- It is important because it deters the chance of transactions being changed. Keeps the blockchain solid or strong.

Why is it important that the blocks are cryptographically linked together?
this way if an old block is changed, it will invalidate all of the blocks that come after it -
What does the block structure look like in bitcoin?
block contains the previous block’s hash, the transactions, the nonce and the current block’s hash

It is important that blocks are cryptographically linked together to secure the blockchain. That way transactions can’t be changed in previous blocks. If this were to happen it would break the link to the next block and all that follow.
The Hash is based on the previous Hash, TX list and Nonce correctly guessed.

- Because if the weren’t, someone would be able to change a previous transaction without anyone knowing. Since they’re linked, a past change would change the current block
- Previous hash, transaction list, nonce

It is important for the security of the blockchain, so that nobody can make changes to a block without breaking the link to the following blocks.
-
The block structure is composed of the nonce, transaction data and the previous block hash, these three combined make up the block hash.

There are no confirmations on the block, this is just the number of blocks that have been mined after the said block.
I don’t really know what you mean by bits and transaction volume and the block and fee reward are part of the coinbase tx in the transaction data.
Also more importantly you forgot to mention the previous block hash which is important because its what links the blocks in a chain

In order to increase the security and bitcoin blockchain’s inmutability. If there’s a node’s change, not only becomes invalid due to a change in the hash, but also all the subsequent nodes are invalid as well. -

It contains the previous block’s hash, the UTXIOs and the NONCE.

1: Linking cryptography blocks together is the foundational function of Blockchain, without blocks linked together data in the system would be easy to manipulate & subsequently lose it’s integrity & security.
2: Each block is made up of transactional data, unique hash from the previous block & a nonce which is used to create a unique hash for the current block using a mathematical computing process called mining.

- it is important for the blocks to be cryptographicall linked together for the security of the blockchain. There will be no double spend. It makes it immutable
2.BTC block structure has 1) previous hash 2) transactions 3) nonce. The current hash is based on all of these factors

- This is important because each hash is created using the previous hash so that someone cannot change a previous block without changing the previous hash and subsequentially changing every hash after that.
- The bitcoin block structure includes the previous hash, a list of transactions, and the random nonce

The hash of the block is based on the transactions in the block plus the previous hash and the nonce that needs to be guessed.
Block number > Nonce > Transaction Data > Hash of the Previous Block > Hash of current block

- Because this makes the links more secure as the cryptographic hash functions are secure, anonymous, and unchangeable.
- A block is made of: the previous block’s hash, the transaction list, and a nonce.

To make it impossible to change data in the blocks. This means, that when one block is changed, all the blocks following it in the chain will have to be re-mined which is virtually impossible.

So that TX’s can’t be changed in older blocks as it would break the links to all blocks following it. -

It increases security: It makes sure that if someone wants to change a block, every single following block needs to be mined again and this is by far tooo expensive.

It consists of the hash of the previous block, the transactions and the nonce (number to guess).

To secure the blockchain, all blocks are linked together so if one block is changed all the blocks will be needed to re-mined and therefor it is practically impossible. - What does the block structure look like in bitcoin?
