Zcash is an implementation of the Decentralized Anonymous Payment scheme Zerocash, with security fixes and adjustments to terminology, functionality and performance. It bridges the existing transparent payment scheme used by Bitcoin with a shielded payment scheme secured by zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs). It attempts to address the problem of mining centralization by use of the Equihash memory-hard proof-of-work algorithm. This specification defines the Zcash consensus protocol and explains its differences from Zerocash and Bitcoin.
Shielded Zcash transactions are completely private.
Like Bitcoin, Zcash transaction data is posted to a public blockchain; but unlike Bitcoin, Zcash ensures your personal and transaction data remain completely confidential. Zero-knowledge proofs allow transactions to be verified without revealing the sender, receiver or transaction amount. Selective disclosure features within Zcash allow a user to share some transaction details, for purposes of compliance or audit.
Zcash also allows for transparent transactions, to accommodate for wallets and exchanges that don’t support private transactions.
