A privacy-focused cryptocurrency that uses zero-knowledge proofs to enable shielded transactions with full anonymity.
Zcash is a privacy-focused cryptocurrency that enables anonymous transactions using zero-knowledge proofs. It solves the transparency problem of traditional cryptocurrencies like Bitcoin by allowing users to shield transaction details while still operating on a public blockchain. The project provides a full node implementation called `zcashd` for participating in the network.
Cryptocurrency users, privacy advocates, and developers interested in anonymous digital payments or blockchain privacy technologies.
Developers choose Zcash for its strong privacy guarantees through zk-SNARKs, offering a level of anonymity not available in most cryptocurrencies. It provides a practical implementation of advanced cryptography for real-world financial privacy.

Uses zk-SNARKs to encrypt transaction amounts and participants, providing full anonymity, as detailed in the Protocol Specification and README's description of shielded transactions.
Offers both transparent and shielded transactions, allowing users to choose between Bitcoin-like visibility and enhanced privacy, as highlighted in the Key Features.
Operates on a proof-of-work blockchain, ensuring security without central authorities, similar to Bitcoin's model from which it was forked.
The `zcashd` software enables running a full node to validate and store the entire transaction history, supporting network participation as described in the README.
Synchronizing the blockchain can take several days depending on hardware and network, making it impractical for quick setup, as warned in the README.
Officially supported only on Debian and Ubuntu, restricting deployment on other platforms like Windows or macOS, as stated in the building instructions.
Releases are deprecated after 16 weeks with an automatic shutdown feature, requiring regular updates and adding maintenance overhead, per the Deprecation Policy.
Described as experimental and a work in progress, posing potential risks for production use, as noted in the Security Warnings section.
