fixes #6518 In a ZIP sync meeting we decided that: * The minimum cost should be changed to 10000, in order to avoid penalizing Orchard-using transactions too much relative to other transactions. * `low_fee_penalty` should be changed to 40000. This preserves the property that a transaction paying less than the ZIP 317 conventional fee is deprioritized relative to a min-cost, conventional-fee transaction by a factor of 5, as in the original design. * The recommended default for `mempooltxcostlimit` should remain at 80000000. Rationale: 80000000 was chosen so that the worst-case size of the mempool would be equal to the worst-case size of 40 blocks, which is the current default transaction expiry delta. That reasoning still holds even with the above changes. * `eviction_memory_entries` remains at 40000. It could have been lowered given that there will now be at most 80000000/10000 = 8000 transactions "in-flight", but it doesn't need to be because the rationale that "40000 [RecentlyEvicted queue] entries can be stored in ~1.6 MB, which is small compared to other node memory usage" still holds.

Zcash 5.4.2
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.

Building
Build Zcash along with most dependencies from source by running the following command:
./zcutil/build.sh -j$(nproc)
Currently, Zcash is only officially supported on Debian and Ubuntu. See the Debian / Ubuntu build for detailed instructions.
