🔗 Python implementation and building blocks for blockchain

Pyzantium is a python module that let you implement blockchain whit various capabilityies in your project.

The Module provide both high-level(Blockchain) and low-level(Block,Consensus, ...) classes in order to be highly customizable.

1. Installation

The package is pip installable:

pip install pybchain

Or, you can download it and use setuptools to build it by hand:

git clone http://github.com/rezamahdi/pybchain
cd pybchain
python setup.py install

2. Usage

To initialize a blockchain, you must specify some info as agreement:

• Hash algorithm to use in blockchain.
• Wath type of data you want to store. Blockchain is capable of storing anythin not only transactions.
• An authentication scheme. Common way to do this is using ECC. this part is optional.
• Endpoint to connect to other nodes. Common option is a HTTP api or json-rpc.

Whit having these options specified, you can initialize the node as this:

from pyzantium import Chain, Block
from pyzantium.storage import Disk
from hashlib import sha_256

chain = Chain(
  hash=sha_256,
  storage=Disk(
    "path/to/storage",
    create=True
  )
)

Next, in order to mine genesis block do this:

genesis = Block(chain)
genesis.add_part(b'000000000000000000000000000')  # or any other type of data.
# add more data parts...
genesis.finalize()  # we don't use `mine` because it is named `forge` in PoS.

result = endpoint.broadcast_new_block(genesis)

if result.is_ok():
  chain.append(genesis)
