# LBRYcrd - The LBRY blockchain
|
|
|
|
|
|
|
|
LBRYcrd uses a blockchain similar to bitcoin's to implement an index and payment system for content on the LBRY network. It is a fork of bitcoin core.
|
|
|
|
## Installation
|
|
|
|
Latest binaries are available from https://github.com/lbryio/lbrycrd/releases. There is no installation procedure, the binaries will be run as-is.
|
|
|
|
## Usage
|
|
|
|
The `lbrycrdd` executable will start a LBRYcrd node and connect you to the LBRYcrd network. Use the `lbrycrd-cli` executable
|
|
to interact with lbrycrdd through the command line. Help pages for both executable are available through
|
|
the "--help" flag (e.g. `lbrycrd-cli --help`).
|
|
|
|
### Example Usage
|
|
|
|
Run `./lbrycrdd -server -daemon` to start lbrycrdd in the background.
|
|
|
|
Run `./lbrycrd-cli getinfo` to check for some basic information about your LBRYcrd node.
|
|
|
|
Run `./lbrycrd-cli help` to get a list of all commands that you can run. To get help on specific commands run `./lbrycrd-cli [command_name] help`
|
|
|
|
### Data directory
|
|
|
|
Lbrycrdd will use the below default data directories:
|
|
|
|
Windows < Vista: C:\Documents and Settings\Username\Application Data\lbrycrd
|
|
|
|
Windows >= Vista: C:\Users\Username\AppData\Roaming\lbrycrd
|
|
|
|
Mac: ~/Library/Application Support/lbrycrd
|
|
|
|
Unix: ~/.lbrycrd
|
|
|
|
The data directory contains various things such as your default wallet (wallet.dat), debug logs (debug.log), and blockchain data. You can optionally create a configuration file lbrycrd.conf in the default data directory which will be used by default when running lbrycrdd.
|
|
|
|
For a list of configuration parameters, run `./lbrycrdd --help`. Below is a sample lbrycrd.conf to enable JSON RPC server on lbrycrdd.
|
|
|
|
```
|
|
rpcuser=lbry
|
|
rpcpassword=xyz123456790
|
|
daemon=1
|
|
server=1
|
|
txindex=1
|
|
```
|
|
|
|
## Running from Source
|
|
|
|
Run `./reproducible_build.sh -c -t`. This will build the binaries and put them into the `./src` directory.
|
|
|
|
If you encounter any errors, please check `doc/build-*.md` for further instructions. If you're still stuck, [create an issue](https://github.com/lbryio/lbrycrd/issues/new) with the output of that command, your system info, and any other information you think might be helpful.

## Contributing
|
|
|
|
Contributions to this project are welcome, encouraged, and compensated. For more details, see [lbry.io/faq/contributing](https://lbry.io/faq/contributing)
|
|
|
|
We follow the same coding guidelines as documented by Bitcoin Core, see [here](/doc/developer-notes.md). To run an automated code formatting check, try:
|
|
`git diff -U0 master -- '*.h' '*.cpp' | ./contrib/devtools/clang-format-diff.py -p1`. This will check any commits not on master for proper code formatting.
|
|
We try to avoid altering parts of the code that is inherited from Bitcoin Core unless absolutely necessary. This will make it easier to merge changes from Bitcoin Core. If commits are expected not to be merged upstream (i.e. we broke up a commit from Bitcoin Core in order to use a single feature in it), the commit message must contain the string "NOT FOR UPSTREAM MERGE".
|
|
|
|
The `master` branch is regularly built and tested, but is not guaranteed to be
|
|
completely stable. [Releases](https://github.com/lbryio/lbrycrd/releases) are created
|
|
regularly to indicate new official, stable release versions.
|
|
|
|
Testing and code review is the bottleneck for development; we get more pull
|
|
requests than we can review and test on short notice. Please be patient and help out by testing
|
|
other people's pull requests, and remember this is a security-critical project where any mistake might cost people
|
|
lots of money. Developers are strongly encouraged to write [unit tests](/doc/unit-tests.md) for new code, and to
|
|
submit new unit tests for old code. Unit tests can be compiled and run
|
|
(assuming they weren't disabled in configure) with: `make check`
|
|
|
|
The Travis CI system makes sure that every pull request is built, and that unit and sanity tests are automatically run.
|
|
|
|
### Testnet
|
|
|
|
Testnet is maintained for testing purposes and can be accessed using the command `./lbrycrdd -testnet`. If you would like to obtain testnet credits, please contact brannon@lbry.io or grin@lbry.io.
