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.
Polymath simplifies the legal process of creating and selling security tokens. It makes a new token standard, the ST20, and enforces government compliance. Only a “list of authorized investors and their Ethereum wallet addresses” can hold ST20 tokens. Therefore, token issuers don’t need to worry about the legal implications of your security falling into the wrong hands. In order to launch a legally compliant token, the Polymath platform brings together issuers, legal delegates, smart contract developers, KYC verification, and a decentralized exchange. All transactions on the Polymath platform take place using the native POLY token. Polymath has programmable equity. Polymath enables companies to take control of their equity issuance through programmable code. It is raising in cryptocurrency opens up an entire wealth of new investors. Polymath eliminates the middleman and financial structures that hinder the deployment of equity. There is a trove of wealth that is untouched by Wall Street that can now be accessed through Polymath. In 2017, Polymath raised over $1.2 billion in funding by selling utility tokens and security tokens. Utility tokens, such as Waltonchain, give you access to a token’s network and are far more common than security tokens. Security tokens, however, provide equity or a claim to dividends from a company. As a result, security tokens, like any securities, are subject to government regulation. Polymath’s new standard for blockchain security tokens aims to embed the necessary regulatory requirements into smart contracts and comply entirely with government security regulations. A wide array of security tokens that will be listed on Polymath at some point will require investors to be accredited, or to be from specific countries.
