The relevant licenses are: * bdb: BDB (variant of Gnu Affero GPL) * libevent: BSD-3-clause * libsodium: ISC * tl_expected: CC0-1.0 * zeromq: LGPL-3+ with ZeroMQ exception In the case of zeromq, this is an explicit condition of the license -- specifically its static linking exception, which we rely on: "If you modify this library, you must extend this exception to your version of the library." In all cases, patches are necessarily derived (even if only trivially) from the code they are patching. We technically could relicense to MIT in some cases, but using the original license for patches we've written is a courtesy that makes it easier for upstream to adopt the patch, even if we don't specifically file a PR. native_cctools is also patched, but Debian copyright policy does not require `contrib/debian/copyright` to mention this dependency, because it is only part of the build process and its contents do not get compiled into the resulting build: https://www.debian.org/doc/debian-policy/ch-archive.html#s-pkgcopyright In all cases I checked that we have the right to distribute the patch under the relevant license (i.e. it doesn't depend on any incompatible third-party contributions). Reviewers should satisfy themselves of this. Signed-off-by: Daira Hopwood <daira@jacaranda.org> |

Zcash 5.4.0-rc4
What is Zcash?
Zcash is an implementation of the "Zerocash" protocol. Initially based on Bitcoin's design, 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 Protocol Specification.
The zcashd
Full Node
This repository hosts the zcashd
software, a Zcash consensus node
implementation. 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 several days.
The zcashd
code is derived from a source fork of
Bitcoin Core. The code was forked
initially from Bitcoin Core v0.11.2, and the two codebases have diverged
substantially.
🔒 Security Warnings
See important security warnings on the Security Information page.
Zcash is experimental and a work in progress. Use it at your own risk.
📒 Deprecation Policy
This release is considered deprecated 16 weeks after the release day. There 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 height.
Other Zcash Implementations
The Zebra project offers a different Zcash consensus node implementation, written largely from the ground up.
