Once this command runs, it will download around 911 MBs of keys into the ~/.zcash-params/ directory.
The directory contains files for proving and verifying keys: $ pwd /home/drequinox/.zcash-params $ ls -ltr sprout-verifying.key sprout-proving.key 5.
Bringing Zero-Knowledge Privacy to Smart Contract Platforms (Part 2)
Once the preceding commands are completed successfully, the source code can be built using the following command: $ ./zcutil/build.sh -j$(nproc) This will produce a very long output; if everything goes well it will produce a zcashd binary file.
Note that this command takes nproc as the parameter, which is basically a command that finds the number of cores or processors in the system and displays that number.
If you don’t have that command then replace nproc with the number of processors in your system.
Once the build is completed, the next step is to configure Zcash.
This is achieved by creating a configuration file with the name zcash.conf in the ~/.zcash/ directory.
A sample configuration file is shown as follows: addnode=mainnet.z.cash rpcuser=drequinox rpcpassword=xxxxxxoJNo4o5c+F6E+J4P2C1D5izlzIKPZJhTzdW5A= gen=1 genproclimit=8
