What is Ethereum?

by | Jan 12, 2023

Ethereum is a distributed public blockchain that provides a decentralized virtual machine. Ether is the cryptocurrency token.

There are two types of accounts in Ethereum: external accounts owned by humans and contract accounts owned by applications.

Ethereum was the first cryptocurrency to implement smart contracts.

A smart contract allows computers to automate tasks that would otherwise require humans and resources. So far, the most successful dApp on the smart contract platform is the Initial Coin Offering (ICO). Second to this is probably the DAO, which is a new type of organization run completely on smart contracts.

In 2016, an unknown hacker stole millions of dollars worth of ether in a DAO hack (but we’ll get into that later)

Ethereum was proposed by a Canadian man named Vitalik Buterin in 2013.

Vitalik Buterin was born in Russia on December 6, 1994. His family moved to Canada at the age of six, and he grew up in Toronto. He attended the University of Waterloo where he studied computer science and mathematics.

Buterin initially started working on Bitcoin Magazine as a writer before becoming interested in an idea he had, which we now know as Ethereum. The goal of Ethereum was to expand upon Bitcoin’s capabilities by making it easier for developers to create applications that could be used for smart contracts or decentralized apps (DApps).

Ethereum is a distributed public blockchain that provides a decentralized virtual machine. It has its own crypto-currency called “ether” that can be traded for other cryptocurrencies or fiat currency.

Ethereum’s blockchain uses smart contracts, which are scripts of code that run on the Ethereum Virtual Machine (EVM). The EVM can execute code of arbitrary algorithmic complexity, leading to potentially unlimited advances in transaction processing and scalability.

Ether is the cryptocurrency token.

Ether (ETH) is the cryptocurrency token of the Ethereum blockchain. It can be used as a payment method to pay for goods and services on the Ethereum network, much like Bitcoin or Litecoin. Ether is also used to pay for transaction fees and computational tasks performed by miners on the Ethereum network.

You can buy Ether using US dollars, Bitcoin, or other cryptocurrencies via an exchange such as Coinbase or Kraken.

Contract accounts can hold ether, but they cannot transfer it out by themselves. Contract owners can send transactions from the contract account to other accounts that they own or to contracts that they control.

Contracts on Ethereum are used for a number of different things, such as creating new tokens (smart contracts), executing bets and bets on the outcome of events (such as elections), managing legal documents like wills or property deeds and many more uses not yet imagined.

Ethereum contains a Turing-complete programming language

If you’re already familiar with Turing machines, feel free to skip ahead.

Turing completeness is a property of programming languages that refers to their ability to handle any computation. A Turing machine is an abstract mathematical model of a computer, which can execute simple instructions on data stored on its tape. The machine has an infinite memory space and can only read one symbol at a time from its tape (but can remember what it read). If the current symbol on the tape matches with an instruction on the program, it performs that instruction; otherwise it moves one step in either direction along its tape. These instructions are encoded as numbers in binary form: each digit 0 or 1 represents an instruction in one direction or another, depending on whether the digit was written before or after “1”.

The Universal Turing Machine (UTM) is able to simulate other computers by following this pattern: if you give me a description of your computer’s hardware in terms of simple operations like reading and writing symbols from/to memory locations etc., I’ll be able to run any algorithm/program for your architecture given enough time (and some additional assumptions about how fast I can move between different parts of memory). The UTM acts like all other computing devices at once – so if we want it simulate multiple instances at once then we need several UTM’s running side-by-side!

The first cryptocurrency to implement smart contracts.

Smart contracts are computer code that can be built into the blockchain to facilitate, verify, or negotiate a contract agreement between two parties.

Smart contracts are self-executing and self-enforcing. The terms of an agreement are written into them, which means no third party is required to arbitrate disputes and no legal system is needed to resolve things when they go awry—everything happens automatically via computer code, the smart contract.

A smart contract is an application that runs on the Ethereum platform and can be programmed to perform tasks related to any number of financial activities. These include:

  • Facilitation of a contract agreement between two parties
  • Verification of pre-programmed conditions (e.g., if X happens, then do Y)
  • Negotiation and enforcement of contractual terms

Ethereum allows developers to build their own decentralized apps (dApps).

A dApp is a program that runs on the Ethereum blockchain. It’s independent of any single computer, server, or cloud. Anyone can access it using a browser and it is not controlled by any single entity.

Computers automate tasks that would require humans and resources otherwise

Computer automation is the process of eliminating human involvement in a work process. In other words, it’s about performing tasks that would normally require humans and resources without having to hire additional employees or purchase more equipment. In many cases, this can save your company money on labor costs and help increase productivity by reducing the time spent on tasks that take up valuable time. Automation is often used to eliminate repetitive tasks, which may include things like collecting data or sorting through data sets. However, it can also be applied to more complicated processes such as making decisions based on experience or intuition—which is why we see so many self-checkout lines at grocery stores these days!

The primary benefit of computer automation is that it saves companies both time and money by eliminating human intervention where possible while still maintaining high quality output (i.e., no mistakes). It allows businesses with limited resources access more efficient ways of doing things than previously available by simply leveraging technology instead of hiring new people for each task needed completed within an organization’s workflow processes.”

So far, the other most successful dApp on the platform is the Initial Coin Offering (ICO).

An ICO is a way to raise money for new cryptocurrency projects. It’s similar to an IPO (Initial Public Offering), but instead of selling shares in your company, you sell digital tokens. These tokens can be used within your network and are sold at different prices depending on how much utility they have within that network.

This can be compared to buying tickets for movies through Fandango.com as opposed to going straight to AMC theaters yourself; with Fandango’s service, there’s more work involved but it allows you access to certain perks like being able to reserve seats in advance and getting discounts on tickets when buying them online versus going straight into a theater.

With an ICO or ITO (Initial Token Offering) token sale, the creator raises money without giving up equity or control over their business idea by allowing users who want access into their system purchase it with their own personal currency instead of fiat currency like dollars or pounds sterling – which could otherwise cause issues if someone wants access but isn’t able because they don’t have any legal tender left after purchasing goods/services from another person!

A DAO is a new type of organization run completely on smart contracts.

The DAO has no leader or hierarchy, it is self-governing and funded by cryptocurrency token holders.

In 2016, an unknown hacker stole millions of dollars worth of ether in a DAO hack. The hack was made possible by a vulnerability in the DAO’s smart contract code. The attacker was able to withdraw funds from the DAO and into their own account by exploiting this vulnerability.

The hacker didn’t realize they had to pay a small transaction fee (gas) for writing data to the blockchain, so they paid no gas costs when retrieving their Ether with “DAO tokens” as well as transferring them between wallets. This left behind telltale signs that allowed investigators to track down who did it.

The currency has been very volatile but has gained in popularity over the years.

Ethereum is the second most popular cryptocurrency after Bitcoin. While it started out as a digital token, Ethereum has grown to become a platform for developers to build decentralized applications (DApps). Ethereum’s token, Ether (ETH), can be used to pay for things online and was created as part of this project.

One important thing to note about ETH: it isn’t a fiat currency like US dollars or euros. Instead, it’s more comparable to stocks in that you can buy and sell them on exchanges such as Coinbase GDAX and Gemini. The value of ETH changes over time based on market demand since there is no central governing body controlling its supply.

As with any investment decision you make yourself or through someone else’s advice, do your own research first before buying anything!
