Is the hash that defines the previous block (block A) in a new block (block B), the same as the hash the miner calculated to submit block A?
As far as I know, you need to find a nonce so that the hash of the entire block A starts with zeroes. If you find a fitting nonce is this hash with the zeroes used by the next miner in his block b when he links to your block with the previous hash?
To clarify, if person A found a nonce so that the hash of his block is 000231 is the hash in the previous field of the next block also 000231?
Thanks
