Multi-Layered Blockchain Governance Game [article]

Song-Kyoo Kim
2022 arXiv   pre-print
The concept of multiple layered design based on Blockchain Governance Games frameworks could handle multiple number of networks analytically.  ...  Additionally, simulation results are demonstrated to obtain the optimal values of configuring parameters of a blockchain-based security network.  ...  The simulation goes 1000 trials and find the optimal number of backup nodes based on the cost efficiency. It has been executed 4 times with 1000 trials and the optimal values vary (see Figure 5 ).  ...

Bitcoin Payment-channels for Resource Limited IoT Devices [article]

Christopher Hannon, Dong Jin
2018 arXiv   pre-print
This protocol enables IoT devices to open and maintain payment channels with traditional Bitcoin nodes without a view of the blockchain.  ...  In addition, we demonstrate the security and fairness of the protocol by formulating it as a game in which the equilibrium is reached when all players follow the protocol.  ...  On the other hand, if the Player 4 members collude with Player 1 (Strategy D), then they can receive some payoff γ2 K2 , where K 2 is the number of members in the group and γ 2 is the amount that Player  ...
