Pundi X is the project that wants to make spending crypto as easy as a credit card. Creators of the NPXS token hope that it will one day be used on their Ethereum-based Point-of-Sale devices. This approach could give basic banking services to underdeveloped regions like Latin America and Indonesia. One of the most notorious pain points in crypto is the ability to actually make purchases. Pundi X cryptocurrency plans to change all that by distributing hundreds to thousands of point-of-sale smart devices to retailers so they can accept payment in the form of NPXS, the network’s proprietary crypto token. If it can distribute the devices for free and with lower transaction fees than current card and mobile payment solutions provide, it’s a grand-slam idea. Pundi X raised $35 million during its ICO from September 2017 through January 21, 2018. 35,000,000,000 NPXS (at the time known as PXS) were sold during the ICO presale and crowd sale. The team retained 15,750,000 and another 1,750,000,000 was distributed to early investors and the rest was held by Pundi X for further development and marketing. It also set aside 2 percent of sold tokens to fund bounty programs across social media and online platforms. The Pundi X team are a talented group of technologists and entrepreneurs, which seems to be exactly what this project will need for success. In general the management team is comprised of computer engineers turned serial entrepreneur. The glaring exception to this is CEO and founder Zac Cheah, who was formerly an HTML games developer, but perhaps this is why he surrounded himself with such a strong team. The President of Pundi X, Constantin Papadimitrou, has a long history of founding successful fintech companies, and scaling them, which makes him an ideal fit for a project that will need rapid growth and adoption. The CTO/COO Pitt Huang created and sold his first business by the age of 25 and went on to create and sell several more business, including one that had over 200 employees. The company is working on developing a card, which they are naming the XPASS card, which will work together with the mobile app and wallet, enabling payments and deposits by card (a familiar medium for most) that are pulled from the mobile wallet. In addition, users should be able to see the current market price of each cryptocurrency before paying for goods and services, allowing them to pay with the cryptocurrency that brings the best value at the time. This ability to pay for things easily with cryptocurrencies is what will finally give them real value in a widespread sense. Pundi X has taken on an impressive and ambitious task in tackling what could amount to everyday adoption of cryptocurrencies by the masses, if their vision is realized. The technology seems appropriate for what they’re attempting, and the delivery of the first 500 POS devices shows that there is substance behind their efforts.'
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.
