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.

Augur is a trustless, decentralized platform for prediction markets. Augur is an Ethereum-based decentralized prediction market that leverages the wisdom of the crowds to create a search engine for the future that runs on its own token, REP. Augur allows users to create their markets for specific questions they may have and to profit from the trading buys while allowing users to buy positive or negative shares regarding the outcome of a future event. Prediction markets are markets created to trade the probability of an event happening. The market prices indicate what the crowd thinks the probability of an event happening. Predictive markets have shown to have been effective in accurately forecasting many results however it is still not widely used due to the many regulatory hurdles involved in setting up such a market. Augur aims to set up such a market in a decentralized manner.

Augur REP is the gambling cryptocurrency. It’s the crypto token you can use to bet on sporting events, political outcomes, economies and just about everything else in the prediction markets. Online gambling is a $52 billion a year industry. At its founding the project included Intrade founder Ron Bernstein, Robin Hanson, and Ethereum founder Vitalik Buterin among its advisers. In April 2015, Augur's first contract was uploaded to the Ethereum network.The first beta version was released in March 2016. In October 2016, all the reputation tokens that were for sale during the 2015 crowdfunding campaign were distributed to their owners on the live Ethereum network and the two largest cryptocurrency exchanges, Poloniex and Kraken, added support for these tokens on their trading platforms. The project was delayed until it was launched in July 2018.
