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.
KuCoin is an international cryptocurrency exchange based out of Hong Kong that currently supports the trading of 210 digital assets. What’s unique about KuCoin is that they share 50% of their overall trading fee revenue with users holding their exchange-based token. In a similar fashion to Binance, KuCoin offers relatively low tradings fees and incentives for holding (or trading) its native cryptocurrency. Back in 2011, the founders started researching blockchain tech and went further to build the technical architecture for KuCoin in 2013. 4 years later, the exchange launched with the ultimate goal of “becoming one of the top 10 worldwide hottest exchange platform[s]” by 2019. As stated on their official website which lists 12 core members, “Kucoin aims at providing users digital asset transaction and exchange services which are even more safe and convenient, integrating premium assets worldwide, and constructing state of the art transaction platform”. CEO and founder, Michael Gam, is a former technical expert at Ant Financial, an affiliate company of the Chinese Alibaba Group. He was also a senior partner at Internet giants like MikeCRM and KF5.COM. OO, Eric Don, is referred to as a “senior Internet researcher, systems architect, and Internet industry star”. He is also stated to be the CTO and senior partner of IT companies including YOULIN.COM, KITEME, and REINOT. However, it’s unclear if these websites actually exist as they did not show in a Google search or when entering the website domains. According to his LinkedIn, he is currently CTO at Youlin Network Technologies, yet there is no mention of KITEME or REINOT. With its growing user base and increasing number of cryptocurrencies being offered, KuCoin may be set up for a strong run in the markets. KuCoin Shares volume is expected to grow as the daily trading volume on KuCoin, hence, trading fees collection grows & thus, the size of dividend payout grows. This can lure investors to hold KCS token which may even increase its value. KuCoin faces stiff competition from OKEx, but it expects to continue to grow its community exponentially as it is being projected to be one among the top 5 exchanges in the world.
