How can you identify a block?

Every block consists of four fields -

The hash value of the previous block (thereby getting linked in a blockchain)

It contains details of several transaction data

It has a value called the nonce. The nonce is a random value which is used to vary the value of the hash in order to generate hash value less than the target

Hash of the block itself. It is the digital signature of the block and an alphanumeric value used to identify a block

The hash address is the unique identification of the block. It is a hex value of 64 characters that have both letters and digits. It is obtained by using the SHA - 256 algorithms.
