Homework on Blockchain and Mining Visually - Questions
-
Why is it important that the blocks are cryptographically linked together?
Immutability. This prevents modification of individual older blocks, double spending. It promotes integrity of the entire chain. -
What does the block structure look like in bitcoin?
Block is composed of:
Nonce
- Data (transactions, fees, rewards)
- Previous hash
=hash of the block
The next block is composed of:
Nonce
- Data (transactions, fees, rewards)
- Previous hash
=has of the new block
So all blocks are linked to all other blocks
