This flow shows starting from the basics of Bitcoin and Ethereum, then comparing their key features to understand their differences.

Execution Sample

Blockchain / Solidity

bitcoin = {
  'purpose': 'store of value',
  'consensus': 'Proof of Work',
  'max_supply': 21000000
}

ethereum = {
  'purpose': 'programmable platform',
  'consensus': 'Proof of Stake',
  'max_supply': 'no fixed limit'
}

This code defines simple dictionaries showing key differences between Bitcoin and Ethereum.

Execution Table

Step	Variable	Key	Value	Explanation
1	bitcoin	purpose	store of value	Bitcoin is mainly digital gold for value storage
2	bitcoin	consensus	Proof of Work	Bitcoin uses energy-intensive mining to secure network
3	bitcoin	max_supply	21000000	Bitcoin has a fixed supply limit of 21 million coins
4	ethereum	purpose	programmable platform	Ethereum allows building apps with smart contracts
5	ethereum	consensus	Proof of Stake	Ethereum uses a more energy-efficient consensus method
6	ethereum	max_supply	no fixed limit	Ethereum does not have a capped supply
7	-	-	-	Comparison complete, differences identified

💡 All key features compared, execution ends.

Key Moments - 3 Insights

Why does Bitcoin have a fixed supply but Ethereum does not?

Bitcoin was designed as digital gold to store value, so it has a capped supply (see execution_table rows 3 and 6). Ethereum focuses on being a platform for apps, so it does not limit supply.

What is the difference between Proof of Work and Proof of Stake?

Proof of Work (Bitcoin) requires miners to solve puzzles using energy (row 2). Proof of Stake (Ethereum) selects validators based on coin ownership, using less energy (row 5).

Why is Ethereum called a programmable platform?

Because Ethereum supports smart contracts that let developers build apps, unlike Bitcoin which mainly stores value (rows 1 and 4).

Visual Quiz - 3 Questions

Look at the execution table, what is Bitcoin's consensus mechanism at step 2?

A Delegated Proof of Stake

B Proof of Stake

C Proof of Work

D Proof of Authority

💡 Hint

Check execution_table row 2 under 'Value' column.

At which step does Ethereum's max supply get defined?

A Step 5

B Step 6

C Step 4

D Step 3

💡 Hint

Look at execution_table row 6 for 'max_supply' key.

If Ethereum switched to Proof of Work, which step's value would change?

A Step 5

B Step 2

C Step 3

D Step 6

💡 Hint

Ethereum's consensus is set at step 5 in execution_table.

Concept Snapshot

Ethereum vs Bitcoin Differences:
- Bitcoin: store of value, Proof of Work, max 21M coins

- Ethereum focuses on flexibility and apps
- Consensus method affects energy use and speed

Full Transcript

This visual execution compares Ethereum and Bitcoin by defining their key features step-by-step. Bitcoin is shown as digital gold with a fixed supply and Proof of Work consensus. Ethereum is shown as a programmable platform with Proof of Stake consensus and no supply limit. The execution table tracks each feature assignment. The variable tracker shows how the dictionaries build up. Key moments clarify common confusions about supply limits, consensus methods, and platform purpose. The quiz tests understanding of these differences by referencing the execution table steps. This helps learners see exactly how Ethereum and Bitcoin differ in design and function.
