Why scaling solves blockchain limitations - Quick Recap

Recall & Review

beginner

What is a common limitation of blockchain networks that scaling aims to solve?

Blockchain networks often face slow transaction speeds and high fees due to limited processing capacity. Scaling helps increase this capacity to handle more transactions efficiently.

How does increasing transaction throughput improve blockchain usability?

Higher throughput means the blockchain can process more transactions per second, reducing delays and making it practical for everyday use like payments or apps.

What is the difference between on-chain and off-chain scaling?

On-chain scaling improves the blockchain itself (like bigger blocks), while off-chain scaling moves some work outside the main chain (like payment channels) to reduce load.

Why does scaling help reduce transaction fees on a blockchain?

When more transactions can be processed quickly, there is less competition to get included in blocks, which lowers fees users pay to prioritize their transactions.

advanced

What role does decentralization play when scaling a blockchain?

Scaling must balance increasing capacity without making the network too centralized, so it stays secure and fair for all users.

What problem does blockchain scaling primarily address?

A Slow transaction processing and high fees

B Lack of encryption

C Insufficient user interface design

D Poor internet connectivity

Scaling focuses on improving transaction speed and reducing fees by increasing network capacity.

Which of the following is an example of off-chain scaling?

A Increasing block size

B Using payment channels

C Adding more nodes to the network

D Changing consensus algorithm

Payment channels move transactions off the main blockchain to reduce load, which is off-chain scaling.

How does scaling affect transaction fees on a blockchain?

A Fees increase as more users join

B Fees stay the same regardless of scaling

C Fees decrease because more transactions fit in blocks

D Fees become unpredictable

Scaling allows more transactions per block, reducing competition and lowering fees.

What is a risk when scaling a blockchain too much on-chain?

A Network becomes too slow

B Blocks become too small

C Users lose their private keys

D Network becomes too centralized

Making blocks too big or requiring heavy resources can centralize control to fewer nodes.

Why is decentralization important when scaling blockchain?

A To keep the network secure and fair

B To increase transaction fees

C To reduce the number of users

D To make the blockchain private

Decentralization ensures no single party controls the network, maintaining security and fairness.

Explain in simple terms why blockchain networks need scaling and how it helps solve their limitations.

Think about how a busy road needs more lanes to avoid traffic jams.
