Or maybe just have one machine filter transaction/block traffic and only pass along valid transactions/blocks, and not have the rest of the machines even bother checking signatures. @p{par} It will be tougher for individual nodes. If they're not mining, they could just check signatures ONLY on somebody-sent-to-them transactions. @p{par} If they are mining... well, it seems to me single-node miners will become increasingly rare as bitcoin scales up. Hardware farms or miners using a mining pool seem like the way of the future. @p{brk}
