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.

Content: We hope to, basing on the technology of block chain, adopting unique non-tamper distributed ledger characteristics of the block chain, build the traceability cloud platform, solve the enterprise's difficulties in information traceability, anti-counterfeit, verification and mobile marketing during commodity production, circulation and distribution and terminal consumption process through the sub-chain of the landing project and corresponding DAPP application, and provide a fast and efficient cluster of cloud services development for the technical developers, so as to solve the problem of 'trusted' for brand enterprises and consumers, and then build a new block chain ecosystem ---Traceability Chain as the future world-selectable internet value transmission protocol, and push forward the practicability and usability of the whole block chain industry. As the most promising block chain ecosystem, it perfectly combines the advantages of Ethereum and Bitshares. Traceability Chain will also constantly and gradually form the block chain economy through the construction of the foundation platform, the design and development of the software and hardware products, the development of various products and the development and iteration of the commercial landing project, improve the industry efficiency, and promote the effective and collaborative development of the society.
