Why scaling solves blockchain limitations - See It in Action

Why Scaling Solves Blockchain Limitations

📖 Scenario: Imagine you run a small bakery that uses a simple ledger to track sales. As more customers come, your ledger gets crowded and slow. This is like a blockchain facing limits when many people use it. Scaling helps by making the ledger faster and able to handle more sales.

🎯 Goal: You will create a simple program that simulates a blockchain ledger with transactions. Then, you will add a scaling factor to show how increasing capacity helps handle more transactions efficiently.

📋 What You'll Learn

Create a dictionary called ledger with 3 transactions and their amounts

Create a variable called scaling_factor and set it to 2

Use a dictionary comprehension to create a new dictionary scaled_ledger where each transaction amount is multiplied by scaling_factor

Print the scaled_ledger dictionary

💡 Why This Matters

🌍 Real World

Blockchains face limits when many users make transactions. Scaling helps by increasing capacity so more transactions can be processed quickly.

💼 Career

Understanding scaling is important for blockchain developers and engineers to build efficient and fast blockchain systems.

1

Create the initial ledger with transactions

Create a dictionary called ledger with these exact entries: 'tx1': 100, 'tx2': 200, 'tx3': 300

Blockchain / Solidity

# Create the ledger dictionary with 3 transactions
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with keys and values.

2

Add a scaling factor

Create a variable called scaling_factor and set it to 2

Blockchain / Solidity

ledger = {'tx1': 100, 'tx2': 200, 'tx3': 300}
# Create the scaling_factor variable
# Your code here

Need a hint?

Just assign the number 2 to the variable scaling_factor.

3

Scale the ledger transactions

Use a dictionary comprehension to create a new dictionary called scaled_ledger where each transaction amount in ledger is multiplied by scaling_factor

Blockchain / Solidity

ledger = {'tx1': 100, 'tx2': 200, 'tx3': 300}
scaling_factor = 2
# Create scaled_ledger using dictionary comprehension
# Your code here

Need a hint?

Use {key: value for key, value in dict.items()} and multiply each value by scaling_factor.

4

Display the scaled ledger

Write print(scaled_ledger) to display the scaled transactions

Blockchain / Solidity

ledger = {'tx1': 100, 'tx2': 200, 'tx3': 300}
scaling_factor = 2
scaled_ledger = {tx: amount * scaling_factor for tx, amount in ledger.items()}
# Print the scaled_ledger dictionary
# Your code here

Need a hint?

Use the print function to show the dictionary.
