================ slick-bitcoinrpc

Just another Python bitcoin-rpc client. Built as faster alternative to python-bitcoinlib rpc (https://github.com/petertodd/python-bitcoinlib) and python-bitcoinrpc (https://github.com/jgarzik/python-bitcoinrpc) using pycurl and ujson.

Installation

pip install slick-bitcoinrpc

Example

.. code:: python

from slickrpc import Proxy

bitcoin = Proxy("http://%s:%s@127.0.0.1:8332"%(rpcuser, rpcpassword))
print(bitcoin.getblock(bitcoin.getbestblockhash()))

Performance Comparison

Method

Here's bash script able to measure performance of such bitcoin rpc clients

.. code:: bash

RPC_URL='http://username:password@127.0.0.1:8332'
TASKS=(
  "p.getinfo()"
  "p.getblock(p.getbestblockhash())"
  "map(lambda tx: p.getrawtransaction(tx['txid'], 1), p.listtransactions())"
)
SETUPS=(
  "from slickrpc import Proxy; p = Proxy(service_url='$RPC_URL');"
  "from bitcoinrpc.authproxy import AuthServiceProxy; p = AuthServiceProxy(service_url='$RPC_URL');"
  "from bitcoin.rpc import Proxy; p = Proxy(service_url='$RPC_URL');"
)
for TASK in "${TASKS[@]}"
do
  for SETUP in "${SETUPS[@]}"
  do
    python -m timeit -s "$SETUP" -n 1000 "$TASK"
  done
done

Results

Tested on ancient dual core laptop with Debian 8 and Python 2.7.13 Values are best of 3, msec per loop
