Two instances of the fetch-params.sh script running at once will result in corruption of the proving key and an error when the hashes are computed. This implements a lock to stop such a scenario from occurring. We also terminate and don't create the symlinks if the downloaded parameters fail the checksum command.

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 and anonymity through a sophisticiated zero-knowledge proving scheme which preserves confidentiality of transaction metadata.
Zcash is unfinished and highly experimental. Use at your own risk.
Participation in the Zcash project is subject to a Code of Conduct.
