volume Networkis also known as Turbo Network, which is committed to building large-scale cryptocurrencies that are applied in real business society. Turbo use the POST consensus mechanism, and POST is an operator that introduces the time dimension on the basis of the original spatial proof algorithm. Because of the uses of the characteristics of the deferrable verification function (DVF), is is mandatory for a miner to perform a certain time-strength mathematics obtaining candidate block data computing, they combined two factors that can quickly verify the results and the candidate block data, and when they select block, the problem of security ambiguity such as selfish mining and rewriting attacks in the POC algorithm is totally solved
