Where contests or tournaments are supported, the system maintains and backs up for each one its name, the date and time it occurred or will occur, each registered player's ID, name, entry fee and payment date, each winner's ID, name, amount and payment date, total entry fees and winnings including bonus credits, commission or fees, and the status.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
