An important consideration that is missing in section 7 A Blockchain Scheme is that the PoW must also be tied to the miner's receive address otherwise anyone could claim the reward as soon as the PoW was broadcast onto the network. A simple solution is to also hash the miner's receive address along with the previous block and transaction hash. This seems like a pretty major omission on the part of the authors and cas…
It's not so much missing, as it is implicit in the H(current block), since current block includes all transactions, includes the coinbase for the miner. (In reality, only the merkle root of the transaction tree is hashed, with similar effect).
Right, my mistake.
