[C] Coins information

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. Our zero-knowledge proving scheme makes it possible to conceal values and other identifying information from the public blockchain. Users simply prove that the values balance out and that they are not double-spending the amount they want to send. https://z.cash/ https://chat.zcashcommunity.com https://forum.z.cash/
