance that she doesn’t paint Nancy’s home, so she can’t swindle money. This equivalent framework can be utilized to manage exchanges, everything being equal, from messages to how an organization pays its staff. 

Unlike Bitcoin, there is no upper limit on how much Ether can exist. Albeit, the measure of Ether presumably will not go over 100,000,000 for an extremely, long time. 

The Ethereum exchange time is fast — Ether-powered smart exchanges simply require seconds to complete.

How to mine Ethereum?

In both Bitcoin and Ethereum, new money (Bitcoin or Ether) is made by an interaction called ‘mining’. Nodes on a blockchain need to verify all transactions; once that’s done, they get rewarded with new currency. For instance, an Ethereum node called a miner is remunerated with another Ether. 

This is called mining since it is like gold or precious stone mining. Rather than delving in the ground, however, the miners are literally mining through transactions, verifying them in the process.

Mining Ether in this manner is termed ‘Proof of-Work’ mining. It is called PoW (Proof-of-Work) on the grounds that the node needs to show that it has done the ‘work’ (confirmed the exchanges) to get its Ether reward. The terrible thing about PoW mining is that it utilizes a great deal of processing power and a whole lot of electricity, making it costly and awful for the planet. Hopefully, that cleared up the concept of Ethereum mining for you. 

Before long, Ethereum engineers are planning to switch to an alternative technique, called PoS (Proof-of-Stake). This strategy utilizes substantially less power, so it’s much better for energy costs and the planet! 

In PoS, clients with a great deal of Ether are chosen to check transactions (at random). This type of mining will be remunerated with expenses instead of another money and will consume much less electricity.

How to store Ethereum? 

Ether doesn’t leave the Ethereum blockchain, so it isn’t truly put away at a different place. In the event that you need to utilize Ethereum, you’ll need a ‘wallet’ (in some cases called an Ethereum ‘address’). 

Your Ethereum wallet will not contain any Ether, however it will contain the codes required to get to it. These codes are called private keys. On the off chance that you lose your private keys, you lose your Ether. So picking a decent wallet is vital! There are four primary kinds of wallets accessible to Ethereum users:

Hardware wallets 

These are physical devices such as USB sticks. The Ledger Nano S is one of the more-costly hardware wallets, and it offers safe disconnected key stockpiling. While that might sound convenient and safe, just remember that like a key, it can also get lost. Thus, be cautious where you put it.

Desktop Wallets 

Store your public and private keys straightaway on your PC. This choice requires you to have a password that you must remember. It likewise occupies a great deal of storage space. Exodus is a good option among these wallets.

Mobile Wallets 

These are similar to desktop wallets, but require far lesser space. They are ideal for putting away your public and private keys on your cell phone. Jaxx offers its clients key stockpiling for up to 13 distinctive cryptocurrencies, so you are spoilt for choice. 

Web Wallets 

Store your private keys on the web —like with the Coinbase wallet. As far as security goes, these are by far the most unsafe. So don’t store any Ether that you can’t afford to lose on these wallets.

Paper Wallets 

These are the most antiquated stockpiling choice — they are simply bits of paper with your access codes printed on them. They can’t be hacked, but they can fly away, burn, get torn or have water spilled on them. Even worse, you might forget where you put these paper wallets. So use them with utmost care.

If an Enthereum wallet is associated with the web, it is called ‘hot storage. On the off chance that it isn’t associated with the web, it’s called ‘cold storage. While putting away private keys, it’s suggested that you utilize a blend of both hot and cold wallets for the top most level security. 

How to Buy Ethereum? 

You can purchase Ether from three principal sources: 


These are coin trades like Coinbase which purchase and sell Ether for a charge. They are easy to utilize yet may frequently be to some degree costly. You can utilize them to purchase Ether with your fiat cash (USD, EUR, and so on)/credit/debit cards/online bank transfer.

Trading Platforms 

These platforms such as interface the purchaser and the vendor in return by utilizing a middleman (Cex). This is the thing that dealers use to exchange one kind of cryptocurrency with another. For instance, purchasing Ether with Bitcoin, or selling NEO for Litecoin. 

Peer-to-Peer Platforms

These platforms such as LocalEthereum permit purchasers and dealers to get in touch with one another straightforwardly to negotiate costs. This choice is less secure than the other two as you are exchanging straightforwardly with somebody you don’t really know very well. However, the absence of a middle man means that you don’t need to pay any transaction charges, and you can pay utilizing hard cash as well. 

Another incredible choice would buy Ether coins through Simplex – a fintech organization pointed toward furnishing you with complete exchange security and smoothness. Here, you’d have the option to purchase Ether with credit/debit cards as well.

What is happening with Ethereum now? 

A great deal of dApps are being made on Ethereum’s blockchain and they are being funded by a kind of fundraiser called ICO.

What are Initial Coin Offerings (ICOs)? 

These permit designers to offer the idea of their product on sale to pay for its creation. Think of it as a Kickstarter for dApps. 

Here are some of the dApps being created (or that have effectively been created) on Ethereum with ICOs: 

Golem is a dApp which permits clients to lease the inactive computing and processing capability of their PCs to one another. It resembles having the option to lease your vehicle to different drivers when you’re not utilizing it.

EtherTweet is a platform for communication similar to popular social media apps except for the fact that it’s on the blockchain so there is no central authority for regulating it. Believe it or not, it’s a dApp adaptation of Twitter, and it is totally uncensored.

Etheroll is an online gambling club that utilizes Ethereum’s blockchain to make reasonable online dice games. Think of it as a blockchain casino.

What are some issues with Ethereum?

With so much good stuff going on, it’s easy to look past the problems with Ethereum, but there a few stark ones.

Some critics have deemed the platform to be extremely complicated for the average user.. This intricacy could imply that accomplished clients could possibly trick amateurs on the off chance that they needed to. Ethereum has been contrasted with DOS, since DOS needs Windows to make it easy to use. Thus, perhaps there will be something delivered later on that will make Ethereum easier to understand! 

What is the Future of Ethereum?

Envision every one of the various exchanges that happen in regular daily existence. Purchasing or selling a vehicle, leasing a loft, putting down a wager on the Super Bowl. They all include confiding in outsiders with your cash and your data. Ethereum settles this issue, which implies it has heaps of potential for what’s to come. 

Increasingly more genuine innovation is associated with the web each day — we consider it the ‘Internet of Things’ (IoT). Entryway locks, coolers, broilers, lights, boilers, and TVs are totally associated with the web and they all should be run securely and with clear guidelines. 

Presently, envision an existence where smart contracts and dApps consequently direct those exchanges and advances, while an impregnable record of that is stored online in perpetuity. That sounds very nice, doesn’t it? So go get yourself some Ethereum now.
