Thanks. Is the nonce also increasing across headers, or reset randomly for each new header?
If it is the former then what is to stop a miner privately adding a large initial value to the nonce before they start incrementing and trying values in a loop, in the hope of beating everyone else to the new header (albeit at the risk of missing a header for some smaller nonce value)?
Also, come to think of it, if a miner doing this is the first to find a new header, is it possible to determine if this is with the smallest nonce value larger than its initial value, so the miner didn't jump the gun? Or will any nonce value be fine so its up to a miner to decide where to start and hope to get lucky before anyone else?
There is no common header, each miner will be generating a different header based on the block they created. The miners are free to choose which transactions they include in the block and the timestamp will be different. The nonce can be any value, there are no restrictions.
