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.

U Network is a revolutionary protocol for publishing and valuing online content that helps online content platforms better align with the interests of their users. It does this by rewarding content creators more for their work, by letting users earn money for predicting popular content, by making it easier to discover high-quality content, and by allowing all users to be part of content moderation and governance decisions. The first online content community powered by U Network will be U Community, a digital asset information community. In 2015, U Network team launches SV Insight, a Silicon Valley tech media company with over 4 million subscribers. In the year 2017, U Network team develops blockchain educational content together with Huobi, attracting over 30,000 paying users. Besides, U Network team launches a smart contract developers boot camp, training over 300 blockchain developers.
