Simple Blockchain Implementation

This is a simple implementation of a blockchain using Python. The code defines a Block class that creates a basic blockchain structure and generates a hash for each block using the SHA-256 algorithm.

Overview

The Python script consists of the following components:

Block Class

The Block class represents a block in the blockchain. Each block contains:

• prev_hash: The hash of the previous block
• transaction: Details about the transaction
• amount: The amount related to the transaction
• hash: The hash of the current block
• time: Timestamp of the block creation

Methods

__init__

• Initializes the Block class with provided parameters and generates the block hash.

get_data

• Returns the data associated with the block.

make_hash

• Creates a hash for the block using SHA-256.

add_data

• Adds new data (transaction, amount) to the blockchain.

print_blocks

• Prints the information of all the blocks in the blockchain.

Usage

To use this code:

1. Initialize a block using Block(prev_hash, transaction, amount).
2. Add more data to the blockchain using add_data(transaction, amount).
3. View the details of the blockchain using print_blocks(block).

Example

test_block = Block('000746bd11a3a38ad2ac56a51cec7be5ce5930da347d8b31b5ef505568182a49', 'Ivan', 100)
test_block.add_data("Boris", 1042)
print_blocks(test_block)
