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.
EtherZero, abbreviated ETZ, is a hard fork on ethereum providing no-fee, high expansibility, real-time transaction or operation feedback services. Aiming to be a general-purpose smart contract platform, ETZ helps developers set up DAPPs that not limited in finance and business scope, but those more frequently used in daily life, to popularize decentralized services to more people and industries. ETZ eliminates the gas fee system from Ethereum network core and adds a Transaction Restriction Policy Protocol layer that associates the threshold, frequency, depth, etc. of initiating transactions with the account balance to combat DDOS like attacks. In particular, ETZ also draws on DASH's two-tier network architecture built with Masternodes transaction verification network and blockchain ledger layer, and its built-in community autonomous system to provide users with real-time operation feedback and high transaction concurrency, no longer need to wait for a long transaction confirmation time. ETZ picks the proven experience of Ethereum on smart contracts, removes its less scalability gas-based fee system and designs a fully accountable trading limit and security strategy against DDOS Class attacks. The final two-tier network composed of the main node and pow consensus layer laid the foundation to achieve free of charge, high concurrency, real-time transactions, independent evolution and several other features. What does no-fee mean to DApp Dev? Taking a simple Todolist DApp as an example, its decentralized implementation can be applied to the team task decomposition process, which requires all participants in the project to know the tasks of other members. Each task is a team consensus result with demand of traceability. The application involves registration of members, additions, deletions and alterations of tasks. According to Ethereum development requirements, all of these operations require gas consumption, which is clearly unreasonable for the users of the application. While in EtherZero, the transaction initiation frequency and the execution depth of smart contracts will be positively related to the balance possessed by the account. This mechanism is similar to POS, it takes into account the fair use of bandwidth and set a relatively high capital threshold required to launch a DDOS attack by malicious attackers while providing free services. This kind of limited and cost-effective free mechanism will spread the decentralized application into the scene of life.
