BLOCK WINDOW MODULE HAVING AGREEMENT ALGORITHM FOR LIMITING MINING, MANAGEMENT SERVER, AND VIRTUAL MONEY TRADING SYSTEM AND METHOD

摘要

The present invention provides a blockchain-based virtual money trading system and a method therefor, wherein the system includes a block window module having an agreement algorithm that is for limiting mining and that provides a certain limit to mining attempts after a specific proof-of-work cycle with respect to a system mining node, a general node, and a mining node. The block window module comprises: a mining history management unit for recording mining history information in association with a mining attempt result of a mining node and the corresponding mining node; and a block window generation unit for configuring a block window for, with respect to at least a portion of mining nodes that have achieved mining success, invalidating a mining attempt result or prohibiting a mining attempt for a certain period. The block window module further includes: a block window size calculation unit for calculating a block window size based on the mining history information so as to provide the block window; and a trading history management unit for providing virtual money trading history information between general nodes at the current time or for a recent particular period. Therefore, the present invention can effectively prevent a mining monopoly or oligopoly of a small number of mining nodes.
