We\u2019ve designed this guide to appeal to both crowds and expose anyone from complete crypto beginners and intermediates to this potentially world-changing cryptocurrency.<\/p>\n<h2>Ethereum vs. Bitcoin<\/h2>\n<p>If you\u2019re interested in Ethereum, chances are you have some sort of foundational knowledge of <a href=\"https:\/\/coincentral.com\/what-is-bitcoin\/\">Bitcoin<\/a>.<\/p>\n<p>All cryptocurrencies inevitably get compared to Bitcoin, and it frankly makes understanding them much easier.<\/p>\n<p>Bitcoin launched in 2009 as the world\u2019s first cryptocurrency, with the single goal of creating a decentralized universal currency. This currency would not require any intermediary financial institutions, but would still ensure safe and valid transactions. This was made possible by a revolutionary technology called the \u201c<b>blockchain<\/b>.\u201d<\/p>\n<p>The blockchain is a digital ledger, continuously recording and verifying records. It\u2019s used to track and verify Bitcoin transactions. Since the global network of communicating nodes maintains the blockchain, it\u2019s pretty much incorruptible. As new blocks are added to the network, they are constantly validated.<\/p>\n<p>Similar to Bitcoin, Ethereum is a distributed public blockchain network. While both Ethereum and Bitcoin are cryptocurrencies that can be traded among users, there are many substantial differences between the two.<\/p>\n<p>Bitcoin, for example, utilizes blockchain to track ownership of the digital currency, making it an extremely effective peer to peer electronic cash system. Ethereum, on the other hand, <b>focuses on running the programming code of an application<\/b>. Application developers largely use it to pay for services and transaction fees on the Ethereum network.<\/p>\n<p>Both Bitcoin and Ethereum are \u201cdecentralized,\u201d meaning they have no central control or issuing authority. Respective miners run each network by validating transactions to earn either bitcoin (for Bitcoin) or ether (for Ethereum).<\/p>\n<p>If you\u2019re still having trouble making the distinction, the words of<a href=\"https:\/\/gavwood.com\/\" target=\"_blank\" rel=\"noopener\"> Dr. Gavin Wood<\/a>\u2014one of Ethereum\u2019s Co-Founders\u2014might help:<\/p>\n<blockquote>\n<p><img decoding=\"async\" class=\"alignleft\" src=\"https:\/\/coincentral.com\/wp-content\/uploads\/2017\/08\/gavin-wood-150x150.jpg\" alt=\"Dr. Gavin Woode, Ethereum Co-Founder\" width=\"152\" height=\"152\" \/>\u201cBitcoin is first and foremost a currency; this is one particular application of a blockchain. However, it is far from the only application. To take a past example of a similar situation, e-mail is one particular use of the internet, and for sure helped popularise it, but there are many others.\u201d<\/p>\n<h4>Dr. Gavin Wood, Ethereum Co-Founder<\/h4>\n<\/blockquote>\n<p>Ethereum is simply the application of blockchain technology for a completely different purpose.<\/p>\n<h2><b>What is Ethereum?<\/b><\/h2>\n<p>Simply put, Ethereum is a blockchain-based decentralized platform on which decentralized applications (Dapps) can be built.<\/p>\n<ul>\n<li>Remember, blockchain isa database with no central server that keeps track of every transaction and exchange. The vast majority of cryptocurrencies and decentralized projects run on some application of blockchain.<\/li>\n<li>We\u2019ll jump into decentralized apps\u2014referred to as dapps\u2013in greater detail later, but just know they are applications that serve a specific purpose to a user. Fasten your seatbelts, some of these dapps are amazing.<\/li>\n<\/ul>\n<p>Ethereum\u2019s appeal is that it&#8217;s built in a way that enables developers to create smart contracts. <b>Smart contracts<\/b> are scripts that automatically execute tasks when certain conditions are met. For example, a smart contract could technically say, \u201cpay Jane $10 if she submits a 1000 word article on goats by September 15, 2018,\u201d and it would pay Jane once the conditions are met.<\/p>\n<p>These smart contracts are executed by the Turing-complete Ethereum Virtual Machine (EVM), run by an international public network of nodes.<\/p>\n<p>The cryptocurrency of the Ethereum network is called <b>ether<\/b>. Ether serves two different functions:<\/p>\n<ol>\n<li>\u00a0\u00a0\u00a0<b>Compensate the mining full nodes that power its network. <\/b>This keeps things running smoothly at an administrative level.<\/li>\n<li>\u00a0\u00a0\u00a0<b>Pay people under smart contract conditions.<\/b> This is what motivates users to work on the Ethereum platform.<\/li>\n<\/ol>\n<p>If you\u2019re still a little confused, don\u2019t worry.

Lubin moved on to found the now near 1,000-employee Brooklyn-based &#8220;venture production studio&#8221; ConsenSys.<\/p>\n<p>Rumored to be one of the top buyers in the Ethereum crowdsale, Lubin, who had been funding ConsenSys with his stash of Bitcoins, says he began selling some of his Ethers last year to fund the firm&#8217;s development<\/p>\n<h2><b>The Ethereum Virtual Machine<\/b><\/h2>\n<p>Early blockchain applications like Bitcoin only allowed users a set of predefined operations. For example, Bitcoin was created exclusively to operate as a cryptocurrency.<\/p>\n<p>Unlike these early blockchain projects, Ethereum allows users to create their own operations. \u00a0The <b>Ethereum Virtual Machine <\/b>(EVM) makes this possible. As Ethereum\u2019s runtime environment, the EVM executes <b>smart contracts<\/b>. Since every Ethereum node runs the EVM, applications built on it reap the benefits of being decentralized without having to build their own blockchain.<\/p>\n<h2><b>Smart Contracts<\/b><\/h2>\n<p>Smart contracts are strings of computer code capable of automatically executing when certain predetermined conditions are met.<\/p>\n<p>Instead of requiring a single central authority to say \u201cyay\u201d or \u201cnay,\u201d these contracts are self-operated. This not only makes the entire process more effective, it also makes it more fair and objective.<\/p>\n<p>For example, a simple smart contract use case would be:<\/p>\n<ul>\n<li>\u00a0\u00a0\u00a0\u00a0Jim wants to bet Sarah 100 Ether (ETH) that the price of ETH will be above $1000 on August 30th, 2018.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0They agree on a data feed to be used to determine the ETH price.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0They each escrow 100 ETH to a smart contract, with the winner taking the full 200 ETH.<\/li>\n<li>\u00a0\u00a0\u00a0\u00a0On August 30th, 2018 the data feed is queried and the contract immediately executes <b>sending money to the winner.<\/b><\/li>\n<\/ul>\n<p>Using the smart contract, there\u2019s no need for Jim and Sarah to trust each other. They just have to trust the data feed.<\/p>\n<p>Keep in mind that this is only a very simple example. Many smart contracts are extremely complex and can work wonders.<\/p>\n<p>The takeaway: Smart contracts can automate a variety of tasks, without requiring intermediaries. <b>All a smart contract needs is the arbitrary rules written into it.<\/b><\/p>\n<h2><strong>Ethereum&#8217;s Challenges and Initiatives<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">Handling financial transactions alone presents hugely complex problems in terms of reliability and security. \u00a0And since the Ethereum network comprises a general purpose blockchain that handles assets other than money, more complex challenges arise beyond mere financial transactions. \u00a0Moving into the future, Ethereum confronts issues of scalability, energy consumption, security, privacy, and decentralization.<\/span><\/p>\n<h3><strong>Beyond Money<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">As a general purpose blockchain, Ethereum needs a mechanism to represent assets other than money. \u00a0<\/span><a href=\"https:\/\/coincentral.com\/future-of-erc-721-and-unique-assets\/\"><span style=\"font-weight: 400;\">The ERC-721 standard<\/span><\/a><span style=\"font-weight: 400;\"> has been created to transact unique items of value. \u00a0The ERC acronym stands for Ethereum Request for Comment and provides a formal process for the Ethereum Foundation to improve its product. \u00a0The ERC-721 standard originally drove the development of the highly successful CryptoKitties collectibles, but it allows for the representation of any digital asset.<\/span><\/p>\n<h3><strong>Casper The Friendly Finality Gadget<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Any blockchain relies on a <\/span><a href=\"https:\/\/coincentral.com\/ethereum-mining-in-the-era-of-asics\/\"><span style=\"font-weight: 400;\">trustworthy, fair, secure, and reliable consensus protocol<\/span><\/a><span style=\"font-weight: 400;\"> for placing transactions onto the system. \u00a0Like Bitcoin, Ethereum uses a Proof of Work (PoW) approach, but the Ethereum blockchain plans to implement a Proof of Stake (PoS) algorithm.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-9706\" src=\"https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper.png\" alt=\"Ethereum casper\" width=\"928\" height=\"524\" srcset=\"https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper-591x333.png 591w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper-621x350.png 621w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper-300x169.png 300w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper-799x450.png 799w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/Ethereum-casper-600x338.png 600w\" sizes=\"(max-width: 928px) 100vw, 928px\" \/><\/p>\n<p><a href=\"https:\/\/coincentral.com\/what-is-casper-the-friendly-haunting-of-ethereum\/\"><span style=\"font-weight: 400;\">The Casper finality gadget<\/span><\/a><span style=\"font-weight: 400;\"> implements PoS as an independent module. \u00a0As an independent module, Casper lives on top of the current PoW system, making the Ethereum network a hybrid system of both PoW and PoS. \u00a0Also as an independent module, this allows the PoW portion of the network to be removed at a later date.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The Casper PoS protocol utilized game theory incentives to maintain the integrity of the system. \u00a0It also provides benefits of greater security and reduces the massive energy consumption required by PoW mining.<\/span><\/p>\n<h3><strong>Scaling the Heights<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Scaling presents a great challenge for Ethereum, as it does for other blockchains. \u00a0Scaling defines a system&#8217;s ability to handle a large and growing workload without showing strain or stress to the system. \u00a0Think of this both as a system&#8217;s power and efficiency to complete tasks and also as a user experience challenge. If a user waits too long for a response after clicking a button, frustration results, and users give up on the system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The web confronted this problem in the early days as well. \u00a0In the first web applications, every action a user took on a web page resulted in the entire page having to be reloaded from the server and rendered again on the client&#8217;s browser. \u00a0Web 2.0 came along, introduced the ability to refresh only the relevant part of the page, and responsive user interfaces became the norm on the internet.<\/span><\/p>\n<h3><strong>Vitalik Buterin on Scaling<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Vitalik Buterin identifies scaling as a primary concern that needs to be addressed in blockchain technology. \u00a0<\/span><a href=\"https:\/\/www.youtube.com\/watch?v=WSN5BaCzsbo\" target=\"_blank\" rel=\"nofollow noopener\"><span style=\"font-weight: 400;\">He made the following comments<\/span><\/a><span style=\"font-weight: 400;\"> in September 2017 in an interview with Naval Ravikant at the Disrupt SF 2017 conference.<\/span><\/p>\n<blockquote>\n<p><span style=\"font-weight: 400;\">\u201cBitcoin is currently processing a bit less than three transactions a second; and if it goes close to four, it&#8217;s already at peak capacity.

Dapps serve similar functions, but run on an entire network of nodes rather than a central source. The fact that they are decentralized gives dapps an enormous advantage over traditional apps.<\/p>\n<p>You know when Instagram is down <b>because the server is down<\/b>? This doesn\u2019t happen with dapps. How about when Zomato <b>got hacked<\/b> and exposed the information of 17 million people?

Bitcoin transactions are limited by block size and compete with each other.<\/li>\n<li><b>More Sophisticated Mining<\/b> \u2013 Bitcoin mining currently requires ASICs (Application-Specific Integrated Circuits), necessitating a large amount of capital investment to mine. \u00a0Ethereum\u2019s mining algorithm was designed with ASIC-resistance in mind, thus leveling the playing field and aiding in the decentralization of mining.<\/li>\n<\/ol>\n<p>Ethereum arguably currently functions better than Bitcoin as a currency. With Ethereum, you can reliably send transactions faster,<a href=\"https:\/\/bitinfocharts.com\/comparison\/transactionfees-btc-eth.html\" target=\"_blank\" rel=\"noopener\"> pay lower transaction fees<\/a>, and mine at a more profitable rate (although it still has its downfalls for miners).<\/p>\n<p><em><a href=\"https:\/\/coincentral.com\/?p=4132&amp;preview=true\">Read: Is Ethereum Mining Profitable?<\/a><\/em><\/p>\n<p>However, Bitcoin does have a relatively more stable price\u2014and therefore functions as a better value storage option\u2014from a trading and value storage perspective. Ethereum is much younger but has covered a substantial amount of ground in recent years. Although Ethereum certainly shows promise as a currency, its true potential lies in features nonexistent in Bitcoin\u2019s code.<\/p>\n<h3><b>The DAO: Trouble in Paradise<\/b><\/h3>\n<p>The most famous DAO was simply known as The DAO. The nearly identical name causes a lot of confusion for people and gives DAOs a bad reputation.<\/p>\n<p>The DAO was a decentralized autonomous organization primarily functioning as its own investor-directed venture capital fund. It didn\u2019t have the conventional management structure or board of directors, was not tied to any particular government, and instead ran on open source code. The DAO was set up to give funders the power to vote for which dapps deserved investment through DAO tokens.<\/p>\n<p>Dapps had somewhat of an approval process:<\/p>\n<ol>\n<li>\u00a0\u00a0\u00a0Get whitelisted by reputable figureheads in the Ethereum community<\/li>\n<li>\u00a0\u00a0\u00a0Get voted on by those who held DAO tokens<\/li>\n<li>\u00a0\u00a0\u00a0Get an approval of 20% in the vote in order to receive a share of DAO funds they required to get started.<\/li>\n<\/ol>\n<p>The DAO is most famous for the largest crowdfunding campaign in history, raising over $150 million in ether from more than 11,000 investors. The DAO is also most infamous for getting hacked for $50 million. This hack inevitably caused a split in the Ethereum community, creating what we now know as Ethereum (ETH) and Ethereum Classic (ETC).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/coincentral.com\/wp-content\/uploads\/2017\/08\/etheruem-classic.png\" alt=\"Ethereum Classic\" width=\"1200\" height=\"500\" \/><\/p>\n<p>The hack happened because of The DAO\u2019s \u201cSplit Function.\u201d Funders who wanted to exit The DAO could use its \u201cSplit Function,\u201d which would give them back the ether they had invested. The only stipulation was that existing funders had to hold their ether for 28 days before they could withdraw them.<\/p>\n<p>On June 17th 2016, an unknown person or group of people took advantage of a lapse in the Split Function\u2019s security with a simple recursive function. This frustratingly easy hack allowed the hacker(s) to repeat their request to withdraw the same DAO tokens multiple times before the system registered it as $50 million.<\/p>\n<p>The news of this hack created chaos in the Ethereum community. While this hack had nothing to do with the Ethereum platform and everything to do with The DAO platform, many members of the Ethereum community were invested in The DAO. The community as a whole had 28 days to come up with a solution, which ended up being to \u201cfork\u201d\u2014stop the current blockchain entirely and create something new from scratch.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10944\" src=\"https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack.png\" alt=\"dao hack\" width=\"2000\" height=\"1125\" srcset=\"https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack.png 2000w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-591x332.png 591w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-621x349.png 621w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-300x169.png 300w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-768x432.png 768w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-800x450.png 800w, https:\/\/coincentral.com\/wp-content\/uploads\/2018\/06\/dao-hack-600x338.png 600w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/p>\n<p>The new Ethereum (ETH) is the result of the fork, and is essentially the blockchain before the hack.

This hard fork indicates some major upgrades for the platform including:<\/p>\n<ol>\n<li>Increased anonymity with new zero-knowledge proofs, or \u201czk-SNARKs.\u201d This means users will be able to conduct transactions at much more secure levels of anonymity than ever before.<\/li>\n<li>Smart contracts and programming will be much easier to work with. Gas is also going to be adjusted for bill setting.<\/li>\n<li>Masking will increase security on the network. Users will be able to determine the address for which they have a private key, and this will protect them from quantum computer hacking.<\/li>\n<li>A \u201cdifficulty bomb\u201d will be included in the upgraded, meaning mining will become much more difficult. This is a significant step as Ethereum transitions from proof-of-work (PoW) to proof-of-sake (PoS).<\/li>\n<\/ol>\n<p>We won\u2019t know how this hard fork will affect the price of Ethereum as markets could adjust in a variety of ways. If the upgrades attract more users, the price could rise. However, if mining becomes more difficult and slows, the price could fall.<\/p>\n<p>The next upgrade after Metropolis is referred to as Serenity, which should increase stability and<a href=\"https:\/\/cointelegraph.com\/news\/is-ethereum-getting-ready-for-mass-adoption\" target=\"_blank\" rel=\"noopener\"> encourage more investment<\/a>.<\/p>\n<h2>Final Thoughts<\/h2>\n<p>While there is a lot of speculative interest around Ethereum, it\u2019s important to note that the Ethereum and dapp communities are very much focused on building a tangible future.<\/p>\n<p>Ethereum is a phenomenal application of the blockchain and has made it possible for hundreds of projects to exist.<\/p>\n<blockquote>\n<p>\u201cBlockchain solves the problem of manipulation.
