Write witness caches when writing the best block For steady-state operation, this reduces the average time between wallet disk writes from once per block to once per hour. On -rescan, witness caches are only written out at the end along with the best block, increasing speed while ensuring that on-disk state is kept consistent. Witness caches are now never recreated during a -reindex, on the assumption that the blocks themselves are not changing (the chain is just being reconstructed), and so the witnesses will remain valid. Part of #1749.
Zcash 1.0.3
What is Zcash?
Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Technical details are available in our Protocol Specification.
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.
Security Warnings
