Are miners generating POW hashes based off of the block header or is it just guess and check?

1 Answer 1


Partially. A block hashing blob is constructed which includes the block header, a miner coinbase transaction, a merkle tree root hash of the blocks transaction hashes, and a count of the transactions. This is updated with a nonce and only then hashed and checked.
