This python script (node.py) is a client node for the bitcoin network.

It is based on ArtForz' half-a-node at http://pastebin.com/ZSM7iHZw

In its current form, node.py does nothing more than listen for new

transactions and blocks, perform some simple verification checks on

the data, and store them in a database. It does not handle script

verification or chain reorg, and is therefore not safe for general use.

It might be useful as the base for a P2P monitoring node, or similar

tasks.

Command line usage:

./node.py my-config-file

The configuration file is a key=value text file, with the following settings:

# hostname or IP address of network node to connect to

host=127.0.0.1

# port of network node to connect to (default: 8333)

port=8333

# database directory

db=/tmp/chaindb

# log filename, or '-' or no-value for standard output

log=/tmp/chaindb/node.log

# if present, import these blocks into the block database

loadblock=/tmp/blk0001.dat

node.py connects to a single remote node, and does not accept incoming

P2P connections. If the connection is lost, node.py exits.
