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

Digital signatures, based on asymmetric-key cryptography, are widely used in blockchain technology to authenticate transactions and ensure their integrity. They allow users to verify the authenticity of a transaction without having access to the private key.

Multiple choice

What is the concept of a '51% attack' in the context of blockchain security?

  1. A malicious entity gaining control over a majority of the network's computing power

  2. A denial-of-service attack targeting blockchain nodes

  3. A phishing scam targeting cryptocurrency users

  4. A vulnerability in smart contract code that allows unauthorized access
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 51% attack refers to a scenario where a malicious entity gains control over a majority of the computing power in a blockchain network. This allows them to manipulate transactions, reverse transactions, and potentially double-spend cryptocurrencies.

Multiple choice

How does blockchain technology address the issue of double-spending in digital currencies?

  1. By using a distributed ledger system

  2. By employing proof-of-work consensus mechanism

  3. By implementing smart contracts

  4. By requiring users to hold their private keys securely
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Blockchain technology utilizes a distributed ledger system, where all transactions are recorded on multiple nodes across the network. This makes it virtually impossible for a single entity to manipulate or double-spend digital currencies.

Multiple choice

What is the role of smart contracts in enhancing blockchain security?

  1. They provide a secure way to transfer digital assets

  2. They enable the creation of decentralized applications

  3. They automate the execution of contractual agreements

  4. They protect blockchain networks from cyberattacks
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automate the execution of contractual agreements, ensuring that the terms are fulfilled without the need for intermediaries or enforcement mechanisms.
