Ethereum Ideology: What Exactly is Ethereum and How Does It Work?

Even though cryptocurrencies are still catching on slowly, they have been around for quite a long time. For more than a decade, these digital currencies have been used for various kinds of financial transactions and are still being used.

There are different types of cryptocurrencies in the blockchain market, all with different values, made by very different firms and run on different frameworks. Typically, they all run on blockchain technology but the two largest assets in the market which are Bitcoin and Ether, run on their own different chains.

However, it’s important to note that just like cryptocurrency is just one use of blockchain technology, Ethereum is more than just a cryptocurrency.

What is Ethereum?

Ethereum is a major distributed and public blockchain network. The Ethereum blockchain allows decentralized applications (dApps) to be built on it and primarily focuses on running code for these apps. The token used within the Ethereum network is known as Ether and its creation process is a bit different from that of Bitcoin.

The Ethereum blockchain is also different because it gives developers the freewill to do pretty much anything they want because even though most blockchains are considerably limited, the Ethereum chain isn’t. This means that developers can go above and beyond, building a gazillion and one apps as they see fit.

A Short History

Publicly, the Ethereum journey began in November of 2013 when Russian–Canadian writer and programmer, Vitalik Buterin, first published the Ethereum whitepaper. About two months after that, the official development of the network was announced and the initial team included Vitalik Buterin, Charles Hoskinson, Anthony Di Iorio and Mihai Alisie. This began a process of development and also an ICO which ended in August 2014 and successfully raised $18.4 million.

Before Ethereum was developed, there were significant limitations to the usage of blockchain applications. A good example is the Bitcoin blockchain that was initially developed for Bitcoin to strictly be a peer-to-peer cryptocurrency. This was a huge problem for most developers at the time because there was a lot more that they wanted to do. The two options available, starting with the most tedious and less time-effective one was to find a way to develop and expand the Bitcoin network so it could accommodate a lot more. The other option was to create a whole new blockchain that will be a lot less limited than its predecessors. This option was quickly picked up by Vitalik Buterin and the development for Ethereum began.

According to Buterin:

“I thought [they] weren’t approaching the problem in the right way. I thought they were going after individual applications; they were trying to kind of explicitly support each [use case] in a sort of Swiss Army knife protocol.”

The Ethereum Virtual Machine

This is a software built on the Ethereum network and which solved a lot of problems. Basically, EVM allows any developer to easily create any run any program they want, without having to worry about the programming language used. The EVM also simplified the process of creating applications and made it even more effective and efficient. So, there was no longer any need for a new blockchain to be built as this solution allowed as many development projects as possible, be built on the same network.

Mining on Ethereum

The process of producing Ether is a bit different from how Bitcoin is mined on the Bitcoin blockchain. On the Ethereum blockchain, miners do work to earn Ether instead of exactly mining for it. Ether, serves on its own, as a kind of fuel for the Ethereum network. Ether is also generally what is used by developers who create applications on the network a payment for charges and services.

Apart from Ether, there is another type of token that is used on the Ethereum network. This token is called Gas and it is used as payment for miners. When an Ether transaction is initiated, a gas fee is set along with it which is basically a fee paid to the miners so that they can include that particular transaction on that block, for the blockchain. The higher the gas set for an Ether transaction the faster the transaction is executed and then completed.

Uses of Ethereum

One major use of Ethereum is its ability to easily build decentralized applications. Shortened as dApps, these apps all serve different purposes but their decentralized nature means that they are not exactly controlled by any one individual, institution or entity. The decentralised nature of these apps help increase the amount of trust it garners because people know that because they are on the network and are public, they are not easily manipulated.

Another use is the creation of a Decentralized Autonomous Organization (DAO). These organizations are basically run by a programming code and built on the Ethereum network. Also their decentralized nature means there isn’t any one leader and so no one is in control. DAOs have tokens and these organisations are jointly owned by anyone who purchases these tokens.

Important Things to Note

  • Ethereum is more than just digital currency.
  • The Ethereum network allows developers create thousands of decentralized applications (dApps) on its platform.
  • Ethereum was created by Vitalin Buterik
  • The digital currency available on Ethereum is the Ether.
  • GAS is payment for miners who include transactions in a block for the blockchain.
  • Ethereum can also be used to create Decentralized Autonomous Organisations.

Bitcoin Ideology: What Exactly is Bitcoin and How Does It Work?

Over the years, many people have noticed that the idea of money, as we know it today, has quite a few inherent flaws. There are too many limitations to it and too many different governmental bodies all over the world controlling its creation, value and also regulating its usage and movement.

The average person has to jump through hoops of a million different shapes and sizes to successfully send funds across international borders. This is because of all the regulations that govern financial transactions either individually in a country, or internationally as a region. There has always been a great need to solve this problem to ease cross-border payments, whether they are for the business of personal. One major solution to this is cryptocurrency.

What is Bitcoin?

Bitcoin is the first decentralized cryptocurrency ever developed. It is a form of electronic cash or digital money that is completely deregulated without any sole administrator or central bank. Bitcoin can be sent directly from one user to another completely without any interference or required middlemen.

It was created sometime in 2009 by a person or a group of persons known as Satoshi Nakamoto. Even though the asset is about a decade old, the identity or identities of Satoshi is still unknown. A few people have come out with claims that they are the real Satoshi but most of their claims have been debunked.

What is a Blockchain?

Bitcoin (and all other cryptocurrencies) currently require a public, distributed ledger to function. This ledger is called a blockchain and records of all confirmed transactions can be found on a blockchain. Basically, every kind of Bitcoin transaction ever carried out is powered by the Bitcoin blockchain and is recorded, unalterable and irreversible. This presents a level of security that was hitherto unavailable with traditional transactions. The blockchain is a tightly run technology created with very strong cryptography.

Bitcoin Wallet

A Bitcoin wallet is simply a digital, virtual wallet that holds your bitcoin. All other cryptocurrencies also have wallets and these wallets are created specifically to hold the crypto. A Bitcoin wallet always has an address and this address is what is used to send or receive Bitcoin. A Bitcoin address is usually a long set of characters including numbers and letters and just as no two people can have the same traditional account number with a bank, no two Bitcoin wallets can have the exact same address.

Why Do You Need Bitcoin?

One of the most fantastic reasons for the use of Bitcoin or any other crypto is the level of autonomy it offers. The biggest problem with regular and traditional legal tender is how much trust is required for the system to run properly. This leaves it open, expensive and most of all, very prone to exploitation. Bitcoin easily solves this problem because not only can all transactions be verified, it’s impossible to make counterfeits on the blockchain due to its decentralization.

Other Advantages of Bitcoin include:

  • No Geographical Restrictions – Bitcoin can be used by anybody in any part of the world. Literally, anyone can have access to the blockchain.
  • Irrevocability – All transactions done via Bitcoin cannot be reversed. This means that the system cannot easily be manipulated. It also means, apart from the sense of security it gives to its participants, that proper caution is required before a transaction is initiated and completed.
  • Speed – Unlike traditional transactions, payments carried out via the Bitcoin network are completed in a matter of seconds. Because there are no intermediaries and no regulatory bodies, there really is nothing standing as a bottleneck and causing any kind of delay.
  • Perpetual Availability – Since it is not being controlled by any single person, authority or entity, there cannot be a general downtime throughout the entire blockchain. This means that Bitcoin is available 24 hours a day, 7 days a week, and 365 days a year.

Private Keys

As stated earlier, every Bitcoin transaction gets recorded in the blockchain. Because of the security requirements for the blockchain, every Bitcoin wallet must have a secret signature called a private key. This private key is used to sign each transaction as a way of showing precise proof that the transaction was actually originated from the wallet’s real owner.


Mining is a complex decentralized computational process that basically fulfils two needs.

  • Firstly, miners have to solve extremely difficult and complex mathematical problems on the Bitcoin network to produce Bitcoin. The Bitcoin produced when transactions are combined in a block and recorded on the blockchain is called a block reward.
  • Secondly, solving these problems authenticates each transaction thereby making the entire network a lot more trustworthy.

The process of mining, unlike before, can now only be done with very specific and powerful computers and there are millions of miners all over the world who are constantly doing this at any given point in time.

It’s very important to note here that only 21 million Bitcoins will ever be mined. The only solution for this is to change the protocol of the Bitcoin blockchain. This protocol was done to control how much Bitcoin is produced to keep it valuable but it is now thought that when that peak is reached, a lot of problems, especially with scaling, may now rear its head.

Important Things to Note

  • Bitcoin is a digital currency.
  • It is decentralized and so no one has complete authority over the network.
  • All transactions are recorded publicly and verifiable.
  • A Bitcoin wallet holds Bitcoin and is accessed through Bitcoin Wallet Addresses.
  • Private Keys ensure security on the Bitcoin Network
  • The network is available at any given time.

Until something about the Bitcoin protocol is hanged, mining of new coins will stop after 21 million Bitcoins have been mined.
