Crypto.com, the pioneering payments and cryptocurrency platform, seeks to accelerate the world’s transition to cryptocurrency. The MCO Token Sale was conducted in May-June 2017 and raised US$26.7 million. MCO Card is a Visa-branded debit card that draws from a cryptocurrency-funded bank account. Since it’s a Visa card, you can use your MCO Visa card just like you would any other card. The card and bank account are free for holders of cryptocurrency. In order to open an account, you simply sign up, verify your identity, and transfer any of the various accepted cryptocurrencies to your account. At this time, the Visa card is available to customers in Asia. They also have a waitlist for European customers. Customers in the United States does not have access to it at the moment. However, there are plans to change that. Solving the problem of everyday payments has the potential to be huge for cryptocurrency. However, MCO Visa card is not the only project attempting to create crypto-backed debit (or prepaid) cards. Other projects, such as TenX, are working on the same issue. All of these projects run into challenges implementing such cards in a large scale, compliant manner. Crypto.com hopes to crack the code, ultimately getting cryptocurrencies and popular payment methods to play nicely together. Crypto.com was founded in June 2016 in Switzerland and rebranded from Monaco on 6th July 2018. Their first prototype was developed in October of that year. In February of 2017, they were accepted into a Hong Kong Government backed Cyberport incubation program, where they developed their platform until they were ready to launch their token sale in 2017. The sale closed in June with $26.7 million in funding. Their app became available to pre-registered users in August 2017, followed by the official partnership with Visa in October. The team consists of seasoned veterans in the fin-tech space, most of whom have experience in Asia, where Monaco Cards have first been made available. Since MCO Visa cards are backed by cryptocurrency, they don’t have border issues like fiat currencies. As a result, you can use your card anywhere you go. The card will automatically default to the local fiat currency when you make a purchase. The low fees and exchange rates also apply in other countries. Transactions take place at the exact exchange rate that Crypto.com receives as an institutional trader. In contrast, when you use your debit card across borders with most banks, they’ll add an additional percentage to the exchange rate or include a transaction fee. Crypto.com has connections with eight of the top ten international foreign exchange banks to facilitate currency conversion. The MCO Visa card is a compelling option for anyone looking to make everyday purchases with cryptocurrency. It also makes sense for cross-border travelers. However, we can expect the rollout to take a long time and hit a lot of bumps along the way. The financial industry is highly regulated and cryptocurrency-backed payments is a complex issue, even if Crypto.com's solution seems to make it simple and user-friendly.
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.
