Zebra Utilities

This crate contains tools for zebra mantainers.

Binaries are easier to use if they are located in your system execution path.

zebra-checkpoints

This software will output a list of zcash block hashes that are used as zebra checkpoints. To create checkpoints a synchronized instance of zcashd is needed and a zcash-cli wallet connected to it must be available locally. For more information about how to create a checkpoint list please check here

This is a standalone rust binary, can be compiled as:

cargo build --release --bin zebra-checkpoints

After built check the program help with:

./target/release/zebra-checkpoints --help

zebrad-hash-lookup

Given a block hash the script will get additional information using zcash-cli.

$ echo "00000001f53a5e284393dfecf2a2405f62c07e2503047a28e2d1b6e76b25f863" | zebrad-hash-lookup

$

This program is commonly used as part of zebrad-log-filter where hashes will be captured from zebrad output.

zebrad-log-filter

The program is designed to filter the output from the zebra terminal or log file. Each time a hash is seen the script will capture it and get the additional information using zebrad-hash-lookup.

Assuming zebrad, zclash-cli, zebrad-hash-lookup and zebrad-log-filter are in your path the program can used as:

$ zebrad -v start | zebrad-log-filter
