Zcash (ZEC) is an innovative digital currency that is fast and confidential with low fees. It’s perfect for private mobile payments. Zcash relies on strong encryption and offers the highest level of privacy for shielded to shielded transactions. Zcash users are able to take advantage of a privacy set that grows over time. This is superior to coins that use mixing where the privacy set is limited to the number of transactions mixed together at a single moment in time.
– Low fees and on chain scaling
– Address and Transaction privacy
– Encrypted Memos (baked into all transactions)
– Viewing keys
– Payment disclosure
– Transaction expiration
– Multisignature transactions
Zcash is the first widespread application of zk-SNARKs, a novel form of zero-knowledge cryptography. The strong privacy guarantee of Zcash is derived from the fact that shielded transactions in Zcash can be fully encrypted on the blockchain, yet still be verified as valid under the network’s consensus rules by using zk-SNARK proofs.
The acronym zk-SNARK stands for “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge,” and refers to a proof construction where one can prove possession of certain information, e.g. a secret key, without revealing that information, and without any interaction between the prover and verifier.
“Zero-knowledge” proofs allow one party (the prover) to prove to another (the verifier) that a statement is true, without revealing any information beyond the validity of the statement itself. For example, given the hash of a random number, the prover could convince the verifier that there indeed exists a number with this hash value, without revealing what it is.
Trusted technology, growing adoption
Zcash was launched by one of the most respected technical teams in the world.
Zcash is the ‘https of blockchains,‘ protecting your freedom to save and spend as you like.
Zcash was the first project to implement zk-SNARKs, a novel form of zero-knowledge cryptography that gives its users the strongest privacy available in any digital currency.
Multiple, independent organizations are funded to innovate on Zcash.
