The Parity Bitcoin client
Installing from source
Installing pbtc
from source requires rustc
and cargo
.
Minimal supported version is rustc 1.16.0 (30cf806ef 2017-03-10)
Install rustc and cargo
Both rustc
and cargo
are a part of rust toolchain.
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 repo is already cloned, we can run unit tests with this command:
./tools/test.sh
Running external integration tests
Running integration tests is automated, as regtests repo 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 --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
To start syncing the mainnet, just start the client
./target/release/pbtc
To start syncing the testnet
./target/release/pbtc --testnet
To print syncing progress add --print-to-console
flag
./target/release/pbtc --print-to-console
Importing bitcoind database
It it is possible to import existing bitcoind database:
# where $BITCOIND_DB is path to your bitcoind database eg. "/Users/marek/Library/Application Support"
./target/release/pbtc --print-to-console import "$BITCOIND_DB/Bitcoin/blocks"
By default import verifies imported the blocks. You can disable this, by adding `--skip-verification flag.
./target/release/pbtc --print-to-console import "#BITCOIND_DB/Bitcoin/blocks" --skip-verification

-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).

TODO
Logging
This is a section only for dev / power users.
You can enable detailed client logging by setting env variable RUST_LOG
eg.
RUST_LOG=verification=info ./target/release/pbtc
pbtc
started with this env variable will print all logs comming from verification
module with verbosity info
or higher
Available log levels:
error
warn
info
debug
trace
It's also possible to start logging from multiple modules in the same time
RUST_LOG=sync=trace,p2p=trace,verification=trace,db=trace
note RUST_LOG
does not work together with command line option --print-to-console
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
