Block - correct answer A block is an individual transaction or piece of data that is
being stored within the blockchain.
Blockchain - correct answer A blockchain is a continuously growing list ("chain") of
records ("block"), called blocks, which are linked chronologically and secured using cryptography.
Blockchain Network - correct answer The blockchain network and blockchain are
terms used interchangeably. They represent the entire blockchain from the structure itself to the
network that it is a part of.
Decentralization - correct answer The concept in which participants work together
to validate transactions without relying on a central authority.
Participant - correct answer A client that owns a copy of the blockchain and verifies
transactions across the network.
Timestamp - correct answer - Property in a block
- The time the block is created determines the location of it on the blockchain.
Transaction Data - correct answer - Property in a block
- The information to be securely stored in the block.
Hash - correct answer - Property in a block
- A unique code produced by combining all the contents within the block itself — also known as a digital
fingerprint.
, Previous Hash - correct answer - property in a block
- Each block has a reference to the block prior to its hash. This is what makes the blockchain unique
because this link will be broken if a block is tampered with.
Deterministic - correct answer The same input will always produce the same
output, but that output cannot produce the original input.
Hash - correct answer A calculated string of letters and numbers produced from a
specific input.
Hash Function: - correct answer A function that takes in an input of a random size,
performs hashing on the input, and generates a seemingly random output of a fixed size, also known as
the hash.
Genesis Block - correct answer The genesis block is the first block on the blockchain
and it is typically hard-coded into the blockchain structure. Being the first block on the blockchain, it
does not have a link to a previous hash.
Which of the following actions does NOT change the current block's hash?
A. Modifying the transactions in the current block
B. Modifying the timestamp of the current block
C. Modifying the previous hash component of the following block
