Question

What is a block hash?

Answer 1

A block hash is a unique identifier that is generated for each block in a blockchain. It is a cryptographic hash function that represents the content of the block, including the transaction data, timestamp, and the hash of the previous block in the chain. The block hash is used to uniquely identify and secure each block in the blockchain network.

Answer 2

A block hash is a cryptographic hash value calculated for a block in a blockchain. It is generated by running the block's data through a specific hash function. The block hash uniquely identifies the block and is used to link it to the previous block in the blockchain, ensuring the integrity and security of the entire blockchain network.
