Ethereum removed this necessity, making it easy for developers to create decentralized applications dApps without having to create their own associated blockchain. Think of these as apps or apps, like the ones you have on your mobile phone, but which are built on Ethereum's blockchain.
Read on and we will explain more about this. The majority of all decentralized applications, cryptocurrencies and NFTs that exist today log data and transactions on Ethereum's blockchain. For many, Ethereum is also seen as a good investment object, both because the cryptocurrency Ether has increased in value over time, but also because the currency Ether is needed to be able to interact with cryptocurrencies based on the Ethereum blockchain.
ETH thus becomes the "oil" or "currency" that makes this network work. Ethereum which is referred to as "Ether" or "ETH" when it comes to the cryptocurrency, and "Ethereum" when it comes to the network or protocol. However, it is common for people to also use the term Ethereum even when talking about the cryptocurrency. The term for the smallest unit of Ethereum is defined as a gwei. This allows very small transactions that traditional money can not perform.
Transaction costs on the Ethereum network are often measured in gwei. Because Ethereum is a divisible cryptocurrency, it is not uncommon to own, for example, 0. This is something that separates crypto from shares, that one must own an entire share. In crypto, you can easily own 0. Together with Bitcoin, Ethereum is the standard against which all other cryptocurrencies are measured.
Many developers choose to create Ethereum-based applications because of their network's long-term security and stability. Ethereum has its own programming language, Solidity, which makes it easy to create Ethereum-based decentralized applications. Ethererum based applications are created through so-called smart contracts. A smart contract is, in short, a contract agreement between two parties which is stored in a blockchain, and which can be performed without trust without the involvement of a key player.
It is thus a computer program that is governed by a set of rules the contract. Ethereum enabled developers to create decentralized applications through smart contracts on the Ethereum blockchain. The majority of all applications and cryptocurrencies that exist in crypto today are built on Ethereum's framework.
Like Bitcoin, Ethereum's cryptocurrency is decentralized, and Ethereum can be sent and received without the involvement of a key player. Firi explains: What is a blockchain? A blockchain is simply explained as a database that contains data, and which is secured through a distributed network of participants.
A database is a collection of information. This data is stored in blocks, and each block of data is linked together and forms a chain - that is, a block chain. The most common data in a blockchain is transactions. Instead of a key player being responsible for storing the data, the majority of blockchains are secured using cryptography and through a decentralized network of people around the world.
An important factor that distinguishes blockchains from regular databases is that the information in a blockchain cannot be manipulated or changed. Who created Ethereum and what is the story behind it? Ethereum was first conceptualized through a so-called white paper a research document , published entitled "A Next-Generation Smart Contract and Decentralized Application Platform" by the year-old Russian-Canadian Vitalik Buterin in Vitalik, which was quickly declared a genius by many within the crypto community, was able to quickly assemble a team of talented developers and crypto-enthusiasts.
In late , Vitalik Buterin shared his vision and goal of building decentralized applications. At the time, he worked for Bitcoin magazine and wrote articles about Bitcoin. His argument to several developers in the Bitcoin community was that blockchain technology could be used for other applications in addition to creating digital currencies. Vitalik also confirmed that he believed there was a need to create a more robust programming language that enabled blockchains to be linked to traditional assets, such as stocks and real estate, and that could support all possible transactions.
After presenting Ethereum at a Bitcoin conference in , Vitalik Buterin ended up collaborating with a number of what would become future co-founders to build on Ethereum's vision, infrastructure and technology. A key figure who was instrumental in building Ethereum's technology was Gavin Wood, who created the software that enabled developers to build decentralized applications on Ethereum.
So what is an "Initial coin offering ICO "? Well, it's a term that was borrowed from traditional finance where one talks about "Initial Public Offering IPO " where new company shares are being offered to the public. In a similar way, a solution was found in crypto where investors were given the opportunity to buy into the cryptocurrency ETH.
However, it is important not to compare ETH with a stock, as there are some significant differences. On July 30, , the Ethereum network went live. Summary Ethereum was conceptualized by Vitalik Buterin in , who together with 7 others created the Ethereum protocol. Gavin Wood founder of Polkadot and Kusama played a major role in developing Ethereum's technical framework in Several of Ethereum's founders have since created other well-known protocols, including Cardano and Polkadot. How does Ethereum work?
Like Bitcoin, Ethereum is a solution based on blockchain technology. A blockchain is, in short, a log of transactions and data secured by an open, global, decentralized network using computing power. Similar to Bitcoin's blockchain, where you can send and receive bitcoins, Ethereum's blockchain is used to send and receive Ether globally, without a third party being able to see or enter unexpectedly.
Where Bitcoin was developed for the purpose of being a digital currency, Ethereum was created as a more flexible blockchain that makes it easy for developers to build decentralized applications, also known as dApps on top of the Ethereum blockchain. New Ether comes into circulation in the form of rewards to miners who secure the Ethereum network. There are today approx.
This flexibility is due to the fact that Ethereum makes it easy for developers to publish software on Ethereum's blockchain through smart contracts. Software that in practice is significantly more complex than what Bitcoin's blockchain can handle.
A smart contract is simply explained a contract agreement between two parties that is stored in a blockchain. The contract is written with a data code. Smart contracts on Ethereum make it possible to automate the implementation of an agreement or contract without the involvement of a third party or to need trust in the other player with whom you have a contract. Smart contracts are based on "if, then" logic, so if X action is performed, then Y action is performed. With smart contracts, you can be sure that the outcome of what has been agreed will be implemented through the blockchain automatically, without the risk of downtime, fraud, censorship and involvement from third parties.
Other cryptocurrencies are being built on Ethereum. If you visit coingecko. As we have talked about above, Ethereum has made it possible for other developers to build their own apps on Ethereum's blockchain. This gives them access to the network's security and size, and they do not have to build everything themselves from scratch.
They use Etherum as infrastructure and framework for their own project. We can try to draw a comparison to traditional IT. Imagine how Microsoft has created an operating system that provides a platform for other software developers to build things on.
Microsoft "is at the bottom", while other software companies can in turn build new programs based on, and work with the standards in Microsoft's system. For example, you make a computer game for Microsoft, a video editing program, or you "host" your website with Microsoft's services. These other programs have their own companies, but they are built with Microsoft as a framework. The existence of an ecosystem of programs based on Microsoft, in turn, contributes to Microsoft becoming very valuable.
Similarly, other crypto projects can build on Ethereum, and they may in turn have their own cryptocurrency that has a function in their system. Ethereum has developed a technical standard for such cryptocurrencies, and these are called "ERC tokens". These cryptocurrencies are intended to have a practical function in the project to which they belong, such as voting rights, the right to payments, rewards, security and more.
However, not all ERC tokens will have any function beyond being an instrument for speculating in price. It is relatively easy for a person with the right technical skills to launch such a cryptocurrency, so be careful what you invest in if you are going to buy such "tokens". This means that if you are going to buy an NFT, this is most likely also stored on the Ethereum blockchain.
Summary: Ethereum is an open, global and decentralized network based on blockchain technology. In this blockchain, all information and transactions are stored on the network, and no central unit alone can control or manipulate this. Ethereum offers a network and infrastructure on which other developers can build their own projects. These are apps that are based on Ethereum and use "smart contracts" to automate various functions and services.
These projects again have the ability to create their own cryptocurrencies on the Ethereum blockchain. How is Ethereum's blockchain secured? Ethereum Virtual Machine EVM is used to store all information about transactions, accounts and smart contracts that exist in Ethereum's blockchain. The information stored in Ethereum Virtual Machine is verified through a decentralized global network of participants who use their computers to ensure that all information is accurate at all times.
These participants are either known as nodes or miners. A node stores a copy of all data in the Ethereum blockchain, and comes to a common agreement with other nodes that the information is correct using that data power and power. A miner secures the blockchain using computing power and power, but unlike nodes, miners do not store a copy of the blockchain. This way of securing a blockchain is called Proof of Work, and was first introduced through Bitcoin.
Ethereum primarily uses Proof of Work to secure its blockchain. The computers that nodes and miners have to set up are referred to as a mining rigs. It is these computers that perform the registration and storage of new transactions in the blockchain. In practice, these computers are used to solve a cryptographic math problem for each new block extracted in the Ethereum blockchain. This is how Ethereum is structured, and for each new block there is a new math problem that must be solved by the mining rig.
It solves the problem with its mining rig first, can receive a prize in the form of ether. In practice, this means that Ethereum's blockchain is secured through the use of incentives. People can earn ether ETH by securing the network and by using computing power and power. In addition to receiving prizes in the form of Ether from the network itself, nodes and miners also receive additional prizes in the form of transaction fees paid by people who use the Ethereum network. Migrating to Proof of Stake In September , Ethereum made the transition to a so-called "Proof of Stake" system instead of using mining.
Thus, the "mining" of Ethereum is now over. You can read more about this later in this article. Summary: There are "nodes" and "miners" who together secure the network by coming to an agreement that the information is trustworthy. Ethereum today uses a system called "proof of work" and is based on the same mining system that Bitcoin uses. Miners or "miners" are paid in Ethereum to secure the network by using electricity and computing power. In addition, they get paid in transaction fees when others use the Ethereum network.
Ethereum has in September replaced this "proof-of-work" model with another model that does not require so-called "mining". The new model is called "proof-of-stake" and will not require as much computing power and electricity as "mining". We will return to this later in the article. How does Ethereum work for users? Ethereum is an open protocol.
Anyone can use the network to send, receive and store ether. In practice, this is done by creating a decentralized Ethereum wallet, and by using digital signatures. In order to participate and interact with the Ethereum network and applications built on Ethereum as a user, you must pay for those who secure the network to verify the transactions you perform. This payment is made in the form of Ether and the transaction fees paid are defined as "gas" just like needing gas for the car.
Because the majority of all decentralized applications are smart contracts built on Ethereum, this means that you need to have Ether in your digital wallet if you are to use most of the services that exist in the crypto world today. How much you have to pay in "gas" depends on how much traffic there is on the Ethereum network. Increased traffic means higher competition to have their transactions verified on the blockchain, which results in more expensive fees. In recent times, the number of applications based on Ethereum's blockchain has increased significantly, which has also resulted in sky-high prices for transaction fees because the network is congested.
In a way, it can be said that Ethereum has had scaling problems as a result of its own success. One of the most important challenges that one is working to solve is namely to have both fast and cheap transactions on the network at the same time as it is decentralized and ensures top security.

Portable — Again, a party must be able to move a currency around for it to have any use. Scarce — Finally, a currency must have a limited supply to prevent inflation. For instance, people in some parts of the world use cattle, rather than government backed money, as currency. Cattle is fungible, divisible, transferable, portable, and scarce. Anyway, Ethereum is certainly a currency because it meets all of the above criteria. And yes, Ethereum is still scarce despite having no maximum supply because it still requires mining to acquire Ether tokens.
Is Ethereum a Security? This is the most important question for the growth of Ethereum. Basically, a security is a financial instrument that offers the potential for profit or for loss. A security must be issued by a centralized organization. Ethereum is decentralized, so it is not classified as a financial security. However, the initial coin offerings ICOs and subsequent altcoins that use the Ethereum blockchain are generally classified as securities.
Those coins come from a central authority. And the coins themselves are essentially a share of the company that produces the coin. The Problem With Securities The big problem that cryptocurrencies have when they are classified as securities is the regulation they face as a security compared to a commodity. Simply put, the regulations are much more stringent for a security than the regulations for a commodity.
The most important regulation is that only a licensed security broker could sell the cryptocurrency. Cryptocurrency exchanges are not licensed security brokers, so they would be unable to sell any cryptocurrency classified as a security. The best financial classification for Ethereum is as a commodity. A currency would also work because Ethereum meets the test for classification as a currency. However, Ethereum is a terrible currency because the price is far too volatile.
This could change in the future, but at the moment it does not work very well as a currency. There is an exception to Ethereum as a currency, though. The initial coin offering. ICOs are almost always done in Ethereum. But that does not make it a good option. ICOs use Ethereum because there are fewer regulations than using fiat currency. Final Thoughts Ethereum and most decentralized cryptocurrencies are most likely safe from being classified as a security. A smart contract is basically a robot that executes some code when it receives transactions.
This transaction happens within the blockchain. It is public, replicated and validated by the network. A smart contract has a balance, some code, and some storage. Keys are strings of 32 bytes. Same for values. You would need several billions of times the age of the universe to go through this amount of data with an SSD. The emitter of the transaction pays this tax to motivate the miners to process the transaction. Miners ensure the network is reliable and we reward them with some Ether.
So we send transactions and some fuel to this big machine. Each action of this robot will burn some more gas. There are instructions to read in storage, instructions to write, and so on. Each of these transactions has a cost in fuel, and that cost will constrain how much storage we can use. Storage Cost The cost of each instruction in a Smart Contract will limit the amount of storage it uses.
In theory, Ethereum enables infinite storage space. This cost changes all the time, depending on the network, the market and the way Ethereum specs develop. To get a general idea of the pricing, I simulated a few Smart Contracts: I tried three operations: Writing a uint8 one byte in storage Incrementing a uint8 in the storage read then write A simple voting function, which checks whether the emitter of the transaction has the right to vote and then updates the vote result.
You can vote only once; the second attempt is short-circuited. Code and tools are in the Appendix below. Here are the numbers: note from numbers here are outdated, but the currency is so volatile these days, use this as a rough order of magnitude. Based on this table, this article would cost around 50 Euros to store with a Smart Contract, excluding pictures.
Posting a tweet costs a few euros, and ordering on Amazon a few cents. Of course, these are estimations with different orders of magnitude. The exact cost will depend on the exact instructions you use, as well as on the network load, the current price of gas, etc. New algorithms might also bring down the price of Ethereum Proof Of Stake.
