This flow shows how transactions are processed, what happens when capacity limits are reached, and how scaling solutions increase capacity to improve blockchain performance.

Execution Sample

Blockchain / Solidity

transactions = 1000
capacity = 500
if transactions > capacity:
    print('Scaling needed')
else:
    print('Processing transactions')

This code checks if the number of transactions exceeds the blockchain capacity and prints if scaling is needed.

Execution Table

Step	transactions	capacity	Condition (transactions > capacity)	Action	Output
1	1000	500	True	Print 'Scaling needed'	Scaling needed
2	-	-	End	Stop processing	-

💡 transactions (1000) exceed capacity (500), so scaling is needed and processing stops.

Variable Tracker

Variable	Start	After Step 1	Final
transactions	1000	1000	1000
capacity	500	500	500

Key Moments - 2 Insights

Why does the program print 'Scaling needed' instead of processing transactions?

Because the condition transactions > capacity is True at Step 1 in the execution_table, meaning the blockchain cannot handle all transactions at once.

What happens if transactions are less than or equal to capacity?

The else branch would run, printing 'Processing transactions', showing the blockchain can handle the load without scaling.

Visual Quiz - 3 Questions

Look at the execution_table, what is the value of 'transactions' at Step 1?

A 500

B 0

C 1000

D 1500

💡 Hint

Check the 'transactions' column in the execution_table at Step 1.

At which step does the program decide scaling is needed?

A Step 2

B Step 1

C No step, scaling is never needed

D Before Step 1

💡 Hint

Look at the 'Condition' and 'Action' columns in the execution_table.

If capacity was increased to 1500, what would the output be at Step 1?

A 'Processing transactions'

B 'Scaling needed'

C No output

D Error

💡 Hint

Compare transactions (1000) with new capacity (1500) in the condition.

Concept Snapshot

Scaling in blockchain means increasing capacity to handle more transactions.
If transactions exceed capacity, processing slows or fails.
Scaling solutions raise capacity, reducing wait times and fees.
This improves user experience and blockchain performance.
Check transaction count vs capacity to decide if scaling is needed.

Full Transcript

This visual execution shows how blockchain processes transactions and what happens when the number of transactions exceeds the blockchain's capacity. Initially, 1000 transactions arrive but the blockchain can only handle 500 at once. The program checks if transactions are greater than capacity. Since 1000 is greater than 500, it prints 'Scaling needed' and stops processing. This means the blockchain needs scaling to handle more transactions. If capacity were higher than transactions, it would process them normally. Scaling increases capacity and speed, reducing delays and fees, improving user experience.
