Crawling the MobileCoin Quorum System
Charmaine Ndolo, Sebastian Henningsen, Martin Florian
TL;DR
This paper presents a method for crawling the MobileCoin network to analyze its quorum configurations, revealing the control distribution among organizations and the system's safety-oriented design choices.
Contribution
It introduces a crawl methodology for MobileCoin, providing empirical insights into its quorum system and control distribution among organizations.
Findings
MobileCoin quorum system involves 7 organizations controlling 10 validator nodes.
Quorum configurations prioritize safety over liveness.
Some organizations and ISPs can potentially block new block approvals.
Abstract
We continuously crawl the young MobileCoin network, uncovering the quorum configurations of core nodes and the quorum system resulting from these configurations. This report discusses our crawl methodology, encountered challenges, and our current empirical results. We find that the MobileCoin quorum system currently comprises of 7 organisations controlling a total of 10 validator nodes. Current quorum set configurations prioritise safety over liveness. At the time of writing, one of the involved organisations is technically able to block the approval of new blocks, as is the case for one of the (two) ISPs employed by crawled nodes.
