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.

Utilizing a community of world-class developers, managers, marketers and researchers, the Apollo community, backed by the Apollo Foundation, has set out to accomplish the goal of making Apollo the most technologically advanced, feature-rich currency on the market. The Apollo Foundation understands the demands of a top tier cryptocurrency and they believe they can create a coin that will integrate everything necessary to replace the current currency options. Having started from NXT, a proven cryptocurrency, the Apollo Foundation will continue development with the goal of being first all-in-one cryptocurrency, innovating and incorporating every ability that could be beneficial in a digital currency, all in a single decentralized platform. The first major update, Olympus Protocol, puts mass adoption-proof privacy at Apollo's core. This is because the Apollo Foundation knows the ability for a user to buy, sell, trade and send in absolute secrecy is vital in an industry that could be moments away from intense regulation. The Apollo team is here because they believe the only person or entity that should be in control of your funds is you.
