Eclipse Attack Detection on a Blockchain Network as a Non-Parametric Change Detection Problem

arXiv:2404.00538v1 Announce Type: new
Abstract: This paper introduces a novel non-parametric change detection algorithm to identify eclipse attacks on a blockchain network; the non-parametric algorithm relies only on the empirical mean and variance of the dataset, making it highly adaptable. An eclipse attack occurs when malicious actors isolate blockchain users, disrupting their ability to reach consensus with the broader network, thereby distorting their local copy of the ledger. To detect an eclipse attack, we monitor changes in the Fr\'echet mean …
