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

A blockchain is composed of a series of blocks, each containing a set of transactions, a cryptographic hash of the previous block, and a timestamp.

Multiple choice

What is the process of adding a new block to the blockchain called?

  1. Mining

  2. Hashing

  3. Validation

  4. Consensus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mining is the process by which new blocks are added to the blockchain. Miners solve complex mathematical problems to validate transactions and add them to the blockchain.

Multiple choice

What is the role of a hash function in blockchain?

  1. To encrypt data

  2. To generate unique identifiers

  3. To verify the integrity of data

  4. To facilitate consensus among nodes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A hash function is used in blockchain to generate a unique and irreversible fingerprint (hash) of a block. This hash is used to verify the integrity of the data in the block and to link it to the previous block, ensuring the immutability of the blockchain.

Multiple choice

Which consensus mechanism is commonly used in permissionless blockchains?

  1. Proof-of-Work (PoW)

  2. Proof-of-Stake (PoS)

  3. Delegated Proof-of-Stake (DPoS)

  4. Proof-of-Authority (PoA)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Proof-of-Work (PoW) is a consensus mechanism commonly used in permissionless blockchains like Bitcoin. In PoW, miners solve complex mathematical problems to validate transactions and add them to the blockchain.

Multiple choice
