A lightweight block explorer. Meant to be an improvement over Abe (hence the name). Design goals:

• Straightforward to setup with minimal dependencies
• Reasonable space consumption
• Clean, well written codebase for hackabilitiy.

Lincoln is still very much under development, so keep in mind that things may be a bit bumpy. Several key features are still missing!

• Python 3.2+
• Flask
• SQLAlchemy
• python-bitcoinlib
• Redis
• Gunicorn (although an WSGI server will work)

• Block reorgs aren't handled properly. A complete reindex is required.
• Sync status isn't shown, so the site may look oddly out of date if connection is lost or doing initial sync.
• There are no API endpoints, just a UI
• The address overview page is lacking a lot of information.

# Python 3.4 is highly preferred due to decimal support
mkvirtualenv lincoln --python /usr/bin/python3.4
pip install -r requirements.txt
pip install -e .

Now copy example.yml to config.yml and enter your RPC information.

# Initialize the database
python manage.py init_db
# To run the webserver
python manage.py runserver
# To sync the blockchain
python manage.py sync

To setup Lincoln on an Ubuntu box, follow these recommendations:

The chain sync chrontab should look something like this:

*/1 * * * * /usr/bin/flock -n /tmp/litecoin_scan.lockfile /path/to/my/virtualenv/bin/python /path/to/repo/manage.py sync >> /home/block/sync.log

An upstart config for the webserver would look something like this:

start on (filesystem)
stop on runlevel [016]

respawn
console log
setuid block
setgid block
chdir /home/block/lincoln

exec /home/block/lincoln_venv/bin/gunicorn lincoln.wsgi_entry:app -b 127.0.0.1:11000 --timeout 270
