  The research designs a new integrated system for the security enhancement of
a decentralized network by preventing damages from attackers, particularly for
the 51 percent attack. The concept of multiple layered design based on
Blockchain Governance Games frameworks could handle multiple number of networks
analytically. The Multi-Layered Blockchain Governance Game is an innovative
analytical model to find the best strategies for executing a safety operation
to protect whole multiple layered network systems from attackers. This research
fully analyzes a complex network with the compact mathematical forms and
theoretically tractable results for predicting the moment of a safety operation
execution are fully obtained. Additionally, simulation results are demonstrated
to obtain the optimal values of configuring parameters of a blockchain-based
security network. The Matlab codes for the simulations are publicly available
to help those whom are constructing an enhanced decentralized security network
architecture through this proposed integrated theoretical framework.
