Ethereum Definition | Investopedia
Launched in 2015, Ethereum is a decentralized software platform that enables SmartContracts and Distributed Applications (Apps) to be built and run without any downtime, fraud, control or interference from a third party. Ethereum is not just a platform but also a programming language (Turing complete) running on a blockchain, helping developers to build and publish distributed applications. The potential applications of Ethereum are wide ranging. The applications on Ethereum are run on its platform-specific cryptographic token, ether. During 2014, Ethereum had launched a pre-sale for ether which had received an overwhelming response. Ether is like a vehicle for moving around on the Ethereum platform, and is sought by mostly developers looking to develop and run applications inside Ethereum. Ether is used broadly for two purposes, it is traded as a digital currency exchange like other cryptocurrencies and is used inside Ethereum to run applications and even to monetize work. The current market cap of ether (ETH) is now more than Ripple and Litecoin although its far behind bitcoin (BTC). According to Ethereum, it can be used to codify, decentralize, secure and trade just about anything. One of the big projects around Ethereum is Microsofts partnership with ConsenSys which offers Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure so Enterprise clients and developers can have a single click cloud based blockchain developer environment.

What Is Ethereum? Here's Everything You Need To Know | Digital Trends
Deep-learning algorithms help study brain waves to predict seizures Get today's popular DigitalTrends articles in your inbox: If you follow tech or financial news, youve probably seen the name Ethereum popping up over the last couple years, often in connection with bitcoin. Ethereum is a rising star in the world of cryptocurrencies , entirely digital forms of currency that grew in popularity after the creation of bitcoin by a person or group calling themselves Satoshi Nakamoto in 2009. Demand for Ethereum is so high that it may even be driving up the price of graphics cards , as miners try to generate as much currency as they can. What is Ethereum exactly, and what does it mean for the future of cryptocurrency (and maybe society)? Heres the rundown. People often refer to Ethereum as a cryptocurrency, but that isnt precisely true. It is a platform that allows individuals to conduct transactions and draw up contracts, using a currency called ether. To understand what distinguishes Ethereum from a cryptocurrency like bitcoin, it helps to understand what a cryptocurrency is, as well as the concept of a blockchain. A cryptocurrency is a form of digital currency created through encryption. A cryptocurrency has no physical form like a banknote or coin and it is not issued by a central bank or governmental authority. Units of cryptocurrency exist as data on the internet, and are created and managed through something called a blockchain. A blockchain is essentially a digital ledger, shared amongst any number of computers. When transactions occur, they are recorded in blocks; in order for these blocks to go into the ledger, they must be validated by a certain number of computers on the blockchain network. Crucially, the ledger exists, in the same form, for everyone on the networ Continue reading >>
Bitcoin Vs Ethereum: Driven By Different Purposes
Bitcoin Vs Ethereum: Driven by Different Purposes Ethereum has received a lot of attention since its announcement at the North AmericanBitcoinConference in early 2014 byVitalikButerin. The natural consequence of its rising popularity has been its constant comparison toBitcoin, the first virtual currency. It is important for investors to understandthe similarities and differences between BitcoinandEthereum. Bitcoin, the first virtual currency, was born seven years back. It introduced a novel idea set out in a white paper by the mysterious SatoshiNakamoto:Bitcoinoffers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government issued currencies . There are no physicalBitcoins , only balances associated with public and private keys. Over these years, the acceptance of the concept of a virtual currency has increased among regulators and government bodies.Althoughit isnt a formally recognized medium of payment or store of value, it has managed a niche for itself and continues to coexist in the financial system despite being regularly scrutinized and debated. The attempts to understandBitcoinmoreclosely resulted in the discovery of blockchain , the technology that powers it. Theblockchainis not just the hottest topic in theFinTechworld but also asought after technology in many industries. Ablockchainis a public ledger of all transactions in a given system that have ever been executed. It is constantly growing as completed blocks are added to it. The blocks are added to theblockchainin linear, chronological order through cryptography, ensuring they remain beyond the power of manipulators. Theblockchainthus stands as a tamper-proof record of all transactions on the network, accessible to all Continue reading >>

The Ethereum Project's logo, first used in 2014 Ethereum is an open-source , public, blockchain -based distributed computing platform featuring smart contract (scripting) functionality.  It provides a decentralized Turing-complete virtual machine , the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum also provides a cryptocurrency token called "ether", which can be transferred between accounts and used to compensate participant nodes for computations performed.  "Gas", an internal transaction pricing mechanism, is used to mitigate spam and allocate resources on the network.   Ethereum was proposed in late 2013 by Vitalik Buterin , a cryptocurrency researcher and programmer. Development was funded by an online crowdsale between July and August 2014.  The system went live on 30 July 2015, with 11.9 million coins "premined" for the crowdsale.  This accounts for approximately 13 percent of the total circulating supply. In 2016, as a result of the collapse of The DAO project, Ethereum was forked into two separate blockchains - the new forked version became Ethereum (ETH), and the original continued as Ethereum Classic (ETC).    Ethereum was initially described in a white paper by Vitalik Buterin ,  a programmer involved with Bitcoin Magazine , in late 2013 with a goal of buildin Continue reading >>
What Is Ethereum?
We dive into one of the world's most popular cryptocurrencies, from a simple explanation of what Ethereum is to some of the currency's uses and drawbacks(and what it has to do with cats). Think of Ethereum as bitcoins multi-talented, more versatile younger sibling. Bitcoin wasbuilt using a tech called blockchain to create a global, distributed ledger of transactions. This ledger or digital history is stored on hundreds of thousands of computers. So it cant be spoofed or changed. Its controlled by no one and secured by cryptography. Become an expert on blockchain in this live briefing. Well provide the definitions and analogies you need to know for bitcoin, blockchain, cryptocurrencies, and more. But bitcoin is limited in what it can do. On the strength of blockchain, bitcoin has grown into a trusted system for exchanging and storing value. But what if you want to negotiate an economic agreement or a future transaction? Put differently, where else might an unchangeable decentralized record prove useful? To answer this question, Ethereum used the same blockchain technology to create smart contracts, allowing programmers to create code that binds two parties to an agreement without an intermediary needed. Ethereum contracts have been created to distribute insurance payments, to run prediction markets, and more. Heres a quick take on how a smart contract works vs. a traditional contract: In this report, well explain Ethereum, a decentralized platform that runs smart contracts, and a protocol on which many teams are building new applications. In a previous explainer, we examined bitcoin and blockchain technology in depth . But well review the key concepts here as well before we dive in. Its hard to separate Bitcoin from blockchain technology. Still, if we were to define blo Continue reading >>
What Is Ethereum? A Step-by-step Beginners Guide
If you want to know what is Ethereum and how it works and what it can be used for, without going deep into the technical abyss, this guide is perfect for you. Important Note: This guide assumes a basic understanding of blockchain technology. If youre unfamiliar with blockchain, check out this step by step introduction for beginners . Beyond Bitcoin & first generation decentralized applications Although commonly associated with Bitcoin , blockchain technology has many other applications that go way beyond digital currencies. In fact, Bitcoin is only one of several hundred applications that use blockchain technology today. [Blockchain] is to Bitcoin, what the internet is to email. A big electronic system, on top of which you can build applications. Currency is just one. Sally Davies, FT Technology Reporter Until relatively recently, building blockchain applications has required a complex background in coding, cryptography, mathematics as well as significant resources. But times have changed. Previously unimagined applications, from electronic voting & digitally recorded property assets to regulatory compliance & trading are now actively being developed and deployed faster than ever before. By providing developers with the tools to build decentralized applications, Ethereum is making all of this possible. At its simplest, Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications. Is Ethereum similar to Bitcoin? Well, sort of, but not really. Like Bitcoin , Ethereum is a distributed public blockchain network. Although there are some significant technical differences between the two, the most important distinction to note is that Bitcoin and Ethereum differ substantially in purpose and capabil Continue reading >>
What Is Ether?
Ether is a necessary element a fuel for operating the distributed application platform Ethereum. It is a form of payment made by the clients of the platform to the machines executing the requested operations. To put it another way, ether is the incentive ensuring that developers write quality applications (wasteful code costs more), and that the network remains healthy (people are compensated for their contributed resources). If you just want to test the technology, you probably don't need real ether. Download the latest Wallet app and switch to the Test Network Check your ether presale balance safely here: The total supply of ether and its rate of issuance was decided by the donations gathered on the 2014 presale. The results were roughly: 60 million ether created to contributors of the presale 12 Million (20% of the above) were created to the development fund, most of it going to early contributors and developers and the remaining to the Ethereum Foundation 5 ethers are created every block (roughly 15 seconds) to the miner of the block 2-3 ethers are sometimes sent to another miner if they were also able to find a solution but his block wasn't included (called uncle/aunt reward) Note that after the Byzantium update is implemented, the mining and uncle reward is reduced to 3 ethers and 0.625-2.625 ethers, respectively. No. According to the terms agreed by all parties on the 2014 presale, issuance of ether is capped at 18 million ether per year (this number equals 25% of the initial supply). This means that while the absolute issuance is fixed, the relative inflation is decreased every year. In theory if this issuance was kept indefinitely then at some point the rate of new tokens created every year would reach the average amount lost yearly (by misuse, accidental key Continue reading >>
What Is Ethereum And How Does It Differ From Bitcoin?
What is ethereum and how does it differ from Bitcoin? The ethereum cryptocurrencyCredit:Bloomberg Ethereum is a rising star in the cryptocurrency world. It has quickly become the second largest digital currency in just over two years, booming in value and spurring the rise of hundreds of new rivals to Bitcoin. Launched in 2015, the value of ether (ethereum's currency)has increased rapidly. It suffered a set back before Christmas 2017, suddenly dropping from $850 to around $690 -a drop of about 20 per cent. Since then it has continued to show intense volatility, hitting highs of $1400 in January before slumping to less than $560.

What Is Ethereum? Ethereum Homestead 0.1 Documentation
Ethereum is an open blockchain platform that lets anyone build and use decentralized applications that run on blockchain technology. Like Bitcoin, no one controls or owns Ethereum it is an open-source project built by many people around the world. But unlike the Bitcoin protocol, Ethereum was designed to be adaptable and flexible. It is easy to create new applications on the Ethereum platform, and with the Homestead release, it is now safe for anyone to use those applications. Blockchain technology is the technological basis of Bitcoin, first described by its mysterious author Satoshi Nakamoto in his white paper Bitcoin: A Peer-to-Peer Electronic Cash System, published in 2008. While the use of blockchains for more general uses was already discussed in the original paper, it was not until a few years later that blockchain technology emerged as a generic term. A blockchain is a distributed computing architecture where every network node executes and records the same transactions, which are grouped into blocks. Only one block can be added at a time, and every block contains a mathematical proof that verifies that it follows in sequence from the previous block. In this way, the blockchains distributed database is kept in consensus across the whole network. Individual user interactions with the ledger (transactions) are secured by strong cryptography. Nodes that maintain and verify the network are incentivized by mathematically enforced economic incentives coded into the protocol. In Bitcoins case the distributed database is conceived of as a table of account balances, a ledger, and transactions are transfers of the bitcoin token to facilitate trustless finance between individuals. But as bitcoin began attracting greater attention from developers and technologists, novel p Continue reading >>

What Is Ethereum?
Ethereum is a decentralized ledger protocol and a platform that promises unprecedented opportunities for developers of applications running on blockchain, both financial and non-financial. Ethereum is a decentralized ledger protocol and a platform that promises unprecedented opportunities for developers of applications running on blockchain, both financial and non-financial. Ethereum, eth, cryptocurerncy, decentralized Ethereum is a platform for creation of decentralized applications running on blockchain, through the use of smart contracts. Since its launch on June 30, 2015 , it has been steadily gaining popularity . Starting from late January 2016, it has experienced a surge. In March 2016, within less than a year of its existence, that growth culminated in Ethereum achieving a record-breaking market capitalization of over $1B . Since then, the passions have subsided and Ethereum has declined a bit. However, the coin is now second only to Bitcoin on the cryptocurrency market capitalization list. - The graphical representation of how Ethereum has been killing it Bitcoin has undergone a similar explosion of growth in the late 2013 - early 2014, when its price has reached its all-time high . Launches of several hundreds, if not thousands of different kinds of alternative cryptocurrencies followed. Some of those altcoins have managed to reach a certain degree of success, but none of them have achieved the heights of Ethereum. The platform has even enjoyed Microsofts attention, when it announced the launch of Ethereum Blockchain as a Service (EBaaS) based on the Microsoft Azure platform back in November 2015. Now the reader might be wondering: why did all of that happen? Well heres the short version: Ethereum is decentralized, like Bitcoin, but is capable of much, much mo Continue reading >>
What Is Ethereum, In Layman's Term?
When we use our computers and use Word docs or other files we normally save them in folders. A folder with docs, photos, spreadsheets, music files, other files, etc. could be called our database. When we use Facebook, for example, we don't keep that "database" of photos, status reports, messages, links, etc in our computer, Facebook keeps a database of all our activities on their servers in a data-center, which is a building full of servers (powerful computers). In the case of Bitcoin instead of using Facebook, or any other service, to store our stuff in their databases, we download a software that is more or less like Skype, and instead of sending and receiving voice or video or text between us we send and receive units called bitcoins. The Bitcoin software (Bitcoin Core) instead of centralizing "the database" in a service like Facebook or Google or Dropbox, it keeps a copy of the database on your laptop or PC. Imagine 10 friends at a bar around a table and everybody with a laptop and a copy of Bitcoin. Each laptop has the complete database of the Bitcoin list of accounts and transactions. When friend A sends 1 bitcoin to friend B it sends the message to all 10 laptops and they all check that the balance is correct, the accounts, etc. and after checking (and doing some other calculations) they all agree to post, on the databases that they all have in their disks, the new transaction. The Bitcoin database is called a blockchain, because of how it operates, and the process by which all computers check transactions and reach an agreement is called "consensus" (there is another process called mining, but I think it's not relevant in a layman's explanation). The world changing invention of Bitcoin is that all computers participating in the network can keep this "distribute Continue reading >>
What Is Ethereum? How Bitcoin's Major Rival Works | Money
Bitcoin gets the lions share of the attention in the cryptocurrency space. But Bitcoin isnt even the best-performing cryptocurrency around especially now that it has lost 40% of its value from its peak at the start of this week to around $12,000. That means Bitcoin is up around 12-fold this year. By comparison, rival Ethereum has seen its value jump more than 60 times from $8.40 at the beginning of the year to around $530, and thats counting Fridays big across-the-board slide in cryptocurrency prices. What is Ethereum? And does it deserve the same exuberance (rational or otherwise) that Bitcoin is garnering today? Heres everything you need to know. 1. Ethereum is the second-largest cryptocurrency in the world. The total value of Ether in the global marketplace is more than $53 billion . While that still pales in comparison to the $205 billion value on Bitcoins circulating around the world, ethereum is well ahead of other major digital currencies such as Ripple ($21 billion), Litecoin ($10 billion), and IOTA ($9 billion). 2. Ether can be mined like Bitcoin, but with a key difference. Both Ethereum and Bitcoin rely on so-called blockchain technology , a system in which transactions are not recorded and verified by a central bank or institution but rather by a decentralized network of cryptocurrency users. As incentive for those users to serve this function, they are allowed mine for new Bitcoin or Ether to create wealth. However, the total number of Bitcoin that is allowed to circulate in the system is capped at 21 million . And right now, its estimated that there are roughly 16 million Bitcoins in circulation. So from that perspective, Bitcoin is maturing fast. Ethereum, on the other hand, does not have a similar overall cap. There is, however, an annual limit on new is Continue reading >>
What Is Ethereum? - Coindesk Guides
Before you can understand ethereum, it helps to first understand the internet. Today, our personal data, passwords and financial information are all largely stored on other people's computers in clouds and servers owned by companies like Amazon, Facebook or Google. Even this CoinDesk article is stored on a server controlled by a company that charges to hold this data should it be called upon. This setup has a number of conveniences, as these companies deploy teams of specialists to help store and secure this data, and remove the costs that come with hosting and uptime. But with this convenience, there is also vulnerability. As we've learned, a hacker or a government can gain unwelcome access to your files without your knowledge, by influencing or attacking a third-party service meaning they can steal, leak or change important information. Brian Behlendorf, creator of the Apache Web Server, has gone so far as to label this centralizeddesign the "original sin" of the Internet. Some like Behlendorf argue the Internet was always meant to be decentralized, and a splintered movement has sprung up around using newtools, including blockchain technology, to help achieve this goal. Ethereum is one of the newest technologies to join this movement. While bitcoin aims to disrupt PayPal and online banking, ethereum has the goal of using a blockchain to replace internet third parties those that store data, transfer mortgages and keep track of complex financial instruments. In short, ethereum wants to be a 'World Computer' that would decentralize and some would argue, democratize the existing client-server model. With ethereum, servers and clouds are replaced by thousands of so-called "nodes" run by volunteers from across the globe (thus forming a "world computer"). The vision is that Continue reading >>
A Gentle Introduction To Ethereum
Ethereum builds on blockchain and cryptocurrency concepts, so if you are not familiar with these, its worth reading a gentle introduction to bitcoin and a gentle introduction to blockchain technology first. This article assumes the reader has a basic familiarity with how Bitcoin works. Ethereum is software running on a network of computers that ensures that data and small computer programs called smart contracts are replicated and processed on all the computers on the network, without a central coordinator. The vision is to create an unstoppable censorship-resistant self-sustaining decentralised world computer. The officialwebsite is Itextends the blockchain concepts from Bitcoin which validates, stores, and replicates transaction data on many computers around the world (hence the term distributed ledger). Ethereum takes this one step further, and also runs computer code equivalently on many computers around the world. What Bitcoin does for distributed data storage, Ethereum does for distributed data storage plus computations. The small computer programsbeing run are called smart contracts, and the contractsare run by participants on their machines using asort ofoperating system called a Ethereum Virtual Machine. To run Ethereum, you can download (or write yourself if you have the patience) some software called an Ethereum client. Just like BitTorrent or Bitcoin, the Ethereum client will connect over the internet to other peoples computers running similar client softwareand start downloading the Ethereum blockchain from them to catch up. It will also independently validate that each block conforms to the Ethereum rules. What does the Ethereum client software do? You can use itto: Create new transactions and smart contracts Your computer becomes a node on the network, r Continue reading >>
