Security Transfer Analysis of Inter-Blockchain Consensus Algorithm Including Slashing in Delay-Tolerant Payment Networks

The polar region communication network is modeled as a delay-tolerant payment channel network and a multi-path routing system is assumed to operate. Among the most appropriate models for sharing and managing such collected scientific and technological information, a distributed ledger-based information distribution service model would be one. In this paper, we analyzed the delay-tolerant payment channel network based on a partially <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\Delta$</tex>-synchronized blockchain model. In this study, we analyze how communication network delay can affect the delay-tolerant payment channel protocol. For the security transfer analysis of the blockchain-to-blockchain consensus algorithm, we assume that the protocol including slashing operates in a partially <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\Delta$</tex>-synchronous and permission-less setting. This paper proposes upper bounds of the attacker's share and safe areas according to private attacks in a delay-tolerant communication network situation.
