A block is a bunch of transactions that have been added to the blockchain. Each block consists of a header section and a body section. The body section of the block may consist of the list of transactions.
The header section of the block may consist of the following information:
- version – the current version of the block structure
- previous block header hash – the reference this block’s parent block
- merkle root hash – a cryptographic hash of all of the transactions included in this block
- time – the time that this block was created
- nBits – the current difficulty that was used to create this block
- nonce (“number used once”) – a random value that the creator of a block is allowed to manipulate however they so choose
