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.

CoinPoker is a worldwide cryptocurrency-based online poker room that’s launching its ICO this November. We’re operating with Ethereum Smart Contracts and once the room will have been launched, we’re going to ensure full transparency via the use of blockchains. The RNG will be visible on blockchains, and the players will be able to see it after the game. That together with the pain-free transactions thanks to cryptocurrency will solve many of the problems that online poker has been facing. • Transactions will be immediate + accessible worldwide; • RnG will be visible for transparency; • Anonymity will be guaranteed; • Fair play at the tables will be ensured. + HUGE Grand Opening Events with awesome prizes (15% of tokens distributed during the ICO will be returned during these tournaments). What makes us different from other ICOs? Well, for one, we’ve got our MVP (minimum viable product, in our case – an app) ready to go, and we’ll be launching our MVP with play money before our actual ICO start!
