It's mostly untested and isn't my best code, so run it on your own risk :)

1. Set up a Bitcoin XT testnet full node using testnet=1 in bitcoin.conf
2. You need to set up a postgresql database, then run a script from sql.sql
3. Update config.php with your settings
4. You need to run bootstrap.php to fill the database: /usr/bin/php bootstrap.php. That can take quite some time.
5. After this set up a cron service to run bootstrap.php every 10-20 minutes
6. You can see the results in index.php

If you want to analyze more than 1.000 blocks, you might want to change FIRST_BLOCK_TO_PROCESS constant in config.php
