Koin Mining Previously I said that miners or nodes would not be rewarded financially for work done. I've had a change of heart. Here I introduce how nodes can be rewarded for doing calculations. From now on to mine technically means to do these rewarded calculations. The koin network can have a optional secondary function on top of its normal blockchain functions. It could act as a super or artificial quantum computer by spreading calculations among all mining nodes. It would use a specialized programming language focused on this type of computing. Maybe some dynamic programming ability could also be built into this language. Such a language may already exist. The minimum cost of a procedure/command could be 10 or 100 times N. (N is calculated by dividing the most koin in one place by the procedures needed to break or solve for that address' private key.) When traffic is light, the network can accept requests for super-computing. Someone sends code to a node (and a second check node), paying in advance or along the way. The node then splits the tasks doing some work itself and paying other nodes to do the rest, starting a recursive process. Work that cannot easily be validated, could be sent to 2 nodes separately to check work. Nodes are reported for misrepresenting work. For large or many answers to intensive computing, nodes may need to temporarily store data on their hard drive. A map of how work was divided and where to retrieve answers could be given to the client. More payment could insure the keeping of data for a longer time. Perhaps nodes can choose their own price for work, so less expensive work is used first. Also available computing power could affect price, as well as network busyness. Notice however that the network more allows and supports than controls this extra functionality. I predict that a node that runs altruistically will be more trustworthy on the koin network. Maybe this could somehow be advantageous and come into play later. Voting rights could be given only to nodes who mine less than a certain threshold. Nodes could donate or micro-lend a portion of earnings to be counted as altruistic. I'm becoming convinced that providing for financial rewards may be necessary or beneficial, merging self-interest and altruism. (This way of thinking reminded me of Nash and Franklin.) This allows a way to cover electricity and other costs for more intensive nodes. The koin network could provide many advantages to this almost-independent function of distributed computing.
