Test

• Test1.py, This test just creates the genesis block of the blockchain.
• Test2.py, This test add a one block to the blockchain and prints the blocks.
• Test3.py, This test add 2 blocks into the blockchain, prints the blocks and validate the blockchain.
• Test4.py, This shows all the blocks.

Install

From official pypi.org

python -m pip install BlockchainDataBase

From test.pypi.org

python -m pip install --index-url https://test.pypi.org/simple/ BlockchainDataBase

Configuration

On the folder you found a configuration file in a JSON format, if you want to change the folder on the database or database name you do in this file.

# The data saves on %APPDATA% directory.

Examples

Initialize the Blockchain.

from BlockchainDataBase.Blockchain import Blockchain

bc = Blockchain()

Add one block into Blockchain.

data = {"Data": "dataResult"}
bc.add_block(data)

Shows all the blocks in the Blockchain.

bc.print_blocks()

Validates the blockchain to check if not was corrupted

bc.validate_chain()
