What is the role of smart contracts in blockchain technology?

  1. Self-executing contracts with the terms of the agreement directly written into lines of code

  2. Contracts that are enforced by a central authority

  3. Contracts that are stored on a blockchain

  4. Contracts that are used to facilitate transactions between two parties
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code, which are stored on a blockchain and executed automatically when certain conditions are met.

Multiple choice

What is the difference between a public blockchain and a private blockchain?

  1. Public blockchains are open to anyone, while private blockchains are restricted to a specific group of participants

  2. Public blockchains are more secure than private blockchains

  3. Public blockchains are more scalable than private blockchains

  4. Public blockchains are more expensive to operate than private blockchains
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Public blockchains are open to anyone to participate in, while private blockchains are restricted to a specific group of participants, typically a consortium of organizations.

Multiple choice

What is the consensus mechanism used in Bitcoin?

  1. Proof-of-Work (PoW)

  2. Proof-of-Stake (PoS)

  3. Delegated Proof-of-Stake (DPoS)

  4. Practical Byzantine Fault Tolerance (PBFT)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bitcoin uses the Proof-of-Work (PoW) consensus mechanism, which requires miners to solve complex mathematical problems to validate transactions and add new blocks to the blockchain.

Multiple choice

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cryptocurrencies play multiple roles in blockchain technology, including rewarding miners for their work, facilitating transactions, and storing value.

Multiple choice

What is the Lightning Network?

  1. A second-layer solution that enables faster and cheaper transactions on the Bitcoin blockchain

  2. A decentralized exchange for trading cryptocurrencies

  3. A platform for developing decentralized applications

  4. A blockchain-based voting system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Lightning Network is a second-layer solution that enables faster and cheaper transactions on the Bitcoin blockchain by allowing users to open payment channels and conduct transactions off-chain.

Multiple choice

What is the difference between a blockchain and a hashgraph?

  1. Blockchains use a proof-of-work consensus mechanism, while hashgraphs use a gossip protocol

  2. Blockchains are public, while hashgraphs are private

  3. Blockchains are more scalable than hashgraphs

  4. Hashgraphs are more secure than blockchains
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Blockchains use a proof-of-work consensus mechanism, which requires miners to solve complex mathematical problems to validate transactions and add new blocks to the blockchain, while hashgraphs use a gossip protocol, which allows nodes to communicate with each other and reach consensus on the order of transactions.

Multiple choice
