  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.
