PyChain Ledger

Build a blockchain-based ledger system, complete with a user-friendly web interface

Update the provided Python file, which already contains the basic PyChain:

Create a new data class named Record. It a blueprint for the financial transaction records that the ledger blocks will store.
Modify the existing Block data class to store Record data.
Add Relevant User Inputs to the Streamlit interface.
Test the PyChain Ledger by Storing Records.

Step 1 - Create new data class named 'Record"

@dataclass

class Record:

sender: str
receiver: str
amount: float

Step 2 - Modify existing 'Block data class to store 'Record' data

class: Block

record: Record

Step 3 - Add relevent User Imputs to the Streamlit Interface

sender = st.text_input("Sender")

receiver = st.text_input("Receiver")
amount = st.text_input("Amount")

new_block = Block(

    record=Record(sender, receiver, amount),
    # data=input_data,
    creator_id=42,
    prev_hash=prev_block_hash
)

pychain.add_block(new_block)
st.balloons()

Step 4 - Test the PyChain Ledger by Storing Records

How it Works

There are three user imputs:

Sender
Receiver
Amount

This information is store in a dictionary and is stored as a Record in the Blockchain. Each block contains intormation about the transaction along with the time of the tranaction, id of the person minting the transaction, the hash of the previous tranaction and the nonce. These transactions are then validated to confirm that it is legitimate.
