WHAT IS ZCASH?
offers total payment confidentiality, while still maintaining a
decentralized network using a public blockchain. Unlike Bitcoin, Zcash
transactions automatically hide the sender, recipient, and value of all
transactions on the blockchain. Only those with the correct view key can
see the contents. Users have complete control and can opt-in to provide
others with their view key at their discretion.
Zcash transactions do not depend on the cooperation of other parties.
HOW DOES IT WORK?
the contents of Zcash transactions are encrypted and private, the
system uses a novel cryptographic method to verify payments.
uses a zero-knowledge proof construction called a zk-SNARK, developed
by our team of experienced cryptographers. 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

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.

The Zcash company aims to set a new standard for privacy through the use of groundbreaking cryptography.
an open and programmable financial system, privacy is the only way to
ensure fungibility and guarantee that cryptocurrency can be
interchangeable as a fluid medium of exchange for users. Companies need
the protection of privacy along their supply chain in order to conduct
their business, especially in the context of public blockchains. In
addition, we believe that personal privacy is necessary for core human
values like dignity, intimacy, and morality.
We are a
science-driven team. Our scientists and engineers are the discoverers of
the underlying scientific principles and the designers of the protocol;
we are not the controllers or the power-holders, and do not control the
mining or distribution of Zcash. Every user of Zcash contributes to its
decentralization, helping to protect it against failure and corruption.
Our team is one among many participants in the network. We created
Zcash, but its ultimate destiny lies not in our hands, but in yours.
