receive a packet of 0.5mb with Graphene. Do you see what I mean? In the end the blocksize ( written to HDD) will be 28mb, the TXs will have paid whatever fees they wanted, but this is
not what Graphene is about. Graphene help nodes communicate blocks faster because most of them have the same mempool of TXs. So you don't have to re-download all the TXs in the block.
