Interestingly, this brand-new custom coin they're using is not Proof-of-Work or Proof-of-Stake.

> The MobileCoin Consensus Protocol avoids the environmentally-damaging mathematical “work” required by Proof-of-Work (PoW) consensus protocols like Bitcoin and realizes a much higher transaction rate than the Bitcoin consensus protocol. In contrast to Proof-of-Stake (PoS) consensus protocols, practical control of governance in MCP is ceded to the users who are trusted the most by the extended MobileCoin community, rather than to the wealthiest users who control the largest financial stakes.

So it is POT. Proof of Trust. If you break it, it is crackpot and goes up in smoke /s

I am not familiar with this Quorums consensus mechanism, but in general I feel - especially given the scammy veil surrounding the entire field - that it is quite early to adopt such as-yet unproven technology in production software that is widely used by people where security and privacy (among others) is utterly important.

They are using Byzantine Fault Tolerant Quorums. That is just a class of majority election algorithms that is tolerant to the presence of evil participants. But in short, it is just the majority of servers allowed to vote, so either proof of stake or a cartel. What they neglected to specify is the difference there: "who is allowed to vote?"
