# LBRYcrd - The LBRY blockchain


## What is LBRYcrd?

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.


## Development Process

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.

The contribution workflow is described in [CONTRIBUTING.md](CONTRIBUTING.md).


## Testing

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.

### Automated Testing

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`

There are also [regression and integration tests](/qa) of the RPC interface, written
in Python, that are run automatically on the build server.
These tests can be run (if the [test dependencies](/qa) are installed) with: `qa/pull-tester/rpc-tests.py`

The Travis CI system makes sure that every pull request is built for Windows
and Linux, OS X, and that unit and sanity tests are automatically run.

### Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the
code. This is especially important for large or high-risk changes. It is useful
to add a test plan to the pull request description if testing the changes is
not straightforward.
