BigchainDB block plugin example

This repo contains a minimal implementation of a plugin for BigchainDB. It listens to blocks and print the id of the block to the console.

It can be used as a baseline to publish the newly created blocks to different services, like RabbitMQ.

Usage

Clone this repository and install the module:

$ pip install -e .

The module must be visible by BigchainDB. You can install it globally (you might need to use sudo) or in a virtual env.

Then, add the plugin to your .bigchaindb configuration:

{
    "server": { ... },
    "wsserver": { ... },
    ...
    "events_plugins": ["console_print"]
    ...
}

You can now run BigchainDB:

$ bigchaindb start

The log should display something like:

[2017-07-31 02:36:10] [INFO] (bigchaindb.processes) Loading block publisher plugin console_print (MainProcess - pid: 27894)
