What Is EOS? EOS has always been one of the most hype over ICO and now a smart contract platform. When it was announced by founder Dan Larimer in New York City in May 2017, a giant jumbotron advertisement could be seen glowing over Times Square. In the first 5 days of their ICO token sale, EOS raised an unprecedented $185 million in ETH — all without having any kind of product or service yet. EOS claims to be “the most powerful infrastructure for decentralized applications.” Basically, EOS is (or, rather, will be) a blockchain technology much like Ethereum. They plan to create their own blockchain with a long list of impressive features. Some are even calling EOS the “Ethereum killer.” But along with all the hype and excitement about EOS, there’s also a large amount of skepticism coming from the crypto community. The EOS Vision EOS has big plans. It will be a software that will act as a decentralized operating system. Developers can then build applications on the EOS software. It will be highly scalable, flexible, and usable. The most notable feature that everyone is getting excited about is horizontal scalability — what this means is the EOS blockchain will be able to allow parallel execution of smart contracts and simultaneous processing of transactions. This could be a real game changer. EOS will incorporate the delegated proof-of-stake (DPoS) consensus protocol, created by founder Dan Larimer himself. This system is less centralized, uses far less energy, and is incredibly fast — as in, up to millions-of-transactions-per-second fast. Furthermore, there will be no user fees on the EOS blockchain. This would also set them apart from the competition and could help them gain more widespread adoption of their platform. EOS also wants to put a blockchain constitution in place to secure user rights and enable dispute resolution. As explained in their technical whitepaper: 'The EOS.IO software is designed from experience with proven concepts and best practices, and represents fundamental advancements in blockchain technology. The software is part of a holistic blueprint for a globally scalable blockchain society in which decentralized applications can be easily deployed and governed.' Tokens that are issued on top of the EOS platform includes Everipedia, HorusPay, Meet One, and more.
Dai is a stablecoin. It is an Ethereum ERC20 token that is pegged to $1 USD — every Dai is worth $1, and will always be worth $1, regardless of how much Dai is in existence. There is no centralized authority like Tether that backs its value, and no traditional bank that backs each Dai with a real US dollar. There is nothing that can be shut down, and no centralized authority that needs to be trusted. Dai lives entirely within the Ethereum blockchain using smart contracts. *Features of Dai: 1. Dai is always worth $1 USD each 2. It can be freely traded like any other ERC20 token 3. Anyone with an Ethereum wallet can own, accept, and transfer it 4. It can be exchanged without any middleman 5. No individual person or company has control over it 6. No government or authority can shut it down *How Dai Works? Dai is a masterpiece of game theory that carefully balances economic incentives in the pursuit of one goal — a token that is continuously approaching the value of $1 USD. When Dai is worth above $1, mechanisms work to decrease the price. When Dai is worth below $1, mechanisms work to increase the price. The rational actors that take part in these mechanisms do so because they earn money anytime Dai is not perfectly worth $1. This is why Dai is always floating slightly above or below $1 — it is an endless wave function bouncing infinitely close to $1, but never quite achieving it. The farther Dai goes from $1, the more incentive there is to fix it. This is the magic of Dai. *How is Dai Created? Dai is simply a loan against Ethereum. By using the MakerDAO dApp, advanced users can take loans out in Dai against their ETH holdings. First, ETH is turned into “wrapped ETH” (WETH), which is simply an ERC20 wrapping around ETH. This “tokenizes” ETH so it can be used like any other ERC20 token. Next, WETH is turned into “pooled ETH” (PETH), which means it joins a large pool of Ethereum that is the collateral for all Dai created. Once you have PETH, you can create a “collateralized debt position” (CDP), which locks up your PETH and allows you to draw Dai against your collateral, which is PETH. As you draw out Dai, the ratio of debt in the CDP increases. There is a debt limit that sets a maximum amount of Dai you can draw against your CDP. Once you have Dai, you can spend or trade it freely like any other ERC20 token. *There are several important reasons why you would create Dai, despite the hassle: 1. You need a loan, and have an asset (ETH) to use as collateral for your loan 2. You believe ETH is going up in value. You can use your CDP to buy ETH on margin — you lock up your ETH in a CDP, draw Dai against it, use the Dai to buy more ETH on an exchange, and then use that ETH to further increase the size of your CDP. This can be accomplished without any third-party or centralized authority allowing you to do so — margin trading can be accomplished entirely on the blockchain. 3. The demand for Dai has driven the price above $1 USD. When this occurs, you can create Dai then immediately sell it on an exchange for greater than $1 USD. This is essentially free money, and is one of the mechanisms the Maker system uses to keep Dai pegged to $1 USD. Dai being worth over $1 USD encourages more Dai to be created. These three reasons are enough to ensure that Dai is continually created.
