Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

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.
