Zcash is a decentralized and open-source cryptocurrency that offers privacy and selective transparency of transactions. Zcash payments are published on a public blockchain, but the sender, recipient, and amount of a transaction remain private. Zcash is based on peer-reviewed cryptographic research, and built by a security-specialized engineering team on an open source platform based on Bitcoin Core's battle-tested codebase. Our improvement over Bitcoin is the addition of privacy. Zcash uses advanced cryptographic techniques, namely zero-knowledge proofs, to guarantee the validity of transactions without revealing additional information about them. How Zcash works Zcash encrypts the contents of shielded transactions. Since the payment information is encrypted, the protocol uses a novel cryptographic method to verify their validity. Zcash uses a zero-knowledge proof construction called a zk-SNARK, developed by our team of experienced cryptographers based on recent breakthroughs in cryptography. These constructions allow the network to maintain a secure ledger of balances without disclosing the parties or amounts involved. Instead of publicly demonstrating spend-authority and transaction values, the transaction metadata is encrypted and zk-SNARKs are used to prove that nobody is cheating or stealing. Zcash also enables users to send public payments which work similarly to Bitcoin. With the support for both shielded and transparent addresses, users can choose to send Zcash privately or publicly. Zcash payments sent from a shielded address to a transparent address reveal the received balance, while payments from a transparent address to a shielded address protect the receiving value.

BITKAN as an App serving cryptocurrency users and integrating market, information, mining monitoring and wallet, it provides four language versions, namely Chinese, English, Russian and Japanese. Now it has more than 5 million users from 170 countries around the world. BITKAN provides quotations and candlestick charts of more than 2,200 kinds of cryptocurrencies from more than 50 major cryptocurrency exchanges around the world. It has achieved News cooperation with more than 70 international media. The daily news updates are over 300, and the daily reads of the News section are over 500 thousand. BITKAN provides wallet services for digital asset transfer, such as BTC, BCH, DASH, ETH, SAFE, and it has provided stable and secure wallet service for the assets of 170,000 users. The team will launch the first blockchain-concentrated community around the blockchain industry based on the BITKAN platform: K Site. The community will encourage users to produce high-quality contents, and users can get profits in the form of cryptocurrencies by publishing high-quality contents. The communities created by users in the community will be presented in the form of 'K Site'. The creators can set up the 'K Site' to pay for admission or join for free. By composing high-quality contents, it can attract other users to join in and form their own 'K Sites'. Users having joined in can read the contents of the 'circle' or post their own content in the 'circle'. On the other hand, users can also set a certain content for paid reading, the more people who read, the greater the income. Users can also reward the content to encourage the author to continue to compose more and better content. KAN will be used to pay for the platform services of BITKAN. If a user keeps sufficient amount of KAN will enjoy a certain percentage discount for service fees, and service fees will be deducted from KAN. The main project team comes from BITKAN, which currently provides price monitoring, news and information, mining monitoring, wallet and other services for cryptocurrencies. Users can store cryptocurrencies simply, conveniently and safely through the BITKAN app. At the same time, they can check the market price of cryptocurrencies of major exchanges in real time, get timely and fresh industry information at home and abroad, and set up price reminders by BITKAN app. And it has real-time mining monitoring, which allows you to master the running condition of the mining machine whenever and wherever possible. The token is called 'KAN'. A strict limit of 10 billion KAN will be issued, and will never be increased. KAN will be issued according to the Ethereum ERC 20 standard. KAN's profit comes mainly from the payment fees, exchange fees and membership service fees from the BITKAN platform. BITKAN is already online. The team is currently developing the 'K Site' feature which is a decentralized crytocurrency-concentrated & content payment community. KAN will be online as the same time as the 'K Site' feature, which is scheduled in May 2018.
