Hcash is a new cryptocurrency designed to allow value transfer among blockchains and between blockchains and blockless cryptocurrencies. In addition, Hcash will support private transactions, DAO governance, and quantum resistance. Since Hcash hopes to be a side chain for many different cryptocurrencies, including privacy coins, it will need to implement privacy features to mask how users are moving their funds. To address this issue, Hcash will come with two types of wallets: white and black. While the white addresses will be publicly viewable, the black addresses will remain private. In order to achieve this privacy, Hcash will implement zero-knowledge proofs. This system, as proven on Zcash’s blockchain, involves masking the identity of the sender and receiver through the use of advanced cryptography to verify transactions without sharing information about the transaction with miners. As a result, blockchains that implement zero-knowledge proofs do not include any identifiable user information. Hshare offers enormous technical potential in the industrial, private network sector. Multi-compatible and multifunctional software, which is already designed for quantum processors, makes it possible to combine a wide variety of crypto technologies. This offers advantages in the FinTech area, in finance, in dealing with Big Data and also for the application area of the Internet of Things. Hshare seems to be not subject to any limitations.
Quasar Coin 'Fair travel' is also referred to as 'good travel' as a concept derived from fair trade, in which producers and consumers form a comparable relationship. It has been promoted in European and other English-speaking countries since the 2000s to reflect the environmental pollution, destruction of civilization and waste caused by the trips, and to give a little help to the residents of difficult countries. We want to build a platform in which travelers, hotels, restaurants and stores around the world can mutually satisfy each other through fair trade. Technically, we have built up an advanced reputation system based on a block chain, a simple payment system in the form of a credit card, various APIs, an instant transaction system to minimize the variability of cryptocurrency, In business, it provides discounts through discounted quasar cards and eliminates anxiety factors by using proven companies, and provides companies with promotional effects and sales increase within the Quasar platform. Quasar Coin has adopted the bit coin platform, which has been proven to be safe as the first cryptocurrency, and applied Light Coin to reduce block time for quick settlement in daily transactions. In addition, for smooth block mining, it solves the difficulty-bomb problem which intentionally raises difficulty to make it difficult to mine. Since the development of the quasar coin has already been completed, the project team has focused on the development of the related infrastructure system in order to activate the transaction of the cryptocurrency. Quasar Card Quasar cards are the easiest payment method for users who are familiar with using credit cards when paying by quasar coin, and can be paid by various methods such as QR code, IC chip and NFC according to the status of the receiving terminal of the company. By combining the unique hash codes given by the system when issuing the card based on the public key, illegal settlement is prevented so that it can only be used with the public key Smart Wallet In general, mobile wallet offers three basic functions, sending coins, receiving coins and transaction records.
