Installing from source
Installing pbtc from source requires rustc and cargo.
Minimal supported version is rustc 1.23.0 (766bd11c8 2018-01-01)
Install rustc and cargo
Both rustc and cargo are a part of rust tool-chain.
An easy way to install the stable binaries for Linux and Mac is to run this in your shell:
curl -sSf https://static.rust-lang.org/rustup.sh | sh
Windows binaries can be downloaded from rust-lang website.
Install C and C++ compilers
You will need the cc and gcc compilers to build some of the dependencies.
sudo apt-get update
sudo apt-get install build-essential
Clone and build pbtc
Now let's clone pbtc and enter it's directory:
git clone https://github.com/paritytech/parity-bitcoin
cd parity-bitcoin
pbtc can be build in two modes. --debug and --release. Debug is the default.
# builds pbtc in debug mode
cargo build -p pbtc
# builds pbtc in release mode
cargo build -p pbtc --release
pbtc is now available at either ./target/debug/pbtc or ./target/release/pbtc.
Installing the snap
In any of the supported Linux distros:
sudo snap install parity-bitcoin --edge
Running tests
pbtc has internal unit tests and it conforms to external integration tests.
Running unit tests
Assuming that repository is already cloned, we can run unit tests with this command:
cargo test --all
Running external integration tests
Running integration tests is automated, as the regtests repository is one of the submodules. Let's download it first:
git submodule update --init
Now we can run them:
./tools/regtests.sh
It's also possible to run regtests manually:
# let's start pbtc in regtest compatible mode
./target/release/pbtc --btc --regtest
# now in second shell window
cd $HOME
git clone https://github.com/TheBlueMatt/test-scripts
cd test-scripts
java -jar pull-tests-f56eec3.jar
Going online
By default parity connects to bitcoind-seednodes. Full list is here.
Before starting synchronization, you must decide - which fork to follow - Bitcoin Core (--btc flag) or Bitcoin Cash (--bch flag). On next start, passing the same flag is optional, as the database is already bound to selected fork and won't be synchronized using other verification rules.
To start syncing the main network, just start the client, passing selected fork flag. For example:
./target/release/pbtc --btc
To start syncing the testnet:
./target/release/pbtc --btc --testnet
To not print any syncing progress add --quiet flag:
./target/release/pbtc --btc --quiet
Importing bitcoind database
It it is possible to import existing bitcoind database:
# where $BITCOIND_DB is path to your bitcoind database, e.g., "/Users/user/Library/Application Support"
./target/release/pbtc import "$BITCOIND_DB/Bitcoin/blocks"
By default import verifies imported the blocks. You can disable this, by adding --verification-level==none flag.
./target/release/pbtc import "#BITCOIND_DB/Bitcoin/blocks" --btc --skip-verification

Logging
This is a section only for developers and power users.
You can enable detailed client logging by setting the environment variable RUST_LOG, e.g.,
RUST_LOG=verification=info ./target/release/pbtc --btc
pbtc started with this environment variable will print all logs coming from verification module with verbosity info or higher. Available log levels are:
errorwarninfodebugtrace
It's also possible to start logging from multiple modules in the same time:
RUST_LOG=sync=trace,p2p=trace,verification=trace,db=trace ./target/release/pbtc --btc
Internal documentation
Once released, pbtc documentation will be available here. Meanwhile it's only possible to build it locally:
cd parity-bitcoin
./tools/doc.sh
open target/doc/pbtc/index.html
