Installing pbtc from source requires rustc and cargo.
Minimal supported version is rustc 1.23.0 (766bd11c8 2018-01-01)
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.
You will need the cc and gcc compilers to build some of the dependencies.
sudo apt-get update sudo apt-get install build-essential 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.
In any of the supported Linux distros:
sudo snap install parity-bitcoin --edge pbtc has internal unit tests and it conforms to external integration tests.
Assuming that repository is already cloned, we can run unit tests with this command:
cargo test --all 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 using the command:
./tools/regtests.sh It is 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 By default parity connects to bitcoind-seednodes. Full list is available 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 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 --btc --verification-level=none import "$BITCOIND_DB/Bitcoin/blocks" Full list of CLI options, which is available under pbtc --help:
pbtc 0.1.0 Parity Technologies <info@parity.io> Parity Bitcoin client USAGE: pbtc [FLAGS] [OPTIONS] [SUBCOMMAND] FLAGS: --bch Use Bitcoin Cash verification rules (BCH). --btc Use Bitcoin Core verification rules (BTC). -h, --help Prints help information --no-jsonrpc Disable the JSON-RPC API server. -q, --quiet Do not show any synchronization information in the console. --regtest Use a private network for regression tests. --testnet Use the test network (Testnet3). -V, --version Prints version information OPTIONS: --blocknotify <COMMAND> Execute COMMAND when the best block changes (%s in COMMAND is replaced by the block hash). -c, --connect <IP> Connect only to the specified node. -d, --data-dir <PATH> Specify the database and configuration directory PATH. --db-cache <SIZE> Sets the database cache size. --jsonrpc-apis <APIS> Specify the APIs available through the JSONRPC interface. APIS is a comma-delimited list of API names. --jsonrpc-cors <URL> Specify CORS header for JSON-RPC API responses. --jsonrpc-hosts <HOSTS> List of allowed Host header values. --jsonrpc-interface <INTERFACE> The hostname portion of the JSONRPC API server. --jsonrpc-port <PORT> Specify the PORT for the JSONRPC API server. --only-net <NET> Only connect to nodes in network version <NET> (ipv4 or ipv6). --port <PORT> Listen for connections on PORT. -s, --seednode <IP> Connect to a seed-node to retrieve peer addresses, and disconnect. --verification-edge <BLOCK> Non-default verification-level is applied until a block with given hash is met. --verification-level <LEVEL> Sets the Blocks verification level to full (default), header (scripts are not verified), or none (no verification at all). SUBCOMMANDS: help Prints this message or the help of the given subcommand(s) import Import blocks from a Bitcoin Core database. rollback Rollback the database to given canonical-chain block. The JSON-RPC interface is served on port :8332 for mainnet and :18332 for testnet unless you specified otherwise. So if you are using testnet, you will need to change the port in the sample curl requests shown below.

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 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
