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.
Decentraland is an Ethereum-powered virtual reality platform. In this virtual world, you purchase plots of land that you can later traverse, build upon, and monetize. There’s no limit to what you can do. It’s the first digital platform that’s completely owned by its users. Similar to games like Skyrim and Fallout, Decentraland is an all-immersive virtual universe. However, instead of playing on a 2-dimensional screen, you participate in a 3-dimensional world. It seems to be the logical next step before creating full-blown AI-based games in the physical space à la Westworld. Similar groupings on LAND comprise Districts. Districts are basically communities that revolve around a shared theme. For example, there may be a District just for crypto enthusiasts with cryptocurrency apps and services. The Decentraland team is led by Ari Meilich (Project Lead) and Esteban Ordano (Tech Lead). Ordano previously worked at Bitpay as a software engineer and founded Smart Contract Solutions, Inc. Both founders have also worked together in creating Stremium and Bitcore. Decentraland has been around for longer than you may think. The team hit their first development milestone, Stone Age, in June 2015. This was a simple, pixelated grid that allocated pixels to users through a proof-of-work algorithm. Most recently, they held a Terraform Event in which they sold LAND in the new, 3D world. The team has also partnered with district0x, Aragon, and imToken to provide some of their services. MANA is the token used to buy lands in Decentraland. The Blockchain platform can be incorporated in order to buy or sell the various digital assets available in the virtual world. An unclaimed land would have the same market pricing on every exchange possible and precisely the developers are on a hunt for such since as they can build on top of it, and attract lot of popularity. However, one must keep in mind that the land parcels are different from them and each one of them varies according to the various market conditions of that time. Mana can be a great investment and can be bought by trading and with other Bitcoin, Ethereum, or any other prominent cryptocurrency and on some of the most notable cryptocurrency exchanges. Specifically, Binance and Huobi are two of the best cryptocurrency exchanges that one can suggest for trading Mana tokens. The Decentraland coin isn’t a minable cryptocurrency as it is issued on the Ethereum blockchain, unlike Bitcoin and other similar currencies. So users looking to engage in some Decentraland mining will be disappointed. Instead, it was sold during token sales and is now being traded on exchanges.
