Zcash is a privacy preserving digital currency and the first to use Zero Knowledge Proofs to obfuscate the identities of parties to a transaction. Zcash uses zk-SNARKs, a variant of Zero Knowledge Proofs, to prove that the conditions for a valid transaction have been met without revealing any crucial information about the addresses or values involved. Even though Zcash transactions require additional computation to be processed, the architecture of its blockchain guarantees a level of privacy that cannot be matched by other privacy-preserving technologies, including Monero’s Ring Signatures. The protocol known today as Zcash was initially developed under the name Zerocoin, a collaboration between researchers at Johns Hopkins University, a group of cryptographers at the Massachusetts Institute of Technology, students at the Israel Institute of Technology, and Tel Aviv University. The genesis block of Zcash was mined in October 2016.
