There was a race condition here between the block generated by node 0 being broadcast to node 1, and being invalidated by node 0. Due to the changes we made to the difficulty adjustment algorithm, the invalidated block and the block replacing it generated by node 0 would have the same chain work; thus if node 1 observed the invalidated block, it would never reorg to the replacement block. We fix this by having node 0 reconsider the invalidated block before generating its next block. This avoids the chain fork, and also clears the mempool to provide better separation between test stages. Co-authored-by: Daira Hopwood <daira@jacaranda.org> |

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.
