< p > < a href = "https://z.cash/" > Zcash< / a > is an implementation of the " Zerocash" protocol.
Based on Bitcoin's code, Zcash intends to offer a far higher standard of privacy
through a sophisticated zero-knowledge proving scheme that preserves
confidentiality of transaction metadata. More technical details are available
in our < a href = "https://zips.z.cash/protocol/protocol.pdf" > Protocol Specification< / a > .< / p >
< p > This software is the Zcash client. It downloads and stores the entire history
of Zcash transactions; depending on the speed of your computer and network
connection, the synchronization process could take a day or more once the
blockchain has reached a significant size.< / p >

is an automatic deprecation shutdown feature which will halt the node some
time after this 16-week period. The automatic feature is based on block
