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.
PAX Gold (PAXG) is an asset-backed token where one token represents one fine troy ounce of a London Good Delivery gold bar, stored in professional vault facilities. Anyone who owns PAXG has ownership rights to that gold under the custody of Paxos Trust Company. Since PAXG represents physical gold, its value is tied directly to the real-time market value of that physical gold. PAXG gives customers the benefits of actual physical ownership of specific gold bars with the speed and mobility of a digital asset. Customers are able to have fractional ownership of physical bars. On the Paxos platform, customers can convert their tokens to allocated gold, unallocated gold, or fiat currency (and vice versa) quickly and efficiently, reducing their exposure to settlement risk. PAXG is also available for trading on Paxos’ itBit exchange. PAXG will also be available on other crypto-asset exchanges, wallets, lending platforms and elsewhere within the crypto ecosystem. At any time, PAXG holders can lookup the serial number, value and physical characteristics of their vaulted gold just by entering their Ethereum wallet address on the PAXG lookup tool on Paxos.com/paxgold.
